SPIN Rules Engine
^^^^^^^^^^^^^^^^^

The SPIN rules engine is a legacy feature that should not be used anymore.
Some internal features of TopBraid, most notably the engine behind the :ref:`Import_ImportSpreadsheetUsingPattern` still use it.

If you're still using SPIN (for anything), please consider migrating to SHACL.
All SPIN features have an equivalent in SHACL.
