*Structure of data*

Eachdata 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>

,whereencoding — coding reference designation applied for text file.

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

Forfiles MS DOS: cp866,

Forfiles  Linux: koi8-r.

28

----

version— version of communication protocol (current version 1.0)

file_number — number of thefile 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— date and time of creating of 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> - aclosing tag  xxx. Tag declaration shouldcontain no spaces and tabs. The body between an opening tag  <xxx> and a closing tag  </xxx> is called section xxx.

Thereforeeach file contains a header and a section main. Section main in its turncontains one 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 structured as follows:

<object_1 property=“value”>

</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>

Tomodify a simple attributes included into a complex one all old and newattributes must be entered 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>

</edited_complex_attribute>

</object>

Old attribute value and Newattribute value — attribute value before and after editing. It is used for datamodification (only section update).
