Open and share-alike licences count for premium datasets

Changes since 2.40.0.

#Improved

• More licences qualify for premium datasets. A premium Orion dataset needs an open licence, from the publisher and from the boundaries it is drawn on. Two more kinds now count, in every country:

  • "Other (Open)", which many statistics portals use;
  • share-alike licences such as CC BY-SA and ODbL.

  Non-commercial licences and licences OrionGIS can't recognise still don't count.

• Boundaries under a share-alike licence can be used. The boundary finder now lists share-alike sets as usable instead of "to replace". It still flags sets with non-commercial or unknown licences.

#Credit and labelling

• Every row of a mapped table, on a map or in a download, carries the boundary set's credit and licence (loc_boundary_credit, loc_boundary_licence).
• A download drawn on a share-alike set also says so in its response (X-Boundary-Licence, X-Boundary-Credit).
• The ISO metadata's lineage names the boundaries' licence.
