Hello everyone.

Thanks Adrian, yes that helps. I was thinking of the case where the page 
was the primary thing described.

Here's the example of a page describing a resource elsewhere that I have 
marked up with schema.org so that both the page and the resource that 
the page is about are described: 
http://pjjk.net/lrmiexx/nsdl20110414163807295T.htm  Rich Snippets 
testing tool output is available at http://bit.ly/HXSdgr (I've also used 
some of the LRMI proposed properties, which are the ones that the 
testing tool does not recognise)

I can easily see how specifying that the page and the learning resource 
that the page is about have different properties (different authors, 
different terms of use etc). However it is the learning resource that is 
the most important item it is the description of the learning that we 
want search engines to notice yet that is kind of hidden away as Item 2 
in the parsed output. I guess I doubt whether a search engine would 
bother to do much with any information provided by schema.org for the 
thing that a page was about?

The alternative is not to mark up only the information on the page for 
the resource being described. There's an example of that at 
http://pjjk.net/lrmiexx/nsdl20110414163807295T_2.htm with testing tool 
output at http://bit.ly/HNGk85  I guess the search engines are more 
likely to act on the important information in this case because it's all 
properties of the primary item, but how will they trust to a page on one 
website to describe a page elsewhere?

I would be interested in knowing how the markup on either example page 
aligns with current or expected practice.

Regards, Phil
