Integrated Digital Conferencing

indico an european project
INDICO, an European Project

Issues recognized by European Commission who finance InDiCo:

  • Long term archiving of meetings material
  • Enlarging access to scientific conference content
  • Integrating multimedia into conference web archives
  • Reducing conference organization cost

The European Solution for managing and saving conference content in long term

indico project resources
INDICO Project Resources
  • 26 people involved
      • About 13 full time
  • 2 years project :
      • From May 2002 to end April 2004
  • 1.6 M euros invested
  • 5 institutes:
      • Italy: SISSA, University of Udine
      • Holland: TNO TPD, University of Amsterdam
      • CERN

three major components
Three Major Components
  • Archives

Traditional conference material and new increasing

multimedia content must be preserved

  • Video and Audio toolkits

Content captured during events can be analyzed to provide better

rendering and richest search capabilities

  • Conference Management Software

From announcement to proceedings, InDiCo software proposes a

range of solutions to manage an event

some existing products ii
Some existing products (II)
  • Commercial products
    • Mainly hosting is proposed
    • Mostly service oriented, with “manual” intervention like hotels booking, paper shipping, etc
    • Targets are large conferences. Not convenient for one day workshop
    • No multi-conference features
    • High Cost: each event is charged and additional fees often asked to participants
    • Long Term problem: longevity of the web site requires to pay every year. Strong dependency on ‘small’ company

JY Le Meur

some existing products iii
Some existing products (III)
  • Freeware products
    • Very basic features proposed and poor web interfaces
    • Incomplete
    • No much flexibility in the design
    • Aiming at single event management
    • Very little experience: not much used so far by conference organisers
  • With >10,000 agendas of events stored in CERN Agenda Application, we had an interesting starting point…

JY Le Meur

major issues
Major Issues
  • Variety of document types related to conferences
  • Variety of actors involved in Conferences
  • Difficulty in management of multimedia material
  • Richness of conference types (processes, structure, size, management, workflow…)

Reminder of what is a conference ! (I)
  • Many people…

Web site users

  • And more ! (sponsors, travel coordinator, publishers…)

Conferences

Categories

What is a conference ! (II)

> Call for Material

> Material Submission

  • Lot of “objects”…

Talks

> Material Selection

Categories contain many conferences

that contain many sessions that contain many contributions that may contain many talks with many attached material…

> Program Setup

> User Registration

> Web Site Management

> Electronic Proceedings

> Long term archive

Lot of processes

development process
Development process
  • Based on the Unified Software Development Process light weighted and adapted
    • 5 iterations defined based on the use cases
    • Activities & results:
  • Implementation and use of several prototypes for validation and ensuring quality and scalability

technology i
Technology (I)
  • UML for technical documentation (development models)
  • Python
    • General purpose scripting language
    • Supports the OO paradigm
    • High-level  less developing time
    • Java or C/C++ components can be easily integrated
    • CDS has good experience
    • Easy to learn for potential contributors

JY Le Meur

technology ii
Technology (II)
  • Persistence based in ZODB (Zope Object Database)
    • Object Oriented database implemented in Python
    • Transparency: no need for explicit read/writes of the objects
    • Fits very well with our complex object model
    • Performance and scalability proved as it is the DB engine of Zope
  • Apache+mod_python as application server
  • The web interface is built using pure HTML

JY Le Meur

technology iii
Technology (III)
  • OAI (Open Archive Initiatives) for ensuring connectivity and integration with other services
    • Standard protocol for information exchange between digital libraries
    • Allows to expose conference data
    • Data provider  record=conference
    • Allows other systems to fetch conference data and build services over it
    • Simple mechanism  XML over HTTP
    • INDICO offers Dublin Core and a home made metadata formats

JY Le Meur

final remarks
Final remarks
  • Released under open source license
  • Easy packaging & deployment
  • Multiplatform (tested on Windows and Linux)
  • Integration with other systems  OAI
  • Already hosts more than 20 conferences at CERN and it is running in many institutes
