I would describe RLLOMAP (which is short for the "RDN/LTSN LOM
Application Profile" and pronounced rolo-map or role-mop depending on
who you ask - duh, which idiot came up with that name!? :-) ) as an
application profile of IEEE LOM, and which is closely aligned with, but
as far as I remember not 100% compatable with, UK LOM Core. The
incompatability with UK LOM Core is one thing that I'd like to sort out
at some point - at least to try and understand exactly why there are
differences. Though some of this has probably been thrashed out in past
discussions on this list.

There is some work going on at the moment in the form of a Joint
DCMI/IEEE LTSC Taskforce
http://dublincore.org/educationwiki/DCMIIEEELTSCTaskforce
which is looking at aligning IEEE LOM with the Dublin Core Abstract
Model. This work will hopefully result in us being able to combine
usage of all DCMI and LOM metadata terms and encode the resulting
metadata using any of the encoding syntaxes currently supported by DCMI
(XHTML meta tags, XML and RDF). Look at the 'documents' section of the
Wiki above to see the current state of this work.

For info, some time ago I successfully configured an instance of the
eprints.org software to work with a relatively simple profile of IEEE
LOM (probably RLLOMAP I guess). As far as I recall, it wasn't that hard
to do this. Unfortunately, in a classic case of poor planning, I failed
to either document exactly what I'd done or ensure that the machine I'd
done in on was backed-up reliably - as a result, I don't think I can go
back and show people exactly what I did :-(. But as I think I noted at
the time, configuring the eprints.org software to support LOM wasn't
that hard, adding proper support for content packaging would be much
more difficult. So although my experimental eprints.org LOR could treat
IMS CP packages as 'black box' blobs of data, it didn't have any
knowledge about how to unpack/pack them - and adding support for this
would have been non-trivial, at least in the version of eprints.org that
I was using at the time.
