David Walsh of SitePen has authored a pair of articles this week about various Dojo-related topics:

• JSON Validation with JSON Schema discusses the general topic of JSON Schema, and how to use it for validation in general, with dojox.json.schema, and with CommonJS-Utils, part of Dojo Foundation project Persevere, on top of Node.js. JSON Schema is growing in popularity, for example, it’s used for Google Chrome’s extensions system.
• Generate Dojo GFX Drawings from SVG Files discusses exactly what the title says, a Dojo utility for converting SVG files to GFX format, and shows a nice SVG to GFX demo if you like the Arsenal. The October London Ajax video and web vector graphics slides also offer recent discussion around GFX.
