Re: [dxwg] Related vocabularies mapping [RVM]

@larsgsvensson asked "Can you expand a bit on VoID not being only for RDF?
Given the [definition](https://www.w3.org/TR/void/#dataset) "A dataset is a
set of RDF triples that are published, maintained or aggregated by a single
provider", I'd say that VoID is _only_ about RDF triples..."

Several years ago I had a conversation with one of the authors Richard
Cygniak (it was when I was at CSIRO and I dont have access to the mail
thread any more).

My Use Case was describing datasets that are not _currently_ published as
RDF, but that in an evolving Linked Data environment would ideally be, so
we could kick start the process of providing fine grained semantics about
data and services. I asked whether there is a need for a dataset to be
stored as RDF - and if merely capable of being expressed as RDF was
sufficient. From memory Richard C confirmed that this was a reasonable
interpretation.

Given pretty much all the metadata in Void is optional, there is no problem
with describing TechnicalFeatures that relate to non RDF access methods or
distributions, and leaving out the RDF specific sparqlEndpoint.

Only properties like void:vocabulary, classPartition etc reference IRI
identifiers, and hence a contract around the RDF model that would be
assumed.

(QB helps resolve the shortfall, but void:vocabulary is not actually that
useful anyway as discussed above). so the same issues apply to how mappings
from IRI based identifiers to local identifiers (e.g. column names in a
spreadsheet)  is the one mechanism we need to think about for all these
cases.
