Comparative Analysis and Synergy
Each review was prompted with the question:
Review and analyze the ontology at http://visualartsdna.org/model and thesaurus at http://visualartsdna.org/vocab that are used to model the visual arts creative process domain
Previously when google gemini was prompted for this analysis it had concluded:
The thesaurus and the ontology use different knowledge representation formalisms (SKOS and OWL, respectively). The concepts in the thesaurus serve as a vocabulary that can be used to populate or describe instances within the classes defined by the ontology. The hierarchical relationships defined using skos:broader in the thesaurus align with the class hierarchies defined using rdfs:subClassOf in the ontology. The organization of the thesaurus using skos:inScheme reflects different subject areas or modules within the ontology. The thesaurus and the ontology are intended to be semantically aligned and coherent, with the thesaurus providing the vocabulary for the domain modeled by the ontology. They work together to provide a structured representation of knowledge in the visual arts.
Now, a new round of reviews from several prominent AI platforms produced the following results.
OpenAI ChatGPT
I looked into the Visual Arts DNA site and found documentation for a model and thesaurus used to represent the art‐creation process—though note these aren’t directly mirrored on other major platforms, so much of the following is based on the descriptions and structure laid out at visualartsdna.org.
🧠 Ontology Overview
- Purpose & Scope
The Visual Arts DNA model represents the creative process of visual arts—from conceptual “idea” to executed work—capturing roles, stages, materials, actions, and outcomes. It’s designed as a formally structured ontology (likely OWL/RDF), aiming to foster interdisciplinary clarity and interoperability.
- Core Structure
- Entities: Includes agents (artists, collaborators), objects (tools, media), steps (e.g., ideation, sketching, fabrication), and artifacts (finished artworks, drafts).
- Relationships: Defines typical links like performsAction, usesMaterial, resultsIn, influencesBy, etc.
- Contextual Extensions: Includes metadata about time, place, influences, and socio‑cultural context—echoing CIDOC‑CRM’s handling of provenance and contextual info philarchive.org+1digitalartarchive.at+1research.vu.nlmdpi.com.
- Methodological Influences
The model draws inspiration from existing ontologies like CIDOC‑CRM and the Function‑Behavior‑Structure ontologies used in design modeling en.wikipedia.org. It also integrates situational layers—reflecting the ‘Descriptions & Situations’ framework (D&S) for contextual interpretation mdpi.com.
- Key Features
- Ontology-driven abstraction: Enables formal querying—“find artworks where 'materia' influenced tool selection”—and supports cross‑collection interoperability.
- Descriptor-level identity: Defines atoms like “brushstroke type X” as namable entities, enabling consistent tracking across works.
- Provenance & relationships: Tracks influences, roles, and processes akin to historical ontologies like HiCO and PHAROS .
- Representation‐agnostic: Designed to accommodate multiple interpretations—e.g., the same iconographic subject tagged differently—with contextual situational qualifiers mdpi.com.
- Strengths: Granular contextual modeling of materials, processes, roles; historically informed via rich art‑heritage ontologies.
- Gaps: Semantic depth for visual/formal attributes (shape, color, gesture) is limited—difficult to do image-based retrieval or compare formal features computationally. Also, contextual annotation appears to depend on curator input and isn’t fully automated.
🗂️ Thesaurus (Vocabulary)
- Structure & Format
The Visual Arts DNA vocabulary is presented as a SKOS-compliant thesaurus, organized hierarchically into facets such as Materials, Techniques, Roles, Concept, Tools, and Outcomes. This mirrors systems like Getty’s AAT or ADA thesauri getty.edu+1digitalartarchive.at+1.
- Terminology Layers
- Preferred terms for core entities (e.g., “oil paint”, “artist-in-residence”, “sketching”)
- Synonyms/alt labels to support semantic variation
- Broader/Narrower terms that help structure the domain ontology
- Definitions or scope notes for disambiguation
- Supports metadata consistency across records
- Enables faceted navigation (e.g., filter works by technique or material)
- Lays groundwork for hierarchical inference, e.g., "brush" is a tool, "paintbrush" is specific
- Strengths: SKOS allows integration with external vocabularies (AAT, ULAN) and supports semantic reasoning and linked-data applications.
- Gaps: Depth of terms is unclear—does every visual concept get covered? And are relationships between terms (e.g., technique to tool) well-mapped and documented?
🤝 Fit Between Thesaurus and Ontology
- The thesaurus provides vocabulary grounding for the ontology’s entities and relations.
- It enables data consistency for tagging and describing artworks and creative steps.
- The ontology uses thesaurus terms to build structured triples for reasoning—e.g., [Agent:Artist123] uses [Technique:Impasto] during [ProcessStage:Painting] using [Material:Oil Paint].
🔍 Recommendations & Opportunities
- Enrich visual/formal semantics: Add properties like “strokeType”, “hue”, or even integrate image-derived attributes (linked to COCO-style features).
- Clarify term coverage: Audit and extend the thesaurus to capture full domain scope—historic, experimental, digital art vocabularies.
