1 Introduction to Oracle WebCenter Wiki and Blog Server

This chapter introduces concepts related to wikis and blogs and provides an overview of Oracle WebCenter Wiki and Blog Server 10g Release 3 (

The chapter includes the following sections:

1.1 What You Should Know About Wikis and Blogs

1.1.1 About Wikis

A wiki is a type of web site where users can browse available content and update, remove, and otherwise edit the content, sometimes without the need for registration. This ease of interaction and the variety of operations makes wiki an effective tool for collaborative authoring, where multiple people create written content together using HTML or a simple wiki mark-up language.

Wikipedia is an excellent example of a wiki ( ). Users from all over the world collaborate to create and edit Wikipedia pages, resulting in a rich, dynamic knowledge base for everyone's benefit. For more information about wiki, see the Wikipedia at .

Wikis epitomize the concepts of community and collaboration by allowing all authorized community members to contribute their information to the greater body of knowledge. Adding these new collaborative ways of authoring information does not require a full content management system. Here are a few scenarios where wikis can be used:

  • In a globally dispersed team; team members can update a single proposal without having to track e-mail attachments and merge all comments into one document.

  • In a large team; everyone knows where to go to get the "single point of truth" for current plans or status information using a wiki.

  • In taking anonymous input; people can comment on the wiki but not edit it directly, thereby considering all viewpoints.

1.1.2 About Blogs

Blogs, on the other hand, are more personal records of an individual user's experience and opinions. The word blog is a contraction of the term Web log. It was coined to describe the online diaries spawned in the late 1990's.

Blogs provide a useful tool for projecting, discussing, and/or evangelizing any type of idea, strategy, or point of view. The audience can be a select group of people or a projection out to a wider audience. Typically, blogs invite readers to comment on the overall concepts. Blogs also allow the author to determine whether others should see these comments or whether they incorporate the comments into the base blog.

Some typical scenarios where blogs can be used include:

  • CEOs of companies telling their investors and customers about ideas they have for the future direction of the company

  • Architects of technology companies providing new directions or approaches to solving complex problems

  • Sales leaders providing their teams with key selling strategies

  • Business professionals educating colleagues on new opportunities

  • Industry analysts providing viewpoints on point technologies within their area of ownership

  • Service companies providing new and interesting ways to leverage their products and services

1.1.3 Considerations When Using Wikis and Blogs

You can integrate wikis and blogs into your applications. When integrating wikis and blogs into your applications, you must keep in mind certain considerations:

  • Blogs do not really require users to provide their identity when they post comments. You may encounter the problem of unsolicited advertisements posted on your blogs. Many advertising services may automatically add a comment to a blog entry; the comment is nothing more than an advertisement for their product or service.

  • To inform non-team members of project progress, blogs need to be tied into projects that others are working on. So, blogs require integration with the core portal security infrastructure.

  • Both wikis and blogs need to be able to adapt their look and feel to match the application, portal, or web site in which they are integrated.

1.2 What You Should Know About Oracle WebCenter Wiki and Blog Server

1.2.1 About Oracle WebCenter Wiki and Blog Server

Oracle WebCenter Wiki and Blog Server enables you to integrate wikis and blogs into Oracle WebCenter, Oracle WebLogic Portal, and Oracle WebCenter Interaction applications. Oracle WebCenter Wiki and Blog Server also includes features that enable application users to create their own wikis and blogs.

Table 1-1 shows the supported technologies available for releases that include Oracle WebCenter Wiki and Blog Server.

Oracle WebCenter Wiki and Blog Server contains a wiki and blog server that can be deployed on Oracle WebLogic Server 10.3 and configured for single sign-on (SSO) with Oracle Access Manager 10 g. This release does not support the following SSO servers supported in previous releases: Oracle SSO and JSSO. The release also deprecates the sample portlets included with previous releases (10.1.3.x).

Hence, Oracle WebCenter Wiki and Blog Server is focused on customers who are installing Oracle WebCenter Wiki and Blog Server for the first time or who are upgrading from an Oracle Access Manager-based authentication setup. Current customers who use Oracle SSO or JSSO should migrate to this release if, and only if, they are ready to migrate to Oracle WebLogic Server 10.3 with Oracle Access Manager for SSO and they do not need out-of-the-box portlets.

Oracle WebCenter Wiki and Blog Server categorizes its content into domains and pages. Figure 1-1 shows the start page of a domain named owc_wiki. Administrators can create domains, whereas authorized users can create wiki pages and blog entries within a domain. The wiki and blog server tracks every version of a page, including its authors and creation and revision dates. Administrators can configure the wiki and blog server for better administration and management. For example, administrator can create domain-specific menus, create users and assign them roles, and monitor server statistics.

1.2.2 About Integrating Wikis and Blogs

Oracle WebCenter Wiki and Blog Server includes its own web-based interface and Web Services. Application users can use the web-based interface to create and edit wiki pages. Application developers can expose the wiki and blog functionality into their existing portal, application, or web site by using various methods, including Web Services. The best one to pick depends on the type of integration desired or that is required.

The following are the methods for integrating wikis and blogs in your applications or portals:

  • Through the Web Clipping portlet or any portlet capable of consuming a URL

  • Through an iFrame, which you include in a page in your application

  • Through the use of a custom-built user interface that you can create using the provided Web Services
