The Reasonable Ontology Templates Framework

Authors: Martin Georg Skjæveland and Leif Harald Karlsen

Published in: TGDK, Volume 2, Issue 2 (2024): Special Issue on Resources for Graph Data and Knowledge. Transactions on Graph Data and Knowledge, Volume 2, Issue 2

Abstract
Reasonable Ontology Templates (OTTR) is a templating language for representing and instantiating patterns. It is based on simple and generic, but powerful, mechanisms such as recursive macro expansion, term substitution and type systems, and is designed particularly for building and maintaining RDF knowledge graphs and OWL ontologies. In this resource paper, we present the formal specifications that define the OTTR framework. This includes the fundamentals of the OTTR language and the adaptions to make it fit with standard semantic web languages, and two serialization formats developed for semantic web practitioners. We also present the OTTR framework’s support for documenting, publishing and managing template libraries, and for tools for practical bulk instantiation of templates from tabular data and queryable data sources. The functionality of the OTTR framework is available for use through Lutra, an open-source reference implementation, and other independent implementations. We report on the use and impact of OTTR by presenting selected industrial use cases. Finally, we reflect on some design considerations of the language and framework and present ideas for future work.

Hybridisation of Institutions in HETS (Tool Paper)

Authors: Mihai Codescu

Published in: LIPIcs, Volume 139, 8th Conference on Algebra and Coalgebra in Computer Science (CALCO 2019)

Abstract
We present a tool for the specification and verification of reconfigurable systems. The foundation of the tool is provided by a generic method, called hybridisation of institutions, of extending an arbitrary base institution with features characteristic to hybrid logic, both at the syntactic and the semantic level. Automated proof support for hybridised institutions is obtained via a generic lifting of encodings to first-order logic from the base institution to the hybridised institution. We describe how hybridisation and lifting of encodings to first-order logic are implemented in an extension of the Heterogeneous Tool Set in their full generality. We illustrate the formalism thus obtained with the specification and verification of an autonomous car driving system for highways.
