  • nen2660 - NEN 2660-2:2022 'Rules for information modelling of the built environment - Part 2: Practical configuration, extension and implementation of NEN 2660-1''
    https://w3id.org/nen2660/
    Ontology which is a normative part of the Dutch NEN 2660-2 standard @en
  • opm - OPM: Ontology for Property Management
    https://w3id.org/opm
    The Ontology for Property Management (OPM) extends the concepts introduced in the Smart Energy Aware Systems (SEAS) Evaluations ontology. @en
  • opti - Offshore Wind Power Platform Ontology for OPTiMAR
    https://w3id.org/optimar
    This ontology describes the components, failures, sensors, and events related to offshore wind platforms. @en
  • otl - The Open Traffic Lights ontology
    https://w3id.org/opentrafficlights
    This ontology provides the terms necessary to describe the status of traffic lights. @en
  • ofo - Occupant Feedback Ontology
    https://w3id.org/ofo#
    The aim of the Occupant Feedback Ontology is to semantically describe passive and active occupant feedback and to enable integration of this feedback with linked building data. @en
  • peco - The Provenance of Emission Calculations Ontology
    https://w3id.org/peco
    This ontology defines a vocabulary for describing provenance traces of carbon emission calculations by capturing the quantifiable measurements of carbon emission sources used by some activities (e.g., electricity used by a machinery to produce a product, petrol used to make a car journey, etc.) and emission conversion factors used to estimate the carbon emissions produced by these. In addition, the ontology provides the ability to capture various data transformations that occurred before energy estimates may be used with relevant conversion factors. For example, sensors may provide raw readings about a water flow of an irrigation rig in an agri-food operation which is then used as a proxy to estimate the total volume of fertilisers used. @en
  • pep - Process Execution ontology.
    https://w3id.org/pep/
    The process execution ontology is a proposal for a simple extension of both the [W3C Semantic Sensor Network](https://www.w3.org/TR/vocab-ssn/) and the [Semantic Actuator Network](https://www.irit.fr/recherches/MELODI/ontologies/SAN.owl) ontology cores. @en
  • seas-op - The SEAS Failable System ontology
    https://w3id.org/seas/OperatingOntology
    The SEAS Operating Ontology defines evaluations of operating features of interest. @en
  • seas-qudt - QUDT Alignment.
    https://w3id.org/seas/QUDTAlignment
    This ontology defines proposed alignemnts with the QUDT ontology. @en
  • seas-stats - The SEAS Statistics ontology.
    https://w3id.org/seas/StatisticsOntology
    This ontology defines common evaluation interpretation concepts for statistics. @en
  • seas-sys - The SEAS System ontology
    https://w3id.org/seas/SystemOntology
    The System Ontology defines Systems, Connections between systems, and Connection Points at which systems may be connected. This ontology is then specialized for multiple domains. For example: - In electric energy: - power systems consume, produce, store, and exchange electricity; - power connections are where electricity flows between systems; - power connection points are plugs, sockets, or power busses. - In the electricity market: - players and markets are systems; - connections are contracts or transactions between two players, or between a player and a market; - connection points include offers and bids. @en
  • seast - The SEAS Time Ontology.
    https://w3id.org/seas/TimeOntology
    This ontology defines: - a set of subclasses of `seas:Evaluation` to better interpret evaluations of quantifiable properties. - a set of sub properties of `seas:hasProperty` to qualify time-related properties. @en
  • seasd - The SEAS Device ontology
    https://w3id.org/seas/DeviceOntology
    The SEAS Device ontology defines `seas:Device` as physical system that are designed to execute one or more procedures that involve the physical world. @en
  • seasfo - The SEAS Forecasting ontology
    https://w3id.org/seas/ForecastingOntology
    The SEAS Forecasting ontology extends the [Procedure Execution ontology (PEP)](https://w3id.org/pep/) @en
  • seas - SEAS ontology
    https://w3id.org/seas/
    This vocabulary is version v0.1 of the ITEA2 Smart Energy Aware Systems project vocabulary. It enables the description of electricity measurements of a site using the Data Cube W3C vocabulary. @en
