Fed : Federating data

  written by Guillaume Berthommier and Raymond Ripp

What is Fed

Fed consits of

  • a PHP based website using Html and Javascript
  • a PostgreSQL Relational Database

It allows to manage

  • Teams
    • people
    • workpackages
    • components
    • centres
  • Data
    • within a Gallery of documents
    • or fully integrated in the Relational Database
  • Thematics (or Projects)
    • corresponding to one or several workpackages
    • transversal to the whole database

The Gallery is organized as a hierachical tree of Galleries, each Gallery contains Datafiles and other Galleries.

The people can upload their Datafiles in a Gallery. These data are then especially processed to be integrated in the Relational Database.

Advantages of Fed

  • A unique common set of PHP programs controls all Fed instances.
    • These programs are developped and maintained by Guillaume and Raymond.
    • A copy of them can be used on a distant computer.
  • Each Fed instance has its own private look and feel and relational database as well as specific programs.
    • The web site and pecific programs can also work without Fed

Several Feds can be federated

One interesting point is that several 'independant' Fed can be federated.

  • only the people are known everywhere
  • groups of people are defined independently in each Fed.

This can be easily done if the creation of new users is centralized on the unique FedLord. The information concerning the new user is then transferred to the local Fed especially the Pk which has to be the unique Id of the user.
