Reading Metadata from Special Sources

Similarly to the SQL query metadata mentioned in the previous section, other metadata definitions can be used in the Source tab of the Graph Editor pane.

However, this metadata cannot be edited in Data Shaper Designer.

In addition to the simplest form that defines external (shared) metadata (fileURL="${META_DIR}/metadatafile.fmt") in the source code of the graph, you can use more complicated URLs which also define paths to other external (shared) metadata in the Source tab.

For example:

<Metadata fileURL="zip:(${META_DIR}/delimited.zip)#delimited/employees.fmt"
id="Metadata0"/>

or:

<Metadata fileURL="ftp://guest:guest@localhost:21/employees.fmt"
id="Metadata0"/>

Such expressions can specify the sources from which the external (shared) metadata should be loaded and linked to the graph.
