Hi
PDF/A files generated using ConTeXt fail validation with veraPDF, and
the reason seems to be that the dc:description metadata is defined with
the wrong type in the embedded XMP extension schema.
https://tex.stackexchange.com/questions/632380/generate-pdf-a-with-context
https://github.com/veraPDF/veraPDF-library/issues/1224
I can reproduce the problem using TeX Live 2021 (MkIV 2021.03.05). The
definition seems to be controlled by this code.

so "dc:description" is not permitted? it is mentioned in
https://www.dublincore.org/specifications/dublin-core/dcmi-terms/#http://purl.org/dc/elements/1.1/description
(btw it never failed before)

The description element is permitted, but the problem seems to be that
its valueType is defined as Text in the embedded schema, while the
metadata element in the PDF has an embedded <rdf:Alt><rdf:li
xml:lang="x-default"> structure.
https://github.com/veraPDF/veraPDF-library/issues/1224#issuecomment-1029932963
(I suppose the reference to "title" in the issue comment should be "description".)
Validating with veraPDF <1.20 does not raise the error. The validation
seems to have changed for redefined types in that version.

I am missing something here... true
<dc:description>FOO</dc:description>
makes a valid pdf 3a with verapdf 1.20.1.
But dc:description is like dc:title, so where we are redefining
dc:description as Text ?

Attach metadata xml for the non-validating and validating example
(extraced with `pdfinfo -meta | xmllint format -`) in the
Github issue.
Here is a reference to the description element. Note that only
description seems to be redefined, not title.

it's not redefined -- it's dropped. And this is ok.
You can also check with
<dc:description>FOO</dc:description>
<dc:title>
<rdf:Alt>
<rdf:li xml:lang="x-default">TITLE</rdf:li>
</rdf:Alt>
</dc:title>
and again it's valid.
But
https://www.iso.org/obp/ui/#iso:std:iso:19005:-1:ed-1:v2:cor:1:v1:en
and
https://www.iso.org/obp/ui/#iso:std:iso:19005:-1:ed-1:v2:cor:2:v1:en:tab:1
suggest that dc:description and dc:title are of the same type,
which is coherent with
XMPSpecificationPart1.pdf
as in
https://github.com/adobe/XMP-Toolkit-SDK/tree/main/docs
I.e. these are correct -- but Subject must agree with dc:description
<dc:description>
<rdf:Alt>
<rdf:li xml:lang="x-default"/>
</rdf:Alt>
</dc:description>
<dc:title>
<rdf:Alt>
<rdf:li xml:lang="x-default">TITLE</rdf:li>
</rdf:Alt>
</dc:title>
At least, this is what I understand.

From what I understand, ConTeXt applies a custom Dublin Core schema
containing just a redefinition of dc:description, which is not coherent
with how dc:description is written by the application.
This patch to lpdf-pda.xml removes the validation error.

Following
https://www.pdfa.org/wp-content/until2016_uploads/2011/08/pdfa_metadata-2b.pdf
