Introduction: the InDiCo Project

Page 3: Integrated Digital Conferencing

20 April 2005 JY Le Meur 3

INDICO, an European Project

Issues recognized by European Commission who finance InDiCo:

Long term archiving of meetings materialEnlarging access to scientific conference contentIntegrating multimedia into conference web archivesReducing conference organization cost

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

INDICO Project Resources

26 people involvedAbout 13 full time

2 years project :From May 2002 to end April 2004

1.6 M euros invested5 institutes:

Three Major Components

ArchivesTraditional conference material and new increasing

multimedia content must be preserved

Video and Audio toolkitsContent captured during events can be analyzed to provide better

rendering and richest search capabilities

Conference Management SoftwareFrom announcement to proceedings, InDiCo software proposes a

range of solutions to manage an event

And lot of home-made apps…

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

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…

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…

Speakers

Participants Referees

Chairperson

LibrariansConference Secretary

System Manager

Conference organization

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

Web site users

What is a conference ! (II)

Lot of “objects”…

Talks Categories contain many conferences that contain many sessions that contain many contributions that may contain many talks with many attached material…

Lot of processesINDI ?

Development process

Based on the Unified Software Development Process light weighted and adapted5 iterations defined based on the use casesActivities & results:

Implementation and use of several prototypes for validation and ensuring quality and scalability

User req. Analysis Design Implementation Test

UR-R1 SSR Design modelDeployment model

Sw packageDocumentationDeployment procedures

Automated test suite

Technology (I)

UML for technical documentation (development models)

PythonGeneral purpose scripting languageSupports the OO paradigmHigh-level less developing time Java or C/C++ components can be easily

integratedCDS has good experienceEasy to learn for potential contributors

Page 18: Integrated Digital Conferencing

20 April 2005 JY Le Meur 18

Technology (II)

Persistence based in ZODB (Zope Object Database)Object Oriented database implemented in PythonTransparency: no need for explicit read/writes of

the objectsFits very well with our complex object modelPerformance 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

Technology (III)

OAI (Open Archive Initiatives) for ensuring connectivity and integration with other servicesStandard protocol for information exchange

between digital librariesAllows to expose conference dataData provider record=conferenceAllows other systems to fetch conference data

and build services over itSimple mechanism XML over HTTP INDICO offers Dublin Core and a home made

metadata formats

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
