Functional Location Ontology Design Pattern (FL-ODP): OWL artifact, SPARQL competency questions, and validation dataset

This record archives the artifact accompanying the FOIS 2026 paper "An Ontology Design Pattern for Functional Locations in Industrial Asset Management." The Functional Location Ontology Design Pattern (FL-ODP) separates five concerns of an industrial functional location: the persistent location (a bfo:Site), its functional-location code and equipment tag (two centrally registered identifiers that both denote the location), its specification (a directive information entity), and the installed equipment (a material artifact). The deposit contains: the OWL 2 DL ontology (odp-fl.ttl, v0.8, verified consistent with HermiT); an optional IOF-Maintenance bridge extension (odp-fl-maint.ttl); the bundled upper-ontology imports (BFO 2020, IAO, IOF Core 202602, IOF Annotation Vocabulary 202602) with an OWL catalog (catalog-v001.xml) for offline reasoning; seven SPARQL competency-question queries (cqs/cq1.rq through cq7.rq) and a runner; and an anonymized validation dataset from an offshore petroleum platform (a pressure-transmitter position with three documented sensor replacements, a maintenance note, and a ten-year measured time series indexed by the site). The ontology is also published at its resolvable IRI: https://www.inf.ufrgs.br/ontologies/odp/functional-location.
