摘要

A method for annotating a Web-based document, WBD; in a WBD browser, comprising: displaying the WBD on the WBD browser; detecting by the WBD browser a position in the WBD for inputting an annotation by a first user; requesting the WBD browser a WBD part corresponding to the position by a WBD browser add-on; generating metadata comprising information related to the WBD part by the WBD browser add-on; inputting the annotation; embedding the annotation in the WBD to form an integrated WBD comprising the annotation by the WBD browser add-on; displaying the integrated WBD with the annotation by the WBD browser; and storing the annotation and the metadata in an annotation database by the WBD browser add-on.
