How long does it take for rich snippets to appear?

How long should it take for my RDFa markup to appear in search results as a Rich Snippet after completing the submission form?

what is RDFa markup

This video should be removed and upload a new one. It's basically ancient news given the speed of web technology.

My snippet has been showing and still is showing on my older blog, but recently (almost a month) no. I tried to follow the Webmaster's guidelines for troubleshooting, but failed to restore it. Also, all my sites are verified. I'm not aware of anything I've done differently for this to happen. How can I restore it?

Someone should make a tutorial video walking through all the aspects of getting this process from start to finish. Many of us are "challenged" , (some more than others). I have read so much about it but I can't get my head wrapped around the whole thing...

Where is the form to submit a webpage?

Google added the snipps to my entire site of 20,000 plus pages. They were there in force for about 2 days and have slowly been automatically removed. Which is very weird and not weird on my part, hint hint Google

RDFa markup is a way to enhance your content with semantic meaning ;-)

Or, It's a way to tell Google what a particular bit of content is about. e.g. "this is my address", "this is my business name" or "this is a review".

You add RDFa to your html with extra tags and attributes.

I've had RDFa on my website for over 6 months, it validates and I've submitted it to Google. Still no sign of the rich snippets :-(

Is RDFa supported in all regions or just a select few at this time?

Looking forward to Rich Snippet coded hReviews being added to Google Places in the next few months.

Did you submit the notification form, as well? If the markup tested satisfactorily, it shouldn't take more than two months, maximum, for snippets to show up. However, if you did submit, but your submission had any complicating factors, such as any hidden text, that could be the reason. I suggest you contact Google and query them on it, just in case there's an issue with your submission.

Might be an idea to explain what an RDFa markup is first to compensate for the rest of us who are not so techinally adept
