Document Management Reference Model - Goals Provide a framework which shows how document management systems fit into a corporate information technology infrastructure Show how document repository integration and interoperability can be handled seamlessly with document management standards Illustrate how extensible services like security and directory services are provided through the existing enterprise infrastructure Give a consistent way to illustrate the differences between document management standards 2/19/99

Reference Model Definitions

Presentation/Application Layer Document-related applications Desktop applications Enterprise applications Native document management clients Scan/Print services Presentation layer Provides user interface ODMA 1.0 providers and other extensible presentation frameworks are at this level 2/19/99

Middleware/API Layer Defines common interfaces for services provided by document repositories DMA and CORBA IDL for DM are examples Proprietary API in some cases (e.g., in ODMA model) Provides a uniform access model for document repositories Repository registration and location Cross-repository search 2/19/99

Middleware/API Layer May provide transparent object distribution across network boundaries (e.g., via CORBA or DCOM) Alternatively, may intercede only in limited ways, and otherwise allow client calls to pass through untouched E.g., non-distributed DMA middleware handles repository registration and location, and cross-repository search, but allows all other functions to pass directly from client to service provider 2/19/99

Service Provider Layer Provides services for repository usage and administration Different DM vendors can plug in their DM repositories within a standards-based enterprise-wide framework Administration distinguished from usage; administration currently not standardized 2/19/99

Corporate Information Technology Infrastructure DM model builds on existing enterprise IT infrastructure services -- transport, object management, network management, security, directory, database, work flow, OS E.g., DM vendors could build on CORBA or DCOM for distributed object management, rather than build a proprietary infrastructure 2/19/99

Network Services Network services provide for communicating with document repositories in a networked environment Allows clients to communicate with document repositories, and to request and receive information from service providers 2/19/99

Network Services Provides flexible transport mechanism by which documents are transferred from document repositories to clients Application-level protocols like WebDAV provide high-level functions like locking, property management, etc. on top of basic transport protocols 2/19/99

Object Management Services Provides transparent object distribution, e.g., via CORBA, DCOM, or RPC Gives the clients uniform access to distributed, heterogeneous information resources and services Supports object lifecycle management, transactions, etc. -- e.g. CORBAservices, MTS, COM IUnknown 2/19/99

System & Network Management System Management: Manages software installation, configuration, & upgrades across an enterprise Network Management: Monitors, manages, & controls network topology and nodes 2/19/99

Security & Directory Services Security Services: Enforces access controls and user authentication Directory Services: Provides service for locating network resources, nodes, users, groups, etc. 2/19/99

Operating System Services Provides fundamental services for memory allocation and management, file systems, device management, network connectivity, ... 2/19/99

Relationships Between Elements In the front document management plane, physical proximity of layers implies that those layers interact via objects and method calls. Likewise, the proximity of the document management plane to the IT infrastructure planes implies interaction. However, the positioning of the infrastructure layers in the diagram is arbitrary; juxtaposition does not necessarily imply a relationship between infrastructure layers. Interactions among the elements of the IT infrastructure are beyond the scope of this reference model. 2/19/99
