## Title
Providing compartmentalized security in product reviews

## Abstract

A mechanism is provided for providing compartmentalized security in product reviews. A central authoritative state module within a compartmentalized security mechanism identifies a clearance level associated with a user that has been authenticated. Responsive to the clearance level of the user being sufficient to access the information, the central authoritative state module determines whether the information requires a simulation to be executed. Responsive to the information failing to require execution of a simulation, a coordination module in the compartmentalized security mechanism retrieves the information. A display and input interaction module on a client system then displays the information in accordance with the clearance level of the user thereby forming displayed information. Displaying the information in accordance with the clearance level of the user comprises displaying in detail only portions of the information of the product that the user has access to.

## Background
BACKGROUND
The present application relates generally to an improved data processing apparatus and method and more specifically to mechanisms for providing compartmentalized security in product reviews.
Product lifecycle management (PLM) is the process of managing an entire lifecycle of a product from its conception, through design and manufacture, to service and disposal. PLM integrates people, data, processes and business systems and provides a product information backbone for companies and their extended enterprise. Product lifecycle management includes managing descriptions and properties of a product through its development and useful life, mainly from a business/engineering point of view.
Product lifecycle management is one of the four cornerstones of a corporation's information technology structure. All companies need to manage communications and information with their customers (CRM—Customer Relationship Management), their suppliers (SCM—Supply Chain Management), their resources within the enterprise (ERP—Enterprise Resource Planning) and their planning (SDLC—Systems Development Life Cycle). In addition, manufacturing engineering companies must also develop, describe, manage, and communicate information about their products.
Virtual design reviews or PLM reviews allow multiple users to view and interact with 3D models as part of a product lifecycle design review. Virtual design reviews are usually centered around design and engineering reviews, for example a distributed group of engineers reviewing a jet engine in 3D. Currently, security on product lifecycle management assets are defined for the entire asset. Generally, access to a PLM asset is controlled by typical file access control means, such that if a user has access to the file, then the user has access to everything associated with the asset. With PLM design reviews becoming more collaborative and leveraging virtual world technologies, different types of users will simultaneously participate in a PLM design review.
SUMMARY
In one illustrative embodiment, a method, in a data processing system, is provided for providing compartmentalized security in product reviews. The illustrative embodiment identifies a clearance level associated with a user that has been authenticated. The illustrative embodiment determines whether the clearance level of the user is sufficient to access the information associated with a product.

DETAILED DESCRIPTION
The illustrative embodiments provide a mechanism for different types of users to simultaneously participate in a review, but, for security reasons, only allowing a user to view data based on the role that user plays in the product. To provide for compartmentalized security in product or design reviews including models and simulation results, the illustrative embodiment provides mechanisms that allows real-time collaboration while ensuring data security. Since the mechanisms of the illustrative embodiment allows access to and transmits only those compartments that an end user is authorized to access, the illustrative embodiments provide very strong content protection. Multiple users with different levels of security clearance may interact in real time on an object instance. The mechanisms of the illustrative embodiments provides access to alternative levels of detail and protected information depending on user privilege or clearance, while guaranteeing a consistent shared experience in a spatial environment. This allows, for example, manufacturers to cooperate across organizational boundaries with suppliers. Further, the mechanism of the illustrative embodiments not only allow a display of the 3D asset but the cooperative manipulation of the asset by a participant according to policy settings associated with the users privilege or clearance.
FIG. 1 depicts a block diagram of a compartmentalized simulation and object description mechanism in accordance with an illustrative embodiment. Compartmentalized simulation and object description mechanism 102, which may also be referred to as a compartmentalized security mechanism, within data processing system 100 comprises central authoritative state module 104 that communicates with client systems 150a-150n to display one or more of models 152a-152n, text 154a-154n, and simulation results 156a-156n, and/or run compartmentalized simulations 158a-158n using compartmentalized object descriptions 160a-160n. For each request submitted by a user of client systems 150a-150n, central authoritative state module 104 authenticates the user using known authentication mechanisms and then identifies the user's clearance level using user clearances database 110.
