1. Eurostat Services Joint UNECE/Eurostat CSPA workshop Geneva 22-24 June 2016

2. History Production process modelling ESS EA and more specifically SPRA  identification of candidate generic services

3. Eurostat candidate services STRUVAL: SDMX structure validation of files. This is level 0 validation Transformation Service: Transforming data formats, i.e. SDMX 2.0  SDMX 2.1 CONVAL: Validate the data, e.g. the content of the files This is level 1 validation, upper levels under study

4. STRUVAL - now Version 1 is built on top of the SDMX converter validation function It is presented in a simplified interface dedicated to structure validation Uses Oracle Service Bus (OSB) as a proxy/routing system

5. STRUVAL - plans Development team for SDMX tools will split the converter to separate the transformation and the validation parts STRUVAL will then consist of the SDMX Structure Validation service and drop the OSB mediating part A modification in the interface to match this new service will occur.

6. Transformation Service - now Similar to the work on STRUVAL Version 1 is built on top the SDMX converter function It presents a simplified interface dedicated to SDMX transformation Uses OSB as a proxy/routing system

7. Transformation Service - plans Will use the future "SDMX conversion only" service Some other transformations/formats may be considered The service will be the entry point to all transformation, using OSB to call adequate underlying service

8. OSB for STRUVAL & Transformation Version 1 : Oracle Service Bus maps the simple calls to the corresponding complete call to the SDMX converter EC/ESTAT (Intranet) 3 rd parties Client Application Server SDMX Converter Service Service Bus Service Mediation HTTP(S) SOAP Client HTTP(S) SOAP STRUVAL Transformation

9. CONVAL - plans Version 1 will provide level 1 content validation (intra-file data validation) Version 1 will be based on EDIT which is used by several countries for validation in the European Statistical System (ESS)EDIT Version 1 should be ex-DEV in Summer 2016 Further plan is to integrate VTL as part of version 2 of CONVAL

10. Other services ? Existing services developed by Eurostat could also be adapted to be offered as CSPA services. SDMX tools would be good candidates (registry, RI…)

11. Eurostat’s services goal Every service making sense to share will be developed as loosely coupled as possible (sharing + reuse) These services will be put in the Service Catalogue under EUPL (free, OSS) In the process, participate in CSPA’s evolution (more specifically building the CSPA LIM where needed)

12. Eurostat Service orchestration Benefit of the Service Oriented Architecture : service orchestration Activiti is the open source component chosen for the orchestration via workflows (same component chosen for the future catalogue workflow)Activiti Workflow in place for National Accounts Oracle Service Bus kept for service proxy towards external world due to IT services constraints
