Wouldn't you need to use two separate _occurrences_ of dcterms:extent,
one to record the duration and one to record the size?
If you want to indicate "encoding schemes" for duration and size, I
think you'd have to resort to schemes from a non-DCMI namespace, though,
because as Andy Powell suggests in one of the messages you cite
http://www.jiscmail.ac.uk/cgi-bin/wa.exe?A2=ind0110&L=dc-general&T=0&F=&
S=&P=141
W3CDTF doesn't cover all the bases for duration, and there isn't a
scheme in the DCQ rec for "size"....
So in RDF/XML something like:
<rdf:Description rdf:about="http://example.org/thing">
<dcterms:extent>
<foo:Seconds>
<rdf:value>123</rdf:value>
</foo:Seconds>
</dcterms:extent>
<dcterms:extent>
<foo:Bytes>
<rdf:value>123</rdf:value>
</foo:Bytes>
</dcterms:extent>
</rdf:Description>
Or following
http://dublincore.org/documents/2002/04/14/dc-xml-guidelines/
something like:
<qualifieddc>
<dcterms:extent scheme="Seconds">123</dcterms:extent>
<dcterms:extent scheme="Bytes">123</dcterms:extent>
</qualifieddc>
