Edit content tagged schema.org with Chrome or Safari

[adou600]

As illustrated on https://gist.github.com/4326769, it is currently not possible to edit content with Safari or Chrome, if this content is for example of type http://schema.org.

There is a JS error in vie-min.js preventing to display the edit button:
Uncaught Error: No prefix found for CURIE 'sc:WebPage'!

VIE comes with a set of pre-registered namespaces: https://github.com/bergie/VIE/blob/master/src/VIE.js#L90

For any other ones, you either have to declare them via xmlns in your DOM, or programmatically using:

vie.namespaces.add("myprefix","http://example.net/ns#");

What I don't get is that the namespace is defined in the DOM via xmlns:

<div xmlns:dcterms="http://purl.org/dc/terms/"
        xmlns:sc="http://schema.org/" 
        xmlns:cw="http://schema.org/CreativeWork/" 
        xmlns:ar="http://schema.org/Article/" 
        typeof="sc:WebPage" 
        about="/cms/simple/get-started">
    ...
</div>

Isn't that weird that the exact same page works with Firefox and not with Safari and Chrome?

I tried to handle the problem with other solutions like to have a full NS in the typeof attribute, but I could'nt find a case that worked...
