Hi Câ–¡cile,

>(I'm running Greenstone 2.70w on W-XP. Sorry for the basic questions, but I've searched in the doc and archives from this list for answers without any luck).

I'm not quite sure what you mean here. If you want your metadata set to
be an extension of Dublin Core, you should base your new set on Dublin
Core when creating it.

The GLI has simple metadata requirements, and doesn't use many of the
attributes that you might find in the metadata set files. The ones it
does use are:

Metadata sets: namespace
Metadata elements: identifier, definition, comment

Everything else you can ignore.

The "datatype" attribute is not used. (I think it is there because the
metadata set was generated from the Dublin Core specification).

Not at this stage sorry; Greenstone/GLI does very little in terms of
metadata validation.
