PLoS ONE launches with document meta layers and linking

I think if anyone can figure out how to do annotation well, that will be a killer app, but so far there is no "YouTube for annotations".

Most of the PLoS content is not very accessible/interesting to me, but I did explore Concentration of the Most-Cited Papers in the Scientific Literature: Analysis of Journal Ecosystems. PLoS supports both annotations and discussions.

As well, many (but not all) of the reference have a "find this article online" link. As far as I can tell, it parses the link up into a format it can pass to PubMed or Google Scholar. So for example

Garfield E. (2006) The history and meaning of the impact factor. JAMA 295: 90–93.

has a link

http://www.plosone.org/article/findArticle.action?author=Garfield&title=The history and meaning of the impact factor.

presumably if you want to hack, err, "mashup" PLoS findArticle, you just have to pass it an appropriate author= and title=

When you click the above link, you get yet another PLoS page, which says

The article may exist at:

* PubMed/NCBI
* Google Scholar

which seems like a rather click-heavy way to get to a result set.

The links it constructs are

http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=PubMed&cmd=Search&doptcmdl=Citation&defaultField=Title+Word&term=Garfield%5Bauthor%5D+AND+The history and meaning of the impact factor.

http://scholar.google.com/scholar?hl=en&safe=off&q=author%3AGarfield+%22The history and meaning of the impact factor.%22

Is it just me or are we maybe not leveraging the full richness of article metadata here?
As far as I can tell, PLoS ONE knows nothing about OpenURLs, or resolvers.
