There's another workgroup a-brewin' down on the wiki! This one is
about categories; yes, dreadful fun, I know. Before I talk about the
workgroup, I'd like to introduce you to the concept, and the rationale
behind their use.
What are categories?
A category is just what it sounds like: a method of grouping pages
according to their content. Categories also work with parent-child
connections in the same way that subpages do. The category you put a
page in will actually be a subcategory of another. A category system
will have many levels within it. Where the category system gets even
more useful than the subpage system is in the number of relationships
that can be defined by it. While a subpage can only have one parent
page, any page or category can be in as many categories as we like.
This is where the mediawiki software becomes genius in its use of
virtual reality; even though there exists only one document, at a
single url, it can be found and related to other documents in any
number of ways. This creates a powerful browseability that is trumped
only by the searchability of the SemanticWiki extension, which involves
a steep learning curve.
Why categories?
The category system is a built-in method of organising content far
better than the subpage system method. It creates relationships
between
content that cannot be defined by subpages, making it easier for
members to move from page to page and between related information.
Want to know what other projects there are on astrophysics? The
category system will tell you that. Want to be able to find all the
resources from Otago Poly-Tech easily? Curious about what 10 year old
children are learning elsewhere in the world? The category system
allows for these. Using the category system is preferred over contents
pages because it requires far less effort from members to keep
current. To add a page to a category, one never has to leave the
page, itself!
The other key factor for categorising pages is a concept called "search
engine optimisation" (SEO). You may have heard of this if you are in
any way involved with web publishing. I'm not going to explain SEO,
but I will tell you the point of it is to increase readership
organically (they come to us, we don't market directly to them). This
is done by appealing to the formulas Google and other search engines
use to determine who goes at the top of any search list. The thing is,
if there aren't any links to your page, Google never sees it!
Categories create a link-based map of the website, allowing Google's
programs to see each page that has a category.
The workgroup
Sounds great, right? Well, WE's category structure is a bit out of
shape at the moment. For example, about 30% of the categories used
don't actually exist, yet; there are a handful of central/root/contents
categories, none of which go deeper than a few levels; there are (as I
write this) 12,200 uncategorised pages out of 68,992 total, or about
15%; and most of the existing categories aren't connected to any other
category.
So, Alison Snieckus and I have seeded a workgroup to get WE's category
system in tip-top shape, as well as working to educate WE members on
categories and advise the style guidelines workgroup on guidelines that
affect category usage. We're still organising the group, and there are
some tasks to be done, and we could use your help with both! WE would
really benefit from your opinions and ideas, so please stop by (
http://www.wikieducator.org/Workgroup:Categories
) and sign up. There are lots of informational links, and it isn't
necessary you be an expert on wikis or the category system to take
part, but you might find you know a lot more when we're all done. If
you have any questions, please feel free to ask here, or on the
workgroup talk pages. As with the style guide workgroup, membership
isn't required to participate in discussions, it just helps us to know
who wants to be involved so we can give them credit and to make sure
everyone has something to do to help.
