Project ESS.VIP.SERV:
Sharing common functionalities
in the ESS
ESS CSPA basecamp

7. ESS.VIP.SERV Objectives
The purpose of the project is to:
Implement governance structure to enable sharing of services
Contribute to standardising the description of business needs by providing CSPA compliant guidelines for describing service definitions
Host and maintain a CSPA service catalogue at the Commission/Eurostat containing also services identified at ESS level
Provide guidelines and recommendations for the ESS enabling national projects to realize technological solutions for industrialisation and integration of processes and for the rationalisation of information systems.
Provide an ESS/Eurostat SOA environment for sharing services in the ESS for which no replication is necessary.
Provide Proof of Concepts statistical services that are re-used in various organizations

8. ESS.VIP.SERV Benefits
Easier exchange of information about re-usable statistical services
Flexible business processes
Faster adoption of new production processes
Cost reduction of development and maintenance of information systems
Easier management of skills

Coordination with Business Projects
Provide guidance for business projects to deliver results in line with SERV
CSPA Catal.

10. Implementation – Services in Business Projects
Cooperation with ESS.VIPs:
Validation – STRUVAL services
ESBRS – Unique Identification service
Cooperation among projects is the key

11. Start of the TF and ESSnet will bring the project to next gear.
Project Status
Deliverables already provided:
Hosting of the CSPA Service Catalogue
SOA Infrastructure for hosting services available
Deliverables provided in the next 2 months:
Structured validation service and NAPS-S POC
Evaluation and start of ESSNet
Project Reviews will follow:
Jan 2016: By VIG
May 2016: By ESSC
Start of the TF and ESSnet will bring the project to next gear.

12. SOA Infrastructure MIDDLEWARE
3rd parties
EC/ESTAT (Intranet)
Service Bus
Service Mediation
Application Server
Service implementation(s)
Client
Manages service interfacing
Decouples/Abstracts the service interface from its implementation
Manages 'light integration' -> protocol transformation (eg : HTTP -> JMS)
Service throttling
SLA management at runtime, audit trailing capabilities

13. Project Governance Project reports to VIG
TF SERV is an integral part of the project
Steering Group will be established soon:
Core group – main involvement
Wider group – for information

14. ESSnet Sharing Services in ESS
From 2016 to 2017
Work packages:
ESS guidelines and procedures
Plan for a Centre of Excellence for sharing statistical services in ESS
Apply services – provide real-life examples of re-use and integration of statistical services
Identification of re-usable services and analysis of requirements
Fostering open source solutions for statistical services

15. Annex / Backup slides

16. Main page

17. Service description Follows the SERV service guidelines
Split in three layers
Service Definition
Service specification
Service implementation
Entries must only have the "Service definition" part filled in

18. Service Definition

19. Service Specification

20. Service implementation (1/3)

21. Service implementation (2/3)

22. Service implementation (3/3)

23. Roles & Rights Catalogue is ECAS protected
Main roles: users, editors, moderators
Service owners are responsible to restrict access to their service descriptions

24. Discussion platform
Comments are allowed on Definition, Specification and Implementation level
Allows discussion between stakeholders
Aims to get best out of the services before going towards the ral implementation

25. Limitations Not directly accessible, ECAS account is needed
MediaWiki page has been created (freely accessible, but static content)
Wiki based:
no real databases for storage
templates based
labels driven
difficult to implement business logic or cross connections

26. MediaWiki page
Why? To have an authentication free entry point First place in Google result for search term "CSPACatalogue"
Content:
High level description of the CSPA project
List of services included in the full catalogue
Instruction to get access to the full catalogue
