It would be great to see a standard emerge here. I've watched with interest as JSONPath and JSONQuery proposals have been presented, JS ports of Linq, and this latest proposal: RQL – http://www.sitepen.com/blog/2010/11/02/resource-query-language-a-query-language-for-the-web-nosql/ http://www.sitepen.com/blog/2010/11/02/resource-query-langua... There's an Arel-style JS implementation to build RQL strings using chained methods, which makes it quite conducive to composition and makes it feel more like functional programming. Along those lines are D3's selections: http://mbostock.github.com/d3/#selections ... and jLinq http://www.hugoware.net/Projects/jLinq
