Major Questions informing Research Where is at-risk data? How are scientists using historic data? How do we define at-risk? “ 8 inch floppy” Retrieved from: http://johnkingworld.com/aplus/images/storage-8inch-floppy.jpg How do others define at-risk? What must be done to rescue data-at-risk?

Major Question informing Scheme Design What is essential metadata for describing data-at-risk and aiding in data rescue?

Metadata requirements • Be applicable across a range of disciplines and scientific research areas. • Sufficiently support the data rescue mission.

Functions of the Inventory Function Initial Metadata Properties Describe data of scientific value that is at-risk of being lost, unused, or destroyed. 1. Science area 2. Nature of data 3. Date or date-span 4. Location of original 5. Present location Act as a starting point for the data rescue mission. 6. Expected future 7. Risk level

Data-at-Risk Inventory (DARI) Metadata Scheme: guiding principles • Simple • Broadly applicable • Extensible

DARI Metadata Scheme (current) DARTG DARI Metadata, Version 1.0 Metadata Element Name Element Description Research Area(s) The domains represented by DARTG experts and the more general category of “Other”. Title The name associated with the collection. Physical form of the data Paper, photograph, specimen, record book, magnetic tape, etc. Content and context of the data History, topic, etc. -- if known Name of current holder Institution, organization or individual. Dates associated with data Time period when data were collected. Size Extent, volume, size. Data condition Stable, deteriorating, etc. Risk level Poor storage conditions, limited storage time, etc. Known access and restrictions Public domain, private collection, etc. Notes Any additional information. Contact information Address or other contact information for the institution, organization or individual.

Case Study: introduction

Case Study: implementation

Case Study: Results
7 Dataset Descriptions total. 5 out of 7 were completed unassisted using the metadata template
13.5 out of 16 metadata elements considered useful on average (85%)
4 out of 5 scientists said they would use the inventory again

Case Study: conclusions
The purpose of the inventory had to be more clearly stated on the website
Instructions for filling out the web form had to be simple, but clear
3 metadata properties were determined unnecessary, 4 properties were altered for clarity
The remaining metadata properties were successful in their ability to cut across scientific disciplines while fully describing data-at-risk

Next Steps
Complete focus groups and surveys at UNC- Chapel Hill and elsewhere to determine possible use cases
Disseminate information and generate interest for the inventory and the Data-at-Risk project
Finalize the inventory design and start populating it
