6. What’s Wrong with this Picture?
“To test Benet’s (1998) theory of “politically-induced
intelligence” (Benet 1999, pg 8), use a hierarchical
corrected contingency model (see Altman & Smith 2010;
Edgeworth 1863). We apply this model to a snowball
sample (Glass 1973) of eligible voters14, to which the
standard Stanford-Binet (Stanford & Binet 1766) has
been applied. Our results show that adoption of
Pastafarrianism can be expected to yield an increase
mean intelligence by 10.3 points. ”

7. “How much slower would scientific progress be if
the near universal standards for scholarly citation of
articles and books had never been
developed?Suppose shortly after publication only
some printed works could be reliably found by
other scholars; or if researchers were only
permitted to read an article if they first committed
not to criticize it, or were required to coauthor with
the original author any work that built on the
original … *If+ printed works existed in different
libraries under different titles; if researchers
routinely redistributed modified versions of other
authors' works without changing the title or author
listed; or if publishing new editions of books meant
that earlier editions were destroyed?...” – Altman &
King 2007
Emerging Data Citation Practices
8. “Citations to unpublished data and personal
communications cannot be used to support
claims in a published paper”
“All data necessary to understand, assess, and
extend the conclusions of the manuscript must
be available to any reader of Science.”

Helping Journals Manage Data
9. Reality
Helping Journals Manage Data
Compliance is low even in
best examples of journals
Checking compliance
manually is tedious, hard
to scale
10. Attribution
• Cite data as first class work
• Identify contributors to data
Discovery
• Associate a persistent id with a
work
• Locate data via identifier
• Locate data integral to article
• Locate works related to data –
articles, derivatives, sources
Persistence
• Reference exists as long as referring object
• Evidence persists as long as assertions
based on evidence?
• Durability of data transparent?
Access
• Citation provides for mediated
access
• Access to surrogate
• On-line access to object
• Machine understandability
• Long-term human
understandability
Provenance
• Associate work with version of
evidence used
• Verify fixity of information
Principles for Data Citation
Theory: Use Cases Operational Constraints?
-Syntax
-Interoperability
-Technical contexts of use
11. Reference
• Formal syntax used within the text of a publication to denote a relationship
to an external object. May contain additional information about the
portion/subset of external object implicated. Also known as “in-text
reference”, “pin-cite”.
We applied contingency analysis to the greatest data ever. [Altman 2005]”
Citation
•Formal description of external object, used for location and attribution.

Analysis Approach
14. Principles for Data Citation
1. Status of Data: Data citations should be accorded the same importance in
the scholarly record as the citation of other objects.
2. Attribution: Citations should facilitate giving scholarly credit and legal
attribution to all parties responsible for those data.
3. Persistence: Citations should be as durable as the cited objects.
4. Access: Citations should facilitate access to data by humans and by machines.
5. Discovery: Citations should support the discovery of data and their
documentation.
6. Provenance: Citations should facilitate the establishment of provenance of
data.
7. Granularity: Citations should support the finest grained description
necessary to identify the data.
8. Verifiability: Citations should contain information sufficient to identify the
data unambiguously.
9. Metadata Standards: Citations should employ widely accepted metadata
standards.
10. Flexibility: Citation methods should be sufficiently flexible to accommodate
the variant practices among communities.
Data Citation Principles
15. Principles for Data Citation
• Author.
– The creator of the data set.
• Title.
– As well as the name of the cited resource itself, this may also include the name of a facility and the titles of the top collection and main
parent subcollection (if any) of which the data set is a part.
• Publisher.
– The organization (or repository) either hosting the data or performing quality assurance.
• Publication date.
– Whichever is later: the date the data set was made available, the date all quality assurance procedures were completed, or the date
the embargo period (if applicable) expired. In other standards an “Access Date” field is used to document the date the data set was
successfully accessed.
• Resource type.
– Examples: “database” or “data set.”
• Edition.
– The level or stage of processing of the data, indicating how raw or refined the data set is.
• Version.
– A number increased when the data changes, as the result of adding more data points or rerunning a derivation process, for example.
• Feature name and URI.
– The name of an ISO 19101:2002 “feature” (e.g., GridSeries, ProfileSeries) and the URI identifying its standard definition, used to pick
out a subset of the data.
• Verifier
– to verify the identity of the content.
• Identifier.
– A resolvable web identifier for the data, according to a persistent scheme. There are several types of persistent identifiers, but the
scheme that is gaining the most traction is the Digital Object Identifier (DOI).
• Location.
– A persistent URL or UNF from which the data set is available. Some identifier schemes provide these via an identifier resolver service.
Citation Metadata Elements
16. Gaps
• Metadata/Structural
– Granularity
– Version Control
– Microattribution
– Contributor ID
– Facilitation of reuse
• Practice
– Author: use of citations to data
– Journals: ad-hoc syntax and location
– Infrastructure: failure to index citations and references to
data, even when associated with DOI’s
– Tools: support for datasets in reference managers, etc.

