DataConf is a mobile Web mashup application that allows brows- ing conference metadata (publications, authors, authors’ organiza- tions), as well as the conference schedule (tracks, sessions, talks). It uses Linked Data and Web APIs to enrich the conference dataset with resources (authors’ other publications, organizations homep- ages) from different other endpoints. It also performs client-side reasoning to retrieve and recommend publications. Unlike other mashups, DataConf dynamically aggregates data on the client side. Server-side calculations are devoted to the queried data sources, not to the DataConf server itself. DataConf is easily con- figurable and deployable for any conference with available metadata on a SPARQL endpoint. Its component-based architec- ture allows developing new extensions to query extra data sources. We also propose several custom data sources, among which SimpleSchedule that provides a convenient interface for managing conference events and exposes them on a SPARQL endpoint and DataPaper that allows conference participants to enrich their own data.
