2. Outline
Digital Enterprise Research Institute www.deri.ie
 Motivation
 The model
 ICOM Core
 ICOM Extensions
 Features
 Persistence
 Interoperability
 Semantic Representation
 Use case

3. Motivation
Digital Enterprise Research Institute www.deri.ie
Encourage the creation and use of
collaboration clients which interoperate
with integrated collaboration platforms
and standalone collaboration services,
across enterprise boundaries

4. What is ICOM?
Digital Enterprise Research Institute www.deri.ie
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

5. The model
Digital Enterprise Research Institute www.deri.ie
 Based on existing standards
 Modular
 Extensibility
 Focus
 ICOM Core
 ICOM Extensions

6. ICOM Core
Digital Enterprise Research Institute www.deri.ie
 Defines core concepts
 Handles
 Identity management  Access control model
 Content management  Metadata model
 Directory management
 3 complementary branches
 Subject
 Artifact
 Scope

7. ICOM Core
Digital Enterprise Research Institute www.deri.ie

8. Subject branch
Digital Enterprise Research Institute www.deri.ie
 User and identity management
 Concepts
 User
 Group
 Role
 Typically the subject of the triple:
(subject, privilege, object)

9. Artifact branch
Digital Enterprise Research Institute www.deri.ie
 Content management
 Concepts
 Artifact
 Folder
 HeterogeneousFolder
 Typically the object of the triple:
(subject, privilege, object)

10. Scope branch
Digital Enterprise Research Institute www.deri.ie
 Directory management
 Concepts – containers of subjects and artifacts
 Community
 Space

11. Access control model
Digital Enterprise Research Institute www.deri.ie
 Discretionary Access Control (DAC)
 Entity level granularity
 Role Based Access Control (RBAC)
 Scope level granularity

12. Metadata model
Digital Enterprise Research Institute www.deri.ie
 Annotations on objects
 Concepts
 Markers
 Categories
 Tags

13. ICOM Extensions
Digital Enterprise Research Institute www.deri.ie
 Focused on a specific collaboration activity
 Extend concepts from Core
 mostly Artifact and Folder
 Extensions can rely on concepts from other
extensions

14. Content model
Digital Enterprise Research Institute www.deri.ie

 Concepts
 SimpleContent
 MultiContent (composite pattern)
 Used in
 Document model
 Message model

15. Document model
Digital Enterprise Research Institute www.deri.ie
 Defines a model for version control
 Concepts
 Document
 WikiPage
 Documents
 can contain a content
 are contained in folders

16. Message model
Digital Enterprise Research Institute www.deri.ie
 Defines generic messages used in collaboration
 Concepts
 Message
 UnifiedMessage
 Messages
 Can contain a content
 Are contained by HeterogeneousFolders

17. AddressBook model
Digital Enterprise Research Institute www.deri.ie
 Contact information management
 Concepts

– Specialized folder
 PersonContact
– Specialized artifact

18. Presence model
Digital Enterprise Research Institute www.deri.ie
 Represents a watchable state of an actor
 Concepts
 Presence
 Activity
 ContactMethod

19. TaskList model
Digital Enterprise Research Institute www.deri.ie
 Task management
 Concepts
 TaskList
– Specialized folder
 Task
– Specialized artifact

24. Representations of ICOM
Digital Enterprise Research Institute www.deri.ie
 Persistence
 JPA
 Interoperability
 XML
 Semantic representation
 OWL
 RDF

25. Persistence
Digital Enterprise Research Institute www.deri.ie
 OpenICOM – java.net project
 Provides JPA representation of ICOM
 All ICOM Entities can be persisted
 Storage
 Relational
 Pluggable connectors

26. Interoperability
Digital Enterprise Research Institute www.deri.ie
 XML Schema representation of ICOM
 Allows exchange of data via
 SOAP services
 REST services

27. Semantic representation
Digital Enterprise Research Institute www.deri.ie
 OWL and RDF representations of ICOM
 Modular like the model
 Benefits
 Access to the growing amount of Linked Data available
 Inference
 Reasoning

28. A use case
Digital Enterprise Research Institute www.deri.ie
 Integration of ICOM in SMW
 SMW Calendar module which uses the ICOM
Calendar extension model
