PerX Project and 'Marketing' with Metadata

PerX (Pilot Engineering Repository Xsearch) is a two-year JISC Digital Repositories Programme project, which is developed to provide a cross-repository search tool for the engineering learning and research community. PerX has released an advocacy document entitled "Marketing with Metatdata - How Metadata Can Increase Exposure and Visibility of Online Content" which introduces the means by which content providers can share, or embed, their descriptive data (metadata), with other websites, in standard and reusable ways. This document seems very useful for those, interested in what ways medatada can be exposed.
