Ontopia 5.1.2 is released

We have just released Ontopia 5.1.2. This release includes three Ontopoly bug-fixes. Download it here.


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:

Geotagging a pub #2

An Ontopia/Joomla integration

At TMRA 2010 a team of Czech researchers at the University of Economics in Prague presented their integration of Ontopia with the Joomla! CMS. Joomla is written in PHP, so they used the TMRAP web service to invoke tolog queries on the Ontopia server, and then present the results with XSLT. They have a UI for managing this, and even a framework for building user-friendly tolog query builders.

For more information, see the presentation page, which has the full paper and the slides. (Later, it will also have a video of the presentation.)

David Damen becomes a committer


David Damen presenting Tropics


David Damen of Space Applications Services became an Ontopia committer today. David has been an active member of the Topic Maps community for a while, and right now he is working on Tropics, a web service interface to Ontopia, which he intends to add to the Ontopia sandbox in the near future. (He is on holiday at the moment, so it may take a while yet.)

We will return with more information on Tropics in the near future.
