Patrick here, I work at Tableau and maintain the Tableau Community Forums as a Community Manager. First, sorry for the delayed reply.
Second, I would be happy to investigate any missing content from the forums, we have a fairly strict policy on deleting content and there is a possibility this content has merely been moved into our archive. I would be more than happy to resurrect or at least provide you access to if this is the case. Is there a link to the OP handy? maybe an old bookmark or blog post? I might be able to use some admin wizardy to investigate where it has gone.
Third, thank you for sharing this with the Community! The Tableau Extract API is a great place for this content.
I look forward to getting a link or title of the OP so I can hunt it down for you.
Hmmm, I didn't receive an email when to posted this and was only back because someone else asked a question regarding licensing.
It was originally posted in the Tableau 8 Beta section back when the API was brand new. There were a bunch of reply posts on it, and posts in other areas that linked to it. I think I hunted those all down and posted a link to my new post, so you might find one of those dead links if you search a bit, as I discarded my shortcut to it when I found it no longer worked.
I was asked what license I released this under ... oops, I forgot to include it when I had to repost, darn it.
Anyway, I'd used the MIT license. So feel free to you it as you will, just include a text file in your source code with:
