An embodiment of the present invention relates to a system for supporting appreciation of works of art. Note that, in this application document, the term “system” may include one or a plurality of information processing apparatuses. The information processing apparatus is explained below. In this application document, the term “work of art” may be a term of a superordinate concept of various works of art such as a painting, an engraving, a garden, a craft, a ceramic art, a photograph, architecture, a flower arrangement, a painting, origami, and an ukiyo-e and may be a term of a superordinate concept of various things such as literature, design, and a comprehensive art. 
     2. FUNCTIONS OF A SYSTEM ACCORDING TO ONE EMBODIMENT 
     A system according to an embodiment of the present invention may include a part or all of a database unit, a first access providing unit, a second access providing unit, and a third access providing unit explained below. 
     2.1. Database Unit  21   
     The database unit has a function of managing a database. The database unit may be configured from one or a plurality of databases. The database unit may have a function of managing information such as addition and/or deletion of information with respect to the one or the plurality of databases. 
     The database unit may store a part or all of first art data. 
     The database unit may be connected to an internal database as a part of components of the system or may be connected to an external database other than the components of the system. In the latter, an example system may be capable of cooperating with an external local database unit including one or a plurality of databases. 
     An internal or external example local database unit to which the database unit is connectable may store work of art information about works of art correlating with a first art facility. 
     The work of art information may include, for example, information relating to a work of art itself, information relating to a creation place of the work of art, information relating to a creator of the work of art, information relating to a type of the work of art, and/or information relating to a creation period of the work of art. 
     The information relating to the work of art itself may include one or a plurality of image files obtained by imaging the work of art. The image file may be an image file obtained by imaging the work of art from various directions according to the nature of the work of art. For example, if the work of art is a painting, the image file may be an image file captured from the front of the painting. However, if the work of art is three-dimensional, the image file may be one or a plurality of image files obtained by imaging such a three-dimensional work of art from one or a plurality of directions that can be interpreted as the front or obtained by imaging such a three-dimensional work of art from various directions other than the front such as the side, the rear, the upper side, and/or the lower side. The image file may be an image file obtained by imaging the entire work of art and/or may be an image file obtained by imaging only one or a plurality of specific parts in the work of art. The image file may have image files having different numbers of pixels, different image qualities, and the like respectively for the same imaging target in the work of art. 
     The information relating to the creation place of the work of art may include a country, an area, and the like where the work of art is created. 
     The information relating to the creator of the work of art may include information relating to the creator. For example, the information may include information included in a biographic table of the creator such as a name and nationality of the creator and a community to which the creator belongs. The person chronology may include a date of birth, a date of death, and the like. 
     The information relating to the type of the work of art may be information in a field to which the work of art belongs in the art history. 
     The information relating to the creation period of the work of art may be a creation start period, a creation end period, and the like. 
     The internal or external example local database unit to which the database unit is connectable may store information relating to social activities for works of art served for browsing in the first art facility. The information relating to social activities for works of art may include evaluation information, trade information, restoration information, and/or management information for the works of art. 
     Since the database unit stores such information relating to the social activities for works of art, there is an advantage that a person who can access such information can easily use the information for researches about such works of art themselves and researches about relations with other works of art. 
     The evaluation information about the work of art may be information obtained by evaluating the work of art. For example, the evaluation information may be information of various media such as a newspaper article, a magazine, a journal, a book, a movie, a drama, and the like on which critiques by critics are posted. The evaluation information may be information of such contents converted into a file. 
