RE: Temporal reference system

s/needs to/should/



This would be more consistent with ISO/IEC conventions for the 'normative language' used to express formal requirements [1]. IETF has a slightly different set [2]. Does W3C have a preferred usage?



Perhaps a sweep of the document to regularize this through all the requirements as stated.

Hello,

Is everyone happy with the way the requirement is phrased now?

"If a temporal reference is used, the description of the temporal reference system (e.g. Unix date, Gregorian Calendar, Japanese Imperial Calendar, Carbon Date, Geological Date) needs to be referenceable online."

If not, we need to create a new issue and relate it to the requirement in the UCR document.

Regards,
Frans

... (moving from requirements into potential solution space) referencing a description of the TRS is what is described in my proposed (backward compatible) amendment to OWL-Time.

Ok, I will rephrase the requirement and add some examples.

+1 also from me.
