Kalypso Simulation Platform
 
Kalypso is a modeling and simulation platform for GML-based models. It is primarly
developed to be a user friendly tool for the simulation of hydrological and hydraulic
numerical models. Thanks to Kalypso's underlying generic approachs of the GML
implementation, one can use the platform to handle GML models of arbitrary nature.

Kalypso consists of a Rich Client application which lets the user visualize and edit
GML data in a generic way (both GML 2 and 3 versions are supported) and is also a
client for several OGC Webservices (WMS, WFS, SOS). On the other hand, Kalypso brings
a set of artifacts for a service oriented architecture in order to support gml
processing.

Kalypso parses GML application schemas including depending ones such as the GML base
schemas itself into a strong feature- and property-typed system by building on top of
standard XML techniques such as SAX and Java API for XML-Binding.

Kalypso is LGPL open source and among others it is based on the Eclipse Platform and
deegree. Please see http://www.kalypso.wb.tu-harburg.de.

Introduction
------------
Kalypso is a modeling and simulation platform for GML-based models. It is primarly
developed to be a user friendly tool for the simulation of hydrological and hydraulic
numerical models. Thanks to Kalypso's underlying generic approachs of the GML
implementation, one can use the platform to handle GML models of arbitrary nature.


Kalypso Rich Client Application
-------------------------------
Kalypso consists of a Rich Client application which lets the user visualize and edit
GML data in a generic way (both GML 2 and 3 versions are supported). Beneath generic
GML views and editors such as a map view, table view and tree view, other views can
be registered to Kalypso via a plugin-interface for named feature types. This enables
Kalypso for example to support GML-based modeling of river profiles (aka
cross-sections) via a registered Observation-profile editor for a river-profile feature.

In order to achieve a strong (feature-)type system, Kalypso parses GML application
schemas including depending ones such as the GML base schemas itself into a strong
feature- and property-typed system by building on top of standard XML techniques such
as SAX and Java API for XML-Binding. Kalypso's schema parser supports a wide range of
XML features such as complex types, groups, includes, imports and substitution
groups. Higher level GML types such as Observations and Measurements are supported as
well in a generic way.

At the same time, Kalypso is a client for several OGC WebServices? such as WMS and
WFS. The development of an SOS client is being undertaken as well.


Kalypso-Services
----------------
Kalypso brings a set of artifacts for a service oriented architecture. It consists of
server applications whith generic support for gml processing. On top of this
infrastructure, special numerical models have been implemented. Legacy modeling
applications have been integrated into Kalypso's Model Plugin architecture,
suppressing the presence of heterogenous GUI front-ends and distributed
installations. Further GML based processes are in construction and an adoption of the
OGC Web Processing Service interface is under consideration.


Kalypso-API
-----------
Kalypso is LGPL open source and among others it is based on the Eclipse Platform and
deegree. The sources and a developer portal are available at
http://www.kalypso.wb.tu-harburg.de. For a benefit of semantic interoperability we
want to encourace developers and model designers to use strong typed GML application
schemas and applications. As the sources are structured in a modular way, the source
code for GML-processing can be used also separetely from the GUI-part.

Kalypso is under active development and currently provides user interfaces for
several numerical (hydrological and hydraulic) models for various river basins in
Germany. Furthermore three different Decision Support Systems with a strong accent on
ecological information management are based on Kalypso's API.