Once the user is authenticated and the user's clearance level is identified, central authoritative state module 104 determines one or more models, text, or simulation results associated with the request that is stored in data sources 112 associated with a specific product lifecycle management (PLM) review. If the request is to perform a simulation, central authoritative state module 104 may initiate a simulation associated with a specific PLM review. Central authoritative state module 104 determines whether the user has an appropriate clearance level to access the one or more models, text, or simulation results, or request that the simulations be executed. If the user has the appropriate clearance level and has requested access to one or more models, text, or simulation results stored in data sources 112 associated with a specific product lifecycle management (PLM) review, central authoritative state module 104 initiates simulation coordination module 106 that may retrieve the requested one or more models, text, or simulation results stored in data sources 112 associated with a specific PLM review the user has selected and is permitted to access using the user's clearance level.
Using client system 150a as an example as a requesting one of client systems 150a-150n, once simulation coordination module 106 has retrieved the one or more models, text, or simulation results associated with a specific PLM review that the user has selected and is permitted to access using the user's clearance level, central authoritative state module 104 sends the identified one or more models, text, or simulation results, to client system 150a via network 180 where the information is stored as models 152a, text 154a, and/or simulation results 156a on local storage 162a. Once the information is on client system 150a, display and input interaction module 164a may display the requested information in either two dimensions or three dimensions based upon the credential level of the user. That is, for example, if the user has gold credentials, then display and input interaction module 164a may display the product as fully detailed. As an alternative example, if the user has bronze credentials, then display and input interaction module 164a may display objects with which the user has access as emphasized objects, while the remaining portions of the product is displayed in a deemphasized manner. The deemphasized manner may include showing a generic model of the product, a grayed out semblance of the product, not showing specific portions of the product, or the like.
If the user requests the execution of a simulation associated with a specific PLM review, compartmentalized simulation and object description mechanism 102 may determine whether the user has requested that the simulation be performed by compartmentalized simulation and object description mechanism 102 or locally by the requesting one of client systems 150a-150n. The only difference between compartmentalized simulation and object description mechanism 102 performing the simulation or the requesting one of client systems 150a-150n performing the simulation is whether simulation runtime module 118 on compartmentalized simulation and object description mechanism 102 executes the simulation or the associated one of local simulation runtime module 166a-166n executes the simulation. If the simulation is to be executed by either simulation runtime module 118 or by the associated one of local simulation runtime module 166a-166n, central authoritative state module 104 initiates compartment coordination module 108 that may then identify one or more compartments stored in data sources 112 that are associated with the selected simulation.
Once compartment coordination module 108 identifies one or more compartments stored in data sources 112 associated with the selected simulation, compartment coordination module 108 may interrogate aggregated asset descriptions 114 to identify all objects associated with each of the one or more compartments. Aggregated asset descriptions 114 identify an object, a collection of objects, a complete scene, or the like, for each compartment in data sources 112. A complete scene may refer to a grouping of objects that are related. For example, if a jet engine is being reviewed, the ‘complete scene’ may describe all of the parts that make up the airplane, not just the engine. Aggregated asset descriptions 114 may also comprise spatial description, associated textures and other artwork, metadata, or the like, associated with each object. Aggregated asset descriptions 114 may also identify policy information for each object that dictates a level of access for different types of users based on the user's credentials. That is, the policy information has a structure such that some objects associated with the compartment may be identified/displayed in general terms while other objects (objects that are accessible by the user) will be identified/displayed in specific detail. Thus, the policy information allows finely differentiated access/views into the data. The policy information also includes authorization for updates to objects that are accessible by the user.
Optionally, central authoritative state module 104 may initiate alternative compartment generator 116 in order to identify alternative compartment descriptions that may be provided to the user. For example, alternative compartment generator 116 may provide a high definition geometry definition of objects for users that have gold credentials, whereas alternative compartment generator 116 may provide only a low geometric definition of objects to users that have bronze credentials. As another example, alternative compartment generator 116 may provide product texture designs for users that have gold credentials, whereas alternative compartment generator 116 may provide prototype camouflage texture for users with silver credentials. While the previous examples identify users credential using gold, silver, and bronze identification, the illustrative embodiments recognize that any identification may be used to identify the level of credential a user has, such as associating a number from 1 to n, using identifiers such as high, medium high, medium, medium low, or low, or the like. In cases where compartments may be empty with relation to the level of credentials the user has, alternative compartment generator 116 may return an “access unauthorized” signal to a user that has bronze credentials while a user that has gold credentials may receive associated resource cost.
