Just FYI, the questionnaire to which you refer later in this thread is
specifically not restricted to the shapes WG. (In fact, all of the
respondents to date are outside of the WG.)

claim that having or not having this will make a huge difference in terms
of how business-ready the language is.

with various levels of openness and increasing levels of strictness, after
cleanup and consolidation stages.

others would still need to be hand-coded.

is critical in terms of getting RDF closer to be business-ready. in my work
with XML, JSON, and RDF, one typical criticism of RDF is that it assumes
well-meaning peers, and has little support for scenarios beyond that.
supporting "closed shapes" could be one step in this direction, and i would
like to consider the WG to make this a mandatory feature and provide
fine-grained controls for how open/closed a model should be.
