The key is flexible but clear rules.
First, define a core group of fields that are to be filled all assets. You will want that information which will aid in the management of the assets, such as:
- Location of digital file
- Usage rights
- Owner/creator of digital file
Secondly, define data standards before you start - i.e. decide what field will be used for which particular information. You can start with data standards developed for each specialty, but chances are you will also need to create a crosswalk for differing data standards. The important thing is to have each group use the assigned field for all the descriptive metadata, so that your crosswalks are accurate.
