1. Validation Architecture in the ESS CSPA Workshop, Geneva 22-24 June 2016 Geneva 22-24 June 2016 Eurostat, Vincent TRONET, Unit B1

2. What does the business architecture for validation do? Defines the to-be state for validation in the ESS Clarifies the respective roles of Eurostat and Member States in the validation of data sent to Eurostat Clarifies how common validation services could be used by Member States and Eurostat 2

3. Current status of the business architecture One of the deliverables of the ESS.VIP Validation was a "Proposal for an ESS Business and IT architecture" Proposal was drafted by Eurostat with limited input from Member States: needs to be finalised with Member States feedback Final goal: Business architecture endorsed by the ESS as the way validation should be performed 3

4. Key principles for validation taken into account in the new business architecture 4 The sooner, the better Well-documented and appropriately communicated validation rules Well-documented and appropriately communicated validation reports Trust but verify (and no correction of data at Eurostat) Rationalized validation process Flexible implementations in countries Clear link between validation and compliance Good enough is the new perfect And other "common sense" principles (KISS, lower burden, step by step approach, …)

5. As-is situation 5

6. To-be situation 6

7. Scenario 1 Member States receive the common rules and implement them in their own validation systems NSI production systems Data to be sent to Eurostat Transmission to Eurostat NSI environment ESS service platform Validation Rule Registry 7

8. Scenario 2 Member States use common ESS services in their process for validation NSI environment ESS service platform NSI production system Data to be sent to Eurostat Transmission to Eurostat Common ESS service Validation Rule Registry 8

9. Scenario 3 Member States use common ESS processes for validation NSI environment ESS service platform Data to be sent to Eurostat Transmission to Eurostat Common ESS service Validation Rule Registry 9

10. Validation in the ESS – IT building blocks 10

11. CSPA service Validation rule manager ESTAT is developing Validation Rule GUI Prototype: – Store VTL rules and rulesets – Graphical User Interface – Service Interface Further IT developments could be performed by Member States (or ESSnets) Interest for scenarios 1, 2 and 3 11

12. CSPA service STRUVAL (Structural Validation) 12 Validates the structure of SDMX compliant data Based on CSPA Used in NAPS-S Web-service UI is being developed Interest for scenarios 2 and 3

13. CSPA service CONVAL (Content Validation) 13 Validation Levels 1+ Will be used in NAPS-S Will be developed according to CSPA ESTAT started the service definition Interest for scenarios 2 and 3 Mostly automatic Expertise also needed

14. High level business process at Eurostat Data validation 14

15. Some challenges 15 Integration of services and link with compliance monitoring High expectancy from stakeholders Weight of current and past situation (inertia an reluctance to change) Lack of resources for a transition phase Diversity and quantity of data providers (close to 500 national organizations) Heterogeneity of current architectures in countries Services to be used mostly by statisticians (not IT experts) Confidential data
