Hello Alex,
my name is Hans L....e and I am using your Chrome-Extension Green Turtle.
Thank you for that, it is the only scraper for RDFa 1.1 I found.
It's been running fine for a few days. But then suddenly it stopped extracting 
triples. First it stopped showing the graph, then it stopped showing the 
triples below. Very strange.
I un- and re-installed it, cleared the browser cache, rebooted the PCs etc.. No 
change it doesn't function anymore. This happened on 2 PC running 
Chrome-browser. I disabled browser synchronization. Still the same.

Here's an example URL from my WEB-site:
http://www.halo-photographs.com/2013-Bodypainting-Austria/content/NKB-700396.htm
l
>>>>insert!!!! (sorry, the  url above is a xHTML+RDFa1.0 page. The url to the 
page in question is indicated on top)
The Green Turtle shows, clicking it results in this:

Tried with the options enabling/disabling Microdata and Injection, still the 
same.
Any idea how to resolve this behaviour, what the cause might be?

Correction:

Greenturtle2.png is a false screenshot. Please disregard it.
Instead use Greenturtle3.png

Sorry about this mishap.

Alex, did you find time to look at it? Any idea?
On both machines in my browsers it is still happening. Once in while, as 
exceptional behaviour, I get the triples & graphs results. You're right, it 
seems like a timing issue.
Does it happen in your browser as well with this file?

Please keep me posted.
Thanks.
