Which Triplestore for rapid semantic web development?

Question

Ease of installation/use is the most important factor here - not performance.

Small is OK as large datasets are not expected.

Answer 1

I've been impressed with ARC2 as a PHP/MySQL offering. The project website has a helpful "Getting Started" to get you up and running quickly and questions/problems are addressed quickly on the mailing list. Depending on what you are trying to do, SPARQLscript, a mini-language add-on to ARC2 for processing query results may be very useful.
