Most, if not all, of the wiki websites are based on a free open source software program from MediaWiki.org. The program is written in PHP, a popular general-purpose scripting language that is especially suited for web development.
The most outstanding feature of the wiki website is its ability to handle huge amounts of data in an efficient and user-based environment. A wiki allows people to add, modify or delete content in collaboration with other users. Quoting from the Wikipedia article on the Wiki, " [A Wiki] differs from a blog or most other such systems in that the content is created without any defined owner or leader, and wikis have little implicit structure, allowing structure to emerge according to the needs of the users."
Here is a further description of the websites from the Wikipedia article:
A wiki enables communities to write documents collaboratively, using a simple markup language and a web browser. A single page in a wiki website is referred to as a "wiki page", while the entire collection of pages, which are usually well interconnected by hyperlinks, is "the wiki". A wiki is essentially a database for creating, browsing, and searching through information. A wiki allows non-linear, evolving, complex and networked text, argument and interaction.Almost inevitably when I talk about wikis, I get the same question, "Why doesn't the information in a wiki devolve into a pile of garbage?" You may well ask the same question about any complex human organization. Why don't countries and cities collapse of their own weight. I guess the answer is that sometimes they do, but you might note that there are cities that have survived for thousands of years. The reason this is a complex issue is because wikis survive and thrive because of basic human nature. People are more inclined to build than they are to tear down. It is that simple.
A defining characteristic of wiki technology is the ease with which pages can be created and updated. Generally, there is no review before modifications are accepted. Many wikis are open to alteration by the general public without requiring registration of user accounts. Many edits can be made in real-time and appear almost instantly online. This can facilitate abuse of the system. Private wiki servers require user authentication to edit pages, and sometimes even to read them.
The other reasons why wikis work are really very complex. If we focus on genealogy wikis, we see two distinct functions represented. On one hand, we have informational wikis that focus on providing resource material such as the FamilySearch.org Research Wiki. On the other hand, we have wikis that are designed to host family tree information such as WeRelate.org. Both applications seem to be very successful in their functions and ability to absorb mountains of information. Wikis work primarily because they fill a very needed function, that is, gathering huge amounts of information in an efficient way with a much reduced expense.
Wikis are not just left out there to live or die, all successful wikis are tightly moderated either by the developer of the wiki, in the case of FamilySearch.org, or by the wiki community. Most wikis have rules about the kind of content allowed and violations of the content rule are quickly eliminated and in some instances users who violate the rules are excluded from further contact with the wiki.
In actual practice, the wiki format can be so dramatically altered by having a custom designed front-end, that the website is almost unrecognizable as a wiki except for its function. This is the case with the FamilySearch.org Family Tree program.
If you haven't done so, I would invite you to review the above wiki websites and consider participating in one or more of the wiki communities.
