I thought XEP 80 was complicated enough. :P I was planning to restrict the API to using WGS 84 for geographical coordinates. This implies that clients and connection managers may need to do conversion in some cases. I think having a latitute/longitude in WGS 84 covers the majority of use cases. Further use cases are probably covered by having room/street/city/province/country etc. key/value pairs. For more complicated cases, using extended presence or tubes may be more appropriate. -- Dafydd _______________________________________________ Telepathy mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/telepathy
