Identifiers and Data Management

What is an identifier?
What is an identifier?
What you see: alphanumeric string (never changes)Associated with: location of object (such as a URL)
Optional: who, what, when, etc (i.e. metadata)

Identifier example
string: doi:10.9999/FK40K2GTVhtml version: http://dx.doi.org/10.9999/FK40K2GTV
location: http://www.bologna.edu/biology/xfg/123.xls
metadatacreator: Dr. Felix Kottortitle: Data for chromosomal study of catfish (Ictalurus punctatus)publisher: University of Bolognadate: 8/31/2012
Identifier example
string: doi:10.9999/FK40K2GTVhtml version: http://dx.doi.org/10.9999/FK40K2GTV

metadatacreator: Dr. Felix Kottortitle: Data for chromosomal study of catfish (Ictalurus punctatus)
publisher: Dryad Data Repository date: 10/01/2013
Why Identifiers are Important
Allow readers to find data products
Get credit for data and publications
Promote reproducibilityBetter measure of research
impact
Example:Sidlauskas, B. 2007. Data from: Testing for unequal rates of morphological diversification in the absence of a detailed phylogeny: a case study from characiform fishes. Dryad Digital Repository. doi:10.5061/dryad.20
Why Identifiers are Important
A&I Indexing and #altmetrics
• DataCite DOIs for data, linking to scholarly research
• Credit to data producers and data publishers
• Exposure and research metrics for datasets(Web of Knowledge, Google)
Primary Functions1. Create identifiers
2. Manage identifiers (and metadata) over time
3. Resolve identifiers

EZID and DataCite together
EZID: DOIs & ARKs
DOIs ARKs
Strict metadata requirements Flexible metadata guidelines
From the scholarly communication community
From the archives and museums community
Established “brand name” Option-rich, open source
Use case: Data Citation Use case: Data Documentation
DOIs and ARKs indata management plans
DOIs in data management plans
What it looks like: Sample plan language:
Aguilée R, Lambert A, Claessen D (2011) Data from: Ecological speciation in dynamic landscapes. Journal of Evolutionary Biology doi:10.5061/dryad.74024
Publication of data shall occur during the project, if appropriate, or at the end of the project, consistent with normal scientific practices.[Team] follows a standardized data product citation including DOI, that indicates the version and how to obtain a copy of that product.Why it’s important:
OSTP mandate to: identify and provide “appropriate attribution to scientific data sets”
Researcher benefits: Credit, increased citations, increased productivity
Data Citation
ARKs in data management plans
What it looks like:At top-level directory/folder:
Project TitleUnique IdentifierDate (yyyy or yyyy.mm.dd)
At sub-directories:optional identifiers at granular levels
Sample plan language:[Team] follows the recommended best practice for good data management by assigning unique identifiers (ARKs) to the data as part of the data documentation.
Why it’s important:
Researcher benefits: Data documentation helps you keep track of (and remember) aspects of your data throughout the research project.

Identifiers for data management
Identifiers + data=• Easy to access, • Easy to re-use • Easy to verify
