GeoJSON is a format for encoding data about geographic features using JavaScript Object Notation (JSON) [RFC7159]. Geographic features need not be physical things; any thing with properties that are bounded in space may be considered a feature. GeoJSON provides a means of representing both the properties and spatial extent of features.

The GeoJSON format specification was published at http://geojson.org in 2008. GeoJSON today plays an important and growing role in many spatial databases, web APIs, and open data platforms. Consequently the implementers increasingly demand formal standardization, improvements in the specification, guidance on extensibility, and the means to utilize larger GeoJSON datasets.

This WG will work on a GeoJSON Format RFC that specifies the format more precisely, serves as a better guide for implementers, and improves extensibility of the format. The work will start from an Internet-Draft written by the original GeoJSON authors: draft-butler-geojson [1].

This WG will work on GeoJSON mappings of 'geo' URIs, reinforcing the use of RFC 5870.

This WG will work on a format for a streamable sequence of GeoJSON texts based on RFC 7464 to address the difficulties in serializing very large sequences of features or feature sequences of indeterminate length.

GeoJSON objects represent geographic features only and do not specify associations between geographic features and particular devices, users, or facilities. Any association with a particular device, user, or facility requires another protocol. As such, a GeoJSON object does not fit the "Location Information" definition according to Section 5.2 of RFC 3693, because there is not necessarily a "Device" involved. Because there is also no way to specify the identity of a "Target" within the confines of a GeoJSON object, it also does not fit the specification of a "Location Object" (Section 5.2 of RFC 3693, Section 3.2 of RFC 6280). When a GeoJSON object is used in a context where it identifies the location of a Target, it becomes subject to the architectural, security, and privacy considerations in RFC 6280. The application of those considerations is specific to protocols that make use of GeoJSON objects and is out of scope for the GeoJSON WG. As the WG considers extensibility it will be careful not to preclude extensions that would allow GeoJSON objects to become location objects unless the group determines such extensibility would be harmful. 

Deliverables:

* A GeoJSON format specification document including mappings of 'geo' URIs 
* A document describing a format for a streamable sequence of GeoJSON texts
