We have "born digital" - now what about "born semantic"?
Adam Leadbetter

While much effort has been put in to creating and curating these digital data, there has been little work on using semantic mark up of data from the point of collection – what we term “born semantic”.
In this presentation we report on two efforts to expand this area: Qartod-to-OGC (Q2O) and SenseOCEAN. These projects have taken a common approach to “born semantic”:
- create or reuse appropriate controlled vocabularies, published to World Wide Web Commission (W3C) standards
- use standards from the Open Geospatial Consortium’s Sensor Web Enablement (SWE) initiative to describe instrument setup, deployment and/or outputs using terms from those controlled vocabularies
- embed URLs from the controlled vocabularies within the SWE documents in a "Linked Data" conformant approach
Q2O developed best practices examples of
- SensorML descriptions of Original Equipment Manufacturers’ metadata (model characteristics, capabilities, manufacturer contact, etc ...)
- set-up and deployment SensorML files; and data centre process-lineage
- using registered vocabularies to describe terms (including input, output, processes, parameters, quality control flags)
...
The sensor descriptions are being profiled in SensorML and the controlled vocabularies are being repurposed from those used within the European Commission SeaDataNet project and published on the community standard NERC Vocabulary Server.
