Top Supported Tags

Initial Identification

The following table shows the tags that had the broadest level of support in the group, based on a fast 'straw poll', and also the number of formats for which there is a mapping of that tag. In the following table, "Entity" is either a "Resource" (abstract concept) or a "Representation" (instance/file); It can be a single object or composed of fragments.

Next Steps

Review the selected attributes, see

• whether there are missing attributes that we should add to the table
• whether there are attributes that should be combined or split
• how the selected attributes map from all the given input formats; whether data conversion is needed etc.

  (if the call is to retrieve X and your input format is Y, then do Z)

• is the attribute expected to have a unique value (only 0 or 1 returned result), or a plurality?
• there are attributes (contributor, relation) where the 'nature' terms need a set definition
• each attribute needs a bit more text on the value, explaining what it should be, to guide those doing mapping

See how the selected set helps solve the use cases