1. The citation itself must be able to identify
uniquely the object cited, though
different citations might use
different methods or schemes to do
so.
2. It must be able to identify subsets of
the data as well as the whole
dataset.
3.
a. It must provide the reader with
enough information to access the
dataset;
b. indeed, when expressed digitally
it should provide a mechanism for
accessing the dataset through the
Web infrastructure.
4.
a. It must be usable not only by
humans but also by software tools,
so that additional services may be
built using these citations.
b. In particular, there need to be
services that use the citations in
metrics to support the academic
reward system, and services that can
generate complete citations.- See

Force 11
• Data should be considered citable
products of research.
• Such data should be held in persistent
public repositories.
• If a publication is based on data not
included with the article, those data
should be cited in the publication.
• A data citation in a publication should
resemble a bibliographic citation and be
located in the publication’s reference list.
• Such a data citation should include a
unique persistent identifier (a DataCite
DOI recommended, or other persistent
identifiers already in use within the
community).
• The identifier should resolve to a page
that either provides direct access to the
data or information concerning its
accessibility. Ideally, that landing page
should be machine-actionable to
promote interoperability of the data.
• If the data are available in different
versions, the identifier should provide a
method to access the previous or related
versions.
• Data citation should facilitate attribution
of credit to all contributors

• Bibliometric and network analysis are
the “telescopes” for exploring the
structure of science
• Researcher ID’s allow us to see more
connections, more reliably
• Identifiers for datasets, etc. reveal the
“dark matter” of science
Some potential questions:
• Are fields linked through evidence that are
not linked through publications?
• How is the practice of science changing – are
data scientists, statisticians, etc. making
bigger contributions?
• How would be the results of:
– Catalyzing new research collaborations among individuals,
organizations?
– Strengthening support for specific areas of
interdisciplinary research?
– Growing the evidence base in particular areas?
Questions about how network of contributors and outputs
evolves over time

The structure and design of digital storage systems is a cornerstone of digital preservation. To better understand ongoing storage practices of organizations committed to digital preservation, the National Digital Stewardship Alliance conducted a survey of member organizations. This talk discusses findings from this survey, common gaps, and trends in this area.(I also have a little fun highlighting the hidden assumptions underlying Amazon Glacier's reliability claims. For more on that see this earlier post: http://drmaltman.wordpress.com/2012/11/15/amazons-creeping-glacier-and-digital-preservation )
Data citation supports attribution, provenance, discovery, provenance, and persistence. It is not (and should not be) sufficient for all of these things, but its an important component. In the last 2 years, there have been several major efforts to standardize data citation practices, build citation infrastructure, and analyze data citation practices. This session presented as part of the the Program on Information Science seminar series, examines data citation from an information lifecycle approach: what are the use cases, requirements and research opportunities. And the session will also discuss emerging infrastructure and standardization efforts around data citation.A number of principles have emerged for citation -- the most central is that data citations should be treated consistently with citations to other objects:Data citations should at least provide the minimal core elements expected in other modern citations; should be included in the references section along with citations to other elements; and indexed in the same way.Adoption of data citation by journals can provide positive and sustainable incentives for more reproducible science and more complete attribution. This would act to brighten the dark matter of science -- revealing connections among evidence bases that are not now visible through citations of articles.
