A Publishing Style Web CMS
The Alfresco Web Content Management is a next generation tool that allows
organizations to rapidly create and more effectively maintain dynamic Internet,
intranet, and extranet sites, enabling a shortened web development cycle, providing
high returns on investment, and low cost of ownership. WCM manages the content
and structure of websites, including the framework and navigation, as well as the
creation, editing, approval, and publication processes. By using Alfresco you can
implement web content management solutions with a scalable content repository:
Web 2.0 AJAX-based user interface, exible workow, multi-language support, and
a robust search engine.
This chapter provides an introduction to Alfresco WCM, outlining the benets
of using it for your enterprise's web content management requirements. It also
introduces the new features of the Alfresco WCM.
In this chapter, you will learn about:
• Alfresco WCM architecture
• The Alfresco WCM model
• Features of Alfresco WCM
• Benets
Good web content management pays big
dividends
When an organization's management team is reviewing budgetary proposals, the
price tag associated with a new computing solution often elicits one question: "Can't
we avoid this expense?" The answer is obvious: you can continue to operate your

websites without the benet of a content management solution. However, the real
question should be, "What is the cost of not making this purchase?"

Here are some factors to consider:
High labor costs and the shortage of qualied
personnel
Finding and holding on to qualied employees can be a challenge. All the more a
reason to make the most of each individual's skill set. A web content management
solution that empowers content providers to post directly to a live site increases their
productivity. By the same token, IT personnel who are not ensnared in the posting
process are free to apply their skills and knowledge to more challenging tasks.
Providing state-of-the-art tools helps promote positive attitudes while improving
productivity, which can go a long way in retaining skilled personnel.
How long it currently takes to implement site
changes
Does it take hours or even days to post new content on your websites? That's often
far too long to leave outdated or incorrect information on a site. After all, the beauty
of the Internet is providing target audiences with 24x7 access to all of the latest
and greatest information. When a site becomes stale, users become disenchanted
and are less likely to return. Recapturing a user's interest is far more difcult than
maintaining it with fresh, personalized content.
Potential problems caused by erroneous or
out-of-date postings
When new information doesn't get posted quickly, what does it cost your
organization? In case of a publicly-traded company, incorrect nancial postings can
have serious consequences. Providing only accurate, timely product information can
prevent misunderstandings that lead to customer dissatisfaction. Giving distributors
and suppliers incorrect, out-of-date, or partial information can have a negative effect

on your bottom line. The right web content management solution, one that is easy to
use and maintain, will help ensure that your organization provides site visitors with
reliable content.

Revenue losses attributable to an inability to
respond
A website that cannot be scaled to meet a business' emerging needs is just as
serious a problem as an inability to hire more people, move to a larger facility, or
acquire additional suppliers. Revenue can be lost and the future of the organization
diminished. Why take such chances, especially when websites are becoming central
to doing business?
Competitive issues related to a lack of
planning
Hiring an experienced webmaster allows an organization to use that individual's
skills beyond day-to-day site maintenance. A knowledgeable individual can help
review site architecture, assess future site requirements, and implement upgrades.
These are valuable activities for growing organizations that want to remain
competitive in today's rapidly changing economic environment. However, when
the webmaster must operate as a "web page processor", the time and skills of this
valuable resource cannot be fully utilized.
The right web content management solution can allow your organization to:
• Make effective use of all internal resources
• Slash the time required to implement site content changes or redesign a site
• Ensure the availability of timely, accurate information
• Scale its website to keep pace with organizational growth
• Plan to accommodate new business initiatives and technological advances
Various WCM systems in the market
The worldwide Web Content Management market has been growing exponentially.

The market maturity has homogenized much of the competition. Therefore,
procurement decisions should be increasingly based upon vendor viability and the
vendor's long-term product strategy. Maintaining your web assets is both a cost of
doing business and a competitive differentiator. There are proprietary and open
source WCMs available today for organizations to choose from. Alfresco is one of the
leading choices when organizations look at the open source options available
to them.

The Alfresco WCM engages customers through next-generation sites, enabling mass
contributions from internal and external users, simple conguration via reusable
web scripts, and low-cost massive scalability that uses commodity software and
hardware.
Cutting edge technology, rich interface experiences, user participation, and effective
costing are all factors that organizations seek to consider while selecting the best
suited WCM solution for their organization.
From a high-level perspective, WCM solutions in the market today can be classied
into two types:
• Wiki style
• Publishing style
The following table shows the differences between the two types:
Features Wiki Style Web CMS Publishing Style Web CMS

The Alfresco WCM model
Content Production and Content Delivery are separated in Alfresco Web Content
Management, as shown in the following diagram:
It is important to understand the concepts that form the basis of the Alfresco
WCM model.
Web projects
Web projects are the production-side representation of a site. This is what manages
the content consumed by the site. Here the access rules and roles for content
producers are dened. Every Alfresco server can have multiple web projects. Within
a web project the user can:
• View content based on the state of their User and/or Staging Sandboxes
• Preview content based on the state of a sandbox with workows
• Upload le-based content
• Create web forms and manage content
• Submit content to staging and deploy content to a live environment
These actions can be controlled and managed through the use of workows.
Sandboxes
Alfresco provides a sandboxed development model. Content producers make use of
the sandboxes to make changes to a site in isolation from one another. The default
conguration is as follows:
• One Staging Sandbox per web project
• One User Sandbox per user per web project
