Clarifying licenses in Mantis

As many of you might know, several ANS projects, like OCRE and CRRO, already have well-defined Open Database Licenses. In the ANS database itself, Mantis, we had a generic copyright and terms of use statement. We have moved forward with clarifying the licenses on Mantis. The data are made freely and openly available with an Open Database License. The images themselves are now under the Creative Commons Attribution/Non-Commerical license. People are free to link to our coin images from external sites and projects. While this may have been going on anyway, we have now formalized the right to do this.
