Dear all,

My take on this, below:

Last week I met with Shadi at W4A, where we discussed a bit this
point. Summarizing my take on this:

1) Indeed, separating both worlds is good to further disseminate EARL
as a reusable vocabulary. RDF has been created from the ground up such
that a Web of triples is not dependent on strict schemas;

2) Strict conformance is something more akin to "traditional"
vocabularies at W3C (i.e., XML-centric, not RDF-centric). This has
leveraged incredible ecosystems of tools around XML languages such as
XSLT, XQuery, XML Schema, XProc.

The only issue I see in these two perspectives is the
non-recommendation status of the EARL Guide: will we still have an
ecosystem of EARL producers and consumers? I don't have a definite
answer for this, although my feeling is that *yes*, there will still
be an ecosystem.

Going onwards with the proposal is an acknowledgement of this issue,
independently of the outcome.
