First real-life application of Wandora, built early 2000, was virtual art gallery Kiasmart consisting of digital art images, videos and text information snippets. Since then Wandora has been applied and developed in many real-life projects. Thinking the project history it looks like Wandora and topic maps suits well for publishing projects where existing database and document repository is made available for large audience. Analyzing the project history further reveals typical project structure:
- Design conversion process from the existing database to topic maps.
- Polish and spice up the generated topic map with some extra data and knowledge snippets.
- Design visual look for the service and implement templates for the look.
These are of course only our observations and may have only limited relevance in general but they may serve as a starting point for people thinking topic maps as an option for their own knowledge project. Lets examine Wandora's project history more detailed.
Kiasmart was first Wandora application project started 1999 and finished 2001. Kiasmart's motivation was to promote art collections of Museum of Contemporary Art Kiasma. Kiasmart was a client-server application where server built topic map daily using Kiasma's internal databases and image repository. Perhaps the most interesting feature of Kiasmart was this process of building topic map dynamically using metadata in images. Below is two illustrations describing the data harvesting process and general architecture of Kiasmart.
Arppeanet was our second Wandora project started 2001 and finished 2003. Arppeanet was a client-server application used to exhibit
- A register of Helsinki University officials from 1700 century to early 1900 century.
- Image collection of Helsinki University museum.
- Contemporary study options and study fields of Helsinki University.
Arppeanet's application framework was a direct descendant of Kiasmart. During the Arppeanet project our crossplatform framework PIP/GAF was integrated to Wandora. Integration enabled the service to produce more general representations of the topic map.
Perhaps the most interesting feature learnt in Arppeanet project was efficient knowledge extractions from loosely structured text fragments of Helsinki University official registry data using series of regular expressions. Here is an example of single registry record.
AEJMELÆUS Sanfrid August, yliop. asiamies. * Paltamo 4.2.1845 † Helsinki 13.7.1918, vanht khra Karl Aejmelæus ja Maria Karolina Thodén. Yo (pohj.) Vaasan luk. 66. Kamt 70, Tuomt 71.

The registry entry contains information about a single person. Information includes name, profession, birth time and place, death time and place, parents, education and career history, husband, and children. The extracted topic map of above entry can be found here. The topic map contains also all topic types and roles. The base name language of the topic map is Finnish.
Mediateekki & Media Archive
Mediatekki and Media Archive are WWW sites to promote video art collections of Contemporary Art Museum Kiasma. Media Archive is targeted for internal and research use. Mediateekki is targeted for larger audience and has much limited video base than the Media Archive.
The publishing patterns of Mediateekki and Media Archve are similar to Kiasmart described above. The data already exists in FileMaker database and is converted frequently to a topic map, and finally published using Piccolo-Wandora combination. The system generates new topic map daily and is always up to date. Here the technological issue was how to generate a topic map from FileMaker database. We tried JDBC bridge first but the FileMaker driver didn't work with poorly structured database and we had to think something else. Finally the problem was solved with HTML table dumps. It may sound little awkward but the solution worked very well. The idea was that FileMaker exports daily four large HTML files containing each a database table. These HTML files are then fetched by the Media Archive and converted to a topic map. This Media Archive topic map was then filtered resulting a smaller topic map for Mediateekki. And finally both topic maps were placed to a Wandora-Piccolo web application generating HTML visualisations using the topic map and predefined HTML template files.