     The management information about the work of art may be a part or all of information relating to transactions from a point in time when the work of art is created by the creator to the present. The management information about the work of art may be, for example, a seller, a purchaser, an intermediary, a lender, a borrower, a sales/purchase date, a rent date, a return date, a sales/purchase place, a transaction amount, a sales/purchase market, information indicating sales, information related to other sales, and the like about the work of art. The information indicating trade may be a purchase slip, a receipt, living things used at the time of custom clearance, a document used for transportation, or the like. The information relating to buying and selling may be, for example, information concerning an advertisement for buying and selling the work of art, information of an auction, information indicating the buying and selling, or the like. For works of art, there is an advantage that it is possible to determine the authenticity of such a work of art according to information concerning transactions from a creation point in time to the present. Note that, for all works of art, not all of information concerning transactions from creation points in time to the present are always present. Even when a part of the information is missing, the information is still information for determining the authenticity of the works of art. In these kinds of information, for physical objects such as a purchase slip and a receipt, the information may be stored as a file in a form of an image captured by an imaging device. 
     The restoration information of the work of art may be information relating to restoration of the work of art. For example, the restoration information about the work of art may be a person who has restored the work, a restoration organization, a restoration place, a restoration time (for example, a restoration start time, a restoration end time, and a restoration period), and the like. 
     An internal or external local example database unit to which the database unit is connectable may store information served for commentary of a work of art provided in the first art facility. The information served for the commentary of the work of art may include sound, a moving image, and/or text. 
     The information served for the commentary of the work of art may be information for introducing the work of art to ordinary people, information for introducing the work of art to children, and/or information for explaining the work of art to experts of such a work of art. 
     The information served for the commentary of the work of art may be in various forms and may be, for example, a moving image, sound, a still image, and/or text. 
     The information served for the commentary of the work of art may include an image obtained by imaging the work of art. The image quality of the image obtained by imaging the work of art may be equal to or higher than predetermined image quality and may be the number of pixels as high as a degree enough for guaranteeing actual quality of the work of art. There is an advantage that deterioration can be prevented by imaging and digitizing the work of art. By imaging the work of art with a high number of pixels, there is an advantage that it is possible to store the work of art in a state close to a real state and it is possible to reproduce the work of art satisfactory for appreciation. 
     The information served for the commentary of the work of art may include text. Only the text may be able to be acquired from a given file and stored. Such stored text information may be used for an application on the WEB. 
     The internal or external example local database unit to which the database unit is connectable may store information relating to an event held in correlation with the first art facility. 
     The event held in correlation with the first art facility may be various entertainments held in the first art facility and may include, for example, an exhibition held in the first art facility, a seminar held in the first art facility, and an educational activity held in the first art facility. 
     Such information relating to the event may include various kinds of information. For example, information relating to one event may include a work of art use in such an event, materials for establishing the work of art used in such an event, and/or positioning of such an event in terms of art. The positioning of the event in terms of art may include, for example, information such as a specific era (classical, modern, etc.) to which the work of art is directed, a specific country (Japan, France, Italy, etc.) targeted by the work of art, and a specific artist targeted by the work of art. 
     The information relating to the event may include information concerning the event itself. The information concerning the event itself may include, for example, a holding period of the event (from a holding start date to a holding end date), a total number of participants in the event, an advertisement for the event, and information concerning evaluation for the event. 
     The internal or external local example database unit to which the database unit is connectable may store information relating to a work of art having a predetermined relationship with one work of art in the first art facility and/or the second art facility. Here, the work of art having the predetermined relationship with the one work of art may include a work of art created by a creator of the one work of art, a work of art created by a creator in a group to which the creator of the one work of art belongs, a work of art created in series with the one work of art, and/or a work of art created in the same period as a creation age of the one work of art. The information relating to the work of art having the predetermined relationship with the work of art may include, for example, information about an art facility that serves the work of art having the predetermined relationship with the work of art for browsing and/or information for explaining the work of art having the predetermined relationship with the work of art explained above. The work of art having the predetermined relationship with the one work of art explained above may include information for explaining the work of art having the predetermined relationship with the one work of art explained above in correlation with the one work of art in the first art facility and/or the second art facility. 
