Hlaszny, E. - Muller, Christopher Johann (2026): VVO—Ontology for Cultivated Grapevine — The VVO (Vitis Vinifera Ontology) is a controlled vocabulary that formally describes the morphological structures, phenological growth and developmental stages, quality parameters, dispositions, roles, and information entities of Vitis vinifera L., the common grapevine. The VVO (comprises 3,333 annotated classes) is aligned with the Basic Formal Ontology (BFO 2020). A sophisticated ontology browser is also available. Published on NCBO BioPortal. Hlaszny, E. (2025): OCS—A Foundational Ontology for Computational Sociology — No ontology has been created in the general sociological subject area so far. The OCS (Ontology for Computational Sociology) makes a modest attempt at this. It is containing the ontology itself (URL): (700+ classes covering general sociology, 254 object properties, 78 data properties, and 201 n-ary causal relations—all properly mapped under BFO 2020 toplevel ontology classes), a web-based ontology browser, and development tools for extending the system. Published on NCBO BioPortal. Hlaszny, E. (20265: BDO—Building Domain Ontology — This guide presents a pragmatic methodology for developing applied domain ontologies. Emphasis is placed on modelling complex relationships including n-ary causal relations and interaction patterns that exceed simple binary predicates. Technical coverage encompasses OWL 2 DL, BFO 2020 alignment, reification patterns, and integration with semantic web infrastructure. Hlaszny, E. (2025): DBFOschemafy — A DB-Driven, BFO-annotated OWL Ontology Generator (on ResearchGate). DBFOschemafy is an advanced Java-based ontology engineering tool that leverages a relational database for input, overcoming the scalability limitations of its predecessor, OWLschemafy (see below), which relied on text files. Any control and source data, extended data, supplementary information, and author details are available electronically. Hlaszny, E. (2024): OWLSchemafy — A Java-based, Text-Driven Ontology Generator for Streamlined OWL (on ResearchGate). OWLschemafy presents a streamlined ontology development approach through a user-friendly text-based interface. OWLschemafy integrates with the Protégé Ontology Editor, permitting users to capitalize on the strengths of both applications. Fári, M.
