Dear DAL members,<br>
<br>
Following some comments I have received, the Erratum wording has
been<br>
a bit changed. I have also renamed the file for the textual form
into<br>
<font face="monospace">`adql-bnf.txt`</font> (instead of <font
face="monospace">`adql.bnf`</font>).<br>
<br>
Changes I want to apply once the Erratum if/will be approved are
visible in<br>
the following Pull Request: <a moz-do-not-send="true"
href="https://github.com/ivoa-std/ADQL/pull/105">#105</a>.<br>
<br>
Until now, there is no opposition to this Erratum ; only approvals.<br>
If it is still the case, I will proposed this to the TCG.<br>
<br>
Cheers,<br>
Grégory<br>
<br>

<pre wrap="" class="moz-quote-pre">Dear DAL members,
Following the proposition made (hum...2 years ago) in the GitHub Issue #78
<a class="moz-txt-link-rfc2396E" href="https://github.com/ivoa-std/ADQL/issues/78"><https://github.com/ivoa-std/ADQL/issues/78></a>,
I propose an erratum for ADQL-2.1 in order to add 2 alternative versions of
the
ADQL BNF grammar as auxiliary files:
- textual version <a class="moz-txt-link-rfc2396E" href="https://github.com/ivoa-std/ADQL/blob/master/adql.bnf"><https://github.com/ivoa-std/ADQL/blob/master/adql.bnf></a>
(which is actually the source of the grammar include in the ADQL document)
- HTML version <a class="moz-txt-link-rfc2396E" href="https://github.com/ivoa-std/ADQL/blob/master/adql-bnf.html"><https://github.com/ivoa-std/ADQL/blob/master/adql-bnf.html></a>
(with links to easily navigate inside the BNF ; quite useful for easy and
quick discovery of this grammar)
Both are only available in GitHub. The idea of this erratum is to make them
also available through the IVOA Document Repository. Links toward these files
will then be added inside the Appendix A of the ADQL-2.1 document showing
the entire BNF.
I have already written the Erratum in the IVOA's twiki:
<a class="moz-txt-link-freetext" href="https://wiki.ivoa.net/twiki/bin/view/IVOA/ADQL-2_1-Err-1">https://wiki.ivoa.net/twiki/bin/view/IVOA/ADQL-2_1-Err-1</a>
I strongly encourage anyone interested into ADQL to take a look on this.
If you agree or disagree with this erratum or want to comment or change
anything, do not hesitate to answer to this email or to communicate through
the GitHub Issue #78 <a class="moz-txt-link-rfc2396E" href="https://github.com/ivoa-std/ADQL/issues/78"><https://github.com/ivoa-std/ADQL/issues/78></a>.
If no disagreement, I plan to present this erratum at the next TCG meeting
in two weeks.
Cheers,
Grégory M.
