I'm delighted to report that the core ResourceSync Framework Specification is now approved as ANSI/NISO Z39.99-2014. Links to the PDF and HTML versions of the spec, plus tutorial slides, are on the NISOwebsite:
The HTML version of the core specification, and additional specifications in the framework, are hosted on the OAI website:
We'll be working to bring the additional specifications to v1.0 now that the core standard has been approved. As always, comments most welcome on the ResourceSync Google Group [1].
Cheers,
Simeon
