INSPIRE services with GeoServer and HALE, where are we?

This presentation covers the progress made since last year's INSPIRE Conference with respect to the support for complex feature and the INSPIRE data specifications in GeoServer as well as the connection between HALE and GeoServer itself.

It also covers the ongoing work and the directions of future enhancements.
