3 -= What is a wiki? =
4 -
5 -A wiki is classically presented as a set of web pages editable by all users with permissions. It allows the collaborative creation of content (including text, images, videos, etc.), as well as the creation of links between different sets of content.
6 -
7 -Wikis were made popular by the famous multilingual Wikipedia encyclopedia (created in 2001) that became one of the most visited websites in the world, with more than 17 million articles (beginning of 2011).
8 -
9 -Basic wiki features are:
10 -
11 -* Page creation
12 -* Page modification: it simply consists in the addition/modification or suppression of content
13 -* Creation of links between pages
14 -* Ability to aggregate all the knowledge of the contributors to the wiki into nice readable pages instead of having the knowledge scattered into various threads of discussions as you get with mail or chat tools
15 -* History: it is possible to follow the modifications made on a wiki page (What was modified? By whom? When?)
16 -* Rollback: it is always possible and easy to rollback and choose the previous version of the wiki page.
17 -
18 -But some wikis, such as XWiki, go much further by proposing additional features addressing professional needs.
19 -
20 -= Two of the best known professional wikis: Confluence and XWiki =
21 -
22 -== Confluence ==
23 -
24 -Confluence is a team collaboration software. Written in Java and mainly used in corporate environments, it is developed and marketed by Atlassian, the Australian company best known for Jira, its issue tracking application. Confluence is sold as either on-premises software or as a hosted solution.
25 -
26 -Confluence is a business-oriented professional wiki with advanced features. Compatible with many databases, Confluence is a proprietary software, but it also offers free licenses for some open source projects and reduced pricing for educational and non-profit organizations.
27 -
28 -Confluence is used by many companies around the world: Facebook, NASA, eBay, Adobe, etc.
29 -In terms of business usage, Confluence is used by one or more teams to share, find and interact with information. Confluence is mainly used as an enterprise collaborative tool.
30 -
31 -== XWiki ==
32 -
33 -XWiki is an open source project supported and developed by the [[XWiki community>>]] and by [[XWiki SAS>>]]. It is developed in Java and distinguishes itself from the other wikis by offering **enterprise-oriented features** such as:
34 -
35 -* Office documents import (i.e. a Word document is transformed into a wiki page; XWiki retains the layout, images contained in the document and also the documents attached to the page)
36 -* The management of unstructured data (like Wikipedia), as well as structured data (forms, spreadsheets)
37 -* Data export in many formats (PDF, HTML, XAR)
38 -* An activity stream displaying an overview of all the wiki activities
39 -* Very strong customization abilities: logo, colors, look and feel, skin, menu contents, and even UI and behavior of applications (through scripting in pages)
40 -* Connection to Enterprise Directories (data retrieval, LDAP, Kerberos, SSO)
41 -* Fine-grained rights management (by wiki, space, page, and even programmatic in wiki pages)
42 -
43 -Other strengths include **flexibility and scalability**. XWiki allows the creation of dedicated/specific applications (Meeting management application, Customer Relationship Management...).
44 -
45 -Lots of extensions, applications and macros are available on the [[Extensions web site>>extensions:Main.WebHome]]. These come on top of the default features that are provided in the [[default distribution>>enterprise:Main.Features]].
46 -
47 -Moreover, XWiki is an Open Source software developed under the LGPL license. So you own your wiki and its data. Note that XWiki SAS, the company who's sponsored most of the development of XWiki, has published an [[Open Source Manifesto>>]].
48 -
49 -In terms of business uses, XWiki is used by teams to create knowledge bases and collaborative workspaces but also across the company as an intranet, extranet, website, etc..
50 -
51 -XWiki counts amongst its clients big companies, such as: EDF, DCNS, EMC, EADS but also SMEs and associations.

132 -**In terms of features and technologies, XWiki and Confluence look very similar in appearance.** Both are developed in Java and include many features by default. Extensions and plugins are available and they can extend other functionalities.
