Hi Alessio,
I understand that you are looking for a tutorial on how to implement a OSLC provider from scratch. This tutorial should not be technical but oriented a level just above, that's it aimed at managers or software architects.
I think the material listed by Nils is relevant. The article that would be close to what you are looking for is the OSLC tutorial and in particular the following page which describes how to plan a successful implementation of an OSLC provider: http://open-services.net/resources/tutorials/integrating-products-with-oslc/implementing-an-oslc-provider/planning-out-a-partial-implementation-of-oslc-cm/.
I think this article covers well the different steps you need to ask yourself before writing some source code:
- What is the business scenario to cover?
- What kind of tools do you want to add capabilities to?
- Which resources do you need to expose?
- What approaches to implement the provider are possible (i.e.: native, plugin, adapter)?
Good luck for your implementation,
Roch
