This paper describes DataConf, a mobile Web mashup application that mixes Linked Data and Web APIs to provide access to different kinds of data. It relies on a widely used JavaScript framework and on a component-based approach to manage different datasources. It only requires static server-side contents and performs all processing on the client side. DataConf aggregates conference metadata. It allows browsing conference publications, publication authors, authors’ organizations, but also authors’ other publications, publications related to the same keywords, conference schedule or resources related to the conference publications. For this, it queries the SPARQL endpoint that serves the conference dataset, as well as other open or custom endpoints and Web APIs that enrich these data. DataConf is deployable for any conference with available metadata on the Web using a configuration file. Other data sources can be used by developing and plugging new components in the DataConf architecture.
