---++ Towards Vocabularies 2

In preparation to the effort of modernising the Vocabularies in the VO specification, a page was set up to try a comment process for updating the datalink vocabulary, UpdateDatalinkTerms. While this should no longer be used for discussion, the proposals and comments are for now kept for when they will enter a new-style process.

Also, VocabularyTestPage was a now deprecated effort to provide the vocabulary index now on http://www.ivoa.net/rdf.

---++ New UCD List v 1.3

<span style="background-color: transparent;">Elaboration of new UCD keywords for planetary metadata and radio data. This effort is described on the discussion page PlanetaryUCD .<br /></span>

<span style="background-color: transparent;"> </span><span style="background-color: transparent;">This has generated a loop for revision for the UCD list of terms , now in the final step of Recommendation. </span>

<span style="background-color: transparent;">See http://wiki.ivoa.net/twiki/bin/view/IVOA/UCDList2017RFC for the request for comments for http://www.ivoa.net/documents/UCD1+/20170831/index.html. </span><span style="background-color: transparent;"> </span>

---++ Units specification in the IVOA

VOUnits: This specifies how to express unit strings in VO documents, APis, protocols and interfaces.

   * There are no immediate plans for further work on the standard, however there is a small collection of issues and suggestions at VOUnits-1_0-Next

   * Semantics 
      * The [[http://www.euro-vo.org/pub/][EuroVO]] project, [[http://wiki.eurovotech.org/][VOTech]], had a work package [[http://wiki.eurovotech.org/twiki/bin/view/VOTech/ResourceDiscovery][DS5: Intelligent Resource Discovery]] which is focussed on developing astro semantics with the goal of making resource discovery and use more user-oriented. This area of VOTech is led by SebastienDerriere.
      * That page also has [[http://wiki.eurovotech.org/twiki/bin/view/VOTech/ResourceDiscovery#See_also][some useful links]]
