RFC 5870: “A Uniform Resource Identifier for Geographic Locations”

June 7th, 2010 by alex Leave a reply »

It’s Done.

RFC 5870 (“A Uniform Resource Identifier for Geographic Locations”) has finally been published by the Internet Engineering Task Force as “Proposed Standard”. The RFC contains the final, stable and approved IETF specification of the “geo” URI scheme – the 23 pages document is the result of 3 years of hard work, several presentations at IETF meetings, hundreds of email conversations about protocol details, discussing the proposal again and again, and – finally – interacting with not just one, but two sets of Area Directors in the IESG (Approval was perfectly timed with the end of the term of several Area Directors, so it had to be reviewed by the incoming IESG members as well).

Now that the “blueprint” part of the URI scheme is done, we’re looking forward to applications actually using the “geo” scheme (besides the ones we know of already). The URI scheme will also very likely see adoption in other IETF documents. If you know of an application that you think should support the “geo” URI scheme – let us know.



  1. Do you plan to upgrade the Firefox extension,which no longer works with recent (3.0.6) Firefoxes?

  2. alex says:


    yes, i plan to do so. I will actually re-implement it from scratch when i have time. Unless someone else does integrate support for the URI scheme into Firefox’ main source 😉

    Please feel free to improve it!

    As a Surveying Engineer, I have a lot of comments to do, due to serious concepts mismatches. How can I submit the comments to fix and enhance this document?

  5. Alex says:

    Hello Ivanildo,

    from the IETF perspective, this document is finished, and “done”. Hence, there are no changes possible to the document anymore (there was a 3-year review and discussion period before it was published). However, there are still two options to discuss your comments:

    1) You can send your comments in email to the GEOPRIV working group discussion list (geopriv@ietf.org) – If you want, you can also send me the comments privately, i would be very interested in them.

    2) You can – if you think the document contains major flaws – submit an “Errata” to the RFC Editors – this is described here:
