Why are we here?
But why are we really here?
 An Impetus: NSF recently released a mandate that all grant
applications submitted after January 18th, 2011 must include a
supplemental “Data Management Plan”
 An Effect: This mandate from NSF has had a domino effect,
and many funders that now require or state guidelines for
data management of grant funded research
 A Challenge: Data management (and oftentimes research
methods in general) is an area that has not traditionally
received a full treatment in most graduate and doctoral
curricula
What is meant by “data management”?
Fundamental Practices
 File Organization
 Data Documentation
 Reliable Backups

Effective January 18, 2011
NSF will not evaluate any proposal missing a DMP
May be up to two pages long
PI may state that project will not generate data or
samples
 DMP is reviewed as part of intellectual merit or
broader impacts of application, or both
 Costs to implement DMP may be included in
proposal’s budget
NSF’s Data Management Guidelines
 Policies for re-use, re-distribution, and creation of
derivatives
 Plans for archiving data, samples, and other research
outcomes, maintaining access
 Types of data, samples, physical collections, software
generated
 Standards for data and metadata format and content
 Access and sharing policies, with stipulations for
privacy, confidentiality, security, intellectual property,
or other rights or requirements
Other Federal Policies
“expects the timely release and sharing of final research
data"
“…should describe how the project team will manage
and disseminate data generated by the project”
“requires that data…be submitted to and archived by
designated national data centers.”
NASA “promotes the full and open sharing of all data”
"IMLS encourages sharing of research data."
Upfront Decisions for Researchers
 What is the expected lifespan of the data?
 Besides the researcher(s) on the project, who else
should be given access to the data?
 Does the dataset include any sensitive information?
 Who owns or controls the research data?
 Should any restrictions be placed on the dataset?
 How are the data stored and preserved?
Upfront Decisions for Researchers
 How might the data be used, reused, and
repurposed?
 How is the data described and organized?
 Who are the expected and potential audiences for
the datasets?
 What publications or discoveries have resulted from
the datasets?
 How should the data be made accessible?
Data Sharing Impacts
 Reinforces open scientific
inquiry
 Encourages diversity of
analysis and opinion
 Promotes new research,
testing of new or
alternative hypotheses
and methods of analysis
 Supports studies on data
collection methods and
measurement

Data Sharing Impacts (cont.)
 Facilitates education of
new researchers
 Enables exploration of
topics not envisioned
by initial investigators
 Permits creation of
new datasets by
combining data from
multiple sources

File Organization Practices: Overview
1. Create a file plan for your
research project
2. Design a file naming
convention that works for
your project
3. Agree on a version control
method to assist with file
synchronization
4. Carefully choose file
formats to maximize
usefulness
“When I was a
freshmen I named
my assignments
Paper Paperr
Paperrr Paperrrr”
-Undergrad
1. Create a file plan for your research project
 File plan as a classification system
 Indexed – makes it easier to locate folders/files
 Primary subjects – main functions of research project
 Secondary subjects – more specific activities of project,
including research data
• Tertiary subjects – limit by date or equivalent
– File Name (naming conventions)
1. Create a file plan for your research project
(cont.)
Example documentation of Directory Hierarchy:
 /[Project]/[Grant Number]/[Event]/[Date]
Example documentation of File Naming Convention:
 [investigator]_[method]_[descriptor]_[YYYYMMDD]_[version].[ext]
2. Design a file naming convention that works
for your project
 Why file naming conventions?
 Enable better access/retrieval of files
 Create logical sequences for file sorting
 More easily identify what you’re searching for
2. Design a file naming convention that works
for your project (cont.)
 Meaningful but short (255 character limit)
 Descriptive while still making sense
 Capital letters or underscores differentiate
between words
 Surname first followed by initials of first name
 More on handout
2. Design a file naming convention that works
for your project (cont.)

