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

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?
