"The GeoWS approach is to enable search, discovery, and access by
similarly constructed URLs containing a traditional directory structure
and query parameters in the URL. Each GeoWS partner has a base URL from
which their services can be accessed. For instance, the base for GeoWS
compliant services at IRIS is http://service.iris.edu/fdsnws. Specific services and versions are available under the base URL such as /event/1
for the IRIS event service version 1. This can be followed by a series
of parameters that provide constraints for the query. By default,
information is returned as XML but to aid usability GeoWS services also
supports easily understood, simple text content.
We have all heard that researchers spend 80 to 90% of their time and
effort finding and accessing needed data for their specific research
problem and only 10% actually doing science. The fundamental goal of
the GeoWS Building Block is to provide more uniform ways to discover,
access, and use data from various earth science data centers. The GeoWS
strategy is to promote the use of similar web services as methods of
interacting with domain data centers. While the standardization of the
space-time query for discovery is a high priority, the GeoWS approach is
flexible enough for the general approach to be implemented at all of
the GeoWS data centers on a variety of domain-specific data sets. Very
deliberately, the GeoWS primary partners include centers from solid
earth, atmospheric and ocean sciences, which represent the largest
sections of the GEO Directorate at NSF, along with secondary partners
from other geoscience-related disciplines.
GeoWS will benefit a wide range of scientists by reducing the burden
currently required to discover, access and use data across multiple
scientific domains. While the services can be accessed directly at the
providers’ service locations, GeoWS is also working closely with two
other Building Block proposals: the CINERGI Building Block (http://earthcube.org/group/cinergi) that serves as an EarthCube wide registry of services as well as the BCube (http://earthcube.org/group/bcube) building block that offers a brokering capability and a single portal through which the GeoWS data assets can be accessed."
