Abstract
The perception of our heritage is based on sign-functions, which relate visual representations to cognitive types, allowing us to make perceptual judgements over physical objects. The recording of these types of assertions is paramount for the comprehension and analysis of our heritage. The article investigates a theoretical framework for the organization of information related to visual works on the basis of the identity and symbolic value of their single constituent elements. The framework developed is then used as a driver for the grounding of a new ontology called VIR (Visual Representation), constructed as an extension of CIDOC-CRM (CIDOC Conceptual Reference Model). VIR sustains the recording of statements about the different structural units and relationships of a visual representation, differentiating between object and interpretative act. The result, tested with data describing Byzantine and Renaissance artworks, presents solutions for describing symbols and meanings of iconographical objects, providing new clustering methods in relation to their constitutive elements, subjects or interpretations.
Highlights
The recording of the information related to a heritage object is constructed throughout the registration of different media items, which function as an anchor and representative in digital space of the original object/phenomenon
It is essential to reflect on the relationships between reality, person and image, analysing and integrating overarching theories developed within semiotics, art history, digital humanities and information science
We define a semantic mark as the result of a function which relates the signals to a situation and a physical thing to create denotative expressions that link the initial signals to specific cultural content
Summary
The name is, significant, because the scope of the ontology is the formalisation of the relationships between the visual representations and symbols that characterise a single artwork or are distinctive of a social arena. VIR is grounded on the semiotic distinction between expression and content, and introduces class and properties for annotating pictorial elements that compose visual works and their denoted/connoted conceptual elements
