Description

The REC core module collects the top-level classes and properties that span over or are reused within multiple REC modules.

Note that this module reuses certain classes, properties, and named individuals from other vocabularies, e.g., GeoSPARQL; the copyright conditions on those reused entities are stated in their respective rdfs:comments annotations.

Classes

Geometryc # Classes

URI http://www.opengis.net/ont/geosparql#Geometry
Is Defined By http://www.opengis.net/ont/geosparql#
Description

The class represents the top-level geometry type. This class is equivalent to the UML class GM_Object defined in ISO 19107, and it is superclass of all geometry types.

GeoSPARQL is Copyright (c) 2012 Open Geospatial Consortium, Inc. All Rights Reserved. http://www.opengeospatial.org/ogc/document.

Actuatorc # Classes

URI https://w3id.org/rec/core/Actuator
Description

An actuator takes some control input and executes some real-world action based on this input. Examples include setting dampers/valves in heating/cooling systems at certain configurations, opening or closing a smart lock, turning on or off an electric radiator, etc. REC does not provide semantics for every type of actuator you might find in a building; rather we here provide classes and properties that allows users to define their own actuator models, based on the systems they have, adhering to REC.

Agentc # Classes

URI https://w3id.org/rec/core/Agent
Description

The human, group, or machine that consumes or acts upon an object or data. This higher-level grouping allows properties that are shared among its subclasses (Person, Organization, Company, Department...) to be anchored in one joint place, on the Agent class.

Campusc # Classes

URI https://w3id.org/rec/core/Campus
Description

A campus represents a collection of location entities. The constituent locations may have differing legal ownership and utilization purposes, but they are generally perceived as a coherent unit or sub-region within a city or other region. E.g., a university campus, a hospital campus, a corporate campus, etc.

Capabilityc # Classes

URI https://w3id.org/rec/core/Capability
Description

A Capability indicates the capacity of an entity, be it a Space, an Asset, or a Device, to produce or ingest data. This is roughly equivalent to the established Brick Schema and generic BMS term "point". Specific subclasses specialize this behaviour: Sensor entities harvest data from the real world, Actuator entities accept commands from a digital twin platform, and Parameter entities configure some capability or system.

An administrative grouping of entities that are adressed and treated as a unit for some purpose.

Devicec # Classes

URI https://w3id.org/rec/core/Device
Description

A thing made or adapted for a particular purpose, specifically a piece of electronic equipment. A Device can contain subdevices or be part of superdevices. It is subclassed into more specific device types, e.g., Sensor, Actuator, etc.

Deprecated in favour of core:Asset (the hardware), core:LogicalDevice (the software), and core:Capability (the measurement or actuation capability).

Eventc # Classes

URI https://w3id.org/rec/core/Event
Description

A spatiotemporally indexed entity with participants (e.g., something which occurs somewhere, and that has or takes some time). We do not on this top level define the particulars of how to model space or time; that is left to the implementing subclasses. Thus, in a sense, this is just a cognitive clustering for human consumers of the ontology, a root class from which all different types of events derive.

Description

A piece of equipment or software that communicates and interacts with a digital twin platform. Could, e.g., be an integrated circuit inside of a smart HVAC unit, or a virtual server running on a Kubernetes cluster. Logical devices can have Capability instances (through hasCapability) that describe their input/output capabilties. If Logical Devices are embedded within Asset entities (through the locatedIn property) such capabilties typically denote the capabilities of the asset.
