Well since it will involve some significant documentation as well as ontology changes, I think a short spec is required. Take a look at two 'extensions' that I already generated for consideration by the SDWIG - - https://w3c.github.io/sdw/time-aggregates/ whose sources are in https://github.com/w3c/sdw/tree/gh-pages/time-aggregates - https://w3c.github.io/sdw/time-entity-relations/ whose sources are in https://github.com/w3c/sdw/tree/gh-pages/time-entity-relations These might be models for you. From a technical perspective, there is a concern not to compromise 'backward compatibility' in the sense that data (individuals, a-box) that follow the current ontology do not become inconsistent or get harmful entailments as a consequence of a new axioms (t-box). Note the approach I took for the 2017 version of OWL-Time was to interpolate super-classes with more generalized definitions above the existing classes that were designed for the Gregorian Calendar. That is where those 'GeneralizedAAA' classes and 'GeneralBBB' datatypes came from. I suspect a similar strategy should be applied to support your use-cases. -----Original Message----- From: Élie Roux <elie.roux@telecom-bretagne.eu> Sent: Monday, 25 May, 2020 04:18 To: public-sdwig@w3.org Subject: Re: Time ontology extension for non-Gregorian calendars > How about proposing specific changes to OWL-Time? I'm very happy to do that yes! What would be the best way to document proposals and submit them? Best, -- Elie
