[DSpace 7 Upgrade] Configure import sources for metadata extraction

[wwelling]

Unable to submit item using standard bibliographic formats as documented.

Should be able to upload an EndNote, RIS, or BibTex file to begin a submission.

In testing on labs, uploading standard bibliographic files as documented at https://wiki.lyrasis.org/pages/viewpage.action?pageId=104566672#ImportingItemsviabasicbibliographicformats(Endnote,BibTex,RIS,CSV,etc)andonlineservices(arXiv,PubMed,CrossRef,CiNii,etc)-Submittingstartingfrombibliographicfile does not seem to populate any of the metadata. I am unable to attach test records to this note, but examples can be found on TDR by exporting citations on an item: https://dataverse.tdl.org/dataverse/tamul_dams_eval
