The CHAIN-REDS virtuous cycle Sustainability Access Inclusion Rome – 24 January 2014
Largest e-Infrastructure related knowledge base. Information both from the survey and othersources for more than half of the countries of the world The CHAIN Knowledge Base(www.chain-project.eu/knowledge-base)
Identifystandards to easilygather and accessboth Open Access DocumentRepositories (OADRs) and Data Repositories (DRs) • Build a demonstrator to easy visualise and accessOADRs and DRs (both geo-views and tab-views) • Correlate OADRs and DRs to create linked data and discover new knowledgethroughsemanticenrichment of metadata • Promote Data Infrastructurestandards and identify new OADRs and DRs from regionsaddressed by the project (Africa, Middle-East and GulfRegion, Latin America, China, India, Far-East Asia) • Populate the demonstrator with these new repositories, addthem to the semanticenrichmenttool, and set-up atleasttwo use-cases from differentdomains CHAIN-REDS program for Data Infrastructures Rome – 24 January 2014

Linked data semantic search (www.chain-project.eu/linked-data) Preliminary ! New knowledge discovery!
A step further: parallel search (“mashing up” semantic web repositories)
Data Infrastructures are becoming an essential component of e-Infrastructures • Nextyears’ biggestchallengewill be to uniquely correlate scientificpapers with data used to writethem with applicationsused to analysethem so to be able to go across the knowledgepathboth ways • Semantic-web and linked-data technologies can play a major role in thiscontext and CHAIN-REDS aims to promotethesestandards in the targetedregions Summary and conclusions Rome – 24 January 2014
