Eurostat LOD Pilot – Agile approach POC LOD in Eurostat PoCs Focus LOD architecture PoC 1 – Linking official statistics to improve data dissemination SPARQL endpoint and utility services (query, analytics) Linking to data in the Web of data and other institutions (EC, NSIs) URI strategy Reuse of EC infrastructure Technical architecture Conversion Standards PoC 2 – Publishing metadata as linked open metadata Publishing nomenclatures (such as NUTS) as linked open data Based on SKOS ontology Metadata integration to enhance a data integration Semantic data and metadata queries across physical stores LOD metadata

Eurostat LOD Pilot – First milestones Milestone 1 – Feb 2017 Description of the source data model selected for experimentation (SDMX data and metadata) First version of a target (ontology) data model Mapping between source data models and target data models on selected use cases Specification of URI naming strategy to be adopted for identifying resources Initial version of the prototype environment (deployment of a sample technological stack) Milestone 2 – May 2017 Specification of the approach for data storage (ontology implementation) including documentation of technical (non-functional) aspects (e.g. performance) Initial prototype on sample datasets and selected use cases Revision of target data model Querying samples Document linkage possibilities between Eurostat data and other Linked Open Data sources

ISA2 projet proposal 2018-2021: Improving statistical data and metadata discovery and analysis – to be validated by ISA2 commitee IT Board Meeting ISA2 2016 Work Programme Source Commission Action owner ESTAT (DIGIT, OP) and NSIs Budget 2017: 1000 kEUR Overall: 3400 kEUR Objectives & scope Improve discoverability and use of official statistics data through leveraging the rich European Statistical System (ESS) statistical metadata assets (concepts, codes, nomenclatures …) using semantic technologies Provide policy analysts with enhanced and intuitive officials statistics analytics capabilities Develop key reusable building blocks for querying and integrating cross domains and cross borders statistical data and metadata Major outputs Output desc.
