Hi Catharine,

I'm working with the OGC and taking up migrating some of Simon's work
publishing vocabularies as Linked Data into OGC infrastructure. This is
driven partly by the GEOSS requirements for standards coordination, and
hence there is a wider conversation to be had first amongst OGC membership
and then GEOSS around the desirability of best practices in Linked Data
behind vocabularies.

Likewise I would like to use your email as evidence of demand - and if you
have any other citable published documents that address this issue would
love to have these to read and reference.

Regards
Rob Atkinson
