Three new Journal Articles on Sensor Plug & Play

Posted in 52°North, Semantics, Sensor Web

I’m happy to announce that we got three new articles accepted for publication:

  • Diaz, L., A. Bröring, D. McInerney, G. Liberta & T. Foerster (2013, accepted): Publishing Sensor Observations into Geospatial Information Infrastructures: A Use Case in Fire Danger Assessment. Environmental Modelling & Software. [paper]

In this article, an approach is presented to improve the registration of sensors and the publication of their observations via the Web Processing Service (WPS) and the Sensor Observation Service (SOS) interface. Therefore, those services are combined with our Sensor Interface Descriptor (SID) concept. The approach is evaluated by applying the developed approach to the example of integrating in-situ weather observations into the European Forest Fire Information System (EFFIS) for assessing fire danger in Spain.

  • Malewski, C., A. Bröring, Patrick Maué & K. Janowicz (2013, accepted): Semantic Matchmaking & Mediation for Sensors on the Sensor Web. IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing (JSTARS). [paper]

In this work, we introduce our implementation of a rule system that supports complex mediation and mappings of sensors to Sensor Web services. This matchmaking system is part of our Sensor Bus project. This work equips us with the semantic capabilities for achieving real sensor plug & play.

  • del Rio, J., D.M. Toma, T.C. O’Reilly, A. Bröring, D.R. Dana, F. Bache, K.L. Headley, A.Manuel, D.R. Edgington (2013, accepted): Standards-based Plug & Work for Instruments in Ocean Observing Systems. IEEE Journal of Oceanic Engineering (JOE). [paper]

This work deals with sensor integration in the Ocean’s domain. We describe an approach to plug & play sensors by combining our Sensor Interface Descriptor (SID) concept with the new OGC standard known as the PUCK protocol. PUCK enables storage and retrieval of the SID file from the sensor itself. We demonstrate and evaluate our approach by applying it to three commonly used marine instruments in the OBSEA observatory test bed.

The Institute for Geoinformatics (ifgi) is looking for highly motivated candidates to fill two positions, one at the post-doc level and one at the PhD student level. Both positions are fully funded by the Linked Data for eScience Services (LIFE) project – a two-year project funded by the German Research Foundation, jointly carried out by the Semantic Interoperability Lab (MUSIL) at ifgi and the University Library at the University of Münster.

If you are interested, please find more information here.

The application process is open until October 15, 2012 or until the positions are filled.

52°North seeks student applications for the Google Summer of Code

52°North is thrilled to announce that it has been chosen to be a mentoring organization for this year’s Google Summer of Code (GSoC)!  GSoC is a global program that offers students stipends to write code for open source projects. Google pays the stipend recipient $ 5.000,- for 3 months of software development for 52°North this summer. A mentor from a 52°North partner organization supervises the student during this period.

As such, we now look for students who are interested in writing code for various 52°North projects. The overall goals are to improve usability of products and to extend the user base to new domains.

If you are interested in writing code for software developed by the 52°North communities, please have a look at Student Application opens on March 26, 2012 at 19:00 UTC. The deadline is April 6, 2012 at 19:00 UTC.

This summer, flip bits not burgers with 52°North!

Any questions? Please contact Daniel Nüst ( or join us at ** *#52north*.

New Framework for Semantically-enabled Sensor Plug & Play

August 2nd, 2011 @ 14:45 by Arne Bröring
Posted in Semantics, Sensor Web

In a joined effort of the 52°North Sensor Web and Semantics communities, we have developed a new framework that enables the plug & play of sensors with the Sensor Web based on Semantic Web technologies. The design of the developed architecture got just published in a journal article.

The developed framework includes mechanisms for the automated semantic mediation between characteristics advertised by new sensors and the defined requirements of sensor web services. The semantic mediation framework is combined with (i) our Sensor Bus, a publish/subscribe architecture to establish message-driven communication between sensors and services, and (2) the 52°North interpreter for Sensor Interface Descriptors, used as a generic driver mechanism for sensors.

To demonstrate this development, we applied it in an oil spill use case where marine sensors measuring for example water temperature and salinity need to be integrated on-the-fly with a Sensor Observation Service. As the figure below illustrates, the semantic matchings of various sensor / service properties need to be assured before the sensor can be connected with the service.
For being able to “talk” to the utilized sensors, we developed according instances of the Sensor Interface Descriptor model for the different marine sensors using our SID Creator tool.
