Édition Coopérative et Large Échelle dans Duplex

Abstract

{\DUPLEX} est un environnement d'édition coopérative pour des utilisateurs connectés sur Internet. La large échelle implique l'hétérogénéité, des délais de communication non bornés et des pannes. Dans ce cadre, les techniques traditionnelles utilisées pour l'édition coopérative dans un réseau local sont inefficaces. {\DUPLEX} propose un modèle basé sur une décomposition du document en parties indépendantes maintenues individuellement par un noyau dupliqué. Le traitement de l'atomicité et du contrôle de duplication devient réalisable puisque confiné à un petit contexte. Les utilisateurs interagissent avec le noyau soit en récupérant une copie locale d'un objet du noyau qu'ils peuvent modifier à loisir dans leur environnement local, soit au contraire en répercutant au niveau du noyau une copie locale. Les communications sont réduites au minimun autorisant une utilisation à large échelle. Le contrôle de concurrence offre des mécanismes optimistes ou pessimistes pour chaque objet individuellement tout en garantissant une cohérence forte (la linéarisabilité).

Worker cooperative

A worker cooperative is a cooperative owned and self-managed by its workers. This control may mean a firm where every worker-owner participates in decision-making in a democratic fashion, or it may refer to one in which management is elected by every worker-owner who each have one vote. Worker cooperatives rose to prominence during the Industrial Revolution as part of the labour movement. As employment moved to industrial areas and job sectors declined, workers began organizing and controlling businesses for themselves.

Consumers' co-operative

A consumers' co-operative is an enterprise owned by consumers and managed democratically and that aims at fulfilling the needs and aspirations of its members. Such co-operatives operate within the market system, independently of the state, as a form of mutual aid, oriented toward service rather than pecuniary profit. Consumers' cooperatives often take the form of retail outlets owned and operated by their consumers, such as food co-ops.
