A new (?) contender in "useful + elegant path language for JSON": jPath
Ok now: there have been contenders (most notably JsonPath) for the title of "the JSON path". But so far it's still up for grabs -- none has gotten things quite right.
But it looks like there's now one more interesting take, JPath. Maybe it's just my new liking to jQuery, but this one seems to get the most important aspect (syntax!) right. For me at least, it all comes down to having expressive and elegant DSL to express simple path navigation. Will need to play with it a bit to see if things click like they should; looks like it'd be a natural with jQuery. If so, this might be just what we need.