Using client system 150a as an example as a requesting one of client systems 150a-150n, once compartment coordination module 108 and/or alternative compartment generator 116 identify and/or generate all of the objects associated with the identified compartments, central authoritative state module 104 may either initiate execution of the simulation by simulation runtime module 118 or send the identified simulation request, compartments, identified objects, generated objects, or the like, to client system 150a via network 180 where the information is stored as compartmentalized simulation 158a and/or compartmentalized object descriptions 160a on local storage 162a. If the simulation is executed by compartmentalized simulation and object description mechanism 102, simulation dispatcher 120 forwards the simulation request to simulation runtime module 118. Simulation runtime module 118 may then execute the requested simulation using the identified simulation, compartments, identified objects, generated objects, or the like. As simulation runtime module 118 executes the simulation, each identified object associated with the various compartments registers with simulation dispatcher 120. Simulation runtime module 118 executes the simulation of the product in accordance with the credentials of the user. That is, for example, if the user has gold credentials, then simulation runtime module 118 may display the product as fully detailed, with full object identification provided by simulation dispatcher 120. As an alternative example, if the user has bronze credentials, then simulation runtime module 118 may display objects with which the user has access as emphasized objects, while the remaining portions of the product is displayed in a deemphasized manner. Once simulation runtime module 118 completes the execution of the simulation, central authoritative state module 104 may send the simulation results to client system 150a to be stored as simulation results 156a in local storage 162a. 
If the simulation is executed locally, local simulation dispatcher 168a forwards the request to local simulation runtime module 166a. Upon request, local simulation runtime module 166a may execute compartmentalized simulation 158a. In one implementation, local simulation runtime module 166a is an operating system and compartmentalized simulation 158a is an executable. As local simulation runtime module 166a executes compartmentalized simulation 158a, each object in compartmentalized object descriptions 160a associated with the various compartments of compartmentalized simulation 158a registers with local simulation dispatcher 168a. Local simulation runtime module 166a executes the simulation of the product in accordance with the credentials of the user. That is, for example, if the user has gold credentials, then local simulation runtime module 166a may display the product as fully detailed, with full object identification provided by local simulation dispatcher 168a. As an alternative example, if the user has bronze credentials, then local simulation runtime module 166a may display objects with which the user has access as emphasized objects, while the remaining portions of the product is displayed in a deemphasized manner. Once local simulation runtime module 166a completes the execution of the simulation, local simulation runtime module may store the simulation results as simulation results 156a in local storage 162a. 
Another feature of local simulation runtime modules 166a-166n is to replay the results of a simulation without actually performing the actual simulation. Simulation results 156a-156n may be in the form of a bunch of numbers or may include other result types like animating objects through a sequence of steps. For example, a car crash simulation may show places where the metal stresses and bends and how the pieces of the car move as the crash happens. Another example, may be where an object colored with a color gradient shows a specific color to indicate stress points in the design. Local simulation runtime modules 166a-166n may use the simulation results 156a-156n to replay the simulation and show various changes.
In keeping with the examples above, once display and input interaction module 164a identifies that the requested models, text, or simulation results have been received, display and input interaction module 164a displays the product to the user as a three-dimensional displaying of the product. With the product displayed, the user may now request detailed information associated with displayed objects. Upon request, local simulation dispatcher 168a retrieves specific object information stored in local storage 162a and display and input interaction module 164a displays the object information in either a pop-up display box, as another window on the display, as part of the displayed environment, or the like, such that the user may easily identify the associated metadata. If the user requests access to object information to unregistered compartment/object information, such as objects or compartments to which the user does not have a proper level of credentials, local simulation dispatcher 168a transmits the request to central authoritative state module 104. Central authoritative state module 104 may then forward the request to a credentials administrator for authorization and, depending on the response of the administrator, central authoritative state module 104 may either grant or deny access to the compartment/object information. If the request is granted, central authoritative state module 104 may request compartment coordination module 108 and/or alternative compartment generator 116 to retrieve the compartment/object information prior to sending the acknowledgement back to local simulation dispatcher 168a so that the retrieved information is sent along with the acknowledgement. Alternatively, central authoritative state module 104 may send the acknowledgement directly to local simulation dispatcher 168a and local simulation dispatcher 168a will have to request that the compartment/object information be retrieved as part of another request.
