URL: https://github.com/apache/tika/pull/2266
> Improve xmp metadata key precision for PDFs
> -------------------------------------------
>
> Key: TIKA-4449
> URL: https://issues.apache.org/jira/browse/TIKA-4449
> Project: Tika
> Issue Type: Task
> Reporter: Tim Allison
> Priority: Major
>
> PDFs (and other file formats) may have conflicting information within them
> about, for example, the "title" field or the "author" field.
> Tika's parsers typically pick one source over another and normalize the keys
> to dublin core or other standards.
> [~peterhoogendijk] and other users (likely?) want to be able to identify
> whether a given piece of information comes from the XMP or the docinfo. This
> is follow on work from TIKA-4444. The proposal is to add new metadata keys to
> specify when dublin core information comes directly from xmp.
