STEM EXCHANGE WORKFLOW OVERVIEW The STEM Exchange is being built by the National STEM Digital Library as a web service to capture and share social media-generated information and other networked associations about educational resources. Through an open API, online communities of educational practitioners will be able to integrate customizable datastreams about resources from NSDL and other providers directly into their user platforms. The social media activities of practitioner communities will generate data about how resources are being used in different contexts that the STEM Exchange will assembly into resource profiles incorporating both handcrafted and automatically captured information. The resulting paradata describing resource use will be feed back into resource profiles to assist users in discovering and utilizing educaional materials and to enhance resource providers’ understanding of how their materials are being disseminated, used, and contextualized by practitioners. © 2010 NSDL/UCAR
