“Standards-based description of environmental sensor metadata, including provenance, is paramount to automated data discovery, access, archival, processing, as well as quality control and assessment.”
The X-DOMES pilot project leverages existing relationships with large NSF-funded data management programs, EarthCube building blocks and working groups, and environmental sensor manufacturers and consortia. The project seeks to establish a community of sensor manufacturers and other stakeholders to provide a unifying approach to describing sensors and observations across geo-science domains. Built on an existing sensor metadata model that references registered, standards-based vocabularies, the X-DOMES pilot project is providing a suite of tools, built upon community-adopted standards of the Open Geospatial Consortium (OGC) and World Wide Web Consortium (W3C) to demonstrate and facilitate the generation of metadata documents that are discoverable and accessible on-line and/or directly from on-board sensor descriptions. We also demonstrate mechanisms to associate the data with the metadata through standards-based web services. With vendor-ready tools implemented throughout a broad-based community, the X-DOMES Network has formed the foundation for the development of and adoption of interoperable access to much needed content-rich sensor metadata.

The ESIP Community Ontology Registry (COR) can be used to create resolvable links to key terms in describing sensors, such as sensorType, observableProperty, property, process, characteristic and capability. These are terms that can be referenced in SensorML documents.
The COR is available at: http://cor.esipfed.org/

The videos below discuss the ESIP COR. The X-DOMES ORR works the same way – but is a space where we recommend you build your sensor related ontologies (e.g., sensor types, observable properties, etc. ). If you feel it is necessary, the ORR software can be installed to create your own ontology management system (and branded with your own institutional label) and rehosted at the ESIP COR and/or the X-DOMES ORR.
