How much information is there?Soon most everything

will be recorded and indexed

Most bytes will never be seen by humans.

Data summarization, trend detection anomaly detection are key technologies

What is Content?Content is information that you tag

with data so that a computer can organize and systematize its collection, management, and publishing

Content can be text, images, graphics, video, sound, documents, records etc - or in other words - anything that is likely to be managed in an electronic format.

Content TypesStructured Content

content with inherent structureA tagged bibliographic record

Unstructured Content with no structure, i.e. content

inherent structure, i.e., documents, files, images, reports, emails, Voice mail, phone notes, PowerPoint présentations, Web pages, user groups, etc.

Where It (content) Resides?Distributed across the intranetIndividual desktopsDivision/dept. servers, websitesCompany websites – external,

internalServers: Database, E-Mail, Library

What is CM Systems? A CMS is a tool that enables a variety of

(centralized) technical and (de-centralized) non technical staff to create, edit, manage and finally publish (in a number of formats)

a variety of content (such as text, graphics, video, documents etc), whilst being constrained by

a centralized set of rules, process and workflows that ensure coherent, validated content electronic content.

What is a CMS?Helps you create/edit/delete content in a

shared repository (database)Organizes contentContent shared across the Web siteContent can be published or not based on

conditions (Approved, Date range, Viewer rights)

Much improved control of the format (CSS)The system itself is definable as a tool or

combination or tools that facilitate the efficient and effective production of the desired 'output' using the managed content.

What are major components of a CMS?An integrated set of software tools

that support the content management functions

The major components are: Data repository User interfaceWorkflow schemeEditorial tools Output utilities

How does a CMS work ? Basic information flow

1. Template is designed2. Content is entered as plain-text or HTML into

database3. Content is placed in a template for display to

the end user

Benefits of CMSCreation of content in a standard

format using a Web browser and WYSIWYG editor (Frontpage, Dreamweaver -- bye-bye)

Share the work with several staff members and have options to let the public enter content (Library 2.0)

Control of branding elementsArchive and reuse content

Why is this a good thing?Pages can be created or changed

without knowing or using HTMLLarge-scale changes can be made to

the site much easierIncreased functionality, including

blogs and RSS feeds/readersStructured Content = Content re-

use

Integration of blogs/RSS

Many systems supply own blogging software

Many can interoperate with popular blogging software such as moveable type

Many include software for parsing RSS feeds, or syndicating our own content

Challenges of implementing a CMS

Distributed versus centralized authorshipOften, programming knowledge/technical

expertice requiredTraining on the systemMigration is a huge project-as big as a

catalog migration
