h1. Ontology Engineering

Ontology Engineering is a significant part of the project, although it is not listed as a separate pricing item.
- One of the most important parts of the system are annotations of various objects and parts of objects (eg image areas)
- An object part (eg painting area) can merit to be treated as "almost an object" on its own. Eg I may want to say "these are female hands", relate them to other painters who did similar subjects, identify a different technique or painting style, etc.
- And maybe there is need to annotate other annotations? Eg "X said S on date M, however Y disagreed with S because of T on date N:
- I'm no CRM expert, but is CRM rich enough to express such "Research Findings Ontology"?
- [] standards are cited, but again I am not sure they are enough. An annotation should be able to link to other semantic objects (collection objects, artists, techniques, etc).
- An integrated ontology is needed.

Is CIDOC CRM sufficient as a Research Findings ontology?
- maybe yes, since there entities such as Attribute_Assignment that record who determined what aspect of which object when
- even if not, it can be extended
- BM has some funds for CRM consultancy by Martin Doerr.
- obvious extension to CRM ontology will be the specification of the property P3F.has_note, types of Inscriptions, etc.
- an important addition to CIDOC-CRM will be the annotation ontology, which will extend its Attribute Assignment part.

h1. CRMdig
- Ontology for representing digitization processes, especially in archaeology, developed as part of 3D COFORM.
- included in the CRM conversion tool [], file 3D-COFORM_CRMdig_v2.5.rdfs
- includes entities such as D1.Digital_Object, D2.Digitization_Process, D3.Formal_Derivation, D8.Digital_Device, D9.Data_Object
