GNIP 45 INSPIRE extension
Overview
Georg Ramler / Juergen Zornig / Angelos Tzotsos / Paolo Corti at the OSGeo Code Sprint 2014 Vienna Assigned to Release
2.1 - 2.2
Draft proposal
Motivation
It is proposed to add basic INSPIRE functionality to the Geonode portal solution.
INSPIRE needs basically three types of services to provide conformity:
Editing:
- Metadata Editor that allows to create and manage INSPIRE conformant metadata
Publishing:
- View Service: Provides the ability to view the available data
- Discovery Service: Provides the ability to search for available data via metadata
- Download Service: Provides the ability to download (pre-defined) data
Proposal
INSPIRE Implementing Rules for metadata: http://inspire.jrc.ec.europa.eu/documents/Metadata/MD_IR_and_ISO_20131029.pdf
INSPIRE Metadata is based on the ISO 19115 metadata standard. INSPIRE is sometimes more demanding and some fields have defined value domains. A user needs extensive support by the UI of the metadata editor to conveniently create or manage an INSPIRE conformant metadata record.
INSPIRE Implementing Rules for discovery service: http://inspire.jrc.ec.europa.eu/documents/Network_Services/TechnicalGuidance_DiscoveryServices_v3.1.pdf
Discovery functionality is already provided by Geonode via pycsw, that allows to retrieve INSPIRE conformant metadata and also provides an INSPIRE conformant CSW interface.
INSPIRE Implementing Rules for Download Service: http://inspire.jrc.ec.europa.eu/documents/Network_Services/Technical_Guidance_Download_Services_v3.1.pdf
A Download Service can be built in two different ways:
- Pre-definded datasets:
The data is provided in different formats and CRS combinations in a pre-built downloadable packages. The service itself is provided as multiple GeoRSS-Atom feeds. There is one so called "Download Service Feed" the contains basic information about available datasets. Each dataset is maintained in a so called "Dataset Feed". The "Dataset Feed" provides information about the individual dataset and the links to the pre-built download packages. The "Download Service Feed" provides links to the "Dataset Feeds".
A Download Service with pre-defined datasets also has to provide an OpenSearch Service to find datasets in the Download Service itself and also provides the availability to discover the available formats and CRSs and to download the found datasets.
