About the table

Empowering scientific communities with tools that enable them to make use of  European Grid Infrastructure services is important for the successful engagement of EGI with new users. Portal technologies play an important role within this respect. Portals can eliminate barriers of e-Infrastructure access, portals can seamlessly integrate grids and the web. Because of their strong relation to users, portals are typically geared to specific users, applications, scientific use cases. Several national and community-specific teams and projects offer portals and "portal builder technologies" in EGI. With such a diversity it can be difficult to make a decision on which portal to use as a scientist, which portal builder technology to use as a portal developer.


EGI responded to this need with the setup of a "portal technology comparison table". The table provides a review of existing and reusable portals, portal developer frameworks, portlets and components that exist within EGI. The table helps scientific communities and their software teams identify solutions that best meet their needs and should be considered when accessing or building portals.

The questions that are used within the table to describe and compare the different portals and portal frameworks have been defined through an open process during December 2011 - January 2012.

Questions

This section lists the questions that are used within the to describe and review portals and portal builder frameworks that exists for users of the European Grid Infrastructure. New entries can be added to the table as described on that page.


Basic information

1. Name of the portal (P-GRADE Portal, WeNMR Portal)
    
2. Webpage of the portal
   
3. The described portal is:   
   
* a complete portal (can be used “as it is”, its features cannot be customised)   
   
* a portal framework (can be used “as it is”, and additionally features can be added, removed, changed)   
   
* a portal component (for example a portlet, or a library for portal developers)   

Detailed information

4. Is the portal open source? Under what license?   
   
5. Who are the potential users of the portal and what kind of skills do they need to have? (e.g., which programming language skills are needed if the technology is for portal developers)   
   
6. What are the key features of the portal? (e.g., list of portlets in case of a complete portal)   
   
7. What are the distinguished features of the portal? (features that make this technology different from similar solutions)   
   
8. Which EGI services are accessible through the portal? (e.g., middleware services - gLite, ARC, Globus, Unicore; other services like a Helpdesk, a Requirements tracker, etc.)   
   
9. What is the supported security model and technology?   
  
10. Does the portal support workflow execution? If yes, for which workflow system?   
   
11. Is the portal available for download, or is it hosted as a service? 




Adding a new entry

New entries can be added to the table through this [LINK online survey]. The survey consists of two sections to collect basic and more detailed information about the technology to be added. If you wish to read the survey questions before filling the form please consult with this page. The survey is managed by the EGI.eu User Community Support Team, who validate the received information and add entries to the below, publicly accessible table. If you register your portal in the table please also consider registering it in the EGI Applications Database.

Changing an entry

Please email the requested change to the EGI.eu User Community Support Team - ucst@egi.eu.
