Re: Template language for SPARQL?

Hi David 

Thanks to Paul for mentioning our blog post from a few weeks ago. We felt the same need as you and set up a simple approach to substitute URL parameters into a sparql query. We've found it very handy. 

If something like this was included in the standards then we'd be happy to adapt to follow that standard.
