Geographically Encoded Objects for RSS feeds

location based services

This site describes a number of ways to encode location in RSS feeds. As RSS becomes more and more prevalent as a way to publish and share information, it becomes increasingly important that location is described in an interoperable manner so that applications can request, aggregate, share and map geographically tagged feeds.

To avoid the fragmentation of language that has occured in RSS and other Web information encoding efforts, we have created this site to promote a relatively small number of encodings that meet the needs of a wide range of communities. By building these encodings on a common information model, we hope to promote interoperability and "upwards-compatibility" across encodings.

At this point we have completed work on two encodings which we are calling GeoRSS GML and GeoRSS Simple. GeoRSS GML is a formal GML Application Profile, and supports a greater range of features than Simple, notably coordinate reference systems other than WGS84 latitude/longitude. It is designed for use with Atom 1.0, RSS 2.0 and RSS 1.0, although it can be used just as easily in non-RSS XML encodings. GeoRSS Simple has greater brevity, but also has limited extensibility. It can be used in all the same ways and places as GeoRSS GML.

Finally, if you've come here simply looking for a way to encode a point in XML, use either the 'GML' or 'Simple' version:

Simple

GML