     An example system may include a main database unit. Such a main database unit may store a part or all of the information acquired from each of the internal or external database units explained above. A management unit of the main database unit may cooperate with the internal or external local database units explained above to store, at predetermined timing, in the main database unit, the information in the internal or external local database units. The predetermined timing for storing the information in the main database unit may be defined in various periods such as every day, every week, and every month. For the acquisition of the information in the internal or external local database units in the main database unit, a method of storing only a changed place in the external local database units in the main database unit may be adopted. 
     Further, the information in the main database unit in the example system may be searchable with an ID number correlated with one work of art. For example, when the database units explained above is provided from the outside, even when an implementation method for the database units is sometimes different and a cross-sectional search difficult, there is an advantage that efficient and cross-sectional search is enabled in the main database unit and necessary information can be acquired by storing only related information among the information of the external database unit in the main database unit as explained above. 
     When all of one or a plurality of local database units are external database units, the database unit in the system in the embodiment includes the main database unit but may not include the one or the plurality of local database units.

Since a plurality of functions can be configured by one information processing apparatus, for example, the first main database unit and a twelfth converter unit are configured by one information processing apparatus and the second main database unit and a twenty-third converter unit are configured by one information processing apparatus. Configurations are not limited to these and may be various configurations. The information processing apparatus that realizes the database may use various database technologies and various database models may be used. For example, there may be a relational data model, an object data model, a network type data model, a hierarchical data model, or the like. Various databases that implement such data models may be used. 
     Note that, for example, when a network connecting the first main database unit and the twelfth converter unit and a network of the second main database unit are made different, the data in the first main database unit and the data in the second main database unit can be physically different networks. Therefore, there is an advantage that confidentiality of the data in the first main database unit can be improved. In particular, when a firewall is set between the network connecting the first main database unit and the twelfth converter unit and the network of the second main database unit, it is possible to further control the transfer of data between the data in the first main database unit and the data in the second main database unit with the firewall. Therefore, there is an advantage that the confidentiality of the data can be improved. 
     Similarly, for example, when a network connecting the second main database unit and the twenty-third converter unit and a network of the third main database unit are made different, the data in the second main database unit and the data in the third main database unit can be physically different networks. Therefore, there is an advantage that the confidentiality of the data in the second main database unit can be improved. In particular, when a firewall is set between the network connecting the second main database unit and the twenty-third converter unit and the network of the third main database unit, it is possible to further control the transfer of data between the data in the second main database unit and data in a thirty-second main database unit with the firewall. Therefore, there as an advantage that confidentiality of data can be improved. 
     In the above explanation, the configuration in which the data in the third main database unit is acquired from the second main database unit is explained. However, together with or instead of such a configuration, the third main database unit and the first main database unit may be connected or a thirteenth converter unit may be provided between the third main database unit and the first main database unit and the thirteenth converter unit may change the content and/or format of the data in the first main database unit and transfer the data into the third main database unit. Similarly, when a network connecting the first main database unit and the thirteenth converter unit and the network of the third main database unit are made different or a firewall is set therebetween, there is an advantage that confidentiality of data can be improved as explained above. 
     2.2. First Access Providing Unit  22   
     The first access providing unit provides access to the database unit. The first access providing unit provides a first network. 
     The first access providing unit may provide access to, for example, the information processing apparatus in the first art facility via the first network. The information processing apparatus in the first art facility may be capable of accessing the first access providing unit. The information processing apparatus in the first art facility may be, for example, an information processing apparatus (in this application document, sometimes referred to as “information processing apparatus for a researcher or the like”) used by a person (in this application document, sometimes referred to as “researcher or the like”) who studies, investigates, and/or creates materials for works of art in the first art facility. Such materials may be materials for experts or materials for ordinary people. The materials for ordinary people may include materials for adults or may include materials for children. The first access providing unit may be accessible from, for example, only the information processing apparatus in the first art facility via the first network. In this case, data managed by the first access providing unit is provided from the information processing apparatus in the first art facility. There is an advantage that confidentiality can be improved. The first access providing unit may be accessible from, for example, only the information processing apparatus set in the first art facility via the first network. In this case, the data managed by the first access providing unit is provided from the information processing apparatus set in the first art facility. There is an advantage that confidentiality can be improved. 
