Tropics added to Ontopia sandbox

David Damen of SpaceApps has checked in the first version of Tropics, the RESTful web service API to Ontopia discussed here earlier. The README file has build instructions, while more in-depth explanations can be found in the TMRA talk about Tropics. The design document describes the interface in more detail.

Why SDShare is useful

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.

Geotagging in Ontopoly

We thought it might be interesting to show off one of the new features in 5.1.1: geotagging.

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. We create two occurrence types, latitude and longitude, and give them the required PSIs. Once we’ve done that, the pub instance page looks like this:

Geotagging a pub #1

Note the little icon next to the latitude field. Clicking that will open a dialog window, as follows:

Geotagging dialog #1

If you now type in the address and click the “Search” button, and then zoom in, you see the following:

Geotagging a pub #2

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:
