Framework supporting rapid information modelling

In this paper, we present a framework capable of supporting Rapid Information Modelling. The management of information is done at the conceptual level without the user having to define a data model for information organisation. We introduce the notion of heterogeneous collections together with a flexible notion of typing. One can easily define new typing constraints according to user needs and integrate them into the framework. To support the processing and querying of information, we provide algebra operations which can be evaluated with or without type checking. An initial version of the framework has been implemented as a web application offering flexible access to information.
