Re: Time ontology extension for non-Gregorian calendars

Dear Peter,

Thanks a lot for your answer!

> There is an attempt at expressing it as an ontology (in RDF/OWL) at https://def.isotc211.org/ontologies/iso19108/. The project that is part of has been criticised; as the RDF/OWL is generated automatically from UML models, it isn't ideal. But it should give you an idea of whether the concepts defined there are useful to you.

Thanks, I'll take a closer look. I take there's no intent to port
these concepts in OWL-Time?

> The UML is available at http://iso.sparxcloud.com/index.php; the document is sold by ISO and (in France) AFNOR; it may be available through your organisation or public library.

Unfortunately I can't access ISO files nor does any of my colleagues
in Academia or my public library; and I don't have a budget for it.
Sending the PDF off-list would result in a lot of gratitude of course!

Best,
