is there a scripting reference for InDesign

I have looked around or I would not be asking - is there an official scripting reference, such as what Adobe maintains online for Flash, that includes the complete object model for InDesign and how to access it? I have the advanced tutorial. I also visited niemannross.com per the wiki post, but have trouble accessing the site even with an openID.

If not official, what is the best alternative? (I did find http://www.indesignscriptingreference.com/cs3/javascript/ on the web - is that the best out there?)

Thank you!
