32. Complex Features Support – The Good
GWF 2015, Lisbon
27th May 2015
 Official GeoServer extension
 Complex Features
 Multi valued attributes
 Collection of related objects in one XML
 Nesting of features (also Complex Features)
 Required by many Inspire schemas
• Mapping of SimpleFeatures
 to build Complex Features, that are compliant to a
given XSD
 Transformations through CQL
 Feature linking

33. Complex Features support
GWF 2015, Lisbon
27th May 2015
 Difficult to configure  no UI
 Manually create XML configuration files
 Reload Catalog for any change (trial and
error)
 Need for a graphical mapping tool
 Performance
 Getting good performance can be
difficult
 Data needs to be preprocessed
(denormalized)
 Optimized join on JDBC based sources
can help
The Bad
The Ugly

34. Complex Features – HALE at rescue
GWF 2015, Lisbon
27th May 2015
 Using HALE as a GUI editor for app-schema config
 No need to create a new GUI
 Seamless integration of HALE with GeoServer
 Implemented as a new type of Alignment Writer
 Needs to support most common HALE transformations
and translate them to app-schema mappings
• Tough work
• Will be done in steps
• Most common transformation firsts
• Hopefully, no need to manually edit the final result

35. Complex Features – HALE at rescue
GWF 2015, Lisbon
27th May 2015
 In the process…  Already Funded
 Improvements and bugfixes to HALE
 Improvements and bugfixes to GeoServer app-schema
 New schema/data formats for HALE  Spatialite
 New type of transformations for HALE (e.g.
ReprojectGeometry)
 Improvements to the app-schema mapping engine to get
a better integration
 Bonus Track  Funding Appreciated
 Integrate HALE ETL Engine in GeoServer
 Batch exports (Predefined dataset)
 Periodic batch
 Preprocessing for efficient publishing
