**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>

,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 communicationprotocol (current version 1.0)**file_number** — number of the filetransferred (within the company)**keyword** — key word applied as anextra identifier of the sending company**company_id** — value **Sending Company Code**—****Operator .

26

----

**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 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**— reference amount of the file body (data betweentags <main> and </<\main>), calculated by algorythm MD5.

Record <xxx> is subsequently denominated anopening tag and </xxx> — a closing tag xxx. Tag declaration should contain no spaces and tabs. The body betweenan opening tag  <xxx> and a closingtag  </xxx> is called section xxx.

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

Section **insert** indicates that the informationcontained between the tags must be included into database.<insert oper_date=**“oper_date”>               **— frame

</insert>

Section **update** indicates that the information withproperties between the tags must be modified in database.<update oper_date=**“oper_date”>**                — frame</update>                Section **delete** indicates that the informationbetween the tags must be deleted from database.<delete oper_date=“**oper_date”>**                **—** frame</delete>, where **oper_date** — effective dateoperation (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-hourformat), mm — minutes (2 digits), ss — seconds (2 digits))**Frame** shall bestructured as follows:<object_1 property=“value”>                <simple_attribute>                simple_attribute_value                </simple_attribute>                ...                <complex_attribute>                             <simple_attribute>                      simple_attribute_value                             </simple_attribute>                             ...                             <complex_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 propertysubscriber_id and phone identified by property phone_number. There may be nomore that one object with the same name and identification property within aparent section.

**Property** — object identifier.

**Complex attribute** — a section containing simple and complexproperties. There may be no more that one complex object with the samename  within a parent section.

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

<objectproperty=“value”>

<edited_simple_attribute>

<old>old_attribute_value</old>

<new>new_attribute_value</new>

</edited_simple_attribute>

**Old attribute value and Newattribute 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 allessential attributes to ensure univocacy of the operation.
