Why is ORFEUS interested in distributed OO computing?
• Presentation ORFEUS• Present status Orfeus Data Center• ORFEUS dreams and reality
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
SeismologyEuropean 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]
• 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
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 archivalWP2: Improving rapid cross border data exchangeWP3: Developing a distributed European seismological archive WP4: Seismological software co-ordination
Mediterranean-European Rapid Earthquake Data Information and Archiving Network
The EC project MEREDIAN

VEBSN (BB) stations in Europe and its vicinity
(status 1/4/2003)
Full information available on:http://orfeus.knmi.nl/VEBSN
ODC data holdings
ODC data pipeline
- 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 activities: Data productionORFEUS 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?
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 installationSeedLink pluginsSeedLink implementation
ORFEUS activities: Data archiving
• EuroMed BB waveform event data• EuroMed continuous data?
Alternative 1: Central data archiveAlternative 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]
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?

Link this data to other geoscience data.How? What can ORFEUS do?
