After 18 months of operation, cooperation and active participation on meetings in the research area of Knowledge Web is in place. In 2005 all WPs met at the Joint Knowledge Web Research meeting on 24th-25th January 2005 at Hannover, Germany and the Joint Knowledge Web Research meeting following the ESWC 2nd European Semantic Web Conference, ESWC 2005, in Heraklion, Crete 2nd-3rd May 2005.
Before M12 the area managers had emphasized additionality instead of duplication of effort, and have encouraged cross collaboration between WPs, the SDK cluster, the WSMO projects and other activities. To strengthen the cross-WP-fertilization we introduced for both meetings in 2005 a new form in addition to regular WP meetings: so-called themed research meetings (aka. join sessions or concertation meetings). For each themed meeting the major topic of one research WP has been highlighted as theme, in January this had been "Web Services" and in May this had been "Language Extensions". Operationalization of a themed meeting consists of a series of bi-lateral meetings of the highlighted WP with all the remaining ones.
In this deliverable we present a brief overview of the research advance achieved so far which consists of summaries of the results so far achieved in each research work package (WP2.1 Scalability, WP2.2 Heterogeneity, WP2.3 Scalability, WP2.4 Web Services and WP2.5 Language Extensions) and summaries of bi-lateral meetings among different work packages.
