Hi Tong,

Ah ok. Visual and layout information is quite important for my 
extraction tasks. My rule language has the capability to dynamically 
filter all kinds and combinations of markup and annotations types. 
Therefore the original HTML text stays the main artifact in the xmiCAS 
even if the tags contain no valuable information. I plan to integrate 
"external" annotators with restrictions also in that manner.

I am not sure if I understand you. The structure or text of the HTML 
cannot be modified by the CEV plugin (the rule language does such 
things). I think the only real advantage to the CAS Viewer and the CAS 
Editor is that the CEV can display annotations of an HTML artifact in 
some kind of browser and the user can create new annotations in this 
browser. It is really painfully to review or edit annotations in the 
HTML source. There is probably no reason (except maybe the extension 
point) to use the CEV plugin instead of the CAS Viewer if you are just 
processing plain text.

Yes, I will provide a simple example next week.

Have a nice weekend!
