Hey guys, I am writing a document for a university project which asks me to cover RDFa, data aggregation and the semantic web. After a week of research I am not sure I understand all this. Is it normal for sites to aggregate data from third party sites? Is this legal? How exactly would this be done?
I have read all of the Wikipedia sites and plenty other documentation, but I am interested in you guys opinions, on how it should be done and why. How do you draw in information from others sites which is directly relative to the content you already have?
I would appreciate any information on this at all!
