FAQs

What is the purpose of this class?

This class provides [CSDGM]-compliant metadata in the form of a graphical or multi-media representation that previews the content of its containing SEDRIS object. Its purpose is to allow a potential user of the attributed object to easily assess the utility of the attributed object.

How is the graphic or multi-media resource encoded? What format(s) can be used?

The resource is identified by a SEDRIS media URN which can be resolved to a URL for the resource. The URN contains a "media format tag" field. These tags are registered by the SEDRIS Organization to denote specific media formats. The resource may be encoded in any one of these registered formats.
