The lightweight allow the representation and use of IoT platforms without consuming excessive processing time when querying the ontology. However it is also a meta ontology that can be extended in order to represent IoT concepts in a more detail way in different domains."@en ; dc:description """This ontology describes IoT concepts into three classes. Objects, system or resources and services. The devices are also splitted into, although not restricted to, three classes: sensing devices actuating devices and tag devices. The services are described with an availability or access control and a coverage. This coverage represents the area covered by the IoT device. The figure below depicts the concepts of the ontology and the main relationships between them. IoT Lite Ontology is created to be used with a common taxonomy to describe the Units and QuantityKind that IoT devices can meassure. This taxonomy represent individuals in the ontology and is based in well-known taxonomies as: qu and qudt."""@en ; dc:rights "This ontology is distributed under a Creative Commons Attribution 3.0 Unported License - http://creativecommons.org/licenses/by/3.0/.
