[jira] Created: (TIKA-452) Extract custom pdf metadata
Extract custom pdf metadata
---------------------------
Key: TIKA-452
URL: https://issues.apache.org/jira/browse/TIKA-452
Project: Tika
Issue Type: Improvement
Components: parser
Affects Versions: 0.7
Reporter: Nick Burch
Assignee: Nick Burch
Priority: Minor
Fix For: 0.8
While PDF files can contain custom metadata, we currently don't extract this
Given that other parsers currently do for their formats' custom metadata, and PDFBox makes the custom metadata available (in a not too nasty way), the pdf parser should do too

---------------------------------
Jeremias - thanks for the PDF. Unfortunately, I'm not seeing the custom metadata come through :( It only seems to have the normal metadata entries:
COSName{Author} Author
COSName{Creator} Creator
COSName{CreationDate} CreationDate
COSName{ModDate} ModDate
COSName{Producer} Producer
COSName{Title} Title

--------------------------------------
I can generate a small PDF for you with Apache FOP, if you want.

[jira] Resolved: (TIKA-452) Extract custom pdf metadata
Posted by "Nick Burch (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/TIKA-452?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Nick Burch resolved TIKA-452.
-----------------------------
Resolution: Fixed
Feature added in r959275.
However, no unit test exists for this, as the only file I have with custom metadata in it is much too large. It would be good if we can find a nice small pdf with some custom metadata in it for testing

---------------------------------
I used pdfbox to add in some custom metadata to your sample file, then used that as a basis for a test. Committed in r959305. We now also have that file in SVN for testing future XMP related metadata extraction enhancements

---------------------------------
Sounds like there's another kind of metadata we should be extracting too then!

Jeremias Maerki commented on TIKA-452:
--------------------------------------
Ah, I see, you were talking about the old Info dictionary. I thought this was about XMP metadata. In that case, I can't really help because I can't add custom metadata to the Info dictionary with FOP.
