Ascribenation is the act of ascribing credit to a source or set of sources, for a piece of media work. That work might be a newspaper story, a blog post, or a song mashed from multible sources or samples. It is derived from the verb ascribe.
Ascribenation is not possible without sources carrying ascribenation metadata that can be concatenated forward as each source's work is included in other works. There are several means for doing this, including microformats and XDIs.
Ascribenation makes possible crediting sources for work, and getting those sources paid as well.
For example, here's a Houston Chronicle story on climate change lobbying] that sources an analysis of climate change lobbying by the Center for Public Integrity. Right now the Chronicle doesn't have any links in that story. But if it did, that link might contain concatenated metadata that could be gathered by the Read Log on the reader's device (phone, laptop, whatever). Using PayChoice, the reader could pay both the Chronicle and the Center for Public Integrity.
