Open Standards for Linked Organisations (OSLO)

At the crossroads

OSLO - Motivation

3

Impact on the quality and the efficiency of public services

Multiple investments for interlinking data

Authoritative sources exist as independent silo’s

Information is structured/modelled from one perspective

Applications look at the ‘real world’ from different perspectives

OSLO – Raising Interoperability

4

Create OSLO enabled products

Aggregate information from different national, regional and local egovernment

information systems

Create context neutral OSLO semantic models

Develop common standardisation methodology

SHACL Validator - Objectives

7

Adapt and optimise current services and applications

Receive feedback on optimalisations, errors, ...

Check data generated by services or applications against OSLO data standard

Conformance validation

JSON-LD • Has no formal standardized method for data validation

SHACL• Shapes Constraint Language • W3C Recommendation 20 July 2017• A language for validating RDF graphs

against a set of conditions. • expresses all constraints for an application profile,

a REST call often only expose a subset

Examples • Person, Organisation, Address, Public Service, Feedback,

Notification, Consent, Loan, Transactional Service, Road• Examples on GitHub: SHACL - GitHub

With datatype langString

And is defined by dcterms:title

A second attribute “heeftVerantwoordelijke” is specified

With range cv:PublicOrganisation

And is defined by cv:hasCompetentAuthority

> This tool provides a way of validating RDF graphs against the Application Profiles available within the OSLO context. The validation is based on the SHACL Shapes Constraint Language, a language for validating RDF graphs against a set of conditions. SHACL is a W3C recommendation since 20 July 2017.
