Several Earth sciences communities are defining new netCDF conventions for describing the semantics relating to their different domains. As the concurrent use of multiple netCDF conventions spreads, the problem of finding a common mechanism to validate and interpret metadata embedded inside netCDF files grows. OGC Encoding Linked Data Graphs in netCDF Files Standard (netCDF-LD) offers a solution to that problem.
The netCDF-LD is an approach for constructing linked data descriptions using the metadata and structures found in netCDF files. It is a format for encoding array-oriented scientific data, particularly in many Earth & Space Science domains.
To aid interoperability of netCDF files in Earth sciences, it is common practice to use the Climate and Forecasting (CF) convention and the Attribute Convention for Data Discovery (ACDD). Publishing netCDF file descriptions using linked data methods presents the user community with an opportunity to benefit from linked data’s improved exposure and connection. This, in turn, makes published data more Findable, Accessible, Interoperable, and Re-usable (FAIR).
Consequently, the Open Geospatial Consortium (OGC) seeks public comment due by June 24, 2022, on the netCDF-LD.
