Metadata Management and Data
Continuum - Vision
• Metadata management and mining
– Enhance and deploy at the participating Ris metadata catalogues
– Connect as one seamless resource.
– Use this unique tool for a better understanding of the
users need and trends (Instrument Setup, Sample
Environment, …).
Federated data catalogue
 ICAT as a candidate ? At least for X-Ray and Neutrons
 ICAT is a data/metadata catalogue



store/search metadata
ensure data policies
access via a set of API
separates data description from data storage
federated across multiple institutes.
 Is sample S already analyzed at temperature T under
Pressure P ... ?
 Where? Which instrument? where are the data located?
Data mining
 What are the most studied samples?
 Where are the trends?
 What type of Instruments/techniques should be
developed further?
 Help to better understand the behaviour/needs of our
users
 ...
If the data mining tool could take into account the
metadata, the users and the publications it would
become a invaluable strategic analysis tool.
WP 17 - Data Continuum - Vision
Aim for better sustainable links, traceability
an transparency for the whole chain of
experimental science.
Scientific Idea – experimental data - Publication
DOI implementation
• Provides a sustainable standard for the formal
identification and retrieval of the datasets
• Standard already well established in
libraries/journals
• A major initiative has emerged in Europe for
science http://www.datacite.org/
• Help to seal the link between publication and
datasets
What should happen before Oct 2012
• MS6 - Proposed Metadata Catalogue Architecture Document
– Harvest RIs requirements
– T1 Evaluate and adapt metadata catalogues according to the RIs
requirements;
– T2 Prototype of data mining on metadata services;
• MS7 - Proposed Data Continuum Architecture Document
– T4 Identify the PI system which best fits the needs of the partners;
– T5 Elaborate a data publication process satisfying data policies of the
participating RIs;
– T6 Implement the persistent Identifier technology;
