Vmap test

[marqh]

a few bug fixes and a new test data set for valuemaps and mediators

@marqh please could you add the following missing prefixes to the test turtle data:

• concepts.ttl
  • @prefix dc: <http://purl.org/dc/terms/> .
  • @prefix gribapi: <http://def.ecmwf.int/api/grib/keys/> .
• mappings.ttl
  • @prefix dc: <http://purl.org/dc/terms/> .
  • @prefix xsd: <http://www.w3.org/2001/XMLSchema#> .

Otherwise it causes a tdbloader riot! :wink:

@marqh This is good to go :+1:

The static data contains:

• 116 cf to um mappings
• 487 um to cf mappings
• 66 cf to grib mappings
• 66 grib to cf mappings

The test static data contains:

• 0 cf to um mappings
• 1 um to cf mappings
• 2 cf to grib mappings
• 2 grib to cf mappings

... as expected! Thanks.
