Structure of data

Each data file shall bestructured as follows:

<?xml version=“1.0”encoding=“encoding”?>

<main version=“version”file_number=“file_number” keyword=“keyword” send_from=“company_id”creation_date=“creation_date” check_sum=“check_sum”>

. . .

</main>

,where encoding — codingreference designation applied for text file.

For files MS Windows95/98/NT/2000/XP: windows-1251,

For files MS DOS: cp866,

For files  Linux: koi8-r.

version — version ofcommunication protocol (current version 1.0)

file_number — number ofthe file transferred (within the company)

keyword — key wordapplied as an extra identifier of the sending company

company_id — valueSending Company Code - Operator .

creation_date — date andtime of creating of file in the format YYYY-MM-DDTHH:mm:ss (YYYY — year (4 digits), MM — number of month in ayear (2 digits), DD — day of month (2 digits), T — separating symbol — anEnglish letter ‘T’, HH — hour (24-hour format), mm — minutes (2 digits),ss — seconds (2 digits)

check_sum — referenceamount of the file body (data between tags <main> and</<\main>), calculated by algorythm MD5.

Record <xxx> issubsequently denominated an opening tag and </xxx> - a closing tag  xxx. Tag declaration should contain no spacesand tabs. The body between an opening tag <xxx> and a closing tag </xxx> is called section xxx.

Therefore each filecontains a header and a section main. Section main in its turn containsone or more sections insert, update or delete.

Section insertindicates that the information contained between the tags must be included intodatabase.

<insert oper_date=“oper_date”>

                       — frame

</insert>

Section updateindicates that the information with properties between the tags must bemodified  in database..

<update oper_date=“oper_date”>

                       — frame

</update>

Section deleteindicates that the information between the tags must be deleted from database.

<delete oper_date=“oper_date”>

                       — frame

</delete>

, where oper_date —effective date operation (for example, connection of a telephone number,changes of details) in the format YYYY-MM-DDTHH:mm:ss (YYYY — year (4 digits), MM — number of month in ayear (2 digits), DD — day of month (2 digits), T — separating symbol — anEnglish letter ‘T’, HH — hour (24-hour format), mm — minutes (2 digits),ss — seconds (2 digits))

Frame shall be structuredas follows:

<object_1 property=“value”>

<simple_attribute>

</object_1>

Object — a section withsimple and complex attributes identified by a property. Current version definesan object as a subscriber identified by property subscriber_id and phoneidentified by property phone_number. There may be no more that one object withthe same name and identification property within a parent section.

Property — objectidentifier.

Complex attribute — asection containing simple and complex properties. There may be no more that onecomplex object with the same name  withina parent section.

 Simple attribute — a property (feature) of anobject or complex attribute which value may be set or changed. Simple attributecontains only one value changeable in section Update by tags <old> and <new>. Sample of editing simpleattribute within an object:

<object property=“value”>

<edited_simple_attribute>

<old>old_attribute_value</old>

<new>new_attribute_value</new>

</edited_simple_attribute>

. . .

</object>

To modify a simpleattributes included into a complex one all old and new attributes must beentered with new and old values.

Sample of editing simpleattribute within a complex attribute:

<object property=“value”>

<edited_complex_attribute>

<simple_attribute_1>

<old>old_attribute_value</old>

<new>new_attribute_value</new>

</simple_attribute_1>

</edited_complex_attribute>

</object>

Old attribute value andNew attribute value — attribute value before and after editing. It is used fordata modification (only section update).

Deletion and editing ofdata require indication of values of all essential attributes to ensureunivocacy of the operation.
