Re: [Conformance] Thoughts/ edits on the Use Cases Document

Hi Gregg, this is good and examines a useful array of use cases and exceptions/qualifiers. 

A potential “raw data” exception:

Something I mentioned in a related thread some months ago, relates to “original data” for example:

Camera original .mov, .avi or similar movie files are often important to be kept as-is and unaltered, for evidentiary purposes for example. Embedding things like caption data (into the file) typically results in the file being re-compressed, which results in data loss. As such, a reasonable exception to the captioning requirement relates to camera original files which reasonably need to be left in their unaltered form.

Caption files can be created as sidecars, of course—and naturally, a separate version of the video file can be created to make captions available, but consider a site such as WikiLeaks, where information that is socially/politically important is held for dissemination. It is better that a site be able to hold a mass of such data than to be prohibited from doing so due to a compliance issue. And when possible, evidentiary data is best held/provided in an unaltered form.

Naturally, a commercial news operation should not be able to use such an exception when it comes to their prepared newscasts, but even a commercial news operation should be able to provide raw/unaltered footage as a separately available file, and “raw” files can not reasonably be required to be altered.

As such, this points to needed exception language for raw, original, and archival materials.
