Re: Declarative validation of recursive documents

[Roger Rohrbach]

See also Orderly, a really nice, terse syntax that compiles into JSON Schema.  
I've used it to specify the documents for a project using CouchDB.  The bad 
news is: the developer seems to have abandoned the project, while JSON Schema 
continues to evolve.  My attempts at engaging the developer have been met with 
silence.  The good news is: anyone can fork it on github and take it further.