As the user interacts via display and input interaction module 164a, the user may request changes to objects with which the user has a level of credentials to change. In a collaborative session, where two or more users are reviewing the same product simulation via display and input interaction module 164a-164n, as the first user makes a change, local simulation dispatcher 168a transmits the changes to central authoritative state module 104. Central authoritative state module 104 initiates compartment coordination module 108 to update aggregated asset descriptions 114. Once aggregated asset descriptions 114 have been updated, central authoritative state module 104 may then transmit the changes to local storages 162b-162n. Display and input interaction module 162b-162n may then use the updated changes to redisplay the product to the user as a three-dimensional displaying of the product. Thereby real time shared collaboration on the same object is made possible.
Central authoritative state module 104 ensures that changes to compartments are consistent with other compartments. For example, a user with bronze credentials may only see a low resolution texture and may attempt to replace it with another texture. Since the user with bronze credentials may not know that high-resolution textures are deployed but not accessible to him, central authoritative state module 104 may notify the user that such an update is not possible due to high-resolution textures already existing.
Thus, the illustrative embodiment provides mechanisms that allow real-time collaboration while ensuring data security. Since the mechanisms of the illustrative embodiment allows access to and transmits only those compartments that an end user is authorized to access, the illustrative embodiments provide very strong content protection. Multiple users with different levels of security clearance may interact in real time on an object instance. The mechanisms of the illustrative embodiments provides access to alternative levels of detail and protected information depending on user privilege or clearance, while guaranteeing a consistent shared experience in a spatial environment.
FIGS. 2A-2B depict one example of a product being managed by a product lifecycle management system in accordance with an illustrative embodiment. In FIG. 2A, circuit board 200 is depicted along with various components, such as diode 202, transistor 204, large resistor 206, relay 208, capacitor 210, integrated chip 212, and small resistor 214. As part of a collaborative PLM review session circuit board 200, a user having gold credentials may have access to view all of the components of circuit board 200 as well as specific details associated with the components. However, even with a user having gold credentials, a user may be limited by which details they have access to. For example, a project manager may have gold credentials and have access to timeline details as to when each component will order, ship, arrive, or the like, so that assembly of the circuit board 200 may be scheduled. In another example, a financial officer may have gold credentials and have access to cost information associated with each component of circuit board 200. As another example, an engineer responsible for the entire function of circuit board 200 and having gold credentials may have access to component details as well as functioning properties of each component on circuit board 200 as well as the entire operation performed by circuit board 200.
However, in order to have a collaborative sessions with vendors of the various components on circuit board 200, a vendor having bronze credentials may have limited access to components on circuit board 200. FIG. 2B depicts one example where the manufacturer of large resistors, such as large resistor 206, is provided with a display emphasizing only the large resistors. While the vendor may see a deemphasized view of circuit board 200, the vendor has access to view details associated with the large resistors, such as large resistor 206. The deemphasized view may include showing a generic model of the product, a grayed out semblance of the product, not showing specific portions of the product, not showing any other portion of the product, or the like. Pop-up display 220 depicts an example of details that the vendor of large resistor 206 may see in association with large resistor 206. The details may include, but are not limited to, resistance in ohms, power in watts, tolerance, packaging, technology, size, packing method, mounting feature, date needed, expected ship date, cost, or the like. While this example provides details of what the vendor of large resistor 206 may see, one of ordinary skill in the art would realize that other vendors of other products will see details associated with their specific component(s) with which they are responsible.
FIGS. 3A-3B depict another example of a product being managed by a product lifecycle management system in accordance with an illustrative embodiment. In FIG. 3A, crank shaft assembly 300 is depicted along with various components, such as piston 302, piston snap ring 304, piston pin 306, connecting rod 308, cap attaching bolts 310, and crank shaft 312. As part of a collaborative PLM review session of crank shaft assembly 300, a user have gold credentials may have access to view all of the components of crank shaft assembly 300 as well as specific details associated with the components. However even with a user having gold credentials, a user may be limited by which details they have access to. For example, a project manager may have gold credentials and have access to timeline details as to when each component will order, ship, arrive, or the like, so that assembly of the crank shaft assembly 300 may be scheduled. In another example, a financial officer may have gold credentials and have access to cost information associated with each component of crank shaft assembly 300. As another example, an engineer responsible for the entire function of crank shaft assembly 300 and having gold credentials may have access to component details as well as functioning properties of each component on crank shaft assembly 300 as well as the entire operation performed by crank shaft assembly 300.
