David Shotton proposes The Five Stars of Online Journal Articles…

“I propose five factors — peer review, open access, enriched content, available datasets and machine-readable metadata — as the Five Stars of Online Journal Articles.”

From a search perspective, I might suggest we need to add another star for “Googlyness”, when all the following factors are present…

* search-engine friendliness (i.e.: make sure the article title shows up as the clickable link in search results, not something like “43w94.taryyt.indd”)

* RSS feeds for linked tables-of-contents

* embedding of the journal title and home URL in each individual PDF or HTML article page (so they can be easily tracked back, after they get casually downloaded to a hard-drive)
