A central home for ontology definition files which define metadata tags used to label CellML files. The labelled CellML files can then be used by both Chaste and the ModellingWebLab by them referring to this central ontology repository.
There are a large number of electrophysiology models already labelled with these annotations at https://github.com/chaste/cellml.
To learn more about possible annotations of CellML files with this ontology please see the Chaste wiki, and to use a drag-and-drop tool for doing the annotation itself please upload a model to the Cardiac Electrophysiology Web Lab.
oxford_metadata.ttl is the human-readable file which should be updated.
After updates, run
python ttl2rdf.py oxford-metadata.ttl oxford-metadata.rdf
to update the RDF file to match, and commit both.
This should now work with python3.
