Some of you already noticed, so here's a quick summary.

We've just posted a new version of the schema.org site.

It has two vocabulary changes:

1. addition of http://schema.org/sameAs

Per http://www.w3.org/wiki/WebSchemas/sameAs this adds a property to
Thing that makes it easier to indicate identifying URLs for entities
being described.

2. http://schema.org/citation has been moved up to CreativeWork, from

Details http://www.w3.org/wiki/WebSchemas/CitationPromotion

Thanks to the BibExtend group for suggesting this small but useful improvement.

The site also has some practical improvements:

1. schema.org now has per-property pages.

I'm happy to close this longstanding issue,

Every property in schema.org should now de-reference. For example,
http://schema.org/actor or the links above for
http://schema.org/sameAs and http://schema.org/citation. This is
currently quite basic but should be useful in a number of ways. It
helps with property-centric schemas such as LRMI (e.g.
http://schema.org/learningResourceType ) and provides a foundation for
publishing other useful pieces of information about each property
(source/attribution, mappings, inverses and super-properties etc.).

2. Per-term machine-readable definitions

Our Type, Enumeration and the new Property pages each have basic
embedded RDFa/RDFS schema descriptions. We continue to publish a full
RDFa/RDFS dump of the schema at
http://schema.org/docs/schema_org_rdfa.html and are considering other
improvements (JSON-LD, OWL, change logs / history, etc.).

3. Pages for Enumerations now use '::' instead of '>' to indicate type

http://schema.org/Enumeration has a number of sub-types for areas
where we enumerate a small number of options.  For example,
http://schema.org/BookFormatType is such a type.

http://schema.org/BookFormatType itself has a number of instances,
e.g. http://schema.org/Hardcover

Previously, the presentation of Hardcover was like this:

Thing > Intangible > Enumeration > BookFormatType > Hardcover

We now show this:

Thing > Intangible > Enumeration > BookFormatType :: Hardcover

... to make it slightly clearer that Hardcover is modeled as an instance.

(whether this is a good treatment of book formats is another and more
substantive topic...).

Thanks to all who contributed to this.
