Resumen

Digital Twins (DTws) are a new category of technologies that enable construction industry to improve the precision of its predictions, make more logical decisions, and develop well-informed plans. To address these problems, it is essential to develop a method for semantically describing the various aspects that model the architecture of a DTw, i.e., representing DTws with formal semantics. This article introduces an extension of the W3C Web of Things (WoT) Thing Descriptions (TD) ontology, called “WoTDT” (WoT Digital Twin ontology). The WoTDT ontology is based on the most widely adopted architecture that models DTws into five dimensions. Furthermore, since the ontology has been created as a WoT extension, it will offer benefits such as enabling the discovery of services [1] across dimensions or enhancing the accessibility [2] of the information from a specific dimension, thereby promoting data interoperability. In addition, an evaluation of the ontology has been performed to ensure its quality by verifying that it is pitfall-free and covers all identified requirements. Finally, an example of the WoTDT ontology applicability is shown in the context of the European H2020 construction-related project COGITO.