     In the system in the embodiment, the first art data in the database unit may be usable from the information processing apparatus for the researcher or the like via the first access providing unit. The first art data may be, for example, the data explained above that is browsed, created, managed, and/or used by the researcher or the like. Such first art data may include materials created for experts about works of art or may include materials created for ordinary people about works of art. The materials for ordinary people may include materials for adults or may include materials for children. 
     Note that the first art data may include the second art data and may be a superordinate concept of the second art data. The second art data may be data changed or corrected based on the first art data. 
     The first art data may include the third art data and may be a superordinate concept of the third art data. The third art data may be data changed or corrected based on the first art data. 
     When the database unit includes the first main database, the first access providing unit may be connectable to the first main database. 
     A facility including works of art is one of ideal research environments where researches on the works of art can be deepened. However, in order to deepen the researches on the works of art, it is preferable that there are not only the works of art themselves but also various related research materials. Although researchers of works of art often have the most advanced knowledge about the works of art, it is preferable that, at an early stage, such knowledge can be provided to general audiences, that is, visitors who visit to appreciate the works of art. 
     Therefore, when the system in the embodiment includes the database unit and the first access providing unit is capable of managing, for example, browsing and storing of specialized materials for works of art from the information processing apparatus connectable to the first access providing unit is capable of managing, for example, storing and browsing of materials for ordinary people, there is an advantage that it is possible to deepen researches on the works of art and at the same time create materials that can provide such knowledge to ordinary people at an early stage. 
     The first access providing unit may provide a function of enabling setting about which of the first art data, the second art data, the third art data, the first art data and the second art data, the first art data and the third art data, and the first to third art data the data stored in the main database unit is. Only the first access providing unit may provide the function for enabling setting about which of the first art data, the second art data, the third art data, the first art data and the second art data, the first art data and the third art data, and the first to third art data the data stored in the main database unit is. The second access providing unit and the third access providing unit may not be able to provide such a function. In this case, there is an advantage that an accessible range for data to be stored can be set only from the information processing apparatus in the first art facility provided by the first access providing unit. Such data to be stored may be in units of files and/or in units of folders. In this case, there is an advantage that the accessible range can be set more precisely. 
     A method of providing information by the first access providing unit may be unicast, may be broadcast, or may be multicast. 
     As a trigger for the first access providing unit to provide information, for example, the information may be transmitted in response to a request from a terminal carried by a visitor or may be transmitted without requiring a request from such a terminal. The information may be transmitted at a timing corresponding to the request from the terminal or the information may be transmitted without requiring the request from the terminal or at timing unrelated to the request. 
     Hardware configuring the first access providing unit may be, for example, an information processing apparatus including a communication function. The communication function may be wireless communication or wired communication. The information processing apparatus including the communication function may be, for example, in wireless communication, an information processing apparatus capable of performing wireless LAN communication. For example, the information processing apparatus may be a Wi-Fi connection apparatus, a Bluetooth apparatus, a near field communication apparatus, or the like and a standard of the information processing apparatus may be IEEE 802.11, IEEE 802.15, or the like but is not limited to these standards. In wired communication, the information processing apparatus may be an information processing apparatus capable of performing Ethernet communication. Note that the information processing apparatus including the communication function may include functions such as a repeater, a bridge, and a router. 
     2.3. Second Access Providing Unit 
     The second access providing unit provides access to the database. The second access providing unit provides a second network. 
     The second access providing unit may provide access to, for example, the information processing apparatus in the second art facility via the second network. The information processing apparatus in the second art facility may be capable of accessing the second access providing unit. 
     The recent innovation of the information processing technology is remarkable. A period in which a most advanced device is substantially most advanced is about one to two months. Therefore, even if an art facility includes such a most advanced device and such a most advanced device included in the art facility is provided to visitors to the art facility, the device is not the most advance any more in a few months. Therefore, considering that a most advanced device is always provided in the art facility, an equipment burden is excessive large. Therefore, it is unrealistic to always provide the most advanced device. 
