+Dirac has to support different Communities with different workflows and requirements. For example:
+- LHCb is a HEP experiment. Stores the metadata and provenance of every produced files in a LHCb-specific database (with an Oracle backend)
+- Belle2 is a HEP experiment. Uses Rucio as data management solution.
+- CTAO is an Astrophysics experiment with radically different requirements (wrt to HEP exp.) on how to process its data
+- WeNMR brings together complementary research teams in the structural biology and life science area
+
+It is sometimes necessary to extend all Dirac(X) components (including Web and Pilot). DiracX aims to provide an easy way to do so.
