Content management systems can be sorted into rough categories. As you've probably figured out, there's more to it than just deciding to use a content management system. You have to figure out what type of content you have and which content management system makes the most sense for you. In some cases, multiple content management systems may be the answer. You may prefer to publish your writing using a weblogging tool and to publish your photos using a photo gallery application. Here's a discussion of some common types of content management systems. Weblogging ToolsIt seems you can't escape the term weblog (or more commonly, blog) these days. A weblog is just a website where new items are published in reverse chronological order. The items can be articles, links, recipes, photos, or anything else. Generally the most recent items are displayed on the front page, the site maintains an archive of earlier material, and in many cases the site allows users to publish comments of their own. You can find weblogs on just about any topic of interest, and increasingly weblogs are integrated into other types of websites. For example, many magazines and newspapers publish weblogs as part of their sites. Companies are using weblogs to communicate directly with their customers. Political campaigns are using them to get their message out. In large part, the reason weblogs have taken off is that the format is easy to work with. You can publish short items as frequently as you like, and users know that when they visit the site they'll always see the latest and greatest information right up front. In this lesson, I'm going to discuss a weblogging package you can install yourself called WordPress as well as a hosted weblog tool called TypePad. Google also offers a hosted solution that's free to use called Blogger, which you can find at http://www.blogger.com. You may want to check that out as well. Community Publishing ApplicationsCommunity publishing applications are similar to weblog tools in that they are usually built around publishing items by date right up front. They differ from weblogging tools in that they are more centered around providing features for all of the site's users, not just the site's author or authors. Generally these applications provide the ability for users to register as members of the site, submit stories, and engage in discussions among themselves. Sites that incorporate this kind of functionality include http://slashdot.org/ and http://digg.com/. Some other popular community publishing applications include the following:
WikisWiki-style systems take the most radical and counterintuitive approach to content management. Most wikis not only allow anyone to view articles but also to edit them. Some wikis require users to register before they can view or edit articles, but the wiki philosophy is that every user is an editor. When most people hear about this concept, they imagine that the result will be anarchy, but as long as there is a critical mass of users who want the wiki to be useful, this type of system is resistant to attempted defacement. Wikis generally keep a history of changes made to every article, so it's easy to go back to an older version of a page if someone deletes things they shouldn't or otherwise submits unwanted changes. The most famous wiki is Wikipedia (http://wikipedia.org), an online encyclopedia written and edited by volunteers. Not only can anyone view the articles in the encyclopedia, but they can also edit them. If you know something about Fargo, North Dakota that's not already in Wikipedia, you can look it up there and add your own information. Attempted vandalism is taken care of by volunteers who keep an eye out for it, and volunteers handle disputes over controversial content as well. The name wiki comes from the name of the original wiki software, which was called WikiWikiWeb, taken from an airport bus route in Honolulu, Hawaii. To read more about the nature of wikis and their history, why not read about them in Wikipedia? The URL is http://en.wikipedia.org/wiki/Wiki. Aside from the fact that everyone can edit the pages in a wiki, the other distinguishing feature of wikis is that they generally provide their own markup language instead of HTML. Generally wiki markup is less flexible than HTML, but also a bit easier to get the hang of. Unfortunately, wiki markup usually differs between wiki software packages, so learning MediaWiki's markup language won't help you out a whole lot if you start using TWiki, for example. Wikis aren't right for every project. If you want to publish your poetry online, putting it up on a page where anyone can edit it probably isn't a good idea. On the other hand, if you need a site where a group can collaboratively write documentation for a project, a wiki can be a great choice. Here's a list of other popular wiki applications and hosts:
You can find a comparison of various wiki software packages at http://en.wikipedia.org/wiki/Comparison_of_wiki_software. There's also a list of hosted wikis that you can use at http://c2.com/cgi/wiki?WikiFarms. Image GalleriesAs digital cameras have grown more popular, so too has sharing photos online. There are many photo-sharing sites online that you can use to host your photos. Some popular choices include Flickr (http://flickr.com/), Kodak EashShare Gallery (http://kodakgallery.com/), Snapfish (http://snapfish.com/), and Fotki (http://fotki.com/). If you just want to upload pictures and share them with your friends and family members, these sites provide an easy way to do that. In some cases, however, you may want to host your own image galleries. A number of popular image gallery applications are available that vary in terms of complexity and the extent to which they can be customized. The good ones take care of creating thumbnails of your images for you so that you can just upload your photos without dealing with image-editing programs yourself. In this lesson, I'm going to discuss Coppermine, a popular image gallery application written in PHP. General-Purpose Content Management SystemsThere are far too many general-purpose content management systems to list here. Some content management systems are really just toolkits that enable you to build something on your own. Others are highly structured with tons of features that you control via configuration, rather than by writing code on your own. Here are some features that these general-purpose content management systems tend to have in common:
