I am building a simple web tool for a client. It will query a database and display some data. They will be able to search, sort, etc., so a simple javascript tool can handle the display. I want to use perl on the back end, as I have done in other situations. It has been suggested that I implement it via REST and then I can add new features fairly easily (this client likes to request that).

I've read modern ways of doing web services. I've also read Apache2::REST. I don't see many servers using the latter, even though it looks good. Is something better? I don't want to do it all from scratch, of course.
