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.
