A tool for enabling user collaboration in Science Gateways

1. Apache Airavata Sharing Service:
A Tool for Enabling User Collaboration
in Science Gateways
Supun Nakandala
Indiana University

3. Science centric user environments
that enable broader and more
effective use of scientific computing
resources, applications, and data.
Science Gateways ?

5. How can we make Science
Gateways like Google Drive?
(Box, DropBox, etc…)

10. Gateway
Do Science
Collaborate

12. User1: Grant READ access to Group1 on
Experiment1 and its children

13. User1: Grant READ access to Group1 on
Experiment1 and its children
User1: Grant PERMISSION_GRANT access
to User3 on Project1 and its children

14. Owner: User1
Group1

15. Owner: User1
Group1
User1: Grant Access to
Group1 on Resource
User1: Grant Access to
Group1 on Application

16. IU Group
SEAGrid Admin: Grant Access to IU_Group
on BigRed11

17. Requirement 1
Grant and revoke
permissions
Requirement 2
Check permission for a given
entity
Requirement 3
Browse and search within all
accessible entities
Requirement 4
Efficient and generic
implementation
System Requirements

19. Collaboration Aspects

20. Sharing Service
Generic first-class component to handle
diverse user collaboration aspects

21. Sharing Service
Generic first-class component to handle
diverse user collaboration aspects
Group Management, Registering Entities, Definition and Enforcement
of Sharing Rules

23. Grant and revoke permissions

24. Grant and revoke permissions
Grant User1 READ access
on Project1

And other possible combinations…

32. Browse/search entities for a
user
Get entities of type Experiment where User1 has READ access
and Experiment.name Like ‘Gaussian’
