Presentation overview
• Why to develop ontology of the Bulgarian iconographical artefacts?
• In search of similar ontologies and standards, that could help the ontological representation of the iconographical knowledge
• Ontology of the Bulgarian iconographical artefacts
• Multimedia digital library “Virtual encyclopedia of Bulgarian iconography” and ideas for implementation of new semantic-based services
Fifth HUBUSKA Workshop, Kosice, Slovakia, 31 May – 1 June, 2007
Motivation
• Extension and improvement the functionalities and services in the MDL “Virtual encyclopedia of Bulgarian iconography”
• Content- and context-sensitive services for access, browse, search and group of iconographical objects
• Presentation the iconographical knowledge in explicit, systematized and clear way
• Provision of the basis for future extension of the ontological representation and description of the iconographical knowledge
Fifth HUBUSKA Workshop, Kosice, Slovakia, 31 May – 1 June, 2007
Similar ontologies and standards
• art-E-fact ontology [Marcos et al. ,’05]
• Ontology of art [Thomasson, ’04]
• CIDOC оbject-oriented Conceptual Reference Model (CRM)– International Committee for Documentation of the
International Council of Museums
– ”Object-oriented domain ontology" for expressing the implicit and explicit concepts in the documentation of cultural heritage
– Role: enable information exchange and integration between heterogeneous sources of cultural heritage information.
– Final version: CIDOC CRM version 4.2
– Official standard: ISO 21127:2006 since 9/12/2006
– Available at: http://cidoc.ics.forth.gr/

Ontology of Bulgarian iconographical artefacts
Main purpose, scope, and usage
Purpose
– Presentation of the semantic of Bulgarian
iconographical objects, registered in multimedia
digital library “Virtual encyclopedia of Bulgarian
iconography”, painted by different artists from four
iconographic schools, dated from several centuries,
and located in Bulgaria.
– Provision of a basis for content-sensitive services in
the “Virtual encyclopedia of Bulgarian iconography”Fifth HUBUSKA Workshop, Kosice, Slovakia, 31 May – 1 June, 2007
Ontology of Bulgarian iconographical artefacts
Main purpose, scope, and usage

century

Conceptualization
The knowledge about iconographical artefacts is related to three “thematic entities”:
• Identification - General data such as title, type, author, clan, iconographic
school, period, dimensions, location, etc.
• Description- Scenes and characters, participation in scenes, etc.
• Technical- Used techniques, base material, diagnosis or conservation
treatment, etc.
