Adding a new , very general question - hope this place suits it :
As a newbie,
I try to position rdf in relation to
I am also interested in understanding various "Constraint standards" based on the context for which they can be used,
and understand the interoperability of various vocabularies or constraint standards in topic maps, including certain rdf vocabularies.
My attempt to understand this relates to a more specific field of interest related to "contract graphs", constraints used to support such approach, and usage of metadata produced through contracts made through social semantic graphs.
I am looking into examples of contexts for which topic map constraints have been developped. Any links welcomed.
