OMDoc is a markup format and data model for Open Mathematical Documents. It serves as
semantics-oriented representation format and ontology language for mathematical
knowledge. The formal part of OMDoc has been refined into the
[MMT format](https://uniformal.github.com), and we use the
[MMT System](https://uniformal.github.com) as the reference implementation.

We are currently working on extending MMT to cover the full flexiformal coverage of
OMDoc.
