1. ORFEUS Torild van Eck & Chad Trabant Why is ORFEUS interested in distributed OO computing? Presentation ORFEUS Present status Orfeus Data Center ORFEUS dreams and reality

2. Core activity: ORFEUS Data Center Objective: European earthquake high quality waveform data archive Policy: Open data (emphasis on research community) Requirements: Homogeneous format, complete description (SEED) Systematic archives (events and continuous) Easy and rapid data access/search ORFEUS Organizations and Research Facilities for EUropean Seismology European non-profit foundation that aims at co-ordination and promoting digital, broadband (BB) seismology in the European-Mediterranean area. [13 corporate founders, 64 (mostly) academic institutes]

3. Station siting (WG1) (chair: Josep Vila, Barcelona) Coordinating BB station siting in Europe and its surroundings. European BB station inventory. Overview BB sensors and data acquisition systems Technical Support (WG2) (chair: Damiano Pesaresi, Rome) Gather and disseminate technical information. Coordinate technical assistance on BB sensors and data-loggers. Mobile stations (WG3) (Chair : Paul Denton, Leicester) Maintain instrumentation inventory Coordinate data archiving and dissemination Seismological software (WG4) (chair: Manfred Baer, Zurich) Seismological Software Library (Unix, Linux, PC and Mac) Coordinate software developments within seismology. ORFEUS coordination activities http://orfeus.knmi.nl

4. Start date: November 1, 2000 MEREDIAN consortium: 18 participants End date: April 30, 2005 Goal:Initialize real-time waveform data exchange in Europe, make previously inaccessible data available to the research community, developing a distributed archive WP1: Improving and securing data archival WP2: Improving rapid cross border data exchange WP3: Developing a distributed European seismological archive WP4: Seismological software co-ordination Mediterranean-European Rapid Earthquake Data Information and Archiving Network The EC project MEREDIAN http://orfeus.knmi.nl/meredian

6. VEBSN (BB) stations in Europe and its vicinity (status 1/4/2003) Full information available on: http://orfeus.knmi.nl/VEBSN

8. ODC data holdings

9. ODC data pipeline

10. - available data (waveform, parameters, event, station, data information) - rapid access and search capabilities - analysis and integration with other geoscience data - automated creation of level 2 data Dreams or reality ? about research with seismological (waveform) data from anywhere? ORFEUS http://orfeus.knmi.nl/ ORFEUS Present involvement: BB-data production archiving exchange processing and analysis

11. Broadband (BB) stations in Europe (status 1/4/2003) Source: ORFEUS WG1 Full information is presently accessible in a database at: http://orfeus.knmi.nl

12. SP BB Source: ORFEUS/EMSC Stations in Europe and its Vicinity 1/7/2003

13. ORFEUS activities: Data production ORFEUS coordinates, but does not operate stations ORFEUS working group 1: “Station siting” - Inventories - stations siting/standards: - VEBSN and regional network coordination? - networking protocols? ORFEUS working group 2: “Technical Support” - instrumentation (sensors and DAS) - technical documentation and networking - data exchange technologies?

14. ORFEUS activities: Data exchange ORFEUS coordinates EuroMed BB waveform data exchange standardization of data exchange protocols: - SeedLink [waveform data], mostly (near) real-time applications Format (mini)SEED - AutoDRM [parameter and waveform data] non real-time applications Formats (GSE and SEED) - XML? format discussions MEREDIAN project (EC) provide assistance with: AutoDRM installation SeedLink plugins SeedLink implementation

15. ORFEUS activities: Data archiving EuroMed BB waveform event data EuroMed continuous data? Alternative 1: Central data archive Alternative 2: Distributed European Data Archive. How to realize this? NetDC Standardization of data archiving format: SEED [waveform data] Format conversion: GSE2SEED (Reinoud Sleeman) X2SEED conversion programs. MEREDIAN project (EC) provide assistance with: dataless SEED volumes [facilitate]

16. ORFEUS activities: Data processing and analysis ORFEUS working group 4 and ODC - Seismological Software Library [freely available software] - initiatives to coordinate developments: SeisComP [freeware, MEREDIAN] QuakeExplorer [freeware, Lomax/MEREDIAN] - involvement in developments for: Antelope [commercial] EarthWorm [freeware (+ Oracle, commercial)] Seisan [freeware] - coordinate data exchange mechanisms - where and when should we introduce OO standards? - should we coordinate OO programming? - specific OO web pages? Target public?

17. SP BB Source: ORFEUS/EMSC Seismic stations in Europe and its immediate vicinity Link this data to other geoscience data. How? What can ORFEUS do?
