Content management

I. Foundations of content management

- Why we have to manage content - What is CMS?

II. How do CMS work?

- Technical infrastructure

How many authors do you have?

How many items does each author create or change per month?

Ex: news, press releases, short tidbits, calendar events, articles 3 authors @ 5 items a month: 15 updates a month; 180 per year 5 authors @ 10 items a month: 50 updates a month; 600 per year 100 authors @ 12 items a month: 1200 updates a month; 14,400 per year

If the number of authors increases and they post the same amount of content, the number of updates increases

Factors that drive CMS

The number of pages on commercial, academic, and government sites continues to increase Users are becoming more demanding and sophisticated People in the organization want changes, updates, and revisions This causes bottlenecks on page production Slowdowns can lead to stale content and inconsistency An unintended consequence of the slowdown is that it ’ s easier for them to absolve themselves of responsibility for the site Technology changes the way an organization creates and manages content

The advantage of CMS

Content management applies technology to automate the most tedious parts of the old school approach It defines a system for separating site design from the server code The server code is kept separate from the content A CMS provides the means and the opportunity to make a site manageable It will change the workflow of the web team It should result in cost and time savings over time

What is a Content Management System (CMS)?

It refers to products that offer the basic technical infrastructure for developing, organizing and publishing content Three main tools:

Asset management interface Used to create and manage content Repository Used to store content Template engine Used to publish content

A wide range of content will be published using the CMS:

Simple pages Complex pages, with specific layout and presentation

Dynamic information sourced from databases, etc Training materials Online manuals (policy & procedures, HR, etc) General business documents Thousands of pages in total Extensive linking between pages

What do CMS do?

CMS automate the process of creating, publishing, and updating Web site content

They make maintaining and updating the content of a site easier

Content contributors have ability to manage their own content

CMS usually have three components

A front-end editor for inputting content A back-end system for storing the content A template mechanism to get the content onto the site

A good CMS will support

Content creation

Integrated authoring environment: a seamless and powerful environment for content creators Easy access to the full range of features of the CMS

Separation of content and presentation

A strict separation allows publishing to multiple formats Authoring must be locally style-based, with formatting applied during publishing

Multi-user authoring

There must be good version control and tracking

CMS supports

Content control

Single-sourcing (content re-use) A single page (or even paragraph) can be used in different contexts, or by different user groups

This allows managing of different platforms (intranet, internet) from same content source Metadata creation Capturing metadata (creator, subject, keywords) is critical Powerful linking Authors create stable cross-links among pages

Content management

Security

Adequate security levels and audit trails must be in place to protect integrity of content Integration with external systems A CMS will only be successful if it can be cleanly integrated with existing business systems Reporting It must provide an extensive range of reports, for users and administrators

CMS supports

Publishing

Stylesheets

Final appearance is controlled through the use of stylesheets Page templates Specifies overall page layout with a non-technical interface Extensibility Allows integration of code to provide additional publishing functionality

CMS supports

Presentation

Usability

The system should produce pages that have ease of use, learnability and efficiency Accessibility It must conform to W3C Web Accessibility Initiative and other relevant standards Cross browser support The pages must be viewable in all major web browsers

CMS supports

Presentation

Speed

Page size must be limited to ensure that load times are acceptable for users Valid HTML All pages must conform to the current HTML specification Metadata All pages must provide sufficient metadata to allow effective indexing and searching
