Hi Marco,
Creating and updating a wiki involves various steps typically for example publish using EPF Composer, zip the publish, upload to server, create baseline process and use it to update the wiki.
It is possible to automate the whole process, so to auto publish and deploy content as engineers commit changes to process content that is under version control. I have done just that recently for two projects, one using RMC and one using EPF. But this is not a trivial step. I don't have clear cut recipe start to finish because it depends on many things.
It typically takes me a few days to setup a complete process engineering infrastructure including deployment server, version control, auto deployment, statistics, search. Just to give you one single example: EPF does not integrate with SVN for version control out-of-the-box. The integration can be done but this is not terribly straightforward or documented. There are many things like this along the way to the ideal process engineering infrastructure.
Best Regards,
Onno