However, in order to have a collaborative sessions with vendors of the various components on crank shaft assembly 300, a vendor having bronze credentials may have limited access to components on crank shaft assembly 300. FIG. 3B depicts one example where the manufacturer of the pistons, piston snap rings, and piston pin, such as piston 302, piston snap ring 304, and piston pin 306, is provided with a display emphasizing only the pistons, piston snap rings, and piston pins. While the vendor may see a deemphasized view of crank shaft assembly 300, the vendor has access to view details associated with the pistons, piston snap rings, and piston pin, such as piston 302, piston snap ring 304, and piston pin 306. Pop-up display 320 depicts an example of details that the vendor of piston 302 may see in association with piston 302. The details may include, but are not limited to, bore, head type, cylinder height, stroke, compression height, compression ratio, rod length, piston/pin weight, date needed, expected ship date, cost, or the like. While this example provides details of what the vendor of piston 302 may see, one of ordinary skill in the art would realize that other vendors of other products will see details associated with their specific component(s) with which they are responsible.

Referring now to FIGS. 4-6, these figures provide flowcharts outlining example operations of a compartmentalized simulation and object description mechanism in accordance with an illustrative embodiment. FIGS. 4A-4B provide a flowchart outlining example operations performed by compartmentalized simulation and object description mechanism in processing an initial request from a user in accordance with an illustrative embodiment. As the operation begins, the compartmentalized simulation and object description mechanism receives a request submitted by a user of a client system (step 402). A central authoritative state module within the compartmentalized simulation and object description mechanism authenticates the user (step 404). The central authoritative state module then determines if the user has been authenticated (step 406). If at step 406 the central authoritative state module determines that the user has not been authorized, then the central authoritative state module sends an error back to the client system where the error is presented to the user (step 408) with the operation returning to step 402 thereafter. If at step 406 the central authoritative state module determines that the user is authorized, then the central authoritative state module identifies the user's clearance level (step 410).
Once the user is authenticated and the user's clearance level is identified, the central authoritative state module determines whether the user has an appropriate clearance level to access the one or more models, text, or simulation results, or to request that a simulation be executed (step 412). If at step 412 the central authoritative state module determines that the user has insufficient clearance, then the operation returns to step 402. If at step 412 the central authoritative state module determines that the user has the appropriate clearance level, then a coordination module in the compartmentalized simulation and object description mechanism determines if the request is for a simulation to be executed (step 414).
If at step 414 the coordination module determines that the request is not for a simulation to be run but rather access to one or more requested models, text, or simulation results, the coordination module identifies and retrieves the requested one or more models, text, or simulation results from a storage associated with the compartmentalized simulation and object description mechanism (step 416). The central authoritative state module then sends the identified one or more models, text, or simulation results to the requesting client system where the information is stored as either models, text, and/or simulation results on a local storage (step 418). Once the information is stored in local storage on the client system, a display and input interaction module on the client system may display the requested information in accordance with the clearance level of the user (step 420), with the operation ending thereafter.
If at step 414 the coordination module determines that the request is for a simulation, compartment coordination module within the compartmentalized simulation and object description mechanism identifies one or more compartments associated with the selected simulation stored in the storage (step 422). Once the compartment coordination module identifies one or more compartments associated with the selected simulation, a compartment selector within the compartmentalized simulation and object description mechanism may interrogate a set of aggregated asset descriptions to identify all objects associated with each of the one or more compartments (step 424). The set of aggregated asset descriptions may identify an object, a collection of objects, a complete scene, or the like, for each compartment. The set of aggregated asset descriptions may also comprise spatial description, associated textures and other artwork, metadata, or the like, associated with each object. The set of aggregated asset descriptions may also identify policy information for each object that dictates a level of access for different types of users based on the user's credentials.
The central authoritative state module may then determine whether one or more alternate compartment descriptions are required based on the clearance level of the user (step 426). If at step 426 the central authoritative state module determines that one or more alternate compartment descriptions is required, then an alternative compartment generator within compartmentalized simulation and object description mechanism may identify and generate alternative compartment descriptions (step 428). From step 428 or if at step 426 the central authoritative state module determines that one or more alternate compartment descriptions is not required, the central authoritative state module determines whether the user has requested that the simulation be performed locally by the client system (step 430).
