Hi, STON - Smalltalk Object Notation is a lightweight text-based, human-readable data interchange format for class-based object-oriented languages like Smalltalk. It can be used to serialize domain level objects, either for persistency or network transport. As its name suggests, it is based on JSON (Javascript Object Notation). It adds symbols as a primitive value, class tags for object values and references. Please read the paper here: https://github.com/svenvc/ston/blob/master/ston-paper.md The project lives here: https://github.com/svenvc/ston The code can be found here as well: http://ss3.gemstone.com/ss/STON This implementation works on Pharo 1.3, 1.4 and 2.0 as well as on Squeak. Last week Dale Henrich helped me get started with filetree/git (https://github.com/dalehenrich/filetree) and I like it. Check it out! He also ported STON to Gemstone, and is working on Amber and Cuis ports (https://github.com/dalehenrich/ston). Enjoy, Sven -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill
