Marjan will give an overview of the role of data archives in ensuring the safe stewardship and preservation of data over time. She will explain what it means to be a Trustworthy Digital Repository and the associated policies and processes that need to be in place to ensure data provenance and authenticity. This session will link to Monday’s exploration of the re3data.org portal Visit: https://www.eudat.eu/eudat-summer-school

1. What is the oldest
data that you have
used or looked at,
i.e. not generated by
you?
2. Where did you find it?

For
aspiring repositories
reviewers
Also about
data producers
data users
Requirements 1–16

14. EUDAT Summer School, 3-7 July 2017, Crete
Levels of curation
Plus R0: context and “Level of Curation Performed”
”All levels of curation assume initial deposits are retained unchanged (…) edits are only
made on copies of those originals.”
“Annotations/edits must fall within the terms of the licence agreed with the data
producer...”
“the repository will be expected to demonstrate that any such annotations/edits are
undertaken and documented by appropriate experts”

15. EUDAT Summer School, 3-7 July 2017, Crete
Exercise
Download the Draft CoreTrustSeal Guidance
document, read the guidance about Requirements
10, 7 and 14, and answer the following questions:
Ad R10: what does this mean for you as a data
producer?
Ad R7: next time you look for a repository to deposit
or reuse data, will it differ from last Tuesday? How?
Ad R14: what does this mean for you as a data
reuser?
