Geolocation Working Group Overview

The mission of the Geolocation Working Group, part of the Ubiquitous Web Applications Activity, is to define a secure and privacy-sensitive interface for using client-side location information in location-aware Web applications. The Working Group meets regularly by phone and has two to three Face-to-Face meetings per year.


The Geolocation Working Group Charter details what the W3C has tasked this Working Group to do.

Members should join the Geolocation Working Group.


Note: This table will be updated periodically as the Working Group identifies new milestones.

How to Participate

Members should join the Geolocation Working Group, but we do our work in the public, mainly on the mailing lists.

The main mailing list for the Geolocation Working Group is: public-geolocation@w3.org. This list is open to the public and also has a public archive. To subscribe or unsubscribe please send mail to public-geolocation-request@w3.org with a subject line of subscribe or unsubscribe.

There is also an IRC channel dedicated to the Geolocation Working Group: #geolocation on the W3C IRC server: irc.w3.org:6665

In addition there is a member-only mailing list at member-geolocation@w3.org for administrative purposes. This list also has a member-only archive.

The Working Group maintains a Wiki with links to minutes from Face-to-Face meetings and teleconferences. In addition the group uses Tracker to maintain issue and action item lists.

Relationship with Other W3C Work

As listed in the Geolocation Working Group Charter, it is expected that we will be interacting with the following W3C Working Groups.

Device APIs Working Group
The DAP Working Group is responsible for other device APIs. DAP should review the Geolocation API documents in order to maintain consistency between Geolocation and other device APIs.
System Application Working Group
The System Application Working Group is responsible for developing other device APIs executed in a privileged environment. SysApps should review the Geolocation API documents to ensure they apply correctly in that environment.
Web Applications Working Group
The Web Applications Working Group is responsible for core Web APIs, and thus may provide valuable feedback on our documents. It also develops WebIDL which the Geolocation deliverables will rely on to define their interfaces
Technical Architecture Group
The TAG and participants in the Geolocation WG have discussed the privacy aspects of the Geolocation API v1, and will likely continue to do so going forward.
Privacy Interest Group (PING)
As sharing location information has a direct impact on users' privacy, the Geolocation WG intends to secure reviews on its deliverables from the Privacy Insterst Group to ensure they offer the right level of protection to users.
Web Security Interest Group
The Geolocation Working Group intends to secure reviews on its deliverables from the Web Security Interest Group to ensure they offer the right level of security.
Web Accessibility Initiative
The Geolocation Working Group expects to work directly with the Web Content Accessibility Guidelines (WCAG) Working Group to ensure that any accessibility implications inherent to this work have been taken into account and addressed.
