  • 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
  • dtype - Datatype Ontology
    http://www.linkedmodel.org/schema/dtype
    The ontology 'dtype' provides a specification of simple data types such as enumerations. These are needed in support of the conversion of XML Schemas and UML Models to OWL. Codelists are also defined in 'dtype'. @en

  • prof - Profiles Vocabulary
    http://www.w3.org/ns/dx/prof
    This vocabulary is for describing relationships between standards/specifications, profiles of them and supporting artifacts such as validating resources. This model starts with [http://dublincore.org/2012/06/14/dcterms#Standard](dct:Standard) entities which can either be Base Specifications (a standard not profiling any other Standard) or Profiles (Standards which do profile others). Base Specifications or Profiles can have Resource Descriptors associated with them that defines implementing rules for the it. Resource Descriptors must indicate the role they play (to guide, to validate etc.) and the formalism they adhere to (dct:format) to allow for content negotiation. A vocabulary of Resource Roles are provided alongside this vocabulary but that list is extensible. @en
