New metadata field in files

[Fatima Caballero]

Hello, I hope you are well. I am installing Dspace 7, and was seeing if there is a possibility to add a new metadata field to the file. The files I know record name, description and format. I would like to know if a metadata (tag type) can be added to the file, and if this metadata can be indexed to search the file.
Thank you, Yours sincerely,

It's possible but you have to provide more details. In general you can use one of DSpace predefined Metadata Schema ( https://you-dspace-server-url/admin/registries/metadata ) or you can add your own. Read about it in the documentation here https://wiki.lyrasis.org/display/DSDOC7x/Metadata+and+Bitstream+Format+Registries

Thank you very much for your reply.I am interested in adding a new metadata in submission-forms.xml in the "bitstream-metadata" section. I want the bitstream to store a new metadata similar to dc.subject, which is of type tag. I know it is possible to customize the metadata that is requested during upload. I created a new metadata field in the dublin-core schema and added it to the mentioned section. But the problem occurs when I want it to search for that metadata.  I can't find a way to have it indexed so I can search for it.

Out of the box added custom metadata to submitted/uploaded/ingested items should be searchable if Solr discovery is reindexed after the items are submitted ( [dspace]/bin/dspace index-discovery ). I had no problem finding any custom added metadata or the specific values of these metadata's using Boolean Operators too ( an email address for instance ).
