<br>
Sorry to come so late with this request, with TAP v1.1 already in its RFC phase.<br>
<br>
Would it be possible to add a new optional column to the TAP_SCHEMA.tables<br>
where the data provider could store the URL pointing to some documentation<br>
(e.g. a release description, an ADS article, a DOI landing page, etc.)<br>
about that table?<br>
<br>
Thanks and sorry again,<br>
Alberto<br>
