  5. Select specific sources • Filtered list • Add user defined sources • Group features by source • Type==colour • Highlight start-end Jalview DAS Client Functionality DAS ANNOTATION SERVERS • Query matches ID to Authority • Map to local reference frame • Mouse over for feature name, links and scores

  7. What WeWant From DAS • Consistency • DAS specifications (e.g. Range Queries) • Ontology • Enable annotation analysis • Compare features from different sources • Feature specific analysis – e.g. ‘DOMAIN’ • Make sense of scores + extra properties • Reliability • Registry: Dead Server Detection • Last Validated Property • High Volume Queries • Come Back Later • Bulk Requests
