Classes
| Term | Label | Definition |
|---|---|---|
cg:Citation | Citation | A statement that a source is evidence for (part of) a map feature. In the direct JSON-LD reading of a Cited GeoJSON file every element of a feature's `citations` is a cg:Citation. When the citation locates a passage (selectors into a checksummed file) it is converted to an orp:Mention; otherwise it is converted to an orp:attestedIn link from the feature to the source. |
