If XML is to get anywhere near as popular as HTML is today, it needs to address a pretty basic requirement: the ability to connect different pieces of data together. Luckily, the W3C has a solution...and it's called XLink. Read on for the scoop.
While the promise of XLink is tremedously exciting, there are as yet very few implementations of the technology, and so it's hard to truly grasp many of the applications that it makes possible. However, as the technology matures, expect to see XLinks gradually taking over from standard anchor tags, and data being linked in new and interesting ways.
Until that happens, though - stay healthy, and I'll see you soon!
