Some questions: 1. The definitions {{{ dc.language = element dcterms:language { element rdf:Description { element dcq:languageScheme { "ISO 639-2" }, rdf.value } } dc.date = element dcterms:date { element rdf:Description { element dcq:dateScheme { "ISO 8601" }, rdf.value } } }}} seem to be obsolete. Especially dcq seems obsolete. I have replaced them by something which I believe is in accordance with Recommendation 7 in the [http://dublincore.org/documents/2003/04/02/dc-xml-guidelines/ 2003 XML Guidelines]: {{{ dc.language = element dcterms:language { attribute xsi:type { "dcterms:ISO639-3" }, text } dc.date = element dcterms:date { attribute xsi:type { "dcterms:W3CDTF" }, text } }}} (Maybe I should have left {{{}}} instead of "text"? But then, consequently ALL "text" in {{{dcterms}}} definitions should in fact be {{{}}}.) However, information is sparse. The syntax encoding schemes {{{dcterms:W3CDTF}}} and {{{dcterms:ISO639-3}}} do exist according to [http://dublincore.org/documents/dcmi-terms/ DCTERMS], but an up-to-date opionion about how to use syntax encoding schemes is difficult to obtain. The proposed recommendation [http://dublincore.org/documents/2008/09/01/dc-ds-xml/ 2008 XML Guidelines] uses {{{dcterm:date}}} only like this: {{{ 2005-05-05 2005-05-05 }}} Any suggestions? 2. Should we rename our {{{}}} element? In all examples it is {{{}}}. However, in most examples it seems to mean the repository version of the metadata, not the version in the xml file itself. 3. Do we need something like {{{}}} for creators, contributors, etc.? (I guess not; it doesn't seem have any particular advantage.)
