Last weekend i attended WordCamp Stockholm, where David Hall, aka @moonhouse, took the opportunity to build my idea, creating a widget that creates “Info boxes” based on links to Wikipedia in your blogpost, via DBpedia. The Widget displays information on something that you are writing about, for example 3-d printers. What info is displayed is determined by links to Wikipedia in the blogpost. Have look at the info on the 3-d printer below.
Some restrictions exists, such as, it doesnt handle croslinking between different articles in Wikipedia, and it only manages english links so far. (David says its because its the english title that defines the key).
You can fork the code from Davis at Github. (Grab the latest version)
*H3info is a WordPress plugin that automatically fetches excerpts of Wikipedia articles from DBpedia when such articles are linked from within a blogpost.
