Hi Matei,

There are two different files here:

- Metadata set files describe a set of metadata elements. These are for
the GLI only, and are stored in the GLI's "metadata" folder. Typically
these are created/edited using the GEMS program, or by hand. You need to
add a metadata set to your collection (Design pane -> Metadata Sets)
before you can assign any metadata to files in the Enrich pane.

- Metadata.xml files store the metadata values assigned to files in the
collection. Metadata.xml files are stored in the "import" directory of
the collection (there is usually one per folder) and the GLI
reads/writes these as metadata is changed in the Enrich pane. When you
build a collection, the metadata.xml files are read by RecPlug (if
"-use_metadata_files" is on) and the metadata is assigned to the import
files.

I'm not sure whether you've generated one or both of these, but you need
to make sure the files you've generated are named correctly (".mds" and
"metadata.xml" respectively) and are the correct format. There are
examples of both in the Greenstone demo collection.

Regards,

Michael
