AW: Publication types in RDF with RDA

Jakob,

the RDA publication type concludes from  content type, carrier type and media type.
Regarding the RDA cataloguing rules the extent element is meant to specify the "extent" i.e. in extent of text 475 pages. So IMO the LD representation by controlled vocabularies makes no real sense. Because you cannot combine the controlled vocabulary with its associated value.

> http://RDVocab.info/termLIst/extent/1031 = Online Resource
> http://RDVocab.info/termLIst/extent/1031 = Microfiche
> http://RDVocab.info/termLIst/extentNoteMus/1007 = Piano Score

> P.S: "termLIst" looks like a typo, isn't it?
