JSON-LD context

glx-context.jsonld is the canonical JSON-LD @context for the GENEALOGIX archive format. It maps GLX entity types and common properties to Schema.org classes (Person, Event, Place, CreativeWork, ArchiveOrganization, MediaObject, GeoCoordinates, PostalAddress) and uses a glx: namespace for GLX-native concepts that Schema.org does not cover (Citation, Relationship, Assertion, Participation, VocabularyEntry).

This file is the source of truth. It is embedded into the go-glx library and inlined into every glx export --format jsonld output so emitted documents are self-contained — no network access required to resolve the context.

See issue #291 for the design discussion.
