Forum:What is this function?

So I've come accross a few fuctions that I can get my head around them and I can't find them by googling.

Title:: and

and Gender::

What does the double colon in general mean?

thanks in advance

 * Those are used in templates. For example, if [[File:]] is included in a template, then it means that you can insert to insert a picture &mdash;  S a m   Wang  09:50, April 20, 2012 (UTC)


 * No no I mean the double colon part. Sorry if it was vague but I asked at the end. and do you know what tags, they mean "reference" &mdash;  S a m  Wang  11:30, April 20, 2012 (UTC)


 * Yea, what confuses me is that I know we have [[File:filename]] for images but I don't know where Title:: or Gender:: came from which is weird.Dem0n Hunter 12:40, April 20, 2012 (UTC)

Double colons are often used with various features of the Semantic MediaWiki extension. If you give a link to where you've seen them, I could tell you if it's indeed SMW that utilizes them there. — Sovq 14:33, April 20, 2012 (UTC)

That looks like code for a semantic template design. In SMW-wikis, Gender:: means that, for a specific page that uses our template, the Attribute:Gender is set with whatever is given with the "sex" parameter of the template call.
