  • 09:00 – 13:00: Consolidation per WP and task. Each WP leader presents a summary of discussions of Day 1, and leads the WP discussion


  • WP1
    • T1.1
      • Elena and Andreas to check with Oscar the status of the Sensor Network Ontology (see [1])
      • JSI, EPFL and UPM to assess the usage of the Sensor Network Ontology for providing descriptions of sensor sources and to publish this metadata in RDF (see [2])
      • Elena and Andreas to investigate alignment between Sensor Network Ontology and geospatial vocabularies developed in WP2/WP4 (see comment about mappings at [3])
      • JSI to provide update at next meeting on research work related to text streams
      • JSI to publish tagging results (referencing Cyc) as RDF

      • UPM to send examples of RDF stream data to Elena and Andreas (see discussion in [4])
    • T1.2
      • JSI will work on both sensor and text data (Wikipedia dump, streams of Wikipedia edits, data from Spinner3)
      • JSI to provide update at next meeting on research work related to T1.2
      • Links to FUB's work in WP2 (popular/interesting DBpedia concepts) and to the work of Pablo on linking textual descriptions to DBpedia concepts. FUB to provide update at next meeting
    • T1.3
      • EPFL to provide introductory tutorial and research roadmap to WP1 partners
      • EPFL to assist JSI in using GSN middleware
