INSPIRE – Who does What
Discovery service GeoNetwork
View, Download, InvokeSD, Transformation Service GeoServer
INSPIRE Discovery Services 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
INSPIRE View Services GeoServer
Historically well supported WMS 1.1.1
GeoServer Stable 2.1.x Supports WMS 1.3 Ordnance Survey (UK) funded the work
INSPIRE compliancy still partial Harmonized Names (available since 2.2.0 beta)
SOAP Support missing (recommended, not mandatory)
Scenario 2 not supported
Partial support for multilingualism
INSPIRE Community Extension Separate plugin
Plugs-in additional fields for Multilingualism and Service Metadata
INSPIRE View Services GeoServer
Language support:
Single language declaration support
Limitations
No multilingual metadata on layers
Missing localized support for exceptions
Missing localization support for contents (e.g., GetFeatureInfo, GetMap labels)
Robust support for Mandatory CRS (ETRS89)
Support for Mandatory Encoding Formats (PNG, GIF)
Support for SLD 1.0 solid and mature
Many Additional Vendor Options
INSPIRE View Services GeoServer
Support for SE 1.1 present
extra operations available in SE 1.1 and not in SLD 1.0 are not supported
Some of the above are available as SLD 1.0 vendor extensions (same functionality, different syntax)
INSPIRE View Services GeoWebCache
Full support for WMTS 1.0 (tiled view services)
Harmonized names possible
INSPIRECRS84QUAD tile matrix set not built-in, but manually configurable
Missing INSPIRE extensions:
WMTS Capabilities document does not contain the required INSPIRE extensions (WMS-C do though)
No layer metadata links
Internationalization support missing
No SOAP support
INSPIRE Download Services GeoServer
GeoServer 2.2.0 beta first release to support WFS 2.0 and GML 3.2.1 IGN France Funding
SOAP supported
Missing some functionalities
Standard Capabilites Extension missing
Local and Remote Resolve
GetPropertyValue Interactions with AppSchema/Complex Features
Basic Workflow for Complex features Store original datasets in ad hoc schema database
Generating Object-Relational mappings
On-the-fly output transformations
INSPIRE Coordinate Transformation Services - GeoServer
GeoServer provides coordinate transformation tools with the gs:Reproject WPS process
Requires some changes to become compliant
Name change
List supported SRS
Use different mime types for GML
Add “test transformation” mode (does not actually transform, checks only if possible)
INSPIRE InvokeSD Services GeoServer
GeoServer Support OGC WPS 1.0.0
Interaction with external WFS and WCS
Automatic Ingestion of produced data
Basic process chaining is supported
Interaction with BPEL/BPMN engine to be tested

No INSPIRE!
Open Data
Tremendous push for business and innovation
Bottom-up process
Current Infrastructures shortcomings
Focus on data rather than on services
Mostly unidirectional
Split between geospatial and non geospatial
Interoperability between Hubs is an open point
There’s room for improvement
INSPIRE
Top-down process
Works by imposition
Complexity, Complexity, Complexity
We really needed more docs to read!
Adapting to INSPIRE is expensive
Existing products
Existing infrastructure
Existing data repositories
Real world moves faster than standardization bodies
Open Data provides momentum, let’s use it!
Conclusions
We work for people
People ask for more data & services not more rules
Complexity generate confusion
Confusion generate failures
Innovation
development of new values
solutions that meet new requirements
inarticulate needs
old market needs in new ways
Open Data initiatives are fostering innovation
INSPIRE does generate business, but innovation?

INSPIRE
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)
INSPIRE – Network Services
Discovery Services
View Services
Download Services
Transformation Services
Invoke Spatial Data Services
Rights Management Layer
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
INSPIRE – Download Services
Account for copies of spatial dataset, or parts of them to be downloaded and/ accessed directly
Predefined Dataset (or part) VS Direct access
Presence of Query Capabilities
Different Discovery Metadata
Based on OGC WFS 2.0 and ISO/DIS 19142, 19143 for Direct Access
May allow WFS 1.1 in the future
Support for European CRS is Mandatory (See Annex I of directive)
INSPIRE – Download Services
Support for GML 3.2.1 is Mandatory
SOAP Encoding is suggested
Multilingualism Support is key
Support for the Temporal dimension is Mandatory
Support for Vector Data is rather mature
Support for Raster Data is unclear
WCS 1.1.2? WCS 2.0?
INSPIRE – View Services
Display, Navigate, zoom in/out, pan or overlay viewable dataset and legend information
Based on OGC WMS 1.3.0 – ISO 19128 with OGC SLD and SE
INSPIRE Profile
WMTS 1.0.0 for tile services with INSPIRE extensions
WMS 1.1.1 (INSPIRE PROFILE) is also acceptable
2 Available Scenarios Scenario 1: GetCapabilities document is extended with a link to a
Catalogue
Scenario 2: Extra elements are embedded into the GetCapabilities document itself
INSPIRE – View Services
Support for European CRS is Mandatory (See Annex I of directive)
SOAP support is suggested
Support for the Temporal data dimension
Mandatory output formats for Maps are PNG and GID
Multilingualism Support is key
INSPIRE – InvokeSD Services
Invoking individual spatial services as well as combinations of them
synchronously or asynchronously
Middleware per processing
Technical Papers recommend OGC WPS as basic building block
BPEL is recommended between the others for Service Chaining and Workflow
SOAP should be mandatory
IR and TG not available yet