     When the system according to the embodiment includes the database unit and the second access providing unit, there is an advantage that, by providing an application to a latest portable information terminal (examples thereof include, but are not limited to, smart devices such as a smartphone, a tablet, a phablet, and a smartwatch) brought by a visitor to the art facility, appreciation of works of art can be supported by utilizing a most advanced device that the visitor can bring. In such a case, there is also an advantage that the visitor can appreciate the works of art by using a mobile terminal that the visitor usually uses and to which the visitor has attachment. Note that, when the second access providing unit provides access to the second art data based on materials created by researchers or the like concerning the works of art via the first access providing unit, as explained above, there is an advantage that the materials about the works of art created by the researchers or the like having knowledge concerning most advanced works of art can be opened to general people visiting the second art facility such as a museum and research results about the works of art can be opened to the public including the general people at an early stage. 
     The second network may be accessible by, for example, the information processing apparatus located in the second art facility. The information processing apparatus located in the second art facility may include, for example, an information processing apparatus set in the second art facility and usable by a visitor who visits the second art facility. The information processing apparatus located in the second art facility may include an information processing apparatus brought by the visitor who visits the second art facility. 
     The second access providing unit may be accessible only from, for example, the information processing apparatus in the second art facility via the second network. In this case, data provided by the second access providing unit is provided only to the information processing apparatus in the second art facility. There is an advantage that only the visitor who visits the second art facility can enjoy a merit of accessing the second art data. 
     The second access providing unit may provide the second art data in the database unit. The second art data may be, for example, materials created for ordinary people about works of art. The materials for ordinary people may include materials for adults or may include materials for children. 
     When the database unit includes the second main database, the second access providing unit may be connectable to the second main database. 
     The second art data may be accessible using Web API via the second network. 
     The WEB API may include various protocols that provide access to information such as HTML and CSV. When the system according to the embodiment enables access to information using the WEB API including various protocols for providing access to information, since the WEB API is a frequently used WEB API, there is an advantage that quick and flexible application development can be performed and adaptations to various new devices can be performed. 
     A method of providing information by the second access providing unit, a trigger for providing information by the second access providing unit, and/or hardware configuring the second access providing unit may be respectively the same as or may be different from those in the first access providing unit explained above. 
     When the first art facility and the second art facility are the same facility, the first network provided by the first access providing unit and the second network provided by the second access providing unit may be different networks. For example, in a museum as the same facility, the second access providing unit may provide a second network accessible in regions from the basement to the third floor and the first access providing unit may provide a first network accessible in regions of the fourth floor or an additional building. 
       2 . 4 . Third Access Providing Unit 
     The third access providing unit provides access to the database. The third access providing unit provides a third network. The third network may be the general Internet. 
     When the database unit includes the third main database, the third access providing unit may be connectable to the third main database. 
     A method of providing information by the third access providing unit, a trigger for providing information by the third access providing unit, and/or hardware configuring the third access providing unit may be the same as or different from those in the first access providing unit explained above. 
     3. SYSTEM ACCORDING TO THE EMBODIMENT 
     3.1. Configuration of the System According to the Embodiment 
     The system according to the embodiment may be a system including a main database unit, the main database unit being configured from a first main database unit to a third main database unit and including a first access providing unit that provides access to the first main database unit, a second access providing unit that provides access to the second main database unit, and a third access providing unit that provides access to the third main database unit.  FIG.  4    is an example of such a system. Here, the first main database unit may correspond to a meta database  401 A, the second main database unit may correspond to a museum database  401 B, and the third main database unit may correspond to a public database  401 C. 
     The first access providing unit may provide access to be connectable to the meta database (not illustrated). When the first access providing unit provides access to the meta database, there is an advantage that, for example, access can be made from an information processing apparatus for researchers or the like set in a first art facility, which is a facility where researchers or the like perform researches or the like and it is possible to access the first art data and perform researches about works of art or create materials. 
