Base URI Management Admin Page
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This admin page displays all graphs that are known to TopBraid from its workspace.
The graphs are grouped by the workspace project they are located in.

Technically, all these graphs form the default **Data Set** that is, for example, used
in the SPARQL ``GRAPH`` keyword.

.. hint::
   TopBraid identifiers graphs via their so-called *Base URIs*.
   For Turtle files, this is usually defined in the first line using a ``# baseURI:...`` comment.
   If this is absent, the system will look for the first ``owl:Ontology`` instance and use
   the URI of that.

The page can be used to detect files with conflicting graph URIs - these will be marked
with a warning icon.

Graphs that declare ``owl:imports`` to missing graphs are also highlighted with an icon.

Both of these problems should be addressed.

.. tip::
  Administrators can also use this page to download and inspect the content of graphs,
  including those stored on databases.
