Hey folks,

There is now a live, Web-based JSON-LD processor available here:


It uses the latest experimental JavaScript JSON-LD processor (Forge's
JSON-LD processor) written by Dave Longley. The processor includes some
of the latest changes we've been discussing on the mailing list. "@" is
now "@subject". "a" is now "@type".

It also implements the latest normalization algorithm that Dave's been
working on, which he will explain in a separate e-mail. The new
normalization algorithm works with all of the known, really nasty graph
isomorphism inputs that the old algorithm didn't handle. At present, we
do not know of a single case that the algorithm cannot handle.

The website also got a bit of a facelift. Not much of one since I'm no
graphic designer and my CSS skills are fairly lame.

The biggest addition is the Playground code, which allows you to:

1. Type out arbitrary JSON-LD and view it in compact form,
   expanded form, normalized form, framed form and as TURTLE.
2. Specify a JSON-LD frame to re-frame an arbitrary set of triples
   into a JSON data structure.
3. Select a set of pre-made JSON-LD examples and view the output.
4. Immediate feedback on the output of the JSON-LD processor.
5. Syntax highlighting for JSON-LD and TURTLE, making it easier to
   spot and debug errors.
6. Very minimal error handling - need to integrate a JSON linter at
   some point.

Give it a shot and let us know what you think of it. All code for the
site and the playground is available here:
