INSPIRE: about

The INSPIRE directive aims to create a European Union (EU)

spatial data infrastructure.

This will enable the sharing of environmental spatial information

among public sector organisations and better facilitate public

access to spatial information across Europe.

The INSPIRE directive came into force on 15 May 2007 and will

be implemented in various stages, with full implementation

required by 2019.

Institutional site: http://inspire.jrc.ec.europa.eu/

INSPIRE: about

Infrastructure for Spatial Information in the European

Community 2007/2/EC Directive, 14/03/2007

Fully in place by 2019

Implementing Rules and Technical Guidance to implement

EU-wide Interoperable SDIs IR are legally binding

TC are not legally binding

Main Aspects Covered Metadata

Network Services

Data and Service Sharing

Data Specification

Monitoring and Reporting

Maximum Reuse of existing standards (OGC, ISO, W3C)


November 14th 2012

INSPIRE: Who does What

Discovery service GeoNetwork

View, Download, InvokeSD, Transformation

Service GeoServer


November 14th 2012

INSPIRE: discovery services

Discovery of spatial dataset and services

Provide operations on services

query about service capabilities

register other federated Discovery Services

Provide operations on metadata

search

update (both push and pull modes),

perform federated searches

Based on Metadata specs from ISO

TG requires CSW 2.0.2 ISO AP as starting point


November 14th 2012

INSPIRE: discovery services in GeoNetwork

GeoNetwork implements CSW 2.0.2 ISO Profile

INPIRE extended constraints in metadata should be

explicitly enabled in GeoNetwork

Complies with almost all main requirements in Metadata

Implementation and Discovery Services

Main compliancy issues in:

Handling federated catalogues

in Discovery Service Metadata and Link Discovery Service

operations

Federated metadata retrieving

no CSW, only Z39.50

Publishing in pull mode

matching CSW Harvest operation in GN is not stable yet


November 14th 2012

INSPIRE and ISO19115/19139

INSPIRE supported metadata are based on

• ISO19115/19139 (metadata)

• ISO19119 (services)

There are some differences in constraints on metadata

elements between ISO19115 and INSPIRE.

The use of the INSPIRE guidelines to create INSPIRE

metadata ensures that the metadata is not in conflict

with ISO 19115. However, full conformance to ISO

19115 implies the provision of additional metadata

elements which are not required by INSPIRE.


November 14th 2012

INSPIRE support in GeoNetwork

• Editing view that underlines INSPIRE required

elements

• Easy check and insertion of INSPIRE required

elements

• Schematron rules to check for INSPIRE conformance

• Search using INSPIRE codelists

• Extended CSW queryables fields to match INSPIRE

requirements


November 14th 2012

RNDT: about

• RNDT («Repertorio Nazionale dei Dati Territoriali») is

the Italian national metadata catalog - instituted in

2005 and managed by DigitPA - whose purpose is to

facilitate the dissemination of the data of general

interest, available in the public administration

agencies at different levels.

• RNDT is based on ISO19115, 19119 and 19139

standards.

• Conformance to the RNDT metadata standard should

ensure conformance to INSPIRE guidelines


November 14th 2012

RNDT support in GeoNetwork

GeoSolutions’ first work with RNDT was with a

GeoNetwork customization for CSI Piemonte.

Issues:

• Some RNDT interpretations of ISO19139 differ from

GeoNetwork standard implementation.

• Some constraints in RNDT are looser than ISO19139
