Hello Olaf, Thank you very much for your feedback and comments in the wiki. This looks very interesting. We are fully aware of the whole provenance issue relating to the linked datasets we are describing. The primary purpose for voiD is to at least help people to find relevant datasets and to find out how they can use this dataset. And our intention is to keep voiD as light as possible. The quesions such as "How has the dataset been created and What was the original source(s)? " themselves could lead to a complete schema, if we want to push for it. :-) I am not aware of any existing vocabularies that we can incorporate. Any idea? Also, if you could also add some comments in the wiki, about "why" you think this provenance information is important for linked datasets and "how" people might use this provenance, it would be fantastic! We are gathering requirements and feedbacks from the community. How the current voiD is to be extended, I guess, would be very much based on the needs from users, such as you:-) With best regards, Jun Olaf Hartig wrote: > Hello > > On Wednesday 11 June 2008 14:07:16 Keith Alexander wrote: > >> Our aim is that existing vocabularies like DC be used where possible, and >> the primer Michael mentioned will hopefully give advice on which existing >> terms are most appropriate to use with the voiD vocabulary.
