Thanks for your comments. Here's how I've addressed them.

I've removed the word "meaning," and changed to "structure," in order to 
avoid the rabbit hole. I've kept the sentence since I think it gives a 
purpose to the effort, a purpose which was lacking in previous drafts 
and about which some reviewed complained.

> s/indications/indicators/


> - Section 2.3, paragraph 1
> s/Eve guest blogs, too/Eve guest blogs too/

I think the comma is grammatically correct, but I'll check.

> - Section 3
> "In addition to data about her blog entry, Alice wants to make her contact

> "In addition, Alice wants to make information about herself (email address,

Hmmm, I disagree :) RDF can describe anything, since URIs can be 
anything, including blank nodes, non-dereference-able URNs, etc...

Left this as is.

I like your simplification, but the rest of the wordage there exists for 
a specific purpose: to describe the concept of a "field name" which I 
use in the rest of the document once or twice.

I think we have to live with the slightly more complicated version.

OmniGraffle. http://www.omnigroup.com/applications/omnigraffle/
which, as of v5, supports SVG export, so I'll have to check that out. 
PNG for now :)
