Web and mobile access to digital repositories Mario Torrisi National Institute of Nuclear Physics – Division of Workshop Commissione Calcolo e Reti dell’INFN – Genoa, 30 May 2013

Outline Genoa - 30 May 2013Workshop Commissione Calcolo e Reti INFN2  Introductory considerations  gLibrary  Architecture  Federated Authentication  APIs  Use cases examples  Desktop  gLibrary browser portlets  Mobile scenario  Earth science: EarthServer SG Mobile  Cultural Heritage: DCH-RP eCSG Mobile  Summary and Conclusion

Introductory considerations (1/2) Genoa - 30 May 2013Workshop Commissione Calcolo e Reti INFN3  Issues: 1. Exponential growth of available digital content  Big Data 2. Complexity of technologies to manage large repositories of data 3. High availability 4. Back-end interoperability 5. Access control 6. Mobile access

Introductory considerations (2/2) Genoa - 30 May 2013Workshop Commissione Calcolo e Reti INFN4  Possible solutions: 1. Federated digital repositories 2. Standard-based middleware to seamlessly manage local storage, grid storage, cloud storage 3. Federated Authentication & fine grained authorization 4. Dedicated Apps

Genoa - 30 May 2013Workshop Commissione Calcolo e Reti INFN5 digital assets  gLibrary is a framework developed by INFN that provides a simple system to store, organize, search and retrieve “digital assets” in repositories built on local, grid or cloud storage  Digital assets:  Digital object + its metadata Hides the underlying technologies to end users

eToken service architecture Genoa - 30 May 2013Workshop Commissione Calcolo e Reti INFN6 Front ends glibrary.ct.infn.it REST API AuthN / AuthZ Science Gateway User Tracking DB Call gLibrary REST API through API Server Gateway Metadata Service Local storage Grid storage Cloud Storage Authorization service Authentication service

Federated Authentication (1/3) Genoa - 30 May 2013Workshop Commissione Calcolo e Reti INFN7  The distributed/cross-domain nature of Grid requires strong security mechanism  Create & maintain certificates, create proxy, update credentials, etc…

 Users would access and use distributed resources as any other web-based service available in their organizations Federated Authentication (2/3) Genoa - 30 May 2013Workshop Commissione Calcolo e Reti INFN8 Grid Security Infrastructure

4. Extract Shibboleth token from response header 1. Get available IDPs Federated Authentication (3/3) (implementation for mobile appliances) Genoa - 30 May 2013Workshop Commissione Calcolo e Reti INFN9 Science Gateway 3. Open WebView glibrary.ct.infn.it REST API Now you can issue any API calls to gLibrary REST API 2. Supported IDPs list

REST APIs (some examples) Genoa - 30 May 2013Workshop Commissione Calcolo e Reti INFN10  Retrieve the tree of types:  /glibrary/mountTree/ /?node=  ex.:  Retrieve the schema of a given type:  /glibrary/metadata/ / /  ex.:  Retrieve an asset’s metadata of a given type:  /glibrary/glib/ / /  ex.:
