OntoWiki: a Semantic Data Wiki Enabling the Collaborative Creation and (Linked Data) Publication of RDF Knowledge Bases.
Sebastian Tramp, Philipp Frischmuth, Norman Heino · 2010
In our demonstration (with supportive poster) we want to present the Semantic Wiki application OntoWiki, which is an extensible tool for managing structured information in a collaborative, web-based environment. OntoWiki provides sophisticated means for navigating, visualising and author-ing of RDF-based Knowledge Bases. It serves and consumes Linked Data and comprises a comprehensive middleware API for building custom Semantic Web applications. We refer to it as a Wiki, since our focus is on simplicity, adaptability and collaboration. However, other than anno-tating text-based Wiki pages with a special syntax (as sug-gested by text-based Semantic Wiki approaches), OntoWiki uses RDF in the first place to represent information. For human users, OntoWiki allows to create different views on data, such as tabular representations or maps. For machine consumption it supports various RDF serialisations as well as RDFa, Linked Data and SPARQL interfaces. Since its introduction [1], the application has evolved into a frame-work for building Semantic Web applications [2] and was recently updated to support the collaboration across multi-ple domains and application via Semantic Pingback [3] and RDFauthor [5]. 1. DEMONSTRATION CONTENT OntoWiki can be used to author, manage and publish RDF-based knowledge bases. In particular, our demonstra-tion will focus on the following topics1. We have highlighted several phrases and keywords to give the reader a better overview on the main demonstration points. Navigation and Visualisation OntoWiki provides a number of ways for navigating through RDF knowledge bases. These include taxonomy and hi-erarchy browsing (e.g. via SKOS taxonomies or the class hierarchy), facet-based browsing (with complex filter conditions and attribute based tag clouds) and full-1The feature list is far away from being complete, so please refer