- Demonstrate value: Provide practical SPARQL or visual search demos showing e.g., retrieval across collections by shared techniques or influence networks.
- Link to external ontologies: Ensure alignment with AAT, HiCO, PROV-O to maximize interoperability—automated mapping and reuse.
🔚 Summary
The Visual Arts DNA framework is a commendable step toward formalizing the creative process, merging structured metadata (ontology) with controlled vocabulary (SKOS thesaurus). It combines material, agentive, and contextual dimensions, positioning it well for domain interoperability. With further emphasis on visual feature modeling and richer semantic relationships, it holds strong potential for advanced artwork analysis and digital curation applications.

📌 Summary: VADNA is more suitable for modeling the dynamic creative lifecycle; AAT is better for generalized cataloging; ICONCLASS/ULAN better for subjects or biographic linkage.
🔧 5. Practical Complementarity
Vocabularies Working Together | Benefit |
VADNA + AAT | Use AAT terms for consistency in describing materials and techniques, while using VADNA to model the creation process and agent roles. |
VADNA + ICONCLASS | Use ICONCLASS for subject tagging of final artworks; VADNA for modeling how that content was produced. |
VADNA + PROV-O/CIDOC-CRM | Integrate fine-grained process modeling with established provenance standards. |
🧩 Key Takeaways
- VADNA is not a replacement for AAT or ICONCLASS but a complementary, process-oriented model focused on how artworks are made.
- AAT is ideal for classification; VADNA for creative semantics and dynamic processes.
- If you're working on creative process modeling, art education tools, or collaborative workflow tracking, VADNA provides the missing layer other vocabularies don't fully cover.

- Annotation Properties: cwva:hasVisualImagery is defined for cwva:Painting.
Many classes include skos:definition for clear descriptions and rdfs:isDefinedBy links to Wikipedia for external context.
Thesaurus Analysis (from http://visualartsdna.org/vocab)
The thesaurus available at http://visualartsdna.org/vocab also models the visual arts creative process domain, functioning as a controlled vocabulary. It primarily uses skos:Concept to define terms and skos:broader to establish hierarchical relationships, along with skos:definition for descriptions.
- Granularity: The thesaurus provides highly specific terms, particularly for:
- Watercolor painting: Includes materials like "ox gall," techniques like "opaque gouache contrast," and tools like the "shader" brush.
- Watercolor paints: Lists various colors with ARGB values, order, symbols, and associated brands (e.g., "Burnt Umber" by David Davis, "Cobalt Green Deep" by L. Cornelissen & Son).
- General painting processes: Such as "painting post production".
- Computer art terms: Including "informationalism" and "technicalism".
- General painting terms: Like "sizing," "masking tape," and "analogous colors".
Comparative Analysis and Synergy
The ontology and thesaurus, while distinct in their primary function, are complementary in modeling the visual arts creative process:
- Scope and Abstraction vs. Granularity and Specificity:
- Ontology (http://visualartsdna.org/model): Provides a high-level, structural, and conceptual framework for the domain. It defines the types of entities (classes) and the relationships between them (properties), focusing on the "how" and "what" in a broader sense of art creation (e.g., an Artist creates a CreativeWork using a Medium and Technique). It categorizes art movements, roles, and fundamental elements.
- Thesaurus (http://visualartsdna.org/vocab): Offers a more granular, detailed enumeration of specific terms and concepts within particular areas, such as detailed paint colors, unique materials, and specific tools. It serves as a comprehensive lookup for specific instances and finer-grained classifications.
- Formalism and Expressivity:
- Ontology: Leverages OWL and RDF Schema, allowing for explicit logical definitions of classes, subclasses, and properties (including domains and ranges). This enables more complex queries and inferencing, providing a robust backbone for knowledge representation.
- Thesaurus: Employs SKOS, which is optimized for managing hierarchical and associative relationships between concepts in controlled vocabularies. While it defines relationships, it doesn't support the same level of logical expressivity as OWL for defining complex axioms or constraints.
- Interoperability and Combined Utility:
- The ontology's import of skos:core and the use of skos:definition in both resources signify an intentional alignment. The thesaurus can effectively act as a detailed controlled vocabulary that populates or enriches the specific types of cwva:ArtMaterial, cwva:Technique, or cwva:Implement defined in the ontology. For example, a cwva:Pigment class in the ontology could be instantiated with specific pigment names listed in the thesaurus.
- The presence of the the: prefix in the ontology, even if not fully exploited in the provided snippet, suggests an intended integration where terms from the thesaurus could be linked to or used within the ontological framework.
In conclusion, the ontology provides a well-defined and extensible formal model for the visual arts creative process, outlining key entities, their types, and relationships. The thesaurus complements this by offering a rich, granular vocabulary of specific terms and their hierarchical organization. Together, they form a robust system for organizing, describing, and potentially reasoning about knowledge within the visual arts domain. The ontology provides the conceptual structure, while the thesaurus offers the detailed terminology.
