2. Project facts

3. 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.

16. 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 3 Type a Service
URL
Step 4 Type a Method as an
interface routine of Service

17. Plan II: Scaling-up and integration
by parameter sweep workflows + remote API

18. Plan III: involve IT resources from citizens
(volunteers) similarly to the KOPI service

(AAI) Authorization and Authentication Infrastructure
• 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
