Hi Andreas,
I used Stanbol, thought it was great, and got these ideas from it. The thing about it is that it’s a pretty heavy Java OSGI thing and I don’t know how someone would easily run that on their pod. You could have a separate Stanbol server that someone else maintains but then you really don’t know if you can rely on it or configure it the way you want. I think the content enhancement can be done in JavaScript so there is not an unknown server involved.
