Web Portal User guide

The DIRAC Web portal is a user friendly interface allowing users to interact with the DIRAC services. It can be easily extended by particular VO or it can be integrated into some other portal.

Terms:

Application

A web page called application in the new portal, for example: Monitoring, Accounting, Production Management.

Desktop

It is a container of different applications. Each application opens in a desktop. The desktop is your working environment.

State

The State is the actual status of an application or a desktop. The State can be saved and it can be reused. A saved State can be shared within the VO or between users.

Theme

It is a graphical appearance of the web portal. DIRAC provides two themes: Desktop and Tab themes. Both themes provide similar functionalities. The difference is the way of how the applications are managed. The “Desktop theme” is similar to Microsoft Windows. It allows to work with a single desktop. The “Tab theme” is similar to web browser. Each desktop is a tab. The users can work with different desktops at the same time.

Concepts:

Two protocols are allowed: http and https. http protocol is very restricted. It only allows to access limited functionalities. It is recommended to the site administrators. The state of applications or desktops can not be saved. https protocol allows to access all functionalities of DIRAC depending on your role (DIRAC group). The state of the application is not saved in the URL. The URL only contains the name of application or desktop. For example: https://lhcb-portal-dirac.cern.ch/DIRAC/s:LHCb-Production/g:lhcb_prmgr/?view=tabs&theme=Grey&url_state=1|AllPlots

Format of the URL

  • Tab theme:
Format of the URL when the Tab theme is used:
  1. https://: protocol
  2. lhcb-portal-dirac.cern.ch/DIRAC/: host.
  3. s:LHCb-Production: DIRAC setup.
  4. g:lhcb_prmgr : role
  5. view=tabs : it is the theme. It can be desktop and tabs.
  6. theme=Grey: it is the look and feel.
  7. &url_state=1: it is desktop or application.
