Each data file shall be structured 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 – coding reference designation applied for text file.

For files MS Windows 95/98/NT/2000/XP: windows-1251,

For files MS DOS: cp866,

For files Linux: koi8-r.

version – version of communication protocol (current version 1.0)

file_number – ordinal number of the file transferred (within the company)

keyword – key word applied as an extra identifier of the sending company

company_id – value Sending Company Code - Operator .

, creation_date – data and time of the file in the format YYYY-MM-DDTHH:mm:ss (YYYY – year (4 digits), MM – number of month in a year (2 digits), DD – day of month (2 digits), T – separating symbol – an English letter ‘T’, HH – hour (24-hour format), mm – minutes (2 digits), ss – seconds (2 digits))

Check_sum – reference amount of the file body (data between tags <main> and </<\main>), calculated by algorythm MD5.

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

Therefore each file contains a header and a section main. Section main in its turn contains one or more sections insert, update or delete.

Section insert indicates that the information contained between the tags must be included into database.

<insert oper_date=“oper_date”>

— frame

</insert>

Section update indicates that the information with properties between the tags must be modified in database..

<update oper_date=“oper_date”>

— frame

</update>

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

23

<delete oper_date=“oper_date”>

— frame

</delete>

, where oper_date – effective date of 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 a year (2 digits), DD – day of month (2 digits), T – separating symbol – an English letter ‘T’, HH – hour (24-hour format), mm – minutes (2 digits), ss – seconds (2 digits)

Frame shall be structured as follows:

<object  1 property=“value”>

<simple_attribute>

simple_attribute_value

<complex_attribute>

<simple_attribute>

Simple_attribute_value

</simple_attribute>

. . .

</complex_attribute>

. . .

</complex_attribute>

. . .

<object_2 property=“value”>

. . .

</object_2>

. . .

</object_1>

Object – a section with simple and complex attributes identified by a property. Current version defines an object as a subscriber identified by property subscriber_id and phone identified by property phone_number. There may be no more that one object with the same name and identification property within a parent section.

Property – object identifier.

Complex attribute – a section containing simple and complex properties. There may be no more that one complex object with the same name within a parent section.

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

<object property=“valueе”>

<edited_simple_attribute>

<old>old_attribute_value</old>

<new>new_attribute_value</new>

</edited_simple_attribute>

. . .

</object>

To modify a simple attributes included into a complex one all old and new attributes must be entered with new and old values.

Sample of editing simple attribute within a complex attribute:

<object property=“valueе”>

24

<edited_complex_attribute>

<simple_attribute_1>

<old>old_attribute_value</old>

<new>new_attribute_value</new>

</simple_attribute_1>

<simple_attribute_2>

<old></old>

<new>new_attribute_value</new>

</simple_attribute_2>

<simple_attribute_3>

<old>old_attribute_value</old>

<new></new>

</simple_attribute_3>

. . .

</edited_complex_attribute>

</object>

Old attribute value and New attribute value – attribute value before and after editing. It is used for data modification (only section update).

Deletion and editing of data require indication of values of all essential attributes to ensure univocally of the operation.
