The document discusses the potential for open sharing and reuse of educational resources online through open licensing. It makes several key points:
1) It is becoming easier to access and reuse online works, but legal barriers around copyright remain.
2) Most teachers do not own copyright to the resources they create, and schools lack clear policies on sharing.
3) Open licensing schemes like Creative Commons can help address this by allowing legal reuse and dissemination of resources while respecting author rights.
