Hi Peter, I’m not referring to metadata extraction, rather the bitstream File Description field that can be filled out when uploading a file into an Item.
We want to add a couple more fields to the bitstream’s metadata during the upload process and have those fields be searchable. Fields we want to add to the file upload form include: Type (for generic dcmitype values), Description (file description), Dimensions (page or image size), No. Pages (number of pages), etc… As it is, the bitstream’s description field is not appearing in search results. We’ve assumed it is being stored as a dc.description field just like the Item, but I’m not sure that is the case… Is bitstream metadata (description, file type, file size, etc…) treated the same as Item metadata? Can it be searched and found from within DSpace’s search box?

I'm not aware of file metadata extractors available for Java, but from the terminal, I sometimes use "exiftool" to see information in the bitstream.

The only problem we have with this is that the bitstream metadata is not searchable by default in DSpace. So, I’m trying to figure out how to search bitstream metadata (for example, the description field), or include bitstream metadata in the Discover module. Could someone please comment on how to enable this?
