HALE 2.9.2: WFS-T Support and new Database Features

ON the road to HALE 3.0, we’ve release a maintenance release of HALE. In addition to making numerous fixes available to in a released version, 2.9.2 also sports two headline features:

Improved WFS Client + Transactional WFS Support

With this feature, you can publish GML to a transactional Web Feature Service, for instance for publishing INSPIRE data to a deegree server. We currently support are Transactional Web Feature Services following the OGC WFS 1.1.0 or WFS 2.0.0 specifications. There are two different providers for publishing to WFS:

  • Direct upload: Does a single request that starts as soon as the first transformed features are available. Use this option if you are sure the WFS can cope with the amount of data in a single transaction.
  • Partitioned upload: Partitions the transformed data before upload to be able to do multiple requests to the WFS-T for large data sets. The partitioning is done based on the references between features. Features that are connected are kept together so the WFS-T is able to retain those references.

Improved Database Reader/Writer

We’ve had a silently released database writer for PostGreSQL in HALE for a while, and due to popular request we’ve improved it a bit and provided official support and documentation.

PostGreSQL Configuration

Compatibility to FME and other fixes

We’ve also tested whether the FME Plugin for HALE still works with the most current FME versions (2014 SP3 and 2015) and can confirm it’s compatibility. You can thus combine both tools. For example, use HALE to do restructuring of complex data and encoding as GML, but use FME to read formats unsupported by HALE or to employ special transformers.

As usual, there has been a set of other improvements, for example to make the encoding of MultiSurfaces and complex aggregates more flexible.
