Controlled Access over Documents for Concepts Having Multiple Parents in a Digital Library Ontology
AbstractThis paper proposes a solution to a problem present in Digital Library ontology for accessing concepts having multiple parents. Instead of considering the underlying structure as a tree, authors consider a DAG structure for concept nodes having multiple parents. A hashing mechanism has been developed to avoid change in document annotations against change in ontological structure. The paper highlights the problem and describes the methodologies avoiding the algorithmic details for paucity of space.KeywordsGeographic Information SystemAccess ControlDigital LibraryAccess Control PolicyAccess Control ModelThese keywords were added by machine and not by the authors.
