T Exchanging the Status between Clients of Geospatial Web Services and GIS applications using Atom

Today, the discovery and sharing of geospatial information over the Web presents some difficulties which have not yet been solved. News distribution through website content was simplified by the use of Really Simple Syndication (RSS) and Atom syndication formats. This paper exposes an extension of Atom to redistribute references to geospatial information in a Spatial Data Infrastructure distributed environment. A geospatial client can save the status of the application and share this status with other users that need to deal with the same information and use different client vendor products in an interoperable way. The extensibility of the Atom format was essential to define a format that could be used in RSS enabled web browser, Mass Market map viewers and emerging geospatial enable integrated clients that support Open Geospatial Consortium (OGC) services. The status exchange between a web client application and Geographic Information System desktop solution is demonstrated.
