Architecture

KernelIt is a unified environment where content is

stored, accessed and secured

Repository Infrastructure

Repository Services

Security Services


7/44

Content Objects

Content is stored in the repository as an object

Objects comprise three parts:

Content Assets or Source data

Represent the core information stored in its native format.

Content Attributes or Metadata

Describe the content assets with descriptors such as

keywords, owner, version, links and creation date.

Methods or Operations

Instructions to be performed on the content assets, such as

transform, notify and display.


8/44

Repository Infrastructure

Documentum repository consists of

four main components:A file store containing the

content assets.

Attribute tables within a

relational database.

Full-text Indexes (Text basedcontent assets)

All words of the content assets

stored within the repository.

All keywords and other content

attributes (or metadata) that

describe the content assets.Directory Services

A networked service fromwhich info can be looked-up and

retrieved about available

resources, including info about

groups, individuals, printers etc.


9/44

Repository Services Content Server

The repository can only be accessed via the Content Server.

It provides two storage-specific services:

Content Storage Servicesadd a storage policy engine to the

Documentum repository that enables event triggered, ad hoc,and batch execution of storage allocation and migration

polices.

Content Services for EMC Centra is the bridge between

Documentum repository and Centra, an EMC content-addressed storage (CAS) system that ensures fast, easy,

online access with assured content authenticity and petabyte

scalability.


10/44

Repository Services - Content

Documentum repository stores content in a

consistent manner regardless of content

type, file size or file format. Content types

include but are not limited to the

following:

DocumentWeb page

XML document

Report

Executable

Engineering drawingScanned image

Audio or video file

Thumbnail file

Corporate Record


11/44

It uses LDAP to synchronize user and group identities enterprise-

wide.

Assigns authorization rules through access control lists (ACL), which

are automatically applied to all repository objects when the objects are

created.

Every Operation performed by the Documentum Repository can be

recorded in an auditable record.

Security Services Information Rights

Management Services

IRM services extend the security

and access controls on

documents and other types of

content beyond the boundaries

of content platform.

IRM Services secure

RovingContentthat require persistent

protection across the network and

wherever the content is located and

stored.

IRM services add on IRM policyserver to the enterprise information

environment to secure the content

that is no longer managed by

documentum content server

Application Services GroupProvides various application-

level services for organizing, controlling, sequencing and

delivering content to, and from the repository.

Compliance Services

Content Services

Process Services


15/44

Compliance Services Retention Policy Services

Compliance Services provide capabilities for retaining content

and managing content as records. These are

Retention Policy Services

Records Manager

RPS specify and enforce the retention of objects in the

documentum repository by attaching one or more retention

policies to the objects. The objects cannot be changed or deleted

for the duration of the retention policy.

RPS enhances the standard documentum controls along threeimportant dimensions:

Notifications

Auditing

Reporting


16/44

Compliance Services Records Manager

Records Manager architecture

provides recordkeeping functionality as

services that can be used for electronic

and physical records alike.

Records Management capabilities

support electronic documents, e-mail

and paper based documents as managed

records. These capabilities leverage the

complementary offerings of the overall

documentum platform

Records Manager leverages RPS andthe capabilities of the documentum

platform to provide records management

capabilities in a modular fashion.


17/44

Content Services Library Services - Versioning

When a document is modified it is stored in the

repository as a new version

Each version is represented by a unique set of

properties and content

Each version has a unique version number

The initial version number is 1.0

By default, users access the most recent or current

version

Check-in/Check-out capabilities ensure users with

editing privileges do not overwrite one-anothers

versions or make incompatible updates.


18/44

A Content file can be associated with one or more renditions

A rendition is a read-only representation of the content that

differs from the original in some way i.e. different format,

language, resolutions etc.

A Content file and its renditions are managed as a single document

in the repository.

Content Service Library Services - Renditions


19/44

Content Services Workflow Services

Documentum workflow automates business activities and policies

for repository content.

A workflow is defined by a model, the sequence of steps that

comprise the process, and the actions that must occur at each step.

A workflow can be serial with activities occurring one after another,or parallel, with all activities occurring simultaneously


20/44

Content Services Lifecycle Services

Documentum platform defines, maps and implements flexible

content lifecycle rules according to the business policies established by

the enterprise.

Lifecycle services assign a lifecycle stage to the content object, and

then manage the objects transition from one stage to another.

Each content object has only a single lifecycle

Documentum API

Documentum Foundation Classes (DFC) is the published and

supported programming interface for accessing the functionality ofthe documentum Platform. It provides Java and COM class libraries

that expose the functions that drive the documentum platform.

Documentum Foundation Services (DFS) are an SOA development

framework and API. They are based on web services, and designed tosupport interoperable machine-to-machine interaction over a network.

Documentum Platform also includes Business Framework Object

(BOF). BOF provides a framework and a methodology to develop

reusable business logic components called Business Objects. This

framework is built into DFC and accessible from applications written

using DFC. It can implement business logic in reusable business

object components that can be plugged into middle-tier or client

applications.
