For retrieving the Twitter stream we connect with the Streaming API to the endpoint of Twitter and receive a never ending tweet stream. As Twitter delivers the tweets as [http://www.json.org/ JSON] objects the objects has to be
converted into XML fragments. For this purpose the parse function of the [[JSON Module|XQuery JSON Module]] is used. In the examples section both versions are shown ([[#Example Tweet (JSON)|tweet as JSON]] and [[#Example Tweet (XML)|tweet as XML]]). For storing the tweets including the meta-data, we use the standard ''insert'' function of [[Updates|XQuery Update]].
