Hi, I'm working on a project where I have some XML that has @xlink:role="person" @xlink:role="corporateBody" or @xlink:role="family" on a certain element. I just learned that @xlink:role is supposed to be a URL [1] So I took a look at http://id.loc.gov/ and I could not find anything that looked like it would work for this. Then I found http://vocab.org/ which lead me to http://vocab.org/frbr/ where I found FRBR has http://purl.org/vocab/frbr/core#CorporateBody and http://purl.org/vocab/frbr/core#Person But is has nothing like the "Family" from EAC-CPF. I thought this might be a good place to check if anyone knows of a pre-existing vocabulary that can handle this case? Would it be bad just to make up "http://purl.org/vocab/frbr/core#Family" and use that? Could we use FRBR for CorporateBody and Person and get Family from somewhere else? Thanks for any ideas or suggestions -- Brian [1] http://www.w3.org/TR/xlink/#link-semantics The value of the role or arcrole attribute must be a URI reference as defined in [IETF RFC 2396], except that if the URI scheme used is allowed to have absolute and relative forms, the URI portion must be absolute. The URI reference identifies some resource that describes the intended property. When no value is supplied, no particular role value is to be inferred. Disallowed URI reference characters in these attribute values must be specially encoded as described in 5.4 Locator Attribute (href).
