Migration Notes: EDG 8.0 to 8.1
-------------------------------

Support for ``.icg`` files removed
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The EDG workspace will no longer load ``*.icg`` files created in TopBraid Composer.
Renaming such files to ``*.ttl`` will keep the contained graph accessibe under its base URI.
Queries against such graphs may need to be adjusted to explicitly include the imports, e.g., with the ``ui:graphWithImports`` SPARQL function.

Potential changes to GraphQL schemas
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

GraphQL queries against taxonomies may need to be changed if they reference a top-level
field with a name that clashes with imported names. For example in Geo Taxonomy there is now another
queriable class with a local name called Country from Wikidata, which conflicts with g:Country.

For the EDG asset collection types (such as Technical Assets), the GraphQL schemas and search panel now support
querying linked classes (values of sh:class constraints at the public classes).
The additionally reachable classes may theoretically clash with existing classes and thus alter the GraphQL schemas.

Tomcat access log configuration
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Because EDG does not use Tomcat's built-in authentication service, the EDG
username is not included in the default Tomcat access log.
To configure Tomcat so its access log will record the EDG username
see :ref:`tomcat_access_log`.
