摘要:
Electronic system architecture for electronic document annotation by hypermedia processable and active annotations, comprising a data processing system, (4,5,6,7,8,9) having at least a user terminal (1,2,3) an operating system (16) for information managing according to a plurality of structural models, navigation means (13,14,15) for navigation from anchors in an information structure, documents in particular, editing means (11,12) activated from terminal for getting access to the documents through the navigation means (13,14,15) and annotation means (17,18,19,20) coupled to the navigation means (13), to the terminal (1,2,3) and to the operating system (16) for creating and processing annotations comprising contents, treated as a linkable node (23) of the information structure and a set of entities-relations, structured in accordance to an entity-relation model, the set being connected to the node, so that each annotation is retrievable through the navigation means (13,14,15) and is further retrievable and processable by the annotation means (17,18,19) according to relational criteria and, based on events, identified as entities of the annotation structured set, automatically starts processes such as note deletion or notification to an addressee.
