[NTG-context] BibTeX choking on comments in database

Hello list,

I am using BibTeX under ConTeXt to typeset a publication. I noticed
while building the publication ConTeXt raises the following non-fatal
warning:

   ...
   This is BibTeX, Version 0.99d (TeX Live 2023/Debian)
   The top-level auxiliary file: Secret_Sauce.aux
   The style file: cont-au.bst
   Database file #1: ./References.bib
   I was expecting a `{' or a `('---line 2 of file ./References.bib
    : 
    : % See the file Copying for details on copying conditions.
   (Error may have been on previous line)
   I'm skipping whatever remains of this entry
   (There was 1 error message)
   publications    > loading formatting style from 'bibl-apa'
   open source     > level 4, order 13, name
   '/usr/share/texmf/tex/context/bib/mkii/bibl-apa.tex'
   close source    > level 4, order 13, name
   '/usr/share/texmf/tex/context/bib/mkii/bibl-apa.tex'
   ...

All that's present on the first few lines of the References.bib BibTeX
database are comments that begin with the '%' character.

Is there a different character that should be used for BibTeX databases
when used with ConTeXt?

According to the documentation, everything outside of entries is 
considered a comment. Inside of entries, there can’t be comments.

But in this case, is it not warning about text outside of an entry that
should be treated as a comment?

Hard to say without looking at the bib file, but % is not a comment character in bibtex. So, if your file starts with

% @article{key,
% title = {...},
% }

you will get an error from the bib parser.

If you want to comment out an entry, the simplest way is to remove the @. So,

article{key,
  title={...},
}

is a comment (since it is outside the entry).

The first few lines of the file is just a copyright notice, with each
line beginning with %. If that's not an appropriate comment character,
is there any way to put comments in a BibTeX file?

The Context publications reference subsystem reads BibTeX databases but
does not use BibTeX at all. I am not sure what your quoted statement
means exactly.

I see. The first few lines of my BibTeX file just contains a copyright
notice that is commented out with the % character. If that is not a
valid comment character, is there no way to write a comment in the
file?

1) You appear to be using the long-frozen mkii bibliography code.
2) As Aditya wrote, anything outside of a valid entry is ignored.

@comment{
}

is a good construction.

Whenever I wanted to use a citation I'd just write
\footnotecite[something]. But I see now there is this page that
describes a different process for using BibTeX:

   https://wiki.contextgarden.net/Bibliography

I will take a look today and try to incorporate the new best practice
for using the database and its citations. If you have any suggestions I
will try and incorporate them.