     The second access providing unit may provide access to the museum database via a museum DBAPI  402 A. When such a second access providing unit provides access to the museum database, for example, there is an advantage that a visitor who visits the second art facility such as a museum can access the second art data in the museum database using a most advanced information processing apparatus brought by the visitor. 
     The third access providing unit may provide access to the public database via a public DBAPI  402 B. When such a third access providing unit provides access to the public database, for example, there is an advantage that a visitor before or after visiting the second art facility such as a museum can access the third art data in the public database using the most advanced information processing apparatus brought by the visitor. 
     Here, App1 to m405 illustrate applications on information processing apparatuses brought by visitors to the museum and indicate that the visitors can access the public database outside the museum via a public DBAPI using information processing apparatuses usually used by the visitors and indicate that the visitors can access the museum database in the museum using the same information processing apparatuses usually used by the visitors. 
     When the system in the embodiment includes a metadata converter  403 A which is the twelfth converter, when data is stored in the museum database based on the data in the meta database, there is an advantage that content or a form of the data can be changed according to necessary, that is, about data satisfying a predetermined condition. For example, since the museum database stores data that can be opened to general visitors who visit the museum provided as the second art facility, it is sometimes unsuitable to open data in one file or data in one folder to be opened to the public. It is unsuitable to open the data to the public, for example, when a license for opening the data to the public is not obtained in terms of a contract. Therefore, when the data is stored in the museum database based on the data in the meta database, the data in the meta database may be directly moved to the museum database in some cases or the data after the metadata converter  403 A performs data change processing on the data in the meta database satisfying a predetermined condition based on a predetermined conversion rule may be moved to the museum database in other cases. With such a configuration, there is an advantage that such an appropriate adaptation can be enabled. Here, examples of the predetermined condition include inclusion of data not licensed for opening to the public. Examples of the corresponding predetermined conversion rule include changing processing for deleting the data not licensed or changing processing for changing the data to other data. In this way, the metadata converter  403 A, which is the twelfth converter, may generate the second art data in the museum database based on the first art data in the meta database. 
     In addition, when timing when the system according to the embodiment stores data in the museum database based on the data in the meta database is, for example, predetermined time every day, there is an advantage that the system can quickly change or correct the data opened to the public in the museum. 
     Similarly, when the system in the embodiment includes a museum data converter  403 B which is the twenty-third converter, when data is stored in the public database based on the data in the museum database, there is an advantage that content or a format of the data can be changed according to necessary, that is, for data satisfying a predetermined condition. For example, since data that can be opened to the outside on the Internet is stored in the public database, in some case, it is sometimes unsuitable to open data in one file or data in one folder to the public. It is unsuitable to open the data to the public, for example, when the data should be kept in opening in a museum from the contract point of view or an artistic point of view. Therefore, when the data is stored in the public database based on the data in the museum database, the data in the museum database may be directly moved to the public database in some case and the data after the museum data converter  403 B performs the data change processing on the data in the museum database satisfying a predetermined condition based on a predetermined conversion rule may be moved to the public database in other cases. As an example of such a case, for example, it is conceived that data of an image having resolution equal to or higher than first predetermined resolution that is captured for a certain work of art and can depict details is opened to the public in a museum. When storing such image data in the public database, the museum data converter may convert the resolution of such an image into image data having second predetermined resolution lower than the first predetermined resolution. This makes it possible to obtain the advantages explained above. In this way, the museum data converter  403 B, which is the twenty-third converter may generate the third art data in the public database based on the second art data in the museum database generated based on the first art data in the meta database. Note that, as another aspect, as explained above, the thirteenth converter may directly generate the third art data based on the first art data. 
     When timing when the system according to the embodiment stores data in the public database based on the data in the museum database is, for example, predetermined time every day, there is an advantage that it is possible to quickly change or correct data to be opened to the public. 
