The data processing in VertiGIS Integrator takes place through the XML processing.

•Inbound: the incoming data is received via an Inbound Endpoint, converted to an XML format and then transformed via XSLT to UT XML. This UT XML is then converted into create/update/delete operations on the ArcSDE GIS database.

•Outbound: the VertiGIS Integrator detects changes in the GIS database and converts this data into the UT XML format. The UT XML is transformed with XSLT into the target format and then exported via the outbound endpoint to the external system.

UT XML is an XML data structure that can be processed by VertiGIS Integrator and translated into operations on the GIS database (create, read, update, delete).

<ut-xml>

 <!-- 0..N UT Objects -->

 <ut-object>

 ...

 </ut-object>

 <!-- 0..N Features -->

 <feature>

 ...

 </feature>

 <!-- 0..N Table Rows -->SS

 <table-row>

 ...

 </table-row>

</ut-xml>

The following object types are supported in this XML structure:

•ut-object: a complex/basic UT objects (see UT Object XML)

•feature: a single feature in an Esri feature class (see Feature XML)

•table-row: a single row in a registered or un-registered database table (see Table Row XML)

The UT XML format supports a number of Meta Tags to control the data processing and logging.
