You may add full Dublin Core metadata for every file uploaded.
You can access the metadata for a file from the record for the item to which it is attached. Either click on the link to File Metadata under the admin/items/show/ page or go to the edit page for the item, click on the File tab, and then click edit, as in the image below.
From the File Metadata page, you can edit the metadata for the file and also find links to the various versions of the file (for example, Original and Thumbnail files for an image).
