---++ UCD List 1.3 Proposed Recommendation: Request for Comments

Public discussion page for the UCD List specification version 1.3 Proposed Recommendation

The UCD Standard has defined a vocabulary for classifying physical quantities and labeling dataset descriptions as well as dataset content and has offered a reference list for the values of these semantic labels at http://www.ivoa.net/documents/cover/UCDlist-20070402.html.

It has been revised to include new terms, for statistical quantities, for measurements required by the planetary science and solar physics community, for finer description of metadata.

All new terms have been discussed and checked in their context of use and added to this specification.

New parts of this proposed recommendation compared to the previous version of the UCD List are marked in yellow in this current PR document for easy reading.

Latest version of UCDList can be found at:
   * http://www.ivoa.net/documents/latest/UCDlist.html
The colored version provided [[http://wiki.ivoa.net/internal/IVOA/UCDList2017RFC/PR-UCDlist-1.3-20170831-colored.docx][here]] is easier to spot the added terms and changes .

all changes are in the colored text ( green text, yellow highlighted terms) .
---+++ Reference Interoperable Implementations

UCD are currently used in many catalog tables, and in metadata description as in Obscore, Spectrum DM, etc..

In the VOtable specification, FIELD and PARAM elements have a 'ucd' attribute that should take values into the recommended list of terms provided in this specification.
---+++ Implementations Validators

The CDS UCD builder allows to find an appropriate UCD term from a free text description.

It has been revised to support the new terms of the vocabulary.
