ABSTRACTThe ongoing growth in research data publication supports global intra-disciplinary and inter-disciplinary research collaboration but the current generation of archive-centric research data repositories do not address some of the key practical obstacles to research data sharing and re-use, specifically: discovering relevant data on a global scale is timeconsuming; sharing 'live' and streaming data is non-trivial; managing secure access to sensitive data is overly complicated; and, researchers are not guaranteed attribution for re-use of their own research data. These issues are keenly felt in an international network like the Worldwide Universities Network (WUN) as it seeks to address major global challenges. In this paper we outline the WUN Web Observatory project's plan to overcome these obstacles and, given that these obstacles are not unique to WUN, we also propose an ambitious, longer-term route to their solution at Web-scale by applying lessons from the Web itself.

Abstract:The orchestration of the Web is a big issue for Web users all around the world. Web users have a high interest in services, which are able to personalise and customise the Web. However, for Web reactivity there exists only a few limited solutions that allow the aggregation of Web resources. This paper takes a look at existing eventbased methods that build upon Event-Condition-Action (ECA) Rules and Complex Event Processing (CEP). Moreover, this paper illustrates the architecture of a fully functioning Condition Action System prototype for the creation of reactivity in between Web resources. In a proof of concept, we could detect and determine the change interval of electronic newspaper headlines. With the proposed system, we are able to orchestrate Web resources e.g. Detecting Web Changes.
