HSLayers is an open source JavaScript web mapping framework designed for INSPIRE. It uses a client-side solution with some supporting server-side scripts. Key components include patches to OpenLayers, HSLayers classes that extend functionality, and server scripts for proxying, printing, and storing application state. Future plans include expanded support for styling layers and sensor data.
