The Maintenance Process for the set of terms defined as IVOA Unified Content Descriptors is defined in this specification in order to allow the UCD list to evolve following the needs of the astronomical community. It relies on:
   * <span style="background-color: transparent;">the IVOA web pages where to propose new terms to be included, via the ivoa wiki</span>
   * <span style="background-color: transparent;">the review process </span>

I approve the document.

While reading, I did have the same questions and concerns raised by DM and GWS, so I endorse their suggested changes and clarifications.

-- IVOA.TomDonaldson - 2019-03-22

---+++ [[IvoaDAL][Data Access Layer Working Group]]

DAL chair/vice approve the document.

However there are a couple of points we'd like to see clarified or acted upon.

*One (major)* is about the ucd-sci@ivoa.net mailing list. The list seems to be outdated and, while it is asked the submitters to send notification of requests there, this is not reflected in the RFM page.

*A second (medium)* is about the "user" role, described as "any member of the astronomical community" on page 3, but later the doc states any "IVOA member". Given IVOA membership is not so well defined...maybe saying "anyone who has successfully obtained an IVOA TWiki account" would do and would solve also the contact information needed.

Other minor/typographical things are:
   * page 3: Introduction - "...as described in [3]", maybe it's better to explicit the DocStdProc because it's the first time it is referred to. 
      * _changed_ <span style="background-color: transparent;"> MLouys 20190520</span>
   * page 5: could "clarification" inside "amendment" be a separate bullet (or sub-bullet)? 
      * _added_ <span style="background-color: transparent;"> MLouys 20190520</span>
   * page 6: reference to [1] towards the end of the page looks like it should be reference to [3] 
      * _changed_ <span style="background-color: transparent;"> MLouys 20190520</span>
   * page 5: §2.2 - "list is approved as Endorsed Note" -&gt; "list is approved as an Endorsed Note" 
      * _changed_ <span style="background-color: transparent;"> MLouys 20190520</span>
   * global: the document does not have page numbers or any header/footer

---+++ [[IvoaDataModel][Data Model Working Group]]

The document is clear and straight forward.. no problem there.

My only comment is that the implementations (last 2 cycles of RFM) do not follow this procedure, at least with respect to the naming convention for the twiki pages. The spec says "UCDlist-&lt;version_number&gt;-&lt;date&gt;-RFM" while the 2 most recent are "UCDList1dot42017June2018FebRFM" and the current is "RFMforUCD".

Also, can you clarify for me, the &lt;version_number&gt; is the version of the released UCD list. For example, the current REC is 1.3, so the list being built up as RFM to that list should be in a file named "UCDlist-<strong>1_3</strong>-&lt;date&gt;-RFM", and the 1.4 list (above) would be updates to a V1.4 Endorsed Note, which does not seem to exist. Do I have this right?

I will approve the document, but would like to see these cleaned up to make it clearer for following the procedure in the future.
   * Changes: renaming, redirections to keep existing names (the ones above) and alignment of version numbers, removing the date element have been made. Now the 2 topics above figure out as [[UCDList_1-3_RFM]] & [[UCDList_1-4_RFM]]. -- IVOA.MarcoMolinaro - 2019-05-16

The process seems reasonable and straightforward. I only have a couple of document formatting requests:
   * In the PDF version, the title is prefixed with "Microsoft Word - ". Can this be removed? 
      * _Changed_ <span style="background-color: transparent;"> MLouys 20190520</span>
   * In the PDF version, many of the blue underlined words that seem like they should be links but are not. I suggest enabling the links or removing the blue and underscores.

No further comments from GWS.

---+++ [[IvoaResReg][Registry Working Group]]

I approve of this document. I see the scientific advisory board to Semantics functioning as a less meeting-involved arm of the working group, much as registry maintainers in the RofR ecosystem are often indirectly involved in meetings but necessary for our WG's reference implementations and feedback. Hopefully the change to Endorsed Notes also helps speed up process.<br /><br />One grammar comment for the introduction: Singular "they" would be more natural in English here and more inclusive, over "he/she". -- IVOA.TheresaDower - 2018-10-29

<span style="background-color: transparent;"> _Adopted the singular "They" for inclusive notation, thanks MLouys 20190520_ </span>
