All, I received a private email asking if it is possible to recursively extract attachments with /unpack.
It isn't currently possible with /unpack or with the -z option in tika-app. As the writer acknowledged, users can get recursive text+metadata with the /rmeta endpoint. However, /unpack currently only works on the attachments of the primary file -- it doesn't operate recursively on those attachments. I opened: https://issues.apache.org/jira/browse/TIKA-3703 to discuss implementing the frictionless format for this kind of thing. If we went this route, I'd be slightly inclined to start a new endpoint rather than adding parameters to the existing /unpack endpoint. What do you think? Best, Tim
