Automatic Publication of Open Data from OGC Services: the Use Case of TRAFAIR Project

This work proposes a workflow for the publication of Open Spatial Data. The main contribution of this work is the automatic generation of metadata extracted from OGC spatial services providing access to feature types and coverages. Besides, this work adopts the GeoDCAT-AP metadata profile for the description of datasets because it allows for an appropriate crosswalk between the annotation requirements in the spatial domain and the metadata models accepted in general Open Data portals. The feasibility of the proposed workflow has been tested within the framework of the TRAFAIR project to publish monitoring and forecasting air quality data.
