[open-bibliography] Comments on transformed BNB data

Tue Nov 23 12:33:24 UTC 2010

Using the prefix dc for the DC terms namespace is not incorrect, it is
merely unusual. DC terms does include all the 'legacy' terms and extends
it with a number of extra terms.

The reason why many use the dcterms vs dc prefix is by a rough
convention to let other people know that this is using the more up to
date namespace.

However, your point about the range of dc:issued being highly
restrictive is completely fair. Having to go back and use a namespace
that is already declared to be legacy may not be the best way forward.
If anyone has a suggestion as to which predicate we can use instead,
I'll be glad to hear it.
