There was a request recently for the Tagalus database to be downloadable. In the interest of data transparency, we’ve added that feature.
In the footer of each page on Tagalus, there is a link called “Download DB,” which points to a tarball that includes all tags, definitions, and comments on Tagalus. Note: the link may change locations on the page/site at some point, but the URL (http://tagal.us/backup_db) will stay intact. User id numbers are referenced, so analysis can be done, but for privacy reasons, no other user data is included.
The database file is not completely real-time – it is created by a backup process that runs twice a day, so downloading the DB each time you add a new tag isn’t effective right now, since it won’t be reflected in the tarball until the next backup process runs.
Also, to combat abuse, you must be logged in (using an OpenID or Twitter user name) in order to download the database. Users will be blocked if they attempt to abuse the service.
Enjoy!
