Hi Andrew,
I think identifiers for metadata records can go as high as database
column types and resources permit - resource directories (for thumbnails
and uploads) are created to match the id as required (see
src/org/fao/geonet/lib/ResourceLib.java).
For issues with deleting records - I think the ids can actually get
re-used (eg. delete, stop geonetwork, then start, then create) - clashes
are possible.
The trunk doesn't actually delete the resources for single metadata
delete - BlueNetMEST does. MassiveDelete doesn't delete resources on
either trunk or BlueNetMEST (and this is a bug on BlueNetMEST which
dates from when MassiveDelete was brought in to BlueNetMEST from the
trunk - I'll fix it shortly).
From my point of view, I think the trunk should be updated to delete
the resources after they've been backed up as part of the MEF that is
made when a metadata record is deleted. Perhaps someone with more
knowledge about why the trunk doesn't delete these resources may want to
comment on whether this is a good idea/necessary.
Cheers and thanks,
Simon
