You obviously maintain a CSDL parser - is that code you are willing to release?
Shame. The more tools that support CSDL the more Datasift stands to benefit as the only provider of content that happens to use this language.
There is a CSDL syntax and validation plugin for Sublime Text which lists all our current targets and operators - https://github.com/lukashed/datasift-sublime-text
OK, thanks. The grammar file may be a useful start-point for re-creating a parser.
