Dear all,

I've requested that a WG be formed to standardize the GeoJSON format.
Comments are welcome on the dispatch list. I hope that you'll indicate your
interest in participating.

Dear all,

May I move that we start the GeoJSON WG using the charter below?

(Also forwarded to the geopriv list and to the original, not-IETF, geosjon

Proposed GeoJSON WG Charter


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.


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