Georss - Geographically Encoded Objects for rss Feeds

Georss is an emerging standard for encoding location as part of a web feed's (aka "channels") standard functionality. Georss is derived from encoding location, and rss, the mose widely known web feed and syndication format.

Georss's location content consists of geographical points, lines, and polygons of interest and related feature descriptions. Georss feeds are designed to be consumed by geographic software such as map generators, and by creating these encodings on a common information model, the Georss collaboration is promoting interoperability, as well as upwards-compatiblity across encodings.

Georss Simple

The Simple serialization of Georss is designed to be maximally concise, in both representation and conception. Each of the four Georss objects require only a single tag.

This simplicity comes at the cost of direct upward compatibility with gml. However, it is straightforward to devise transformations from this Simple serialization to the gml serialization through the gml model. For many needs, GeoRSS Simple will be sufficient.

Some publishers and users may prefer to seperate lat/long pairs by a comma rather than whitespace. This is permissible in Simple; GeoRSS parsers should just treat commas as whitespace.

Georss gml

Geography Markup Language is an xml grammar written in xml Schema for the modelling, transport, and storage of geographic information...gml provides a variety of objects for describing geography including features, coordinate reference systems, geogmetr, topology, time, units oof measure, and generalized values. A geographic feature is "an abstraction of a real world phenomenon; it is a geographic feature if it is associated with a location relative to the Earth? (there question mark in the docs, not mine!)
