NSF DataNet Program• new types of organizations that integrate library & archival

sciences, cyberinfrastructure, computer & information sciences, & domain science expertise

• provide reliable digital preservation, access, integration, and analysis capabilities for science and/or engineering data over a decades-long timeline;

• continuously anticipate and adapt to changes in technologies and in user needs and expectations;

• engage in research to drive the leading edge forward• serve as component elements of an interoperable data

preservation and access network

Partners

• SEAD’s Unique Contributions– Address domain-driven

needs & requirements– Serve scientists and

researchers in the “long tail”– Integrate existing

technologies, tools & services (rather than build new from scratch)

Data challenges• Heterogeneity

of all kinds• Multiple scales• Multidisciplinar

y• Many small

datasets

The long tail of scientific research

• Small and derived data sets• Heterogeneous data• Multiple sources of data• Short-lived data with long-term

value• Value of data grows when

combined & integrated

SEAD’s Goals• Provide data services that address the needs of

researchers working toward sustainability• Integrate these services into an generalizable

“Active and Social Curation” infrastructure suited to the social structure and economics of long-tail research communities

• Develop capabilities to package and migrate the most valuable datasets to a federated repository infrastructure for long-term preservation

• Education, outreach, & training to disseminate SEAD’s contributions to other projects & communities

SEAD’s Strategy

• Leverage social media for discovery of data, interest, and expertise

• Move data curation upstream in the data life cycle

• Involve domain scientists in setting priorities for evolution of data and services

• Take advantage of existing infrastructures (Institutional Repositories, ICPSR) for long-term preservation

Active and Social Curation• Engage researchers during projects,

not at the end• Automatically capture metadata as

defined by the data producers• Provide facilities for commentary,

recommendations, and mark-up of data• Further reduce costs by re-engineering

curation processes to leverage this rich metadata and volunteered effort

SEAD Cyberinfrastructure• An international

resource for sustainability science

• Novel technical and business approaches to supporting the long-tail of research data

• Lifecycle support: actionable data services integrated with curation and preservation infrastructure

Key Challenges for SEAD Cyberinfrastructure

• Managed Data storage and services are expensive!• Begging for metadata doesn’t work!• Curation and preservation are time consuming!• The long-tail is not standardized!• Data collections are always missing something

valuable!• Data models evolve!• Cyberinfrastructure is obsolete by the time you

build it!• Building Community as you leverge

SEAD: Social Networking

•Co-authorship•Co-funding•Micro-citation•Shared project repositories•Shared tags•Threaded discussions•Quoting, forwarding, …

Linked Data and Repositories•Tag and annotate data•Overlay it with reference data•Organize it in domain terminology•Link it to people, papers, projects,

conversations…

Using Science of Science to Link Repositories

KEY SEAD Questions

•What could SEAD capture when?

•How can SEAD provide direct value to data producers, users, and curators?

•How can robust web-services and social computing lower barriers and reduce/realign costs?

SEAD: Active Content Repository•With the ‘Big Picture’ graph in-hand,

curators can:▫Focus on what to curate and when,▫Automate parts of the process▫Use existing/emerging technologies for

packaging and preserving datasets▫Better manage federated repositories

SEAD: Leveraging Existing Resources

•Cyberinfrastructure▫IU Data Capacitor/HPC Capabilities▫UIUC/NCSA HPC Capabilities▫Rensselaer CCNI Capabilities

•Repositories▫UM Deep Blue▫IU ScholarWorks▫ICPSR Repository▫UIUC IDEALS

SEAD CI QuickView• SEAD will quickly build a repository and data services

infrastructure for sustainability research that can be responsively adapted based on community feedback – Community Agile Development

• SEAD will leverage existing tools and emerging practices to dramatically enhance the interactions of researchers and data librarians – Active Curation

• SEAD’s focus on the long-tail will force an emphasis on ease-of-use and low costs that is critical for long-term sustainability – Leverage Existing Institution Resources for Long-term Access

• SEAD will leverage experiences in the sustainability research community to provide guidance for other long-tail communities making the transition to an interdisciplinary, systems-oriented approach to research – Sustainability and Resource Growth Partnership and Collaboration
