A spotlight on the ANDS Developer Tool Box -- getExtRif API The getExtRif API provides powerful access to the contents of the ANDS Collections Registry, much like the getRIFCS API. The important difference is that getExtRif includes an additional non-RIFCS element called -extRif:extendedMetadata-. During the processing of new records in the ANDS Registry, this element is populated with additional metadata about the record content and its context. This video gives a brief introduction to Extended RIF-CS (ExtRif) and the getExtRif API.
