Use case

Motivation

Encourage the creation and use of collaboration clients which interoperate with integrated collaboration platforms and standalone collaboration services, across enterprise boundaries

What is ICOM?

Integrated Collaboration Object Model (ICOM)for Interoperable Collaboration Services

= framework for integrating a broad range of domain models for collaboration activities in an integrated and interoperable collaborative work environment

Specifies a set of concepts in a collaboration environment, in terms of class and property definitions

The model

Based on existing standards

Modular Extensibility

Focus

ICOM Core

ICOM Extensions

ICOM Core

Defines core concepts

HandlesIdentity management

Content management

Directory management

3 complementary branchesSubject

Artifact

Scope

Access control model

Metadata model

ICOM Core

Subject branch

User and identity management

ConceptsUser

Group

Role

Typically the subject of the triple: (subject, privilege, object)

Artifact branch

Content management

ConceptsArtifact

Folder

HeterogeneousFolder

Typically the object of the triple: (subject, privilege, object)

Scope branch

Directory management

Concepts containers of subjects and artifactsCommunity

Access control model

Discretionary Access Control (DAC)Entity level granularity

Role Based Access Control (RBAC)Scope level granularity

Metadata model

ICOM Extensions

Focused on a specific collaboration activity

Extend concepts from Core mostly Artifact and Folder

Extensions can rely on concepts from other extensions

Content model

Represents a piece of data

ConceptsSimpleContent

MultiContent (composite pattern)

Used in Document model

Message model

Document model

Defines a model for version control

are contained in folders

Message model

Defines generic messages used in collaboration

Persistence

OpenICOM java.net projectProvides JPA representation of ICOM

All ICOM Entities can be persisted

StorageRelational

Pluggable connectors

Interoperability

XML Schema representation of ICOM

Allows exchange of data via SOAP services

REST services

Semantic representation

OWL and RDF representations of ICOM
