Targeted regions: Africa, Arab Region, Latin America,
China, India, andFar-East Asia

The CHAIN Knowledge Base(www.chain-project.eu/knowledge-base)
Largest e-Infrastructure related knowledge base. Information both from the survey and other sources for more than half of the countries of the world

CHAIN-REDS program for Data Infrastructures
Identify standards to easily gather and access both Open Access Document Repositories (OADRs) and Data Repositories (DRs)
Build a demonstrator to easy visualise and access OADRs and DRs (both geo-views and tab-views)
Correlate OADRs and DRs to create linked data and discover new knowledge through semantic enrichment of metadata
Promote Data Infrastructure standards and identify new OADRs and DRs from regions addressed by the project (Africa, Middle-East and Gulf Region, Latin America, China, India, Far-East Asia)
Populate the demonstrator with these new repositories, add them to the semantic enrichment tool, and set-up at least two use-cases from different domains

Linked data semantic search (www.chain-project.eu/semantic-search)
More than 22 million resources, almost 600 million triples
Linked data semantic search (www.chain-project.eu/semantic-search)

Preliminary !
New knowledge discovery!

A step further: parallel search (“mashing up” semantic web repositories)

Summary and conclusions Data Infrastructures are becoming an essential component
of e-Infrastructures
Next years’ biggest challenge will be to uniquely correlate scientific papers with data used to write them with applications used to analyse them so to be able to go across the knowledge path both ways
Semantic-web and linked-data technologies can play a major role in this context and CHAIN-REDS aims to promote these standards in the targeted regions