133 -
134 -**The major difference lies mainly in the capacity of customization and developments around the software. **While Confluence is a proprietary software that is rather rigid (i.e. standard solution for all clients / to take as is) and can be hosted by Atlassian or by itself, XWiki is a completely open development platform that can be easily adapted to any specific business need.
135 -
136 -NOTE: Confluence has been criticized for dropping markup in favor of HTML only (forcing users to use Confluence's WYSIWYG editor). It is no longer possible to edit, copy or see the wiki syntax because the content is no longer stored in the "wiki format ([[source>>url:'sChangedforWikiMarkupUsers-Functionalitythatisnolongeravailable||rel="__blank"]]). On the other hand XWiki has made the choice to fully support several [[markup syntaxes>>rendering:Main.WebHome||anchor="HSupportedSyntaxes"]] in addition to offering a powerful WYSIWYG editor.
137 -
138 -== In terms of market positioning ==
139 -
140 -**XWiki and Confluence have opposite business models.** Confluence is a proprietary software. The purchase of licenses depends on the number of users. XWiki, on the contrary, is an Open Source software. You can freely use it and modify the code to customize the tool.
141 -
142 -**XWiki is aimed towards businesses**, work groups and developers that use it for their users, while **Confluence is aimed directly toward teams and developers.**
143 -
144 -= Why use XWiki rather than Confluence? =
145 -
146 -**An open model**
147 -
148 -**XWiki is a 100% Open Source software** (developed under the LGPL license), unlike **Confluence, a proprietary software**.
149 -
150 -This brings a number of **benefits**.
151 -
152 -* **From the innovation point of view. **At XWiki, we believe that innovation is led by transparency and free competition. With Open Source, the contributors are protected and they know that their investment will be maximized because it can be taken freely by other contributors who will improve it and give back to the community. Everyone enjoys contributions from others.
153 -* **Better adapted to the market needs. **Open Source software is developed openly. The contributors provide ideas, raise bugs, send fixes or suggest new features. The Open Source community helps the software developers to better meet the market needs. If the main developers are reluctant to develop some features, the community can develop them.
154 -In addition, Open Source software is often more open (through APIs), more standard-compliant and also easier to update.
155 -* **No limit to adaptations. **Beyond the traditional extension capabilities (plugins, look and style adaptations) that proprietary software also supports, for Open Source there is no adaptability limit: it is always possible to access the source code and make a new version of the software.
156 -Even if proprietary software could be designed to allow some adaptations, there will still be cases where, without modifying the software code, some changes will not be possible. This will never be the case with open source software.
157 -* **Lock-in reduction and reversibility in the Cloud. **This is a very important point for users. Even if proprietary publishers can offer reversibility for cloud services, this reversibility is rarely checked. With the Open Source software, you can test this reversibility yourself.
158 -With Open Source, there is no lock-in, that means that you can always change your hosting provider and support if you are not satisfied. You can still update the software. With proprietary software, you will have to abandon it.
159 -
160 -* **Updates under control. **As the software is Open Source and often updated (instead of the usual 3-year cycles for proprietary software), improvements are added gradually (at least this is the case for XWiki) with a commitment on strong backward compatibility. Users can control the updates. Even if the publisher decides to limit the backward compatibility to some versions, users can freely choose to do the complex (or not complex) update, since they can turn to a developer who wants to continue to support the old version.
161 -The ability to update is a key point for business software, especially when you add personal customization to the software. Often with proprietary software, updates are complicated because the software is heavily modified at each major release to "enhance" the new version license sales.
162 -
163 -**A tool that can be used across your business**
164 -
165 -**Unlike Confluence, XWiki is extensible**. Specifically, it allows you to start using XWiki for a department's special needs within your company and see how it works. If the project "takes off" and the other departments want to use it, then XWiki can "evolve" and become a true corporate Intranet.
166 -
167 -**XWiki is the Open Source leader while Confluence is the proprietary software leader.**
