License Compatibility Checker

Put the licenses of the works you want to combine into one bundle. The DALICC reasoner checks them against each other. When they fit together, pick the license you would like to publish the result under, and the checker composes a licensing statement you can download and keep with your work.

DALICC checks licenses against their models and does not replace legal advice. For a decision that matters, ask a lawyer.

The reasoner decides what conflicts with what from this graph. The default is the curated DALICC graph; see what it says, or read how the check uses this graph. While you are signed in, your own graphs and the ones shared with you are offered here too, drafts included, so you can try a graph out before you publish it. Whichever graph you pick is written into the statement you download.
