Is there a URL for that?

Interesting.

Good suggestion thanks. We will improve the SDMX references before the 
next release of the working draft. I have created a working group action 
item (ACTION-63) to track this.

Because as far as I'm aware there are none that are normatively 
referencable.

The only RDF versions of COG that I know of are the ones at:
   http://purl.org/linked-data/sdmx/2009/concept#
   http://purl.org/linked-data/sdmx/2009/dimension#
   http://purl.org/linked-data/sdmx/2009/attribute#
   http://purl.org/linked-data/sdmx/2009/measure#
   http://purl.org/linked-data/sdmx/2009/metadata#
   http://purl.org/linked-data/sdmx/2009/code#
   http://purl.org/linked-data/sdmx/2009/subject#

Whilst we made every effort to ensure those were faithful encodings of 
COG 2009 they have not been formally reviewed or approved by either 
sdmx.org or this working group [*] so I don't think they can be used 
normatively in the spec.

Does you know if these are the RDF versions being referred to in the 
above quote?


Please let us know if you are satisfied with this response.

Dave

claiming any formal official standing for them.
