I was testing the Structured Blogging plugins—particularly Dan Chudnov's Journal Article review template—with NotePress and needed a way to look up articles and automatically fill in the form fields as the book, CD and DVD review templates do using Amazon.
So, here's a PubMed Journal Article review template (and a couple of core plugin files that need to be replaced) that will let you search for articles by title and automatically fill in the metadata: →download←
review-pubmed-article.xml in /wpsb-files/microcontent/descriptions/
sb-get.php in /wp-admin/
sb-lookup.js in /wpsb-files/
Update: This is now included in the official Structured Blogging plugin.