If at step 430 the simulation is not to be run locally but by the compartmentalized simulation and object description mechanism, then a simulation dispatcher within the compartmentalized simulation and object description mechanism registers the compartments, identified objects, generated objects, or the like, associated with the simulation (step 432). A simulation runtime module within the compartmentalized simulation and object description mechanism then executes the requested simulation using the compartments, identified objects, generated objects, or the like, registered with the simulation dispatcher (step 434). Once the simulation runtime module completes the execution of the simulation, then central authoritative state module sends the simulation results to then client system to be stored as simulation results in the local storage of the client system (step 436). Once the information is stored in local storage on the client system, the display and input interaction module on the client system displays the product in accordance with the clearance level of the user (step 438), with the operation ending thereafter.
If at step 430 the simulation is to be run locally on the client system, then the central authoritative state module sends the simulation request, compartments, identified objects, generated objects, or the like, associated with the simulation to the client system where the compartments, identified objects, generated objects, or the like, associated with the simulation are stored in local storage (step 440). A local simulation dispatcher within the client system then registers the compartments, identified objects, generated objects, or the like, associated with the simulation (step 442). A local simulation runtime module within the client system then executes the requested simulation using the compartments, identified objects, generated objects, or the like, registered with the simulation dispatcher (step 444). Once the local simulation runtime module completes the execution of the simulation and stores the results in the local storage (step 446), the display and input interaction module displays the product in accordance with the clearance level of the user (step 448), with the operation ending thereafter.
FIG. 5 provides a flowchart outlining example operations performed by compartmentalized simulation and object description mechanism in processing a detailed description request from a user in accordance with an illustrative embodiment. As the operation begins, the local simulation dispatcher receives a request for detailed information associated with an object and/or a compartment (step 502). The local simulation dispatcher then determines if the detailed information resides within the local storage of the client system (step 504). If at step 504 the local simulation module determines that the information is within the local storage indicating that the user has the clearance to view the detailed information, then the local simulation module retrieves the detailed information (step 506) and the display and input interaction module displays the detailed information in either a pop-up display box, as another window on the display, or the like, such that the user may easily identify the associated metadata (step 508), with the operation ending thereafter.
If at step 504 the local simulation module determines that the information fails to be within the local storage, the local simulation dispatcher transmits the request to the central authoritative state module (step 510). The central authoritative state module then forwards the request to a credentials administrator for authorization (step 512). The central authoritative state module then determines whether a response is received granting access or denying access to the detailed information (step 514). If at step 514 a response is received denying access, then the central authoritative state module sends a deny signal to the client system where the display and input interaction module displays a message indicating that access to the detailed information is denied (step 516), with the operation ending thereafter.
If at step 514 a response is received granting access, the central authoritative state module requests the compartment coordination module and/or the alternative compartment generator to retrieve the compartment/object detailed information (step 518). The central authoritative state module then sends the detailed information back to the client system where the display and input interaction module displays the detailed information (step 520) with the operation ending thereafter.
FIG. 6 provides a flowchart outlining example operations performed by compartmentalized simulation and object description mechanism in processing a change to a description of an object or compartment from a user in accordance with an illustrative embodiment. The operation performed in FIG. 6 may be performed during a single access to a product lifecycle management (PLM) review or as part of a collaborative access during a PLM review. As the operation begins, the local simulation module receives a request to change a description of an object or a compartment (step 602). The local simulation module sends the requested change to the central authoritative state module (step 604). The central authoritative state module determines if the user has clearance to update the description of the object or the compartment (step 606). If at step 606 the central authoritative state module determines that the user fails to have sufficient clearance, the central authoritative state module forwards the request to a credentials administrator for authorization (step 608). The central authoritative state module then determines whether a response is received granting access or denying access to the detailed information (step 610). If at step 610 a response is received denying access, then the central authoritative state module sends a deny signal to the client system where the display and input interaction module displays a message indicating that the change to the description of an object or a compartment is denied (step 612), with the operation ending thereafter.
If at step 610 a response is received granting access to change the description of an object or a compartment or if at step 606 the central authoritative state module determines that the user has sufficient clearance, the central authoritative state module initiates the compartment coordination module to update aggregated asset descriptions (step 614). Once the compartment coordination module updates the aggregated asset descriptions, the central authoritative state module may then transmit the changes to the local storage of the client system if the session is a single access to a PLM review or to the local storages of multiple client systems of the session is part of a collaborative PLM review (step 616). The display and input interaction module(s) then use the updated changes to redisplay the product to the user(s) as a three-dimensional displaying of the product (step 618), with the operation ending thereafter.
