Ray,

My reason for using tel.creator etc. is that these indexes correspond to a
set of indexes used for a specific purpose: the tel portal.

Some are similar, but not necessarily identical to equivalent dc indexes.

The server does respond to some dc.indexes (e.g. dc.title) and at some stage
in the near future these will be mapped to the tel indexes where
appropriate.

I take the title element to be a label that could be used in a search input
screen. I agree it would be useful to include a description with the index
definition in the explain response.

Could you please explain the issue about the "index naming convention".

Bill

If tel.creator is intended to have different semantics than dc.creator, that
is sufficient reason.  (Although if these adhered to the index naming
convention this would be easier. Different issue though.)

It's not easy to tell from the explain info the semantics of tel.creator (or
for that matter any of the indexes).  What is the convention for expressing
semantics of an index? In the <title> element?  Would it be reasonable to
ask that a <description> be added for indexes? (As there is one for
databases.)
