Ann Hitchcock writes "52°North publishes first stable releases - Quality assurance makes the difference! 52°North (http://www.52north.org/ )is proud to announce the first software stable releases which have successfully completed the 52°North quality assurance testing! As an open source software initiative, we emphasize quality management to ensure software's practical suitability and sustainability. This cross-sectional task is anchored in our organizational model and has evoked the creation of a Quality Management Task Force. This Task Force has taken over the task of defining, implementing and continually developing QM processes. Those processes necessary for the quality assurance testing of 52°North software are of particular interest to users and have been successfully applied in the past few months." Read more below. Their Mission makes is clearer: "52°North's mission is to advance the design, development and use of open source software in geoinformatics research, training and application. We will bridge the gap not only between research and application, but also between open source and commercial software."
52N Security System Version 1.1.
The first quality assured 52°North product was released the end of February 2006. The 52N SecuritySystem rel-1.1 was developed within 52°North’s Security Working Group. It provides protection/access control for OGC Web Services implemented in Spatial Data Infrastructures (SDIs). The components Web Authentication Service (WAS) and Web Security Service (WSS) enable the control of access to services such as Web Mapping Services (WMS) or Web Feature Services (WFS), thus allowing users to access only those layers of a service for which he/she is authorized. Access to controlled services via arbitrary desktop applications which support access to Web Mapping Services (e.g. ESRI ArcMap) is provided for by a Web Security Client (WSC).

Applications of the 52N Web Security System include the protection of internal geodata and geoservices, or those having limited public access, within otherwise freely accessible geodata-infrastructures and geoservice-infrastructures, as well as logging the use of services within an organization for recording internal performance.

Download the 52N Security Service rel-1.1 from our home page (http://www.52north.org/index.php?sw_releases). Register for the security mailing list at http://www.52north.org/mailman/listinfo/security.

52N Sensor Observation Service Version 2.0
The 52N SOS v2-00-00 was developed within 52°North’s Sensor Web Enablement (SWE) Working Group and successfully completed our quality assurance testing the beginning of March 2006. This quality assured open source software component implements the core profile of OGC’s SOS 0.1.4. draft implementation, thus enabling interoperable provision of geo-referenced measurement data. As a result, it is easily integrated into geodata-infrastructures and geoservice-infrastructures. In situ sensors (e.g. water gages), as well as remote sensing sensors can be used for data collection.

The 52N SOS V2-00-00 is also registered on OGC’s resource site as being the first product to implement the OGC SOS specification. Download the 52N SOS V2-00-00 from our home page (http://www.52north.org/index.php?sw_releases).

52N Sensor Observation Service Version 2.01
This quality assured update provides new features. It supports PostgreSQL 8.1 and provides improved memory handling. Up to 6000 Observations (approximately 6MB XML) were requested with the standard configuration of the Tomcat on our test server (1,5 GB RAM, 1,1 GHz). The same test with the former release yielded only 3000 observations. A DBFeeder framework has been implemented and supports the SOS provider by integrating observations into the underlying SOS data base. Download the 52N SOS V2-01-00 from our home page (http://www.52north.org/index.php?sw_releases) under software.

52N Web Notification Service Version 1.0
The quality assured 52N WNS v1-00-00 has just been released. This Java Servlet was also developed within 52°North’s SWE Working Group. It acts as a protocol transducer, executing and managing message dialogues between a client and one or more Web Service(s) for long asynchronous processes. The incoming XML encoded messages are currently translated to email (SMTP), short message service (SMS), fax, phone, HTTP POST and XMPP. SingleUser and/or MutliUser can register to receive either a Notification message (a one-way message) or a Communication message (an answer to the message received is expected). If the message is too long, for example for SMS, fax and/or phone, the WNS stores the message and delivers only a short description of where to get the full message. The 52N WNS will be integrated into the 52°North SWE Web Services Package?. It will be used by the 52N Sensor Planning Service (SPS) to communicate between the SPS and the sensor user and will provide the 52N Sensor Alert Service (SAS) with protocols not supported by the SAS.

What is 52°North?
52°North is an open source software initiative, founded on October 1, 2004 and shouldered by established institutions in the German and international geoinformatics scene. It focuses on the capture, analysis and visualization of spatial data within open spatial data infrastructures (SDIs). 52°North’s goal is to develop software components for spatial data infrastructures (SDIs). These software components are based on service oriented architectures whose integration layers are realized via OGC Web Services. This open membership organization strives to develop quality assured solutions which are methodically and technically innovative and go far beyond well established web mapping, as well as to establish these solutions in all areas of the geoinformation technology market. The software is released under the free software license GNU GPL v2 and is available free of charge for the general public from the 52°North web page (http://www.52north.org/ ).

52°North's mission is to advance the design, development and use of open source software in geoinformatics research, training and application. We will bridge the gap not only between research and application, but also between open source and commercial software.

ITC's GIS Software ILWIS Migrates to Open Source [+]
The OSGeo announce mailing list tells us the Integrated Land and Water Information System (ILWIS) GIS software migrates to open source with 52 North. From the announcement: "In order to create better opportunities for the reuse and deployment of GIS functionality in a wider community, the ITC directorate has recently decided to make current ILWIS software free of charge and to migrate it as such to open source software under the 52°North initiative." See related stories below to learn more about the 52 North initiative and where it stands to OSGeo. These comments on import cartography are also interesting.
Web Processing Service (WPS) Demos 1 comment [+]
Anonymous Voxel writes "An old (but still interesting) news from geoserver blog: Theodor Foerster, of 52North and ITC, has been leveraging GeoServer in his work on generalization of geospatial data using the new Web Processing Service specification. He recently posted some nice new work, including updates to the Web Processing Service web app, as well as a new WPS client written as a plug-in to uDig. Awhile ago he also did some prototypes of integrating the WPS with GeoServer, making the WPS a datastore that could be served out as WMS and WFS. It’s great to see new open source tools being built that can use and leverage the work we’ve done with GeoServer. You can see his work in action, with GeoServer, in the screencast that he’s also posted.

Eventually we’re hoping to be able to offer some integration between GeoServer and his WPS work, possibly as a plug-in to GeoServer that makes it really easy to install both, and to do common data configuration through our web gui. In the past we’ve also talked to the FROGS WPS community about possible integrations as well. Since we’re evolving GeoServer to be a platform it makes a lot of natural sense to be able to bring WPS in to the mix, in some form. It looks like the FROGS people are also leveraging Spring, which may help compatibility as well (we haven’t talked to them for awhile so I suppose we can just cross our fingers that they’re looking at what we’ve done). So if anyone has the time or the money to get a WPS integrated with GeoServer, let us know, as we’ve got some great pieces to work with."
