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

CORBA ORBs could also be used to distribute the middleware and/or service provider layers of the DM reference model

Reference Model Definitions

2/19/99 19


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 20


Defines common interfaces for services provided by document repositoriesDMA and CORBA IDL for DM are examplesProprietary API in some cases (e.g., in ODMA

model) Provides a uniform access model for

document repositoriesRepository registration and locationCross-repository search

2/19/99 21


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 22

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 23


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 24

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 25

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 26

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 27

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 28

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 29

Operating System Services

Provides fundamental services for memory allocation and management, file systems, device management, network connectivity, ...

2/19/99 30

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.
