Presentation Transcript

  1. Distributed Portals for Physics CRIS2002, Kassel, 29-31 Aug 2002 Thomas Severiens, severiens@isn-oldenburg.de

  2. What are Distributed Portals? • Knowledge in Physics is produced spread all over the world, even away form earth. • Information is published in a distributed way • Institutional Webserver • Online Journals • Print-only Journals • Information is available in different genres • Refereed articles • Peer-reviewed online-publications • Software • Datasets

  3. What are Distributed Portals? • Portals collect existing information form different sources • Portals present information in a common desktop • Separation of content and layout • Distributed Portals • Collect existing content from distributed sources (web-server) • Extract content from layout • Meta-information required

  4. Distributed Workforce • Distributed Content • Biggest example is the Web... • Distributed Workforce • Much more complicate • Quality-problem • Problem of continuity • Problem of politics and interests • Charter • Define common goals

  5. Distributed vs. Centralised • Centralised • High information structure • Common layout • Easy navigation through the information • Distributed • Up to date information • Low budget implementation • Good information coverage

  6. Distributed Portals – a technical view Portal Portal • Collecting module • Content extractor • Portal • Mirror system ? Portal Content extractor Collector Source A Source B Source C

  7. Distributed Search-Engines SINN-Project by DFN e.V. http://www.isn-oldenburg.de/projects/SINN/ Common Search XML-Query Search-Engine A Search-Engine D Search-Engine B Search-Engine C

  8. Examples of Portals in Physics • PhysNet (distributed portal) • ProPhysik.de (centralised portal) • Fachwelt-Physik (distributed portal)

  9. PhysNet www.physics-network.org

  10. PhysNet www.physics-network.org • Over 5.300 links of Physics Departments and Document-Collections • Service maintained in 8 countries on 4 continents • Web-Sites mirrored on 10 servers all over the world • Approx. 25.000 users every month • 16 members ((inter)national Physical Societies)

  11. ProPhysik.de

  12. Fachwelt-Physik www.fachportal-physik.de

  13. Fachwelt-Physik • Bilingual: English and German • Views: • Mozilla-based browser • Print-out version • Text-only version • Robot-optimised version with metadata • Maintained at numerous sites

  14. Future Focuses in this Field • Development and implementation of interfaces for distributed search-engines • Development of new services • Continuous maintenance of running portals
