Open Data - Why open standards and Mid-Office integration are important

Open standards are stable, published formats for data and services that are independent of any individual supplier. They are essential for systems and data to be interoperable. Without open standards, open data can realise only a fraction of its value.

Local governments in Flanders believes that interoptability at the level of the the mid-office and an information policy are the key to adoption of the open data philosophy by the local governments.  Open Government Data Standards will allow data to be Complete, Primary and Timely.


  • Complete. All public data is made available. Public data is data that is not subject to valid privacy, security, or privilege limitations.
  • Primary. Data is collected as close as possible to the sources, with the highest possible level of granularity.
  • Timely. Data is made available as quickly as necessary to preserve the value of the data.


Why is the OSLO standard needed?

Open data standards and architecture are needed to drive integration with back office systems


Often, 'Smart Cities' are frustrated by: (1) a lack of open standards for (local) government data and (2) the vertical and cumbersome structure of their data architectures.  ISA core public services ( ISA – the Interoperability Solutions for European Public Administrations programme) and W3C  Government Linked Data (GLD) Working Group has provided standards and other information to help governments around the world publish their data as effective and usable Linked Data, using Semantic Web technologies. However, there is a large gap to fill to bring local governments up to the standard required to achieve their objectives in publishing and exploiting open, linked data. The maturity of city with respect to open data often has a direct correlation with its adoption of open standards and the principles of open architectures. The integration of back-office systems with open data will lower the barriers to opening up opportunities for local administrations to use the feedback from those exploiting the data they publish. 

What is the vision of the OSLO Public Service standard? 

OSLO aims to offer a technology independent, generic representation of a service provided by public administrations in Flanders. The vocabulary will emerge as an interface between existing national, regional and local public service models, providing a lingua franca that will enable the seamless exchange of services and information across different e-Government systems in local communities. 

This will allow local communities to interconnect business registers and back-office applications  using the OSLO Core Vocabulary. OSLO will will describe the core business objects using RDF[1] specifications (Person, Organization, Lokalisation and Public Service Ontology).

The first three Core Vocabularies have been developed by have been undertaken by the Government Linked Data Working Group (GLD WG, where V-ICT-OR is a member) of W3C and ISA (European Commission). The CORE Public Service Ontology is being developed by ISA (V-ICT-OR is a member of the workgroup). OSLO will adopt the best practices of ISA and will be an extention of the ISA CORE vocabularity (the Interoperability Solutions for European Public Administrations programme).

impression of the OSLO model (working draft)

[1] The Resource Description Framework (RDF) is a family of World Wide Web Consortium (W3C) specifications [1] originally designed as a metadata data model. It has come to be used as a general method for conceptual description or modeling of information that is implemented in web resources, using a variety of syntax formats.
