I've just started creating a wikipedia infobox to annotate the biological databases in wikipedia. If many articles use this template, then it will be possible to parse the them and to create a list of the databases providing some web services, some SPARQL endpoints, having a download area etc...
The infobox itself is still a draft, so feel free to modify it or to suggest some other fields in the 'Talk' page.
Via the Freebase blog.
The Freebase Wikipedia Extraction (WEX) http://download.freebase.com/wex/ is a processed dump of the English language Wikipedia. The wiki markup for each article is transformed into machine-readable XML, and common relational features such as templates, infoboxes, categories, article sections, and redirects are extracted in tabular form.
Freebase WEX is provided as a set of database tables in TSV format for PostgreSQL, along with tables providing mappings between Wikipedia articles and Freebase topics, and corresponding Freebase Types
