Why are there different jurisdiction licenses?
One of the main goals of CC is to create a group of standardized licenses that have the same effect anywhere across the globe. However, creating a single license that will have the same legal effect in all jurisdictions can be difficult, particularly as each jurisdiction will usually have its own legal language, definitions and drafting rules. This is why the CC jurisdiction projects create jurisdiction-specific versions of each of their licenses. These licenses are designed to have the same effect anywhere in the world while at the same time following the legal conventions of particular jurisdictions, so that they can be more easily understood and used by the local community.
