Apply metadata on multiple files in the Discovery Environment

It is possible to add or edit metadata on multiple files in the Discovery Environment by uploading a spreadsheet with this metadata.

The spreadsheet can be designed to follow a metadata format or standard, or contain whatever metadata entries you want associated with a set of files. See the for more details.

Output/Results

Although the file itself has not been edited, viewing the metadata in the Discovery Environment lets you view all annotations you have made to the file. View with metadata applied (you will need to view the file in the Discovery Environment to view the associated metadata; select the file and click More Actions and then Metadata).

Data Sharing in the Discovery Environment
