Hi Olaf,
A little correction to your post.
PDF/A-1b does not require the presence of any metadata at all.
No, it does. See ISO 19005-1 Chapter 6.7.2: "The document catalog dictionary
of a conforming file shall contain the Metadata key." It shall contain at
least PDF/A version and conformance level identification information (see
Chapter 6.7.11).
With best regards,
Petras Petkus

Subject: Re: PDFA/1B minimum requirements to pass validation
Hi Augustine,
1. Metadata does not conform to XMP
PDF/A-1b does not require the presence of any metadata at all. Nevertheless,
if metadata is present, it must be present as XMP metadata. By implication:
if the document Info entry for example contains the Title or Author fields,
these fields must also be reflected in matching XMP metadata fields, e.g.
dc:title (where dc is the recommended prefix for metadata fields according
to the Dublin Core metadata standard). For metadata fields that are
expressed using non-standard metadata schemas (e.g. a company specific
metadata schema), an "extension schema description" must also be embedded in
the XMP metadata stream.
To get started I would try to create a PDF with just one metadata field, and
try to get that right. Depending on where you get stuck, please report back…
2. Font not embedded(and text rendering mode not 3)
using the so called standard 14 fonts (without embedding them) is not an
option in PDF/A - even not for very simple ext centric documents like log
files. PDF/A reqires that alll fonts used are embedded (except for fonts
used in invisible text mode / text rendering mode 3). If font embedding is
done right, the fonts do not really need a lot of space.

Hello ,
I am creating a PDFA/1B document using PDFBOX. But the valiation to
PDFA/1B standard is failing and showing below erro messages in
Adobe prob Preflight.
1. Metadata does not conform to XMP
2. Font not embedded(and text rendering mode not 3)
I have two questions
1. what is the minimum meta data set requirement for passing the
validation.
2. Does the usage of base fonts classify for PDFA/1B standard or we need
to embbed it? (The size goes too big as this is done for archiving a log
files)
Can I refere some sample how this meta data and font encoding done?
Appreciate a response.
Regards
Augustine
