TWiki Interviewed by Robert Scoble
is a flexible, powerful, and easy to use enterprise wiki,
enterprise collaboration platform, and web application platform. It is a
Structured Wiki, typically
used to run a project development space, a document management system, a
knowledge base, or any other groupware tool, on an intranet, extranet or the
Internet. Users without programming skills can create web applications.
Developers can extend the functionality of TWiki with Plugins.
TWiki fosters information flow within an organization, lets distributed
teams work together seamlessly and productively, and eliminates the
one-webmaster syndrome of outdated intranet content.
TWiki has been downloaded over 700,000 times and is used daily by millions
of people in over 100 countries. Some larger deployments have over one
million pages and over 10,000 users. TWiki is developed by an active opensource
community on twiki.org.
What does it look like?
TWiki looks and feels like a normal Intranet or Internet web site.
However it also has a Edit link at the bottom of every topic
(web page); everybody can change a topic or add content by just
using a browser.
TWiki is hosted and developed here at the TWiki.org web site.

Who is using TWiki?
TWiki is installed on many web sites, mainly behind corporate
firewalls. Many major companies use TWiki because it is very user
friendly compared to some well established commercial groupware
systems like Lotus Notes. Read some

How is TWiki being deployed?
A wiki is a Enterprise 2.0
platform to create share and remix content. TWiki as a structured wiki
goes a step further; it enables users to automate their workflow by
creating custom tailored wiki applications.
Companies are deploying TWiki in different ways, and TWiki is
quite flexible to adapt to different needs. Here is a non- comprehensive
list of how TWiki is being used:
To replace a static intranet. Content is maintained by the
employees, thus eliminating the "one webmaster syndrome" of
outdated and insufficient intranet content.
As a knowledge base and FAQ system. The
tells you more about that.
To design and document software projects.
To track issues (i.e. bugs) and features. TWiki itself is
managed this way; more on that in the
As a document management tool.
To collaborate on common goals, such as the
online encyclopedia for Java developers on java.net,
or the Biowiki for computational biology projects
of UC Berkeley.
As a software archive, i.e. the
TWiki Plugins archive.
As a company internal message board, i.e. for job listings.
What are the Main Features of TWiki?
TWiki is a mature, full featured web based collaboration system:
Any web browser: Edit existing pages or create new
pages by using any web browser. There is no need for ftp or
http put to upload pages.
Edit link: To edit a page, simply click on the Edit
link at the bottom of every page.
Auto links: Web pages are
You do not need to learn HTML commands to link pages.
Text formatting: Simple, powerful and easy to learn
text formatting rules.
Basically you write text like you would write an e-mail.
Webs: Pages are grouped into
(or collections). This allows you to set up separate
Search: Full text search
with/without regular expressions. See a sample
E-mail notification: Get automatically notified when
something has changed in a TWiki web. Subscribe in
Structured content: Use
to classify and categorize unstructured web pages and to
create simple workflow systems.
and download any file as an attachment to a page by
using your browser. This is similar to file attachments
in an e-mail, but it happens on web pages.
Revision control: All changes to pages and attachments
are tracked. Retrieve previous page revisions and differences
thereof. Find out who changed what and when.
Access control: Define groups and impose fine grained
read and write access restrictions based on groups and users.
to dynamically compose your pages. This allows you
for example to dynamically build a table of contents:
include other pages; or show a search result embedded in
TWiki Plugins: Enhance the TWiki functionality with server side
Developers can create Perl Plugins using the
TWiki Plugin API.
Some example Plugins:
Application Wiki: Contributors use the TWiki platform to create web
applications. The TWiki Variables, Plugins and sample applications offer
a rich environment where domain-specific applications can be built
efficiently by contributors with moderate skill sets. Developers can create
new Plugins to enhance the functionality of TWiki even further.
Some example applications:
Templates and skins: A flexible templating system
separates program logic and presentation. Skins overwrite
template headers and footers; page content is unaffected.
Managing pages: Individual pages can be renamed,
moved and deleted through the browser.
Managing users: Web based user registration and
change of password.
