Triplr. Ultra simple GET-based web service for converting RSS / Atom / RDF / Microformats+GRDDL to HTML / ntriples / RDF / RSS / JSON / Turtle. Small pieces, loosely joined. # 30th March 2007, 3:30 pm

JSON and JSON-RPC for Erlang. Nice example of using lists:reverse and an accumulator to efficiently build a string in reverse order. # 25th March 2007, 4:29 pm
