I'm OK with this but I'm confused why we are doing this rewrite at all. 
The original version on Tim's DesignIssues page [1] seems perfectly 
usable to me:

"""
1. Available on the web (whatever format) but with an open licence, to 
be Open Data
2. Available as machine-readable structured data (e.g. excel instead of 
image scan of a table)
3. as (2) plus non-proprietary format (e.g. CSV instead of excel)
4. All the above plus, Use open standards from W3C (RDF and SPARQL) to 
identify things, so that people can point at your stuff
5. All the above, plus: Link your data to other people’s data to provide 
context
"""

I'm not sure what value is been added by saying the same thing in 
slightly different words.

[OK I know there was some pushback on the mention of excel in #3, I 
would be OK with deleting "instead of excel" in the interests of side 
stepping that. But as I say, I guess I'm OK with the versions in this 
thread too.]
