A question about open databases license

Yesterday I made my first contribution to the OpenStreetMap project by 
adding a node that describes the shop at Berliner Stra├če 8 in Frankfurt 
am Main, Germany. OpenStreetMap uses the ODBL[1]. Recently I found out 
that a free software clone of VOCALOID uses the same licence. However 
you could also use the GPL for databases such as soundfonts. Freepats 
adds an exception to the GPL[2], wich allows use of the soundfont in 
proprietery compositions.
I don't know if one of the licences fits your needs.
