Yes, it's great to have these issues opened. Not sure if I should comment
here or on the individual threads... I guess I'll start here.

 1. http://www.w3.org/2011/webschema/track/issues/14  "Schema.org
> booleans (True/False) vs RDF 'true/false'"
>

This is the third time this question has come up: Martin raised a related
issue in Aligning GoodRelations and
Schema.org<https://docs.google.com/a/google.com/document/pub?id=1Kx63gW9DBky1j97Jpwl3dU9k0pKPSgCT3EntTVvGjX4>("Action
3"). And in the Activity/Action
proposal<https://docs.google.com/document/d/1VYZ9FmN7Vl2PzzR1kX3KZgfdPK-qUfxR3z12NC3i5V0/edit>we
ask whether
schema.org should host generic instances of selected action types.

Have the schema.org sponsors already designed a general solution for this?
If not, would it make sense to:
  1. Retire any instances masquerading as types (such as schema.org/Trueand
schema.org/InStock),
  2. Define a few generic instances like
http://instance.schema.org/Boolean/true,
http://instance.schema.org/ItemAvailability/inStock, and (if the
Activity/Action proposal is accepted)
http://instance.schema.org/Action/review, and
  3. Specify that when a property of type http://schema.org/Foo has text
value bar, it is shorthand for the value http://instance.schema.org/Foo/bar
?

It may make sense to handle these internal enumerated values in a way
similar to/compatible with ExternalEnumerations.

Since issue 15 just defines datatypes, I think it's orthogonal to the
model. Proposal looks good to me.

Thanks,
