View/Edit Attribute Mappings : XPath Expression Builder Dialog : Building Expressions : Source Dictionary Pane
Source Dictionary Pane
The Source Data Dictionary is a tool which helps in visualising and understanding the potential contents of import files, in terms useful when creating attribute mappings.
The Source Dictionary pane contains a tree-view that lists all the relevant Source Data Dictionary information for the current attribute mapping or attribute mapping group.
The database element types are all listed against the top node of the tree view. This node can be expanded to display the import file standards, for example XMpLant, of the imported data.
Each import file standard node can be expanded to list the attributes which are common to all of the selected database element types and that are of that import file standard.
If the required attributes are not displayed, or no attributes are displayed, the dictionary must be populated by extracting attribute data from diagram import files. Refer to Access the Source Data Dictionary.
Each of the attribute nodes can be expanded to display the following nodes, which display attribute metadata.
Src - XPath to the source of the attribute. This is the text that will be added to the expression if the attribute is added to it.
SrcUnits - XPath to the units of the attribute (if applicable).
Type - Storage type for the attribute (e.g. string, integer).
Has Content - Yes/No, indicates whether or not the attribute has been observed with content at any time.
Min Cardinality - Displays the minimum observed cardinality of the attribute.
Max Cardinality - Displays the maximum observed cardinality of the attribute.
Of the above, Src and SrcUnits can be added to an expression. The other data is presented for information only.
To add an attribute or attribute data to an expression, either drag and drop the data item from the Source Dictionary pane into the Expression pane, or double-click on the data item.
If dragged and dropped, the data item is added to the expression where it is “dropped”. If double-clicked the data item is added to the expression at the point that the cursor is currently located in the Expression pane.
