Module 7: Archiving and Preservation

Exercise Review UT’s Research Data Policy again with respect to preservation of research data. Does it have limitations? What are some ramifications of following this policy?

Exercise Search Databib.org for a repository relevant to your discipline and attempt to download a dataset from the repository. (FYI, you may run into a lot of repositories that are down because of the government shutdown.)

Exercise What descriptive information would you need to provide with a data set for someone 20 years in the future to understand it and be able to use it? Think back to the metadata module this morning.
