Science Paradigms• Thousand years ago:

science was empirical describing natural phenomena

• Last few hundred years: theoretical branch

using models, generalizations

• Last few decades: a computational branch

simulating complex phenomena

• Today: data exploration (eScience)

unify theory, experiment, and simulation

What is the problem with data?

analysed

synthesised

interpreted

are

become Information

is

published

becomes Knowledge

Publication

… is accessible

… is traceable

… is lost!Data

Consequences for Libraries

• Scientific Information is more than a published article or a book

• Libraries should open their catalogues to this non-textual information

• The catalogue of the future is NOT ONLY a window to the library‘s holding, but

• A portal in a net of trusted providers of scientific content

Consequences for Libraries

We do not have it

BUT

We know where you can find

And here is the link to it!

Vision 2015

• But what has this to do with metadata

Use Case1: Searching and Displaying

Catalogue metadata

Use Case 2: Searching and Displaying

Discipline related metadata

Use Case 2: Citation

Citability of research data

• High visability of the data • Easy re-use and verification of the data sets. • Scientific reputation for the collection and documentation

of data (Citation Index)• Encouraging the Brussels declaration on STM publishing • Avoiding duplications• Motivation for new research

The dataset:

Kuhlmann, H et al. (2009):

Age models, iron intensity, magnetic susceptibility records and dry bulk density of sediment cores from around the Canary Islands.

DataCite

DataCite Working Group „Metadata“

• Define a core DataCite metadata set:

• Include complete citation information• Include search information• Include Relations to other objects• Dublin Core compliant• Simple

Status

• Work in progress

• 6 core mandatory elements:• Creator, • Title, • Publisher, • PublicationDate, • Discipline,• DOI

• Optional elements.

• Predefined Vocabularies
