Don't treat ordinal data as metric -- update of movie ratings
"In a previous post I applied a Bayesian ordered-probit model to movie ratings and showed how the results differ from treating the data as if they were metric. The metric model used frequentist t tests (because that's what most applied researchers would do). In this post, I re-analyze that data as if they metric but using a Bayesian model that has the same hierarchical structure as the Bayesian hierarchical ordered-probit model I used before. Here we can compare ordered-probit to metric treatments with all else held constant. Spoiler: Same conclusions, of course. The ordered-probit model fits the data much better than the metric model. Don't treat ordinal data as metric."

The BagIt File Packaging Format (V1.0)
BagIt is a set of hierarchical file layout conventions designed to support storage and transfer of arbitrary digital content. A "bag" consists of a directory containing the payload files and other accompanying metadata files known as "tag" files. The "tags" are metadata files intended to facilitate and document the storage and transfer of the bag. Processing a bag does not require any understanding of the payload file contents, and the payload files can be accessed without processing the BagIt metadata.
