4 2/19/994 DM Reference Model - A Collaborative Effort :Marilyn Wright, AIIM International :Benny Ong, Boeing Corporation :Fred Siegmund, Chevron :Carl Frappaolo, The Delphi Group :Diane Entner, Eastman SW/Black Forest Group :Chuck Fay, FileNET :Michael Leslie, General Motors :Surendra Reddy, Oracle Corporation :Jean Heminway, Xerox Corporation :Toby Cobrin, XPLOR

5 2/19/995 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

11 2/19/9911 HTTP/WebDAV WebDAV Service Provider WebDAV-enabled Web Server WebDAV in the DM Reference Model WebDAV Client Application HTTP/WebDAV

12 2/19/9912 Generic DMA Distributed Client DMA Client DMA Repository Network Services DMA Middleware DMA Client (skeleton) DMA Service Provider DMA Client Application Network Services

13 2/19/9913 HTTP/WebDAV DMA Middleware WebDAV to DMA Translator DMA Service Provider DMA Repository and Web Server WebDAV and DMA Interoperability WebDAV Client Application HTTP/WebDAV

14 2/19/9914 CORBA and DMA Interoperability CORBA Client DMA Client & Repository CORBA ORB DMA Middleware CORBA IDL to DMA Translator DMA Service Provider Java Client Application CORBA ORB

15 2/19/9915 CORBA and DMA Interoperability :CORBA ORBs could also be used to distribute the middleware and/or service provider layers of the DM reference model :CORBAservices and CORBAfacilities are additional infrastructure that could be leveraged in DMA service provider implementations

18 Reference Model Definitions

19 2/19/9919 Presentation/Application Layer :Document-related applications 4Desktop applications 4Enterprise applications 4Native document management clients 4Scan/Print services :Presentation layer 4Provides user interface 4ODMA 1.0 providers and other extensible presentation frameworks are at this level

20 2/19/9920 Middleware/API Layer :Defines common interfaces for services provided by document repositories 4DMA and CORBA IDL for DM are examples 4Proprietary API in some cases (e.g., in ODMA model) :Provides a uniform access model for document repositories 4Repository registration and location 4Cross-repository search

21 2/19/9921 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 4E.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

22 2/19/9922 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

23 2/19/9923 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

24 2/19/9924 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

25 2/19/9925 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

26 2/19/9926 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

27 2/19/9927 System & Network Management :System Management: Manages software installation, configuration, & upgrades across an enterprise :Network Management: Monitors, manages, & controls network topology and nodes

28 2/19/9928 Security & Directory Services :Security Services: Enforces access controls and user authentication :Directory Services: Provides service for locating network resources, nodes, users, groups, etc.

29 2/19/9929 Operating System Services :Provides fundamental services for memory allocation and management, file systems, device management, network connectivity,...

30 2/19/9930 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.
