Bug ID: 157455
Summary: Better support for embedding XMP metadata in PDF files
Product: LibreOffice
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: enhancement
Priority: medium
Component: Printing and PDF export
Assignee: [email protected]
Reporter: [email protected]
XMP is an ISO standard for representing arbitrary metadata (about a file) as an
RDF graph. It is possible to embed XMP metadata within several different file
formats. PDF v1.4 included support for XMP by describing a standard way in
which XMP metadata may be embedded within PDF files.
Libreoffice supports generating PDF files, but currently seems to lack any way
in which XMP metadata may be included within the resulting PDF files.
The OpenDocument format, itself, supports embedding RDF metadata. One approach
might be to use OpenDocument's support for RDF metadata to store the XMP
metadata: the metadata that should be included in the PDF file. A disadvantage
of this approach is that Libreoffice's support for ODF-embedded RDF metadata is
currently rather poor (see bug #157451).
An alternative approach might be to define the XMP metadata as an external
file, and provide an option (within the PDF export dialogue) to identify the
file. The contents of the file would then be embedded in the PDF file..
Although suboptimal, this approach may be feasible without waiting for bug
#157451 to be resolved.
