SCOOTEROER6_OER_Production_Flow_Diagram_20Jan11 (direct link to HTML interactive version)
These are a series of OERs on how to produce good quality learning resources for release as open content, and they include a flow diagram of everything that you need to consider from start to finish. The flow diagram helps you consider copyright and technical aspects of working with new and existing content, and how to work with material that may belong to external parties and third parties.
The resources include a number of Jisc permissions forms that you will need to complete to gain copyright and recording permission and also very useful resource creation checklists from the RLO CETL (Nottingham, Cambridge and London Metropolitan University). (The above HYPERLINKS will take you through to where you can download these forms and specifications for your own use).
