JSON and Ajax
You are familiar with Ipedo's strong XML credentials, but some of my colleagues have recently done some very interesting work on an open source project supporting JSON, a competing/complementary data format. JSON (JavaScript Object Notation) is a light-weight and simple way to package information to be interpreted in a way that is very natural for JavaScript. The project I am referring to is called ChaiDB, a project on SourceForge. ChaiDB is a general purpose database library that allows applications to build embedded databases. In that way it is similar to BerkeleyDB.
The project also includes a sub-project, JSON-Cache, which is an application of ChaiDB. As the name suggests, this project implements a method to cache JSON objects. This could be particularly useful now that Ajax services are starting to take significant interest in JSON. Given that JSON is a less verbose, less type-stringent alternative is attractive to Ajax services which don't particularly need that capability of XML. The cache will be helpful for those implementors that need that extra boost to performance that JSON and JSON-cache will afford them. Be sure to check it out.
