Semantic Desktop with KDE
Nepomuk aims to provide the basis to handle all kinds of metadata on the KDE desktop in a generic fashion. This ranges from simple information such as tags or ratings over metadata extracted from files to metadata that is generated by applications automatically. RDF, the Resource Description Framework, provides the powerful basis to store and query all this data. The goal is to categorize all metadata using clean ontologies to make an automated handling and enrichment of the data possible.
Networked Environment for Personalized, Ontology-based Management of Unified Knowledge
NEPOMUK brings together researchers, industrial software developers, and representative industrial users, to develop a comprehensive solution for extending the personal desktop into a collaboration environment which supports both the personal information management and the sharing and exchange across social and organizational relations.
Tracker is a semantic data storage for desktop and mobile devices. Tracker uses W3C standards for RDF ontologies using Nepomuk with SPARQL to query and update the data.
