## py-thesaurus-interface An interface to metadata vocabularies for geospatial and other geophysical data
## Install ` pip install https://github.com/nansencenter/py-thesaurus-interface/archive/master.tar.gz ` ## Usage ` import pythesint as pti pti.get_gcmd_instrument('MERIS') pti.get_gcmd_platform('ENVISAT') pti.get_gcmd_provider('NERSC') `
The package follows the standards defined at NASA’s Global Change Master Directory (GCMD) (http://gcmd.gsfc.nasa.gov) and the NetCDF-CF conventions (http://cfconventions.org/), plus possibly others that will be added as needs emerge… The standards are mapped in Python dictionaries and saved to json-files.
## Directory Interchange Format (DIF)
The DIF format is a descriptive and standardized format for exchanging information about scientific data sets. The py-thesaurus-interface package provides an interface to the keywords and formats defined at GCMD.
