XCend is a technology to specify and use hierarchical data structures. It is independent of any language or datatype paradigm, but - by using language dependent backends - code can be generated for various languages.

The major benefit of XCend is the addition of integrity constraints to hierarchical data structures, which makes a XCend type more than the sum of its parts. The XCend technology then helps you in theoretically ensuring your data stays valid, but will also give you the ability to practically work with and manipulate your data nevertheless. At the moment we are working on the STAT System, which is a handcrafted example system.

You can also take a look at the XCend File Syntax reference.
