That's great. (You can tell I have been elsewhere for several years!). I've
now switched to Python for about 4-5 years and wondered if there was
demand.
At heart CML is a structured ontology/knowledge graph and it doesn't matter
whether it's Java or Python (or possibly JS), and whether it's XML or JSON
or YAML.
Or LISP :-)
And is there anything missing? We did surfaces and fragments and
uncertainty - don't know if there are other specialist domains.
