Future migration of JPEG 2000 blog post

We announced the creation of our JPEG 2000 blog last month, and since then we have posted on several aspects of our experiences implementing the format, including setting up a Working Group around JPEG 2000 use in the library, museum and archive world. The blog has been well received so far, with several thought-provoking comments and over 800 visitors in its first month.

In a recent post, Digital Curator Dave Thompson discusses issues around the long-term management of JPEG 2000. Our current approach demonstrates that, while we have chosen a lossy format for our master image files, we are not ignoring the future implications of our actions:

"Obsolescence is not something totally beyond our control. We are free to decide when obsolescence actually occurs, when it becomes a problem we need to deal with, and, with proper long term management strategies how we plan to migrate from obsolete formats to current ones. The choice of JPEG2000 as a master format supports this broader approach to data management." Read more...

As a library, long-term preservation of information is a key service that we provide: not only for our physical collections, but for our digital holdings as well.
