Enterprise Content Management

Enterprise content management (ECM) is a formalized means of

organizing and storing an organization's documents, and other

content, that relate to the organization's processes. The term

encompasses strategies, methods, and tools used throughout the

lifecycle of the content.

What is a repository? - You use it!!!● Some simple examples:

○ SMTP servers○ Google Drive○ Dropbox

● Some Open Source repository implementations:○ exoJCR○ Apache JackRabbit

● Some Open Source ECM systems for critical usage:○ Alfresco○ Nuxeo○ Hippo

What is a repository? - Model

● different point of view of how managing data○ no more Relational databases (ER)

● based on the JCR Repository Model (JSR-283)○ workspaces○ identifiers○ users ○ nodes and node types (contents)

■ properties and property types■ associations (shared nodes)

What is a repository? - Model

● A node is a generic content stored in a repository○ type○ properties○ associations○ binary streams (optional)

■ renditions■ text document■ Video■ Image

Why use a repository?● you can scale out easily

● storing very large amounts of data

● storing simple data structures, such as simple JSON

● looking up data by keys rather than using queries

● searching for data based upon relevance

● evolving schemas and/or data structures

● caching data in-memory for performance

Alfresco● Open Source ^__^● Community Edition

○ new features○ wide community support

Alfresco - Concepts

● Aspects○ an aspect is a tag that can decorate contents

■ adding new properties■ adding new behaviors (trigger)

● WebScripts○ create your own REST API

● Collaboration & Security

Alfresco - Concepts - Spaces● Spaces

○ contains contents○ rules for executing actions

■ event■ actions

Alfresco - Concepts - Spaces● Spaces can be used for implementing a specific ECM

design pattern such as Drop Zones
