David Damen of SpaceApps has checked in the first version of Tropics, the RESTful web service API to Ontopia discussed here earlier.

Lars Marius Garshol wrote a short blog posting outlining how SDShare works and what it can be used for. This might be useful reading for those wondering what the Ontopia SDShare implementation is good for.
Note that the SDShare implementation in Ontopia has now been extended with a client web application making it easy to pull changes from remote topic maps.

Let’s imagine that you are making a map of pubs, as some of us do. The geographical location of a pubs is a very important piece of information to attach to it, so let’s do that.

This is the correct location, so we just click “Set position” at the bottom, and are done. Alternatively, you can click anywhere on the map to set a different position. After clicking “Set position” you come back to the topic, with the coordinates set, as shown below:
