>                 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.
