Developers Ryan Chute and Herbert Van de Sompel introduce djatoka (silent "d"), an open source jpeg 2000 image server, in a recent d-lib Magazine article. They comment that "the flexibility offered by both OpenURL and OCLC's OpenURL package provides a solid basis for adding image dissemination services on the basis of the same architectural framework."
Jeff has been considering the OpenURL Framework from the perspective that six simple questions convey the essence of the OpenURL model: what, why, who, where, when, and how. Jeff writes about this perspective on his blog, Q6.
