While I agree with all the statements about community based development with Sourceforge, I must say that this approach has been tried unsuccessfully in different sets of activities that I have been participating in the past. The main problem with this is the following: source versioning systems are focused on detecting changes/deltas in source code, but not in ontology code. When a person makes a change in an ontology with an ontology editor, the most important fact is that the serialization of the ontology may be **completely different** to the previous one, in terms of the ordering of the RDF triples that appear in the file, what makes tracking of changes almost impossible for humans. > > I think that Raúl was commenting the possibility of using WebProtégé, which allows discussions over ontology terms, and probably we could go for a mixture of technologies/approaches: WebProtégé for the collaboration part on pure ontology development, and sourceforge for the bug tracking, the community involvement, and the releases of specific versions of the ontologies. > > What do you think? > > Oscar > > -----Mensaje original----- > De: public-xg-ssn-request@w3.org [mailto:public-xg-ssn-request@w3.org] En nombre de Krzysztof Janowicz > Enviado el: jueves, 16 de julio de 2009 8:44 > Para: public-xg-ssn@w3.org > Asunto: Re: SSN-XG Meeting Minutes 15-July-2009 > > Hi, > > >> Also, I like the idea presented in today's meeting regarding posting >> the ontology to a popular forum such as sourceforge.net using an open >> license (e.g. Apache/BSD variant) once a suitable baseline is available. >> > Thanks, there are basically three reasons why I brought this up > yesterday. first, a platform such as sourceforge offers us a very useful > architecture. we can develop the sensor (and observation) ontology > together using SVN as versioning system and hence document our design > decisions (and that is what ontology is about). somebody like holger > could act as release manager and make official releases every x weeks. > on one side, this would give as some regular schedule (and pressure) to > make our recent changes coherent. on the other side, interested people > can always browse the SVN at sourceforge directly to see what is > happening right now. moreover, sourceforge offers a forum, a bug > tracker, and especially also a feature request form. we can use these > features to coordinate our work on the ontology but also to get feedback > from others. second, if we host the ontology (no matter in which stage) > at sourceforge people will start to use it and give us feedback. this is > also about transparency - having the ontology only on our wiki makes it > difficult for others to find out who is responsible for which parts, who > should be contacted, and so on. third, IMO the licensing issue is an > important decision. everybody should be free to use the ontology and to > modify (fork) it if necessary (especially because our work is also based > on other ontologies). finally, having it at a platform like sourceforge > makes sure that work on the ontology can also continue (and be supported > by others) after the incubator group ran out. > > Best regards, > Krzysztof > > > Kelsey, William D schrieb: > >> Hi All, >> >> >> >> I'm new to the group (today was my second meeting).
