Mission: The everyday programming and maintenance activities make use of knowledge about programming-related technologies such as graphical interfaces (GUIs), communication, security or XML. Having this knowledge in a machine processable form would enable new software analyses and raise the abstraction level at which the current analyses are performed. This page contains a repository of ontologies that share knowledge about programming technologies. Our approach for building these ontologies is described here. More informations about the context and target of our work can be found here.

FAQ

• How are the ontologies built?
  • We build the ontologies by analyzing the commonalities of several domain specific APIs that address the same domain. We manually did a post-processing step in order to eliminate the noise. For more details please see our paper: "Extracting Domain Ontologies from Domain Specific APIs" by Daniel Ratiu, Martin Feilkas, Jan Juerjens, (CSMR '08) pdf
• How can I contribute?
  • In order to increase the domain coverage we are interested in analyzing more APIs, especially from different programming platforms that those that are listed above (i.e. Java and .Net). If you have the technology to parse such APIs and you are willing to contribute please contact us.
• How can I use the ontologies?
  • The ontologies are under the LGPL license and thereby you are free to downalod and use them in any application you want. We would be glad to hear of their usage and to get some feedback from you.
