Yes. It was in the email and actually very hard to miss! Let me repeat it:


PROPOSAL: Resolve ISSUE-54 by adding the following text to the DCAT introduction:

[[
Data can come in many formats, ranging from spreadsheets over XML and RDF to various speciality formats. DCAT does not make any assumptions about the format of the datasets described in a catalog. Other, complementary vocabularies may be used together with DCAT to provide more detailed format-specific information. For example, properties from the VoID vocabulary [[VoID]] can be used to express various statistics about a DCAT-described dataset if that dataset is in RDF format.
]]


In short, your proposed text says: "VoID is for linked data, DCAT is for catalogs". My proposed text says: "VoID is for data in RDF format, DCAT is neutral with regards to format." Is this acceptable to you? It would avoid John's objection.

Best,
Richard

DCAT is designed to describe any sort of dataset but always within the context of a catalog. This difference in use case is what leads to the differences between the two vocabularies. Publishers are encouraged to publish metadata about their linked data sets using VoID in addition to records that appear in catalogs that use DCAT.
