in a nutshell gLibrary is a platform developed by INFN that provides a simple yet powerful system to organize, search, store and retrieve “digital assets” in distributed repositories built on Grid/Cloud/local storage infrastructures hides the underlying technical details to the users “digital assets”: digital object + corresponding metadata EGI Community Forum 10-13 November 2015, Bari, Italy

We can use: PostgreSQL MySQL MongoDB Oracle SQL Server Community connectors: CouchDB, SQLite, ArangoDB, etc. gLibrary 2.0 (code and doc) on and EGI Community Forum 10-13 November 2015, Bari, Italy

The Parallel Semantic Search Engine (SSE) The Semantic Search Engine (SSE) is a framework conceived to demonstrate the potential of Open Access Data infrastructures coupled with semantic web technologies to address the issues of data discovery and correlation The framework aims to develop an open access infrastructure for linking scientists and scientific data/information resources The SSE framework has been developed within the CHAIN-REDS project The Semantic Search Engine (code and doc) on and 8 CHAIN-REDS School on Cloud Computing, Catania EGI Community Forum 10-13 November 2015, Bari, Italy
