--- title: "Publication: Data & licensing | Nexus Observatory" description: "Publication, inside Data & licensing: OGC SensorThings API, OGC API - Connected Systems, observation models and ontologies…" url: https://observatory.global/data-products/publication/ publisher: Nexus Observatory Inc. updated: 2026-10-27 --- [Nexus Observatory](https://observatory.global/) / [Data & licensing](https://observatory.global/data-products/) / **Publication** # Routes from licensed to open release. Publication, inside Data & licensing: OGC SensorThings API, OGC API - Connected Systems, observation models and ontologies, OPC UA information models and more. Every item is traced to its specification, from OGC SensorThings API Part 1 (Sensing) 1.1 to OGC SensorThings API Part 2 (Tasking Core), and runs on the open Observatory Protocol. [Plan with us](https://observatory.global/contact/) Architecture [The protocol](https://observatory.global/protocol/specification/) **Technologies**: 9 **At the frontier**: 0 **Protocol functions**: 3 of 8 **Industries served**: 19 Reference design, drawn to scale · drag to turn · hover a part **01** What it is ## Open standards and interoperability. How observations move from the edge into stores, catalogues and APIs with their provenance, licence and residency attached, and how they interoperate through open standards and the open Observatory Protocol. Each technology below carries what it is, what we do with it, and the standard it is drawn against. Data, software and interoperability ### OGC SensorThings API Open API for things, sensors, datastreams and observations, plus tasking. We design, integrate and operate. OGC SensorThings API Part 1 (Sensing) 1.1 · OGC SensorThings API Part 2 (Tasking Core) Data, software and interoperability ### OGC API - Connected Systems System, deployment, procedure and datastream resources with commands, built on OGC API - Features. We design, integrate and operate. OGC API - Connected Systems Part 1 (Feature Resources) · Part 2 (Dynamic Data) Data, software and interoperability ### Observation models and ontologies The conceptual model and semantic web ontology for observations and samples. We design. ISO 19156:2023 (observations, measurements and samples) · W3C/OGC SOSA/SSN Data, software and interoperability ### OPC UA information models Industrial information models and companion specifications for equipment data. We design and integrate. IEC 62541 series · OPC UA companion specifications Data, software and interoperability ### Context information management Linked-data APIs for entities and their context in cities and infrastructure. We integrate. ETSI GS CIM 009 (NGSI-LD API) Data, software and interoperability ### Asset administration shell Standard digital representation of an industrial asset and its submodels. We integrate. IEC 63278-1 (asset administration shell structure) Data, software and interoperability ### Hydro and met data encodings Agency encodings for water and weather data exchange. We integrate. OGC WaterML 2.0 · WMO BUFR (FM 94) Data, software and interoperability ### Node roles and profiles The roles a node can play and the profiles that bundle its capabilities. We design and integrate. Observatory Protocol specification (Nexus Consortium) Data, software and interoperability ### Enrolment and admission state machines The states a device and a provider move through, from manifest to admitted for scope. We design, integrate and operate. Observatory Protocol specification (Nexus Consortium) **02** Architecture ## Where it sits, and what it speaks. Publication draws on 1 domain and 8 layers of the spectrum; the highlighted layers carry this area. It speaks 3 of the protocol's 8 core functions. Ingest and streaming 8 Storage and data lakes 6 Metadata, provenance and catalogues 8 Open standards and interoperability 7 APIs and SDKs 7 Licensing, residency and governance 8 Digital twins and observability 7 Open protocol interfaces and federation 8 01**Join** Identity, attestation quote, signed policy. 02**Admit** Admitted for a stated scope, nothing wider. 03**Describe** What, where, how and by whom, with calibration. 04**Time** One clock across the grid, with its error bound. 05**Observe** Every value with quality and provenance. 06**Qualify** Tested against the specification, state on record. 07**Federate** Signed exchange across grids and trust domains. 08**Orchestrate** Software and configuration by signed plan. **03** On the grid ## Every site joins one observing grid. The open networks on the grid today, over real relief and the geodesic cells we count them into, filtered to the hydrology domain this area serves. A site built here enrols into the same grid. **04** In the field ## Where this runs, sector by sector. 5 deployment scenarios from the sector research that rely on publication.
