JSON-LD and GeoJSON
JSON-LD, a a JSON-based serialization for Linked Data, is finally a W3C Recommendation. I'd like to remind readers that dumpgj, the any-vectors-to-GeoJSON program that is distributed with Fiona, will optionally add JSON-LD contexts to GeoJSON files.
$ dumpgj --help usage: dumpgj [-h] [-d] [-n N] [--compact] [--encoding ENC] [--record-buffered] [--ignore-errors] [--use-ld-context] [--add-ld-context-item TERM=URI] infile [outfile] Serialize a file's records or description to GeoJSON positional arguments: infile input file name outfile output file name, defaults to stdout if omitted optional arguments: -h, --help show this help message and exit -d, --description serialize file's data description (schema) only -n N, --indent N indentation level in N number of chars --compact use compact separators (',', ':') --encoding ENC Specify encoding of the input file --record-buffered Economical buffering of writes at record, not collection (default), level --ignore-errors log errors but do not stop serialization --use-ld-context add a JSON-LD context to JSON output --add-ld-context-item TERM=URI map a term to a URI and add it to the output's JSON LD context
