Abstract

SICON is an ontology design pattern for representing the spatial configuration of visual elements distributed across the surfaces of three-dimensional built structures and cultural heritage objects. SICON separates the material carrier from the visual item so that configurational relations survive total material loss. It is interoperable with, but not a formal extension of, the ICON and VIR ontologies.

Introduction back to ToC

Iconographic programmes on built heritage, such as heraldic murals spread across the walls, ceilings, and beams of a room, derive much of their meaning from where their elements are placed relative to one another. Existing cultural heritage ontologies describe either the objects themselves (e.g. CIDOC CRM) or what individual images depict (e.g. Iconclass, VIR, ICON), but not the spatial configuration of visual elements within and across the surfaces of a single three-dimensional object.

SICON (Spatial ICONography) is an ontology design pattern that addresses this gap. It rests on two design decisions:

The pattern was developed for heraldic murals of medieval and early modern Europe, but is designed to apply to other decorated three-dimensional objects as well. It does not model iconographic meaning itself; iconographic vocabularies and ontologies can be attached to its classes. The alignment to CIDOC CRM (v7.1.3) is published as a separate module, so the pattern can be reused without committing to a particular upper model.

For diagrams and the competency questions the pattern is derived from, see the Description. SICON is presented in detail in: TODO: add CEUR citation.

Description back to ToC

SICON models where visual elements sit in relation to one another within an iconographic programme, rather than what those elements depict. It is built on two aspects. First, the material stratum of a mural (sicon:PaintedDecoration) is kept apart from the visual composition it bears (sicon:ConceptualVisualRepresentation), so that configurational assertions remain available, attested only through written or drawn sources. Second, spatial relations are expressed mereotopologically rather than through absolute coordinates, so that incomplete and fragmentary evidence can be recorded without silently supplying a plausible reconstruction.

The pattern is derived from the following competency questions:

SICON separates the material carrier of a visual element from the visual item it bears, so that spatial relations between visual items remain representable even after partial or total material loss.

                PaintedDecoration as a subclass of CIDOC CRM E25 Human-Made
                Feature, with MuralConditionState and its subclasses. On the
                right, the visual representation side:
                ConceptualVisualRepresentation as a subclass of E36 Visual
                Item, with MuralSegment and IconographicRepresentation.

Diagram, depicting the hierarchy of the meretopological properties of SICON, used for describing spatial relations between visual entities. The property hierarchy is split between 'topological relations', which describe how two things are related to each other as areas (overlap, spatially disconnected etc.) and directional relations, that describe in which directions two things are placed (left of each other, above of etc.)

Alignment to CIDOC CRM is published as a separate alignment file, so that the pattern can be reused without committing an adopter to a particular upper model.
