Configure the Source Data Dictionary

The Source Data Dictionary is a tool which helps in visualizing and understanding the potential contents of import files, in terms useful when creating attribute mappings.

The Source Data Dictionary consists of attribute and element metadata. This data is extracted from the import files (the same files from diagram data is imported - refer to Import Diagrams).

This information is made available when configuring the attribute mappings using the XPath Expression Builder dialog (refer to XPath Expression Builder Dialog), in order to reduce the need for a user to understand the source file format and XPath syntax.

The dictionary is populated automatically when diagram data is imported with attribute and element metadata relating to the component classes in the diagram data import files. The dictionary may also be populated manually if required.

During a project life cycle, the Source Data Dictionary may need to be populated or updated manually at the following times:

• On creation of a project, for the purposes of configuring the attribute mappings, prior to the import of diagram files.

• After editing the GTYPE mappings or attribute mappings in such a way that the element types created in the database are affected.

• On configuring attribute mappings for data from a new source system or file format.
