Hi,

I thought about that and the only tool I know might be useful for that is Spring Framework AplicationContext (aka BeanFactory).

I feel like I’m missing some context here. Is this a reply intended as a comment on issue https://github.com/eclipse/rdf4j/issues/641 ? Or were you replying to some other specific mail and did that message get lost somehow?

As for your suggestion: my Spring is rusty but if using a BeanFactory helps make config more flexible I’m all for it. 

For me there is only one big pro:

- Simple but powerful XML syntax to define even complex solutions.

- Possibility to pre-loading values

- Possibility of usage factories

- The outcome is well and clean wrapped as used defined

cons:

- BeanFactory layer should be separated from the rest of the application. It is not difficult but might be tricky (see pros 2nd and 3rd). It might be necessary to wrap everything (factory + outcome) within borders to close possibility of creating some nasty monster for both server and putative users.

- I found spring framework is already in use so our ApplicationContext instance should not be linked with the rest of instances.

I can’t really comment on your analysis beyond that I think it sounds like you’ve got a solid approach in your head. If you have time to put a first draft design together that’d be great! 

That is my thoughts,

Best regards,

Jacek

PS I could not figure out where are located templates for RDF models which are passed to the main server's repository with values given by user or is that final RDF created dynamicaly by parser?

The templates are in src/main/resources in repository-api.
