sorry i have missed you, but hope this helps.

i am not sure i exactly grasp your question about "I believe the intention is
that whole
schemas and schema fragments will typically be held, but not down to the
data element level (e.g. a quantity). "

I have had a look at the work RegRep are doing in  this area and my summary is:-

i quite like the RegReps view of the 4 layers (M0,M1,M2, M3), where..

M0 is the data instances (data element value)- (maybe these are 'objects'?)
M1 is the metadata model (down to data element data) - (maybe these are 'object
M2 is the metamodel (data about metadata models)
M3 is the meta-metamodel (data about modelling techniques)

RegRep propose the repository holds the M3 layer information and the registry
holds M1 level data for the meta-metamodels.

in this case wouldn't a repository object describe how to model data elements
but not necessarily holding schemas OR fragments OR elements?  what goes in
there depends on the individual use.

RegRep have developed a set of 'classifications' of the type of things you may
find in the repository


so... i think we do need a clearer definition

any volunteers?
