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)

Why Identifiers are Important

Allow readers to find data products

Get credit for data and publications

Promote reproducibilityBetter measure of research

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: 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.
