NEES Data Goals

Aligned with NSF Data Management Plan (DMP) requirements* All research data and documentation will be archived

Types of data and other materials to be produced during project Archived data will be of high quality

Standards to be used for data and metadata format and content Archived data will be accessible and shareable

Policies for access and sharing Archived data will be re-usable

Policies and provisions for re-use Archived data will be preserved

Plans for archiving and preservation of access to them* http://www.nsf.gov/pubs/policydocs/pappguide/nsf11001/gpg_2.jsp#dmp

Data Archiving

Who research team, site personnel, curator, NEEScomm

What sensor measurements, sensor calibrations, observations, analyses, numerical simulations,

images and videos, reports (including publications and presentations), logs

When Dates are stated in the Data Sharing and Archiving Policies (1 month, 6 moths, 12 months) For as long as the data are useful ~ indefinitely ~ for 20 years

Where Project Warehouse http://nees.org/warehouse/welcome

Why increases researcher’s impact saves work, time, money good practice advances science

Information Package

Information Package – discoverable through descriptive information

Content Information - the original target of preservation - consists of

Content Data Object (bits) Representation Information – needed to make object

understandable to the community (record)

Preservation Description Information - information needed to preserve the Content Information

Provenance Context Reference (Identification) Fixity – protect the CI from undocumented alteration Access rights

Quality Assurance

Data need to be understandable Standards Seeing standards

Research teams Professional standards Team guidelines for data management NEEScomm requirements

NEES Sites Certifications Professional standards Local guidelines (naming conventions, etc.)

NEES Data Repository OAIS PREMIS Dublin Core Documentation and metadata requirements

Curation interactive and iterative exchange assessment of technical quality of data and relevant

documentation

Access and Sharing

Time Unprocessed data – within 1 month Corrected data and documentation – within 6 months Data made PUBLIC within 12 months

Conditions for access and sharing (Let others know that they can use your data) Open Data

Data Re-Use

Use of known, tested, and open formats is key to the success of any future attempt to use data

Data Use - Using research data for the current research purpose/activity to infer new knowledge about the research subject.

Data Re-use - Using research data for a research purpose/activity other than that for which it was intended.

Data Purposing - Making research data available and fit for the current research activity.

Data Re-purposing -Making existing research data available and fit for a future known research activity.

Supporting Data Re-use - Managing existing research data such that it will be available for a future unknown research activity.
