Week 5 Muddiest Point

I'm a little confused about the definition of "Lossless" compression. Why is a GIF considered a lossless image format if not all of the colors are reproduced?

Week 5 Notes

Data Compression

Imaging Pittsburgh
This was really interesting. Particularly interesting was the discussion of selecting a Metadata Schema, and a common vocabulary for cataloging the images. I noticed that they elected to use a combination of Dublin Core metadata scheme and Library of Congress Subject headings for the cataloging of the images. I realize that DRL had their reasons for going going with LCSH, but I wonder whether Dublin Core has a set vocabulary. MODS will have the benefit of having a built in vocabulary, I assume.

I have to wonder why we are using Panopto. I realize that YouTube videos are limited to ten minutes in length, but using some form of Flash video hosting would solve a lot of the compatibility issues, right?
