AnnotateText is a Django App that lets you select parts of a text of some model and write an annotation for it. Nothing too special. Two cool things, though:
- If the original text changes, the selections of this text will try to smartly adapt to the change. And by 'smartly', I mean I use the SequenceMatcher of the difflib module.
An example of this App in the wild can be found (in German) on bundestagger.de: http://www.bundestagger.de/16/sitzung/1/#annotation-1