3. Agree on a version control method to assist
with file synchronization
 Version number of record indicated file name
with “v” followed by version number
 Letter “d” indicates draft
Examples of simple version control:
waltM_lakeLansing_fieldNotes_20091012_v002.doc
petersK_OrgChart2009_d001.svg
4. Carefully choose file formats to maximize
usefulness
•
•
•
•
•
•
Non-proprietary
Open, documented standard
Common usage by research community
Standard representation (ASCII, Unicode)
Unencrypted
Uncompressed
Documentation Practices: Overview
1. At minimum create a
README file that you can
use to document your
project
2. Utilize standards for
describing data including
Metadata Standards
3. If applicable, use in-line
code commentary to
explain code
(cc) Will Scullin
1. At minimum create a README file that you
can use to document your project
 At minimum, store documentation in readme.txt file or
equivalent, with data
 Resource: http://libraries.mit.edu/guides/subjects/datamanagement/metadata.html
2. Utilize standards for describing data including
Metadata Standards
 “Data about data”
 Standardized way of describing data
 Explains who, what, where, when of data
creation and methods of use
 Provides the essential tools for discovery, such as
a bibliographic citation
2. Utilize standards for describing data including
Metadata Standards
Basic project metadata:
• Title
• Language
• File Formats
• Creator
• Dates
• File Structure
• Identifier
• Location
• Variable List
• Subject
• Methodology
• Code Lists
• Funders
• Data Processing
• Versions
• Rights
• Sources
• Checksums
• Access
Information
• List of File Names
Documentation Practices: Example Metadata Standards
 Dublin Core
Easy-to-create-and-maintain descriptive format to
facilitate cross-domain resource discovery on the Web
 Darwin Core
Facilitates reference and sharing of biological diversity
datasets
 Data Documentation Initiative (DDI)
Methodology for content, presentation, transport, and
preservation of metadata about datasets in the social
and behavioral sciences
Documentation Practices: Example Metadata Standards
 Directory Interchange Format
Descriptive format for exchanging information about
earth science data
 ISO 19115:2003
Describes geographic data such as maps and charts
 PBCore
Supports description and exchange of media assets,
including both individual clips and full, edited, aired
productions
Documentation Practices: Example Metadata Standards
 Science Data Literacy Project
Metadata for astronomy, biology, ecology and
oceanography
 VRACore
Data standard for description of works of visual culture
as well as images that document them
3. If applicable, use in-line code commentary to
explain code
Example of R code commentary
# Cumulative normal density
pnorm(c(-1.96,0,1.96))
Backup Practices: Overview
1.
2.
3.
4.
Avoid single points of failure
Understand the different types of storage
Ensure data redundancy
Aim for geographic distribution of data
1. Avoid single points of failure
A single point of failure occurs when it would only take one
event to destroy all data on a device (e.g. dropped hard drive)
Good practices for avoiding single points of error:
 Use managed networked storage whenever possible
 Move data off of portable media
 Never rely on one copy of data
 Do not rely on CD or DVD copies to be readable
 Be wary of software lifespans (e.g. Angel)
2. Understand the different types of storage
•
•
•
•
•
•
Flash Drives
Internal Hard Drives
External Hard Drives
Server and Web Storage
Managed Networked Storage
Cloud Storage
3. Ensure data redundancy
Backup Do’s:
 Make 3 copies
 E.g. original + external/local + external/remote
 E.g. original + 2 formats on 2 drives in 2 locations
 Geographically distribute and secure
 Local vs. remote, depending on needed recovery time
 Personal computer, external hard drives,
departmental, or university servers may be used
3. Ensure data redundancy (cont.)
Backup Don’ts:
 Do not rely on one copy
 Do not use CDs and DVDs
 Do not rely on ANGEL

Research is…
?
The scientific method “is
often misrepresented as a
fixed sequence of steps,”
rather than being seen for
what it truly is, “a highly
variable and creative
process” (AAAS 2000:18).
