Outline
• GIGAS Project
• SIF European Team
• GIGAS interoperability achievements:
– Recognized obstacles
– Recommendations
© 2008 GIGAS Consortium http://www.thegigasforum.eu
Promotes the coherent and interoperable development of the GMES, INSPIRE and GEOSS initiatives through their concerted adoption of standards, protocols, and open architectures
Start date: June 2008 End date: May 2010
GIGAS - GEOSS, INSPIRE, and GMES an Action in Support

SIF European Regional Team Implementation
GIGAS helped to constitute the Team
This objective is in the scope of the project
The SIF European Team is implemented in two phases:
1. A starting and preparatory phase;
2. A regime phase.
Structure and Roles
Sector Experts
discuss the Regional
Team positions
carry out
the tasks assigned by SIF
Lead
The lead serves as the regional representative on the SIF
Executive Committee
The Executive Committee supports the lead
The committee may be structured in secretaries

GIGAS committment
GIGAS has devoted a specific task to
explicitly set-up the European SIF team
foster the sustainability of the European SIF team beyond the GIGAS project duration
promote the participation of European actors outside GIGAS to the European SIF
promote the registration of, European or not, standards used by INSPIRE and GMES
promote the registration of, European or not, standards used by FP7 projects
GIGAS INTEROPERABILITY ACHIEVEMENTS
The Approach
Four subsequent steps:
monitoring, comparison, discussion & consensus, and influence &
shape.
This process will be iterated twice in the course of the
project (loop1 and loop2).
Recommendations are made towards the converging
requirements for recognized interoperability obstacles
The Approach
The following set of thematic areas or themes has been
addressed:
Architecture
Cross-initiatives scenario deployment plan
Catalogue, meta-data and discovery
Data access and processing
Data harmonisation and semantic interoperability
User management

Catalogue, metadata and discovery
To Whom (actor) Recommendation (action)
INSPIREINSPIRE, GEOSSGEOSS and GMESGMES technical teams
• Reach interoperability between catalogue interoperability between catalogue service solutions
• Better fulfill discovery requirementsfulfill discovery requirements• Short-term step: extend the CIM package extend the CIM package to
make it interoperable with the INSPIRE ISO Application Profile of CS-W
• Longer-term step: set up ebRIM extension set up ebRIM extension packagespackages for metadata discovery reflecting its own user view on metadata
Catalogue, metadata and discoveryTo Whom (actor) Recommendation (action)
INSPIREINSPIRE, GEOSSGEOSS and GMESGMES technical teams
Provide standardized access to other types standardized access to other types of geographic resourcesof geographic resources, through standardized ebRIM extension packages:
• Feature catalogues;• Application schemas;• Geodetic codes and parameters• Portrayal information• Feature concept dictionaries, thesauri,
glossaries and other registers of terms• Data quality measures• Ontologies• Code lists• Object identifier namespaces• Units• Data specifications• Encoding schemas
Catalogue, metadata and discovery
To Whom (actor) Recommendation (action)
INSPIREINSPIRE, GEOSSGEOSS and GMESGMES technical teams
Consider the use of the OASIS RegRep OASIS RegRep standard standard and/or the OGC RegRep profileOGC RegRep profile
Data Access and Processing
To Whom (actor) Recommendation (action)
OGCOGC, ISO/TC211ISO/TC211and CEN TC287 CEN TC287
Support SOAP/HTTP-POST binding SOAP/HTTP-POST binding according to INSPIRE IR, in addition to KVP/HTTP-GET bindingKVP/HTTP-GET binding
OGC OGC OWS Common 1.2 SWG
Evaluate the opportunity to support asupport a language parameter to set the natural language parameter to set the natural languagelanguage used for request and response
INSPIRE INSPIRE Network Services Drafting Team
Support metadataURL metadataURL that would point on to "ISO 19115:2003ISO 19115:2003" or "FGDC:1998FGDC:1998" metadata typemetadata type
Data harmonisation and semantic interoperability
To Whom (actor) Recommendation (action)
INSPIREINSPIRE Consolidation Team
Include actual O&M standard O&M standard in the INSPIRE Generic Conceptual Model
GMESGMES Fast-Track Service Projects
Adopt O&M-based information models and O&M-based information models and servicesservices
GEOSSGEOSS SIF Endorse the O&M standardO&M standard
GEOSSGEOSS ADC Adopt a framework based on O&Mframework based on O&M
Second LoopGIGAS has been working on the second loop of analysis.
New recommendations will be released before the end of 2009
The analyzed topics are the same of the first loop:
Architecture
Cross-initiatives scenario deployment plan
Catalogue, meta-data and discovery
Data access and processing
Data harmonisation and semantic interoperability
User management
OutlookGIGAS runs until mid 2010 as a project
GIGAS Business model and exploitation plan identifies measures needed to make GIGAS sustainable
Continue to improve the bi-directional communication with stakeholders
Embed GIGAS elements in existing forums
Identify “champions” that take willing to continue activities and maintain GIGAS-initiated activities
Identify elements that would require further funding
