RDF stands for \"Resource Description Framework\" which is not a particularly informative acronym. Put simply, RDF is the way information is expressed semantically on the web.
Creative Commons Rights Expression Language (ccREL) is a specification describing how license information may be described using RDF and how license information may be attached to works.
CC+ is a protocol providing a simple way for users to get rights beyond the rights granted by a CC license. For example, a work's Creative Commons license might offer noncommercial rights. CC+ is CC license + Another agreement. It is NOT a new license, but a facilitation of morePermissions beyond ANY standard CC licenses.
With CC+, the license can also provide a link by which a user might secure rights beyond noncommercial rights. The basic concept is to have a Creative Commons license + some other agreement which provides morePermissions.
With CC+, the license can also provide a link by which a user might secure rights beyond noncommercial rights -- most obviously commercial rights, but also additional permissions or services such as warranty, permission to use without attribution, or even access to performance or physical media.
