[Data-modeling] Roud Folk Song Index

[Iain Sproat]

I stumbled across the Roud Folk Song Index on wikipedia -
http://en.wikipedia.org/wiki/Roud_Folk_Song_Index

A database of folk songs and traditional ballads would be great on
Freebase, and I've started a Folk song base
http://www.freebase.com/view/base/folkmusic/folk_song?domain=/base/folkmusic
 Please feel free to contribute.

Does anyone know anything about the database behind the Roud Index? -
I've googled it but I'm unable to find out if the database is open
source or if it's even available as a downloadable file.  I did find a
searchable online access to it
