  1. The INSPIRE Network Services Drafting Team May 23, 2006, Paris • Slides prepared by: • Jean-Jacques Serrano, BRGM, France • Tapani Sarjakoski, FGI, Finland

  2. Objectives of our WS today and tomorrow The main objectives of this INSPIRE workshop are to: • Inform our members about the status of the work within the INSPIRE Drafting Teams (DTs) • Give our members the opportunity to comment on and influence the work of the DTs • Give our members the opportunity to report national developments relevant to the INSPIRE DTs • Understand the relationship and contribution of EuroGeographics and national activities to the INSPIRE DTs • Develop a EuroGeographics position on each DT

  3. Outline Network Services Drafting Team • 1- Objectives • 2- Members • 3- Deliverables • 4- Progress and issues

  5. Objectives of the Drafting team (1) • Objectives of all drafting teams • Analyse and review reference material provided by the SDICs and LMOs (Spatial Data Interest Communities, Legally Mandated Organisations); • Write the draft Implementing Rules • Provide recommendations and suggestions to the Consolidation team • Identify issues which cannot be addressed within the DT • Notes • A drafting team is not expected to develop new specifications • Implementing rules should be based on standards (when exist)

  6. Objectives of the Drafting team (2) Objective of the Network services drafting team • Draft Implementing rules for INSPIRE network services • Scope • Define functional and non-functional requirements to support the following functionalities:

  7. Objectives of the Drafting team (3) • Network services must be accessible through a EU geo-portal Therefore the geo-portal software architecture shall enforce the inter-operability with the Member States network. In particular the following issues will be addressed: • General architectural model • Security (access to the service and data transfer) when applicable • Multilingualism as requested by INSPIRE. • Metadata for services • Technical architectures and protocols • End-users' needs

  8. Objectives of the Drafting team (3) • Activities • Clarification of definition and scope of INSPIRE Network services • Analysis of reference material • Define interface specifications for INSPIRE network services • Draft Implementing rules

  9. Network services Drafting team members

  10. Planning defined early in 2006 3- Network services Drafting team deliverables

  11. The NS DT is currently working on: Progress and issues (1) • D 3.1: Detailed definition of INSPIRE network services • The clarification of scope and detailed definition have been done for: • A reference model, including “horizontal services”, • Discovery and upload services, • View services • To run this activity, the DT has meetings and JRC supports the DT by organising “state-of-the-art” workshops: • on discovery services (October 2005) • on transformations services and chaining services (April 2006) • on download services (June 2006)

  12. The NS DT is currently working on: Progress and issues (2) • D 3.2: Analysis of reference material from SDICs/LMOs • More than 100 documents and projects relating to network services • A template to help evaluation has been defined • A part of the reference material has been analysed

  13. The current proposal for the INSPIRE Reference Model Reference Model • In the INSPIRE Reference Model, Network services are used by: • The EU Geoportal • INSPIRE Applications • Member states portals and services • The EU Geoportal is composed of 3 layers: • A Horizontal services layer to control access to other services. Horizontal services are: authentication, authorisation, pricing, billing, … • A Portal service layer: the different INSPIRE services • An EU Portal backend layer to store locally data and services • The Reference Model is still in discussion

  14. Reference Model INSPIRE Network Service bus

  15. Reference Model EU Portal as a mediator between member states INSPIRE services and EU level users

  16. Reference Model The conceptual three tier architecture of the EU portal

  17. Reference Model Embedding architecture for INSPIRE Services

  18. Discovery services to search for spatial data setsandspatial data services on the basis of the content of the corresponding metadata and to display the content of the metadata. • As a minimum the following combination of search criteria shall be implemented: • keywords • classification of spatial data and services • spatial data quality and accuracy • degree of conformity with the harmonised specifications • geographical location • conditions applying to the access to and use of spatial data sets and services • the public authorities responsible for spatial data sets and services Discovery services – Upload services (1)

  19. The most relevant specifications for INSPIRE discovery services: • OGC CAT 2.0 with the ISO profile for the Web: CS-W 2.0 ISO AP 19115/19119 • The service metadata will be based on ISO19119 • but not as well developed as ISO19115 is for data metadata • Other application profiles for services? • ebRIM Profil for CS-W? (OGC Draft) • UDDI Profil for CS-W? • Upload services • Possible to view as a link defined in the dataset metadata stored in the catalogue on an remote data repository. When a user wants to upload a dataset, he uses the publish function of the catalogue service. Discovery services – Upload services (2)

  20. The most relevant specification for INSPIRE view services is: • Web Map Service - ISO 19128 • Using the draft CEN TC287 profile of ISO 19128 / WMS 1.3 • Two profiles: 1) general (level 0) and 2) restricted (level1) are defined in the CEN document • There is still discussion in the drafting team about parameters: • WMS version? 1.3 possible? • Output format? PNG, GIF, SVG, WebCGM, … • List of CRS supported? • How to manage the legend? • Availability of metadata of a dataset displayed by a view service? View services

  21. The definition of transformation services has to be clarified • A first instance of transformation services is to operate Spatial Reference System transformations • The most relevant specification for this service is: • OGC WCTS: Web Coordinate Transformation Service (still in draft) • Will need a European SRS Registry • Other transformation services? • Application schema transformation? Transformation services

  22. “Invoke spatial data service” services • “Invoke service” services are understood as the possibility to chain services • Some first remarks: • Geoservices chaining is in an early stage • There is a strong need for SOAP WSDL UDDI for service chaining • There is a need for both CS-W and UDDI • Service orchestration should be described using BPEL (Business Processes Execution Language) • The detailed definition of “invoke service” services has to be refined by the DT

  23. Download services • for downloading datasets • detailed definition will be discussed in June workshop
