[Crm-sig] homework, Time implementation guideline

Hi Martin,
I think this is fine but if we are defining the labels of the property I would prefer.

P81a	'end of the beginning'
P81b	'start of the end'

P82a	'start of the beginning'
P82b	'end of the end'

Also how does this affect a period which could have differing start and end dates depending on its spatial location? - The Bronze Age in Greece and the UK both have a bronze age but the start and end of the Greek Bronze Age are early than that of the UK Bronze Age.
Or is this not an issue for these properties?

Dear All,

Attached our proposal for a guideline how to implement time in a CRM compatible way in RDF triple stores, following the decision in the last meeting in May.

Please comment.
