- peer reviewed publication of data

Agenda

Why publish data ... and: What is the problem? Developments in the arena of science policy State of the art and missing elements

ESSD - “Earth System Science Data”, a journal A practical contribution to an emerging genre of

scholarly communication Aims and scope; structure of articles, review criteria

Conclusion

H. Pfeiffenberger; DataCite, Hannover, 2010-06-07 3

ESF / EuroHORCs European Research Area Vision

Publishing data through a peer reviewed journal will help comply with the requirement for quality assured research data

WE WON (Didn’t we?): Data side by side with “output” = articles!

H. Pfeiffenberger; DataCite, Hannover, 2010-06-07 4

Good Scientific Practise – what has changed?

ability to produce data – by orders of magnitude ! (tipping point 1980ies, advent of microcomputers?)

Consider Ozone data from satellites:

Fusco, L., J. Linford, W.J. Som de Cerff, C. Boone, C. Leroy and M. Petitdidier, Earth Observation Applications Approach to Data and Metadata Deployment on the European DataGrid Testbed

Well documentedprocedures

Well definedproducts

Well known instruments

ESA / other gov. agencies as stewards => Elaborate infrastructure

QA by process!

Consider ground based ozone profiles from Antarctica

Ozone soundings (balloon-carried sonde profiles) in the years when the “ozone hole” first developed

balloon data needed for calibration of satellite data and thus, verification of models

The Granularity problem by analogy

At the “Petascale”, where largely homogeneous mounds of data are handled in an industrial fashion, and collated into one super-dataset, comparable to a book holding the work of a (number of) lifetime(s)

At and below the “Megascale”, where large numbers of heterogeneous datasets are handled as in a factory (manufaktur), by a craftsperson or an artisan. They are communicated on demand through mail or via obscure ftp-server, comparable to the letter from scholar to scholar.

There is almost no in-between, yet, to handle the bulk of information at the Mega- to Terascale, which would need to be comparable to the system of academic journals for textual information.

Summary - Outlook - Part I

ESF: “... permanent access to ... quality assured research data”

Aim: Reuse & Reproduce

Digital Longterm Preservation

Persistent (and Open)Access, LicensingQuality Assessment

Data provided and described by researchers

Basic and advanced data infrastructure, provided by ???

Data publishing must provide Required for Data publishing

Estimate of Error and Data Provenance

H. Pfeiffenberger; DataCite, Hannover, 2010-06-07 13

Originality / Uniqueness :

Are the data or methods new - i.e., never measured or described before

Significance:

Is there any potential of the data being useful?

- Usefulness

- Completeness

=> Necessary to KEEP THE LEVEL OF NOISE LOW! <=

Data Quality

The data must be presented easily accessible in a useful format.

Accuracy, methods, instrumentation and processing : state of the art

Review Guidelines

One ozonesonde profile might be enough to calibrate satellite data!

We would not publish it, anyway! (Rather, 426 profiles)Usefulness probably too narrow <= wrong Granularity

Reuse, Citation and Quality Assessment with ESSD

H. Pfeiffenberger; DataCite, Hannover, 2010-06-07 16

Summary - Outlook : Part II

Reward for data publication, by being citable (hopefully, with impact factor)

Quality assured data and data documentation facilitate future reuse

First articles online – first experiences

Special Issue with 20 papers from the CARINA project - oceanic carbon budget - in production

Outlook

Strong, positive response from scientists with high time budget in data production

Development of more specialized manuscript templates and review guidelines for other types of research data
