Hi MacKenzie

I think it is quite hard to say whether CIDOC or Harmony is a preferred
solution:

- CIDOC is richer than Harmony; but this also means it is more complicated
e.g. CIDOC has approximately 75 classes and 105 properties, Harmony has
approximately 13 classes and 20 properties

- CIDOC was originally developed using TELOS, a different way of encoding
semantic networks predating RDF, but both Harmony and CIDOC are expressable
in RDF / RDFS

- There is an interesting discussion of the approach adopted when creating
CIDOC here
http://cidoc.ics.forth.gr/docs/crm-ontology_preprint.pdf

- There seems to be a standards activity around CIDOC, whereas there is no
formal standards activity around Harmony. This means it may be easier to
introduce changes into Harmony, or conversly CIDOC is potentially more
stable

- CIDOC is on track to be an ISO standard, although I note that this tends
to hold little sway with the web community

Do you have any other observations?
