[Live-demo] 52°North SOS in OSGeo Live DVD

[Eike Hinderk Jürrens]

Dear all,
I would like to propose the including of the 52°North SOS implementation
on the OSGeo-Live distribution.

The name of the project is "Sensor Observation Service implementation by
the Sensor Web Community of 52°North". The homepage is located here:
    short: http://52north.org/sos
    long:  http://52north.org/communities/sensorweb/sos/

The code is provided by GPL v2.0.

The Sensor Observation Service aggregates readings from live, in-situ
and remote sensors. The service provides an interface to make sensors
and sensor data archives accessible via an interoperable web based
interface. Four profiles are defined within the SOS specification: core,
transactional, enhanced, and entire. The current release (52N-SOS-3.1.1)
implements the core, transactional, and parts of the enhanced profile
comprising the mandatory operations:

    * GetCapabilities, for requesting a self-description of the service.
    * GetObservation, for requesting the pure sensor data encoded in
Observations & Measurements (O&M)
    * DescribeSensor, for requesting information about the sensor
itself, encoded in a Sensor Model Language (SensorML) instance document.

The transactional profile comprising of the following operations is
implemented, too:

    * RegisterSensor, for signing up new sensors.
    * InsertObservation, for inserting new observations for registered
sensors.

Additionally, the following operations are implemented:
    * GetResult, for periodically polling of sensor data
    * GetObservationById
    * GetFeatureOfInterest, for requesting the GML encoded
representation of the feature that is the target of the observation.
    * GetFeatureOfInterestTime

The current release implements the latest schema version (1.0.0).

The 52°North SOS that will be included on the Live DVD has been
available as a stable release for several months. It has been developed
during the recent years and has reached a stable and mature state.
Furthermore it has been applied in several projects (both European
research projects as well as productive systems deployed by different
customers).

The implementation of 52°North SOS provides a test client which comes
with predefined requests but can be used to send own user-defined requests.

We are planning a workshop which will use the 52°North @ FOSS4G 2011.

The contact person will be me: e.h.juerrens at 52north.org and I am
following this list.

We will provide a custom install script and we do not wish to include a
Windows and/or Mac installers.

The application requires postgresql + postgis + tomcat. As I remember
correct, the applications are already available on OSGeo Live DVD or
required by other projects, it will be no problem, to run the 52°North
SOS with 512 Meg of RAM.

Less than 30 MB are required by the SOS depending on the OS.

The SOS requires an own data set but this is less than 10 MB (being one
week of weather data with seven observed properties with a sampling rate
of 15 minutes encoded in sql statements). This can be shipped with OSGeo
or downloaded before.

Any questions/answers/pieces of information left?

Looking forward to your comments!

Kind regards,
Eike
