1 Purpose

The up to date standard in monitoring volcanic activity is to utilize multi-parameter data sets. Multi-parameter data sets by themselves result in high-dimensional, complicated data streams, which needs a flexible database and analysis system to handle these data. The special requirements of an easy to extend database not restricted only to seismology, which is additionally able to work in a multi-user, multi-institutional environment, leads us to adopt a new database called Seishub. As a first step raw or already processed data formats, parameter and meta-data delivered or produced by the different work packages were already identified. This led to a couple of data formats which will be supported by the Exupéry database (GeoTiff, SEED etc.). Another important point to be adressed by WP 3 is the visualization of results and data product through an easy to handle, slim, license free and platform independent GIS.

 

1.1 Theoretical background


XML and SQL structure.

SeisHub is a novel web-based database approach created for archiving, processing, and sharing geophysical data and meta data, particularly adapted for seismic data. The implemented database prototype offers the full functionality of a native XML database combined with the versatility of a RESTful Web service. The XML database itself uses a standard relational database as back-end.

 

 

This sophisticated structure allows for the usage of both worlds: on the one hand the power of the SQL for querying and manipulating data, and one the other hand the freedom to use any standard connected to XML, e.g. document conversion via XSLT or resource validation via XSD. This flexibility of the XML/SQL mixture introduced above enables the user to include parameters or results as well as meta data from additional or yet unknown monitoring techniques at any time. Additionally, SeisHub offers various access protocols (HTTP/HTTPS, SFTP, SSH), an extensible plug-in system, user management, and a sophisticated web-based administration front-end.

 

The SeisHub database is an open source project and the latest development release can be downloaded via the project home page.
