“How XML Threatens Big Data”

Minimal markup seen from a data point of view rather than a document point of view.

I wouldn’t say it is XML’s fault as such, but it being used for a purpose it is less than ideally suited for, a consequence of early oversell (those who remember 2000 would know what I talk about).

There is another lesson that is web-relevant. Big dataset like these shouldn’t be naively be tagged into an XML format and presented as is on the Web. This is because in a web setting the overhead for each element is rather large as the DOM will be applied to it, allowing arbitrary dynamic mutations. It is easy to overwhelm even the most powerful processor this way and zap all available memory.
