This is a terribly beginner series of questions, but after reading through a good 30 SPARQL tutorials I can't seem to wrap my head around what SPARQL is or how to begin using it.

Is it executed on the client side?
Is microsoft somehow going to be able to mess this up?
Can you use a common relational database (SQL)?
Are there particular resources you recommend over others for learning?
Do you feel it is premature to begin investing myself in this?
Best way to get set up and running to start tinkering?

The RDFA examples I have seen are very inspiring. I am currently a big proponent of using microformats but would really like to take it further. I currently develop in PHP, but have only found a Java library.

I've looked around but most books seem to fall into one of two categories: Either the book talks about SW technologies but doesn't teach you how to use them Or the book is geared for very complex data modeling and ontology creation. Worse, many of those books are outdated. I'm looking for an… >>> More
