Content of the presentation
Observatory in Hradec Králové View of the original application used at the
Observatory Topic Maps as the new solution
− Topic Maps document creation− Web presentation creation
Final state and future of the pilot application

Observatory in Hradec Králové
Science and research:− performing photometric observations of variable
stars and asteroids− astrometry of comets, study the dynamics of small
Solar system bodies Cultural program:
− observation of the Sun or evening performance− specialized scientific lecturers− systematic education

Topic Maps document creation
Development of the Topic Maps document (TMd) was realised in diploma thesis
One of the main goals: verification feasibility Topic Maps approach
Domain expert (final user) helped with keeping objective accuracy of information presented in TMd
Requirenments for the content of the TMd were specified ...
7
Requirenments for the TMd
User´s requirements PriorityCapturing the ontology of astronomical terms highTopics implementation highImplementation of associations among topics to enable navigation highExternal occurrences implementation mediumDefining internal occurrences mediumDefining topic names in different languages high

Resolution connected with usage of the TMd The 1st version of the TMd in editor Ontopoly
that fulfils most of the requirenments Resolution: Topic Maps and Ontopoly is very
suitable solution for the Observatory needs Practical usage of the TMd with OKS
Samplers for the pilot version Resolution of the next consultation: it is
better to have own web application Requirenments for the web application were
specified ...

Requirenments for the web application based on Topic Maps
User´s requirements PriorityIntuitive navigation highClear organization of web pages highPossibility to search Topic Maps elements highPossibility to visualize Topic Maps document in expandablegraph structure
high
Possibility to edit elements of the Topic Maps document fromweb-based forms
medium
Online presentation of the Topic Maps document high

Experience with Ontopoly
Ontopia Navigator Framework (ONF) was chosen for the web application creation
At the beginning only experiments with ONF One serious problem occured:
− Web pages created with ONF contain ID values of the Topic Maps elements. If we modify TMd in Ontopoly, ID values change => we have to change ID values in web pages almost all the time
Next step → searching more suitable tool for TMd creation
11
Next Topic Maps editors
Wandora, TMTab plugin, TM4L LTM syntax written in NotePad was tried too,
but this way is unsuitable for the customers TM4LTM4L editor was chosen because of:
− Intuitivenes in control over the environment− Low price− Installation with no sweat− Automated testing of web sources− And mainly: if we modify TMd, ID values of the Topic
Maps elements are steady
12
Next steps ...
Detection: TMd created in Ontopoly could be opened in TM4L (ver. 1, 2), but taxonomy was not saved
Solution: developing TMd once more in TM4L (ver. 2)
After some white nights, we came up to creating web application with ONF and TM4L ... :-):-)
13
Web presentation creation
Developing simple web pages with ONF lies in the use of the tolog query language
JSP web pages contain tolog queries that:− extract relevant information from the TMd− represent these information on the web pages
Firstly scope of the web had to be stated => only concepts related to selected objects of the Solar system were taken into account
Predefined layout was chosen and adjusted for our purposes ...

Evaluation and future of the web application Navigation scheme and organization of pages
are clear and easy to use It is possible to quickly detect association(s)
between topics

Concluding words ...
„The universe is a pretty big space. It's biggerthan anything anyone has ever dreamed ofbefore. So, if it's just us, seems like an awfulwaste of space, right?“
