A year after the release of 4.0, the Sensor Web community is pleased to announce the

52°North SOS 4.2 Release!

A downloadable zip archive of the release contains the sources, as well as the binaries. Release requirements, installation and configuration information are documented in the 52°North wiki.

Due to some adjustments in the database model, we recommend reading the database update information in the 52°North wiki.

Core features and improvements

We have implemented the following additional features (NEW) and improvements.

• Integrated work performed in the INSPIRE SOS context (NEW)
  • INSPIRE Download Service extension
  • coordinate transformation
  • multilingualism
• Implemented support for OGC SensorML 2.0 (NEW)
  • InsertSensor with OGC SensorML 2.0 description
  • Query OGC SensorML 2.0 sensor descriptions
  • Generate OGC SensorML 2.0 description from available data
  • Convert OGC SensorML 1.0.1/OGC SensorML 2.0 to requested format
• Implemented support for Efficient XML Interchange (EXI) 1.0 binding (NEW)
• Transactional operations are disabled and Transactional Security is enabled by default
  • To avoid the unwanted manipulation of SOS data via the transactional operations in the default 52°North SOS, we have disabled the transactional operations by default. The operations affected are:
    • InsertSensor
    • InsertObservation
    • InsertResultTemplate
    • InsertResult
    • UpdateSensorDescription
    • DeleteSensor
    • DeleteObservation
  • Read how to enable the transactional operations in the Transactional operations administration section of the 52°North wiki. One must enable the transactional operations in order to insert example data into the database.
  • Read how to disable or modify the Transactional Security in the Transactional Security features section of the 52°North wiki.
• Use of doubles instead of BigDecimals for numeric observation values
  • The BigDecimal precision will be lost in gml:MeasureType which is defined as xsd:double. This is an IEEE double-precision 64-bit floating-point number. For more information read this discussion.
• Updated 52N XML Common to 2.0.0
  • SamplingFeature schema fixed multiplicity of sampledFeature from 1..1 to 1..*, was an issue in the OGC XML schema.

For further information about the functionality, improvements and fixed issues, please read the RELEASE-NOTES or visit the SOS GitHub issue page and the 52°North SOS 4.x wiki page.

A short preview of future work

• Support for Air Quality Data e-Reporting encoding
  • For more information about Air Quality Data e-Reporting see the AQPortal
• Support for flexible identifier
  • Allows the use of human readable names as identifier
  • In this case the value of the “name” column is used as identifier and requires unique names.
  • Affected SOS elements:
    • Offering
    • Procedure
    • ObservableProperty
    • FeatureOfInterest
• Integration of the RESTful API and the Sensor Web JavaScript client
• Integration of sos.js for SOS 1.0.0 operations.
• …

 

Many thanks to all 52°North SOS contributors for their enhancements and improvements, and to all users for their feedback!