     The system in the embodiment may include a firewall  404 A between the network including the meta database and the network including the museum database. In this case, there is an advantage that access to information between the network including the meta database and the network including the museum database can be restricted and the security of the meta database can be improved. 
     The system in the embodiment may include a firewall  404 B between the network including the museum database and the network including the public database. In this case, there is an advantage that access to information between the network including the museum database and the network including the public database can be restricted and the security of the museum database can be improved. 
     The system according to the embodiment may perform, for example, display illustrated in  FIG.  5   . Explanation about such a system may be displayed. 
     The first main database unit may be connectable to the first to fifth local databases. Note that, in this figure, the first to fifth local databases are illustrated as local databases  4061  to  406   n.    
     A first local database may be a database that stores the various kinds of work of art information explained above. Such a database may be a commercial system and, for example, may be able to be logged in from a login screen illustrated in  FIG.  5   . Such a system may store various kinds of work of art information and may include a search function. For example,  FIG.  7    is an example of a display screen for the search function of such a database. 
     A second local database may be a database that stores information relating to the social activities for works of art explained above. For example, the second local database may be able to be logged in from a login screen illustrated in  FIG.  8   . Such a system may store various kinds of work of art information and may include a search function. For example,  FIG.  9    is an example of a display screen of the search function of such a database. 
     A third local database may be a database that stores information for explaining works of art explained above in a form of a photograph, sound, and a moving image.  FIG.  10    is an example of a screen on which information for explaining works of art is searched. In such a screen, an image obtained by imaging a work of art, a name of the work of art, a creator name, a classification, a work number, and an image, sound, and a moving image for explaining such a work of art are displayed in correlation with a work ID. Such a screen may be displayed based on the fact that such a database stores these data in correlation with each other. 
     A fourth local database may be a database that stores information served for commentary of works of art explained above in the text format explained above. For example, the fourth local database may be able to be logged in from a login screen illustrated in  FIG.  11   . Such a system may store information served for commentary of works of art in a text format and may include a search function. For example,  FIG.  12    is an example of a display screen of the search function of such a database. 
     A fifth local database may be a database that stores information relating to an event. 
     The first main database unit may acquire and store set predetermined data from the first to fifth local databases at predetermined time every day. The first main database unit may also store data from information processing apparatuses other than the first to fifth local databases. For example, data stored by the information processing apparatus for researchers or the like may be stored in the first main database unit. The data moved to the first main database unit may be set as the first art data as initial setting of a disclosure range. Accordingly, there is an advantage that a risk of unintended leakage of information such as opening data moved anew to a museum or opening via the Internet can be reduced. Note that files and folders held in advance before such acquisition may be maintained without changing the setting of the disclosure range set before such acquisition (for example, the first art data, the second art data, and the third art data). In this case, since the preset disclosure range is not changed to the first art data, there is an advantage that a burden of setting the disclosure range again is reduced. 
     3.2. Flow of the System According to the Embodiment 
     Step 1 
     The first art data is stored in the first main database such as the meta database from the first to fifth local databases at first predetermined time every day. 
     Step 2 
     The second art data is stored in the second main database unit such as the museum database from the first main database unit at second predetermined time every day. 
     Step 3 
     The third art data is stored in the third main database unit such as the public database from the first main database unit or the second main database unit at third predetermined time every day. 
     Note that, in the above explanation, the data may not be stored again for a file in which the data is already stored, the file being the same files. In this case, the system in the embodiment may check only the identity of the files and may not perform the storage processing again when it is determined that the files are the same. 
     It may be possible to set, at any time in the flow explained above, as the data in the first main database unit, the first art data, the second art data, the third art data, the first art data and the second art data, the first art data and the third art data, and the first to third art data. 
