Nick Burch commented on TIKA-1109:
----------------------------------
This is a limitation of using the tika-app jar. The tika-app jar will give you
either metadata (--metadata) or text (--text / --xml). Tika itself generates
both at the same time, so for more advanced uses you'll be better off calling
the API directly yourself.
> Metadata not extracted before the context in OOXML (pptx)

> Key: TIKA-1109
> URL: https://issues.apache.org/jira/browse/TIKA-1109
> Project: Tika
> Issue Type: Bug
> Reporter: Daniel Bonniot de Ruisselet
> Priority: Critical
> Fix For: 1.4
>
>
> It seems that when processing OOXML documents, the metadata is only read
> after the text. This means it's impossible to use the medata while processing
> the text. I think it would be more useful to have the metadata populated
> first.
> As a symptom:
> java -jar tika-app-1.3.jar test-classes/test-documents/testPPT.pptx
> outputs only as metadata:
> <meta name="Content-Length" content="36518"/>
> <meta name="Content-Type"
> content="application/vnd.openxmlformats-officedocument.presentationml.presentation"/>
> <meta name="resourceName" content="testPPT.pptx"/>
> while there is more medata in the file (e.g. <dc:title>Attachment
> Test</dc:title>).
