Not a complete answer, I know. However it’s worth bearing in mind the huge performance improvements we’ve seen in all Javascript engines in the last year. And there’s probably more to come.

A few more notes on the WYSIWYG editing and RDFa processing can be found here on a blog post I’ve just knocked up.

Yeah, there is javascript to read it. The issue for browser extensions is that they need to parse every page you go to, and even smallest performance penalty means unsatisfied users. That’s why I hope you are working with Mozilla and others to add native get_rdfa_subtree() or something similar.

I hope it is fixed in the same way as native implementation of getElementsByClassName() in browsers fixed many performance issues regarding dynamic web pages.

Andraz, I am just a go-between here, having edited the case study for publication. I do not have a link to an online demo, I guess you should ask the Talis guys for this…

As for the second item: I understand:-( Having said that, afaik the Yahoo! searchmonkey toolkit does find RDFa content, ie, it is not impossible. Also, again unless I am mistaken, Ben Adida has some javascript routines to find RDFa content…

Cheers

Ivan

That’s a nice one. Do you know of any such online demo?

I am having hard time believing it works and would like to try out if I am imagining it correctly. Browsers have so much tendency to create spaghetti markup every time you use their WYSIWYG capabilities.

btw: In semantic tagging group we have just found another big barrier for RDFa adoption: browsers don’t support finding it in efficient way. Producers of browser extensions that provide additional services on top of web pages said it’s a non starter until there’s a fast function to actually find out if RDFa is present and where it is.
