OPM: An ontology for describing properties that evolve over time

Abstract

International audienceThe W3C Linked Building Data on the Web community group discusses different potential patterns to associate values to properties of building elements. In this paper, we are interested in enabling a different value association method for these and other properties, to account for changes in time, or to annotate a value association with metadata such as provenance, reliability and origin data. Existing ontologies in the Architecture, Engineering and Construction (AEC) industry are reviewed first and we motivate the use of the Smart Energy-Aware Systems (SEAS) ontology as a starting point. Next, we list new competency questions to represent the aforementioned metadata and develop an extension of SEAS named the Ontology for Property Management (OPM). We illustrate the use of OPM with different scenarios where a value association needs to be annotated or updated in a dataset using SPARQL update queries
