This document proposes a project to promote linked open data in agriculture and nutrition. It would support 20-30 data providers to adopt interoperability standards and share information through common technologies and directories. The project has three workstreams: 1) establishing reference infrastructure of standards and directories; 2) developing an open technology architecture; and 3) building capacity through mentoring and competitive grants. A lead organization would manage the effort and subcontract core partners to implement workstreams. Monitoring and evaluation would assess the impact of making data more open and linked. The total estimated cost is $8.5 million over 3-4 years.
