PIM through a 5S perspective

Personal Information Management (PIM) is an interdisciplinary research area [4] involving information science, cognitive science, information retrieval, multimedia systems, human-computer interaction, and artificial intelligence. From a digital library (DL) perspective, it involves a focus on personal DLs. Hence, to clarify thinking about PIM, and to allow the results of work on formal models for DLs to be applied, we present a minimal PIM metamodel, building upon the 5S (Societies, Scenarios, Spaces, Structures, Streams) framework and extending the meta-model for a minimal DL [2], which includes digital objects, metadata objects, collections, catalogs, repositories, and services.
