Right, I'm pleased to say that I've now implemented enough of the Fjord language on Node.js to be able to run the Instrument example that I introduced it with. As yet, this runs in memory only - i.e., no disk, no network.

Here's the code on GitHub with tests that show how it works. The language has changed a little so I'll show the example here again, copied over from the test code, in order to explain the differences.   ...

Well, I've put together the first few lines of Fjord, implemented on Node.js.

Here's the description on GitHub: Fjord is a language for expressing domain logic as match-rewrite functions over mashable JSON Web objects.

I'm developing Fjord very openly, in the hope someone out there will be interested in getting involved in helping guide its design and implementation. I suppose code speaks louder than blog posts.   ...

Following on from my recent article where I derived FOREST, this article offers the beginnings of a JSON unification and rewriting language that can be used in a FOREST architecture.

Why JSON, not XHTML, now? Well, I recently discovered that JSON is overtaking XHTML in interest, and I was further inspired by Kris Zyp's recent announcement of his JSON Schema Internet-Draft.

Fjord is a language for describing how the state of a JSON resource at any time depends on both its current state and on the state of other JSON resources that it links to via hyperlinks.

Fjord is a Norwegian word, probably pronounced 'fiyourd', and might stand for some combination of the words: 'Functional JSON Object/Observer Resource/Rule/Rewrite Dependencies/Declarations'. Or maybe it's just because they're truly awesome, an' I wanna go.

Fjord also gives me an opportunity to show some examples of the "end-user" view of a FOREST interaction; starting with a simple finance example.   ...
