Last week DDIS representatives visited the European Data Forum (EDF) in Athens. Apart from many personal and informal interactions with other forum participants the project was presented in two different contexts.

On March 19, Abraham Bernstein gave a overview talk about ViSTA-TV. The talk was filmed by Videolectures.net but has not been posted yet. We will be posting a link to the video as soon as it will be available.

In addition, Abraham Bernstein was interviewed by the Greek Public Television channel. The interview, which was part of a report that also contains with the two main organisers and with Marta Nagy-Rothengass, the Head of Unit Data Value Chain within the EC’s DG CONNECT (which finances ViSTA-TV) , provides a succinct overview of ViSTA-TV and sheds light on some possible uses of the VISTA-TV results. The interview is available both as part of the report and on YouTube.

A new version of Cassandra-Esper was released to Maven Central. Version 0.3 now supports insert, update and delete operations as well as proper initialization. Cassandra-Esper provides an implementation of Esper virtual data windows as a distributed key-value store for background information.

Cassandra integration for Esper released

Patrick Minder — Mon, 08 Jul 2013 12:58:56 +0000

The DDIS group at UZH released the first version of the cassandra-esper library at Maven central. The cassandra-esper library integrates Apache Cassandra via virtual data windows into the Esper complex event processing engine.

The ViSTA-TV engine can now directly query the data warehouse’s key-value store from its complex event processing part. Queries can be directly expressed as part of statements in the Esper Event Processing Language (EPL).

Further, the DDIS group also released the testng4esper library at Maven central. The testng4esper library facilitates writing TestNG tests for programs using the Esper complex event processing engine.

Library streams-esper released on Maven central.

The DDIS group released the streams-esper library on Maven central. The streams-esper library allows to use the Esper complex event processing engine with the Streams platform for stream processing. It enabled the ViSTA-TV engine to query and match complex events on streams of IPTV features. The ViSTA-TV project is hence in the position to compute real-time vieweship statistics and content-based recommendations.
