5-star deployment scheme by Tim Berners-Lee

6. Reminder : key benefits of using Linked data approaches (based on RDF standards)
The statistical data and metadata, become (web) addressable. This allows publishers and third parties to annotate and link to this data/metadata.
Data can be flexibly combined across datasets sets. The statistical data becomes an integral part of the broader web of linked data.
Publishing as linked-data offers a flexible, non-proprietary, machine programmable means for providing advanced and dynamic querying and visualisation capabilities

7. Joint framework for action (DIME- Feb 2017)

8. Joint framework for action and roadmap
Development of a proposal for a reference architecture for LOD and for the relevant governance aspects (2017)
Elaboration of joint pilots involving several NSIs, focusing on data and metadata (2018) ESSnet
Development of a community of practice for all NSIs investing in LOD or wishing to learn- (2018) ESSnet
Engagement with users and stakeholders
Training and knowledge sharing
Guidance on how to design and build an LOD portal
Implementation of standards
Toolkit: evaluation of existing tools, selection of a standard set of tools, recommendations performance optimisation

9. ESS LOD reference architecture

10. ESS LOD Reference Architecture
Capability definitions
Relevant standards
Building blocks
High level Application Architecture
LOD principles
Template for Use cases

11. ESS LOD Reference Architecture
Draft document for review and discussion with ESSnet LOD pilots/ESS EAB
Aims to provide a template for statistical organisations in the development of their own LOD capabilities and infrastructure
It does not have a binding character but help to spread common views and definitions and to foster collaboration between partners.
Basis for ESS LOD strategy and mapping for ESS developments

12. Eurostat LOD pilot

13. Eurostat LOD pilots Mirror of ESSnet activities
Cross domains, cross institutions data sets exposed as linked data together with metadata
Permanent URI for NUTS3 published
Explore and evaluate data discoverability,data integration, data visualisation/analytics capabilities offered by the technology
Building internal capabilities and demonstrate business benefits
Identify existing infrastructures and reusable component at EC level

14. Related initiative
ISA2 project proposal

15. Eurostat project proposal for the 2018 EC ISA2 program: Enhancing statistical data and metadata discoverability and analytics capabilities for users (policy DG's, external researchers, data scientist, ….)

16. 2018 : Studies and POC 2019 -2020 (to be confirmed):
Architecture definition (business, information, application, security), including semantic aspects
PoC using confidential data and "confidentiality on the fly" (table builder)
(to be confirmed):
Reference ontology
Semantic repository exposing metadata assets (nomenclatures, …)
Basic services (UI, metadata management, …) -> successors of RAMON
Advanced services : confidentiality on the fly, semantic query and data analytics

17. DIME & ITDG Discussions
Any development regarding LOD in MSs (national policies, infrastructure)
How to ensure synergies between ISA2 project and other international and national initiatives
Are the existing governance arrangements (comprising the Steering Group, Work Package team and ESSnet and in the framework of DIGICOM and the ESS Enterprise Architecture Board) sufficient for LOD?
