Project facts

agINFRA in a few sentences

① Based on a linked open data architecture harmonizing semantics and ontologies.

② Aggregating data of existing systems and taking advantage of advanced Grid services and infrastructure.

③ Devised for scalability and maximum interoperability by adapting existing widely used components.

④ Fostering diverse communities of heterogeneous providers and users.

⑤ Providing researcher-centric services.

agINFRA Science Gateway

Architecture of gUSE

First demo application

AgroVOC

AgroTagger

Job executable

JDL for setting requirements

Execution of AgrovocTagging application

Plan I: New jobs

to be integrated as webservices in the workflow

Step 1 Select Service as Job interpretation class

Step 2 Select Type of Service to be understood

Step 4 Type a Method as an interface routine of Service

Step 3 Type a Service URL

Plan II: Scaling-up and integration

by parameter sweep workflows + remote API

SZTAKI DG Client

SZTAKI Desktop Grid (DG) Server

SZTAKI DG Client SZTAKI DG Client

Plan III: involve IT resources from citizens

(volunteers) similarly to the KOPI service

(AAI) Authorization and Authentication Infrastructure

Authorization

Authentication

• Identity Federation

– Identity federation is federating an entity's identity to facilitate single

sign-on or cross-domain single sign-on

• Identity Providers (IdP)

– An authentication module which verifies a token authorizing a user to

access a service

• Service Provider

– Entity providing services to principals or other system entities

Gateway a trusted service provider
