A template based approach is an approach which rely on a template or a fixed structure to do something.
Template based information could be information derived from a template.
What could be the opposite of template-based?
- Non template based
- Template free
Update: Some asked me about the context, it's in the field of computer science and web data extraction tools (web scraping , web wrappers).
A web data extractor can rely on the template of a website in a template-based approach. The opposite could be non-template based approach.
But for the second sentence above (template based information), I doubt the opposite to be "non-template based information"! maybe template independent or template free information?! or maybe just a description is required. Or maybe such combination is odd!
