A network based datastore for geoscience data and its implementation.

 abstract = { Pursuing our contribution to the EU project “ProMine”1 to develop a comprehensive model for geo–data towards a geoscience information system of spatio–temporal geo–data our communication states the progress since last year’s gOcad meeting [Gabriel et al., 2010] with special emphasis on a network based infrastructure to handle spatio–temporal geological properties assigned to simplicial objects.
For the time being, the project includes a first extension of the database system PostgreSQL [pgSQL, 2011] for three dimensional geodata which we refer to as GST. Analogously to the well known open source extension for two dimensional geometries PostGIS [PostGIS refractions, 2010] , our extension employs the Simple Feature Standard [OGC 06-104r4] defined by the Open Geospatial Consortium(OGC) for communication. In order to reduce the amount of data required to be transferred to clients, extensions have been included to SFS+. Our approach is not restricted to extensions of PostgreSQL and will soon be applied to other database systems. The preference for PostgreSQL is owed to the request to deliver a first prototypical implementation of our data store. Future developments of the model will comprise explicit considerations of topology and time.
To meet the requirements of interoperability, this system shall include a webservice to provide geo–data in a service oriented architecture (SOA). The implementation of a web feature service (WFS) creates an interface to share geo–data with any other systems via GML [OGC 07-036]and GeoSciML [GeoSciML, 2010], and more recent markup languages inclined to geosciences.
A client-software is implemented both as gOcad–plugin as well as standalone application. Thus it is possible to access our GST, installed on a network server, from various clients simultaneously. Complementary implementing a WFS interface on client side will enable gOcad to retrieve data from any other web feature service. In general, Postgres Server (and others) and WFS will be implemented in such a way that they can be accessed via the internet. },
