Dear DAL members,<br>
<br>
Following the proposition made (hum...2 years ago) in the GitHub
Issue <a moz-do-not-send="true"
href="https://github.com/ivoa-std/ADQL/issues/78">#78</a>,<br>
I propose an erratum for ADQL-2.1 in order to add 2 alternative
versions of the<br>
ADQL BNF grammar as auxiliary files:<br>
<br>
- <a moz-do-not-send="true"
href="https://github.com/ivoa-std/ADQL/blob/master/adql.bnf">textual
version</a><br>
(which is actually the source of the grammar include in the ADQL
document)<br>
- <a moz-do-not-send="true"
href="https://github.com/ivoa-std/ADQL/blob/master/adql-bnf.html">HTML
version</a><br>
(with links to easily navigate inside the BNF ; quite useful for
easy and<br>
quick discovery of this grammar)<br>
<br>
Both are only available in GitHub. The idea of this erratum is to
make them<br>
also available through the IVOA Document Repository. Links toward
these files<br>
will then be added inside the Appendix A of the ADQL-2.1 document
showing<br>
the entire BNF.<br>
<br>
I have already written the Erratum in the IVOA's twiki:<br>
<br>
<a moz-do-not-send="true"
href="https://wiki.ivoa.net/twiki/bin/view/IVOA/ADQL-2_1-Err-1"
class="moz-txt-link-freetext">https://wiki.ivoa.net/twiki/bin/view/IVOA/ADQL-2_1-Err-1</a><br>
<br>
I strongly encourage anyone interested into ADQL to take a look on
this.<br>
<br>
If you agree or disagree with this erratum or want to comment or
change<br>
anything, do not hesitate to answer to this email or to communicate
through<br>
the GitHub Issue <a moz-do-not-send="true"
href="https://github.com/ivoa-std/ADQL/issues/78">#78</a>.<br>
<br>
If no disagreement, I plan to present this erratum at the next TCG
meeting<br>
in two weeks.<br>
<br>
Cheers,<br>
Grégory M.
