GeoRSS
GeoRSS is nothing more than regular RSS with x and y coordinates. It is also integrated into OpenLayers, and creating a layer directly from the RSS feed is easy, and toggling on and off these layers is also fast and easy. Another thing OpenLayers does with GeoRSS is that it creates popups on click automatically, using the description and title elements in the feed. Another thing we are doing with GeoRSS is allowing other departments on campus access our data, while not giving them direct access to our database. We have set up different query parameters that dictate what information is returned. Specific building info, search results based on descriptions and tags, and even complete point layers. Using this they can create their own maps using the IT map server to serve up the base map tiles, and their own interface using OpenLayers, and GeoRSS to quickly and easily make their own web maps.
Another nifty thing we are using GeoRSS for is the ‘You are here’ layer. When folks are on campus we are able to use their IP address to make an educated guess as to what building they are in and then create a GeoRSS layer by getting a feed that has the x and y for that specific building. If we are unable to determine what building they are in the layer doesn’t show up at all.