     4. CONFIGURATION OF THE SYSTEM ACCORDING TO THE EMBODIMENT 
     The system according to the embodiment may be configured from one or a plurality of information processing apparatuses. An information processing apparatus  1410  is explained as an example of such an information processing apparatus. As illustrated in  FIG.  14   , the information processing apparatus may include a bus  1411 , a computing device  1412 , a storage device  1413 , and a communication IF  1416 . The information processing apparatus may include an input device  1414  and a display device  1415 . The information processing apparatus is directly or indirectly connected to a network  19 . 
     The bus may have a function of transmitting information between the computing device, the storage device, the input device, the display device, and/or the communication IF. 
     Examples of the computing device include a processor. The computing device may be a CPU or an MPU. The computing device may include a graphics processing unit or a digital signal processor. In short, the computing device only has to be a device that can execute an instruction of a program. 
     The storage device is a device that records information. The storage device may be either an external memory or an internal memory and may be either a main storage device or an auxiliary storage device. The storage device may be a magnetic disk (a hard disk), an optical disk, a magnetic tape, a semiconductor memory, or the like. The storage device may include a storage device connected via a network or a storage device on the Cloud connected via a network. 
     Note that a register, an L1 cache, an L2 cache, and the like that store information in a position physically close to the computing device may be included in the computing device as a design of a computer architecture or may be included in the storage device. In short, the computing device, the storage device, and the bus only have to be configured to be able to execute information processing in cooperation with one another. 
     The storage device can include a program for executing the system according to the embodiment. The storage device can record, as appropriate, data necessary in executing the system according to the embodiment. The storage device may include a database or the information processing apparatus itself may be the database. 
     In the above explanation, the computing device is executed based on the program provided in the storage device. However, as one of forms in which the bus, the computing device, and the storage device are combined, the information processing relating to the system according to the embodiment may be realized by a programmable logic device that can change a hardware circuit itself or a dedicated circuit in which information processing to be executed is determined. 
     The input device inputs information but may have other functions. The input device may be an input device such as a keyboard, a mouse, a touch panel, or a pen-type pointing device. 
     The display device has a function of displaying information. Examples of the display device include a liquid crystal display, a plasma display, and an organic EL display. In short, the display device only has to be a device that can display information. The display device may include an input device in a part thereof like a touch panel. 
     The network transmits information in conjunction with the communication IF. That is, the network has a function of enabling information in the information processing apparatus to be transmitted to other information processing terminals (not illustrated) via the network. 
     Hardware configuring the information processing apparatus according to the embodiment of the present invention may be a general-purpose electronic computer or a dedicated electronic computer. The hardware may be a workstation, a desktop computer, a laptop computer, a notebook computer, a PDA, a cellular phone, a smartphone, or the like. 
     Although the information processing apparatus is explained as one information processing apparatus in this figure, the information processing apparatus may be configured by a plurality of information processing apparatuses. The plurality of information processing apparatuses may be internally connected or may be externally connected via a network. The information processing apparatus may be a physical entity or may be a virtual entity. For example, the information processing apparatus may be realized by using Cloud computing. In particular, a database or the like may be realized by the Cloud. When the information processing apparatus is configured by the plurality of information processing apparatuses, owners of the information processing apparatuses may be different. A person who operates the information processing apparatus as the system according to the present invention may be different from an owner of the information processing apparatus. For example, when the system according to the embodiment is realized by the Cloud, a part of the system according to the embodiment may be a system relating to an owner and a database or the like in the system according to the embodiment may be the Cloud of a different owner. In this case, the system according to the embodiment includes portions relating to transmission of data to the Cloud of such another owner and reception from the Cloud. However, such a system according to the embodiment may not include the portions included in the Cloud. 
     It goes without saying that the invention examples explained in the embodiments of this application document are not limited to those explained in this application document and can be applied to various examples within the scope of the technical ideas of the invention examples. For example, in the embodiments of this application document, the systems in the embodiments may be configured such that the information presented on the screen of the information processing apparatus can be transmitted to the other information processing apparatus to be displayed on the screen of the other information processing apparatus.
