Sivan wants to develop an QML app that uses REST web services. He knows that Qt has a great set of examples to show many of the capabilities of the framework and is sure he will find such an example. He uses the Qt Creator IDE as a one stop shop for all of his Qt (and even C++) needs. He open the IDE, goes to the "Welcome" screen, ticks the "show examples and demos" checkbox and gets a list showing all the demos and examples that are shipped with the SDK. He uses the search bar and enters "REST". He gets a list of all the examples and demos that are using REST web services. He does not use a "special" tag list, nor does he need to know he needs to use a tag list to find demos and examples. meta data tags are automatically searched by if he enters them into the search box and they truly reflect the content.
For example, if right now I open the IDE and enter this into the searchbox:
tag:"qml" I get just the 2 intro tutorials and not the many examples with QML.
if I put tag:"qtquick" I get nothing.
