Linked data refers to RDF and related technologies for enabling data to be published in a decentralized fashion on the Web. With linked data, each piece of information can be expressed in terms of, and with relations to, arbitrary other information produced by others.
By letting information be richly contextualized, Linked Data forms the core technology underlying Semantic Web applications and services.
mashpoint is a framework that allows data rich apps to be connected and browsed in a new way. It allows selections of data from one app to be inputed in other apps, improving discovery of information on a more granular level.
