Overview
abstract
JPEG 2000 is the product of thorough efforts toward an open standard by experts in the imaging field. With its key components for still images published officially by the ISO/IEC by 2002, it has been solidly stable for several years now, yet its adoption has been considered tenuous enough to cause imaging software developers to question the need for continued support. Digital archiving and preservation professionals must rely on solid standards, so in the fall of 2008 the authors undertook a survey among implementers (and potential implementers) to capture a snapshot of JPEG 2000's status, with an eye toward gauging its perception within this community. The survey results revealed several key areas that JPEG 2000's user community will need to have addressed in order to further enhance adoption of the standard, including perspectives from cultural institutions that have adopted it already, as well as insights from institutions that do not have it in their workflows to date. Current users were concerned about limited compatible software capabilities with an eye toward needed enhancements. They realized also that there is much room for improvement in the area of educating and informing the cultural heritage community about the advantages of JPEG 2000. A small set of users, in addition, perceived problems of cross-codec consistency and future file migration issues. Responses from non-users disclosed that there were lingering questions surrounding the format and its stability and permanence. This was stoked largely by a dearth of currently available software functionality, from the point of initial capture and manipulation on through to delivery to online users.
