In the callback function, you parse the response (web page) and return either dicts with extracted data, Item objects, Request objects, or an iterable of these objects. Those Requests will also contain a callback (maybe the same) and will then be downloaded by Scrapy and then their response handled by the specified callback. In Scrapy, an object is considered an item if it is an instance of either BaseItem or dict. For example, when the output of a spider callback is evaluated, only instances of BaseItem or dict are passed to item pipelines. If you need instances of a custom class to be considered items by Scrapy, you must inherit from either BaseItem or dict.
