  • dk - The Data Knowledge Vocabulary
    http://www.data-knowledge.org/dk/
    The Data Knowledge Vocabulary allows for a comprehensive description of data assets and enterprise data management. It covers a business data dictionary, data quality management, data governance, the technical infrastructure and many other aspects of enterprise data management. The vocabulary represents a linked data implementation of the Data Knowledge Model which resulted from extensive applied research. @en
  • gn - The Geonames ontology
    http://www.geonames.org/ontology
    The Geonames ontology provides elements of description for geographical features defined in the geonames.org data base @en
  • ivoam - Messengers
    http://www.ivoa.net/rdf/messenger
    A vocabulary of particles used for observations in astronomy. This list started its existence as the controlled vocabulary for VODataService's vs:Waveband type; the machine-readable identifiers are in upper case for backwards compatibility. @en
  • ioto - IoT-O
    http://www.irit.fr/recherches/MELODI/ontologies/IoT-O
    IoT-O is a core domain Internet of Things ontology. It is intended to model horizontal knowledge about IoT systems and applications, and to be extended with vertical, application specific knowledge. It is constituted of different modules : - A sensing module, based on W3C's SSN (http://purl.oclc.org/NET/ssnx/ssn) - An acting module, based on SAN (http://www.irit.fr/recherches/MELODI/ontologies/SAN) - A service module, based on MSM (http://iserve.kmi.open.ac.uk/ns/msm/msm-2014-09-03.rdf) and hRest (http://www.wsmo.org/ns/hrests) - A lifecycle module, based on a lifecycle vocabulary (http://vocab.org/lifecycle/schema-20080603.rdf) and an iot-specific extension (http://www.irit.fr/recherches/MELODI/ontologies/IoT-Lifecycle) - An energy module, based on powerOnt (ttp://elite.polito.it/ontologies/poweront.owl) IoT-O developping team also contributes to the oneM2M IoT interoperability standard. @en
  • SAN - SAN (Semantic Actuator Network)
    http://www.irit.fr/recherches/MELODI/ontologies/SAN
    This ontology is intended to describe Semantic Actuator Networks, as a counterpoint to SSN definition of Semantic Sensor Networks. An actuator is a physical device having an effect on the world (see Actuator for more information). It is worth noticing that some concepts are imported from SSN, but not SSN as a whole. This is a design choice intended to separate as much as possible the definition on actuator from the definition of sensor, which are completely different concept that can be used independantly from each other. This ontology is used as a ontological module in IoT-O ontology. @en
  • geof - Geo Features
    http://www.mindswap.org/2003/owl/geo/geoFeatures20040307.owl
    This ontology contains geographic feature classes and associated properties including classes and properties for describing the spatial location of the geographic feature. The classes and properties have been defined based on an ESRI dataset. @en
  • ceo - Consumer Electronics Ontology
    http://www.ebusiness-unibw.org/ontologies/consumerelectronics/v1
    An Ontology for Consumer Electronics Products and Services @en
  • oum - Ontology of units of Measure (OM)
    http://www.ontology-of-units-of-measure.org/resource/om-2/
    The Ontology of units of Measure (OM) 2.0 models concepts and relations important to scientific research. It has a strong focus on units, quantities, measurements, and dimensions. @en
  • ostop - Ordnance Survey Topography Ontology
    http://www.ordnancesurvey.co.uk/ontology/Topography/v0.1/Topography.owl
    The general purpose of this ontology is to provide a library of high level concepts that are used by the other modules within the whole OS Topographic ontology. The ontology also describes the relationships and instances common to more than one module. @en
  • traffic - Road Traffic Management
    http://www.sensormeasurement.appspot.com/ont/transport/traffic
    An ontology that describes the management of the traffic in a straight road with two lanes, both in the same direction. @en
  • geo - WGS84 Geo Positioning
    http://www.w3.org/2003/01/geo/wgs84_pos
    A vocabulary for representing latitude, longitude and altitude information in the WGS84 geodetic reference datum. @en
  • locn - ISA Programme Location Core Vocabulary
    http://www.w3.org/ns/locn
    The ISA Programme Location Core Vocabulary provides a minimum set of classes and properties for describing any place in terms of its name, address or geometry. The vocabulary is specifically designed to aid the publication of data that is interoperable with EU INSPIRE Directive. @en
  • ssn - Semantic Sensor Network Ontology
    http://www.w3.org/ns/ssn/
    This ontology describes sensors, actuators and observations, and related concepts. It does not describe domain concepts, time, locations, etc. these are intended to be included from other ontologies via OWL imports. @en
  • uiot - Urban IoT Ontologies - Core Module
    http://www.w3id.org/urban-iot/core
    Core module of the suite of ontologies for urban IoT devices. @en
  • uiote - Urban IoT Ontologies - Electric Mobility Module
    http://www.w3id.org/urban-iot/electric
    Electric Mobility module of the suite of ontologies for urban IoT devices. @en
