Media type name: application

Media subtype name: vnd.geovirtuallis.geov+zip

Required parameters: N/A

Optional parameters: N/A

Encoding considerations: binary

Inner archive members (project.json, layers/*.geojson) are UTF-8 JSON; the .geov envelope is a ZIP archive.

Security considerations: Data-only ZIP package (UTF-8 JSON + GeoJSON). No executable or active content. Importers should limit ZIP expansion (entry count, size, compression ratio), parse JSON safely, and treat all strings as untrusted. May contain sensitive location/attribute data; protect storage and transport as needed. ZIP decompression risks apply; see RFC 7230 / common ZIP-bomb mitigations. No fragment or external-link interpretation required beyond the published spec.

Interoperability considerations: ZIP is portable across OSes. Inner GeoJSON follows RFC 7946 (lon, lat). JSON is UTF-8. project.json version field defines descriptor semantics; unknown ZIP entries and JSON keys should be ignored.
