This short booklet is a guide on how to start a wiki website and run it, including the choice of wiki software, whether to host the wiki yourself or go for a hosted wiki, and what choices there are of hosted wikis.

Overview

Before deciding to start your own wiki, if you plan to write about something that may be of general public interest, there is a good possibility that there is already something similar online. Remember, a bigger wiki (with more participants) is often more fun. If, or rather when, you get hit by spammers and vandals, having a big community and others willing to help out can be invaluable. Perform extensive research using search engines to make sure that a suitable wiki does not already exist. A Google search for 'wiki' currently returns about 436,000,000 results; duplicating efforts is very unhelpful - it only means some helpless soul will end up confusing the two wikis at some point in the future.

Some good places to find out if a wiki already exists include:

Technical challenge and community challenge

Despite the first impression, the biggest challenge for a wiki is not technical but human. There is lots of tools and documentations for the wikis. The main issue is to start the wiki, verify that anything is working and see nobody coming or staying without knowing why. That's the reason why the book deals more with relational points than technical points.

Before starting

One key aspect to make a successful wiki is to create it for good reasons. Do you want to create it because one day you realize that this wiki does not exist, because you have needed this wiki or because you want to have your own wiki and you have found an idea to do it? In the last case, your wiki is likely not to grow, because the project is focused on you, not on the community. If your wiki has been created to highlight yourself, nobody will want to contribute.

The contributors should feel that they are highlighted by contributing. You should search people that are interested by your project before you create the wiki instance. If you do that, they will feel that this project is also their project. If you first create the wiki instance and then you search people, they will never feel that it is their project but yours.

Your concept should fit to the wiki mechanism. The pages of the wiki should be atomic, that is to say, one page does not need other pages to be comprehensive. Otherwise, your wiki will be hard to edit. That means that a reader needs to read several pages to get the benefit of one page and a contributor needs to be aware of the other pages to do a small edit. If it is an encyclopedic content like Wikipedia, there is no problem. The more atomic the content is, the quicker the wiki will grow.

The content should self-explain why it is done that way. For example, if you are the only website in the world to display a content in a given form, the first reader will remove the content.

Hosting - self or external

If you still want to run your own wiki, you will either need to run your own web server or have someone else manage a server for you.

"from scratch": you install whatever wiki engine you choose. You control everything. (Either on your own hardware, or on any suitable web host).
"hosted wiki": most technical decisions and support issues are handled by someone else, and you handle the social aspects of growing the wiki.

If you already have a web server, but your web host does not specifically say they host Wikis (for free or a fee) just see if they support the scripting language that the Wiki software you want to run requires. Many wikis require just PHP, Perl, or some other common server-side scripting language that most web hosts provide. Other wikis require a database (e.g. MySQL database) and/or have other requirements.

Self-hosting

For more power and flexibility or for business applications, many people will want to serve their own wikis. This requires considerably more knowledge about how wikis work and especially about wiki software.

Business Environments

Especially in business environments, administrators may be interested in wiki security. Many people believe that nobody who is granted read access should be denied write access or wikis lose their power, but there are times when administrators will want to restrict which users are allowed to access a wiki.

Another consideration in business environments and other large organizations is whether or not the wiki software can interface with other logins. E.g. Twiki can get the username from Windows NT, allowing users username level access without a login. Such schemes allow the benefits of usernames without discouraging users from participating by making them log in.

Businesses may choose to outsource the hosting of the wiki environment. For intranet installations, companies such as SocialText offer a hardware-based "appliance" solution. For customization, design or production of wiki projects, companies such as CiviHosting and Wiki Studios offer professional wiki services to business, non-profit organizations and branches of government.

Customizing software

One of the benefits of hosting a wiki oneself is the ability to recode the wiki software. For an example of this, see Sensei's Library. The administrators of Sensei's added Go markup functionality to their software for easy illustration of Go boards and pieces.

Choosing the wiki software

There are more than one hundred wiki engines available. Some good starting points are to read Comparison of wiki software, Top Ten Wiki engines, WikiMatrix comparison table. To decide what kinds of software you would want, list all the criteria that are important for you. Then sort the ones that are required and the ones that would be great to have. Start filtering all the wiki engines that don't feature your required criteria and sort the remaining wiki engines with the great criteria. The most important points could be:

Which server can I use for it?
-> On which server and hardware can it run?
Am I ready to spend money on it and how much?
-> Should it be free?
Am I ready to use a tool entirely written in English only?
-> Should it be i18n?
Will the contributors be able to write in wikicode?
-> Should it be WYSIWYG?
Can I do all I want with only simple text?
-> Should it feature extensions and advanced features?
Will the contributors import content from other wikis?
-> Should it have compatible format with other wiki or wiki engines?
Is my project critical?
-> Is it actively updated? Is there a large community of developers?
Is my project very advanced?
-> Can it be recoded? Open source?
Should my project be attractive (commercial needs for example)?
-> Is the display customizable?

Hosted Wikis

There are companies that host wikis for free or for a price. This means that you do not have to deal with complex programs like Ruby, PHP, MySQL, or Apache. The wiki host will do this for you.

Beware! Some hosts delete wikis without notice. Make sure you are saving your own backup copy of the data in your wiki. Some hosts make it easy to download everything you would need to run your wiki somewhere else, by using an open source wiki engine and providing backup dumps with full edit histories. Other hosts lock you in more, e.g., with proprietary wiki markup languages, proprietary wiki engines, or limited backups.

Free wiki hosting

You can also find a comparison of wiki farms on Wikipedia and a list of hosting services on MediaWiki.org.

You won't get a subdomain for your wiki (for example, if the name of the wiki you create was Example, the url of it would be editthis.info/example/). The only available skin for your new wiki would be Monobook. You don't need to be a registered user to add a wiki and you can create as many wikis as you want.

Choosing a License

Before you start a wiki, it is essential to choose a suitable license. Once users start contributing to a wiki in which the license is not clearly specified, you may run into a licensing nightmare, having to track the authors of content without proper license.

The licenses proper to a wiki include:

FDL. GNU Free Documentation License, used by Mediawiki projects. Beware that this license is incompatible with GNU General Public License. Choosing a GNU GPL for a wiki is unfortunate, as it has been designed for software, not for texts in human language.
Creative Commons. One of the Creative Commons licenses
Combination of the two
PD. Public domain license, the least restrictive license.

According to some interpretations of the law, it may be illegal to ever change the copyright license of a wiki without getting explicit, written consent from everyone who has ever posted on the wiki, unless the copyright license itself has explicit provisions for changing the license.

The public domain license is the only license that lets you change the license later. If you or your users later decide they want some license other than public domain, you might want to check out the license comparisons in Further reading.
