Presentation at the Research 2.0 Workshop at EC-TEL 2010. Abstract. In this paper we present an ecosystem for the lightweight exchange of publication metadata based on the principles of Web 2.0. At the heart of this ecosystem, semantically enriched RSS feeds are used for dissemination. These feeds are complemented by services for creation and aggregation, as well as widgets for retrieval and visualization of publication metadata. In two scenarios, we show how these publication feeds can benefit institutions, researchers, and the TEL community. We then present the formats, services, and widgets developed for the bootstrapping of the ecosystem. We conclude with an outline of the integration of publication feeds with the STELLAR Network of Excellence and an outlook on future developments.

10. Outlook
Enhancing the vocabulary of SWRC SWRC 0.8
URIs for all entities in the network (e.g. authors,
institutions, projects) Social Handles Archive
(SOHARC)
Improving services and widgets
Feed Merger more sophisticated conflict
management
Including more fields into the visualization
Error correction Aggregator like the Open Archive
Harvesting and processing of RSS PubSubHubbub
