A Data Publication Component is an architectural building block of the EIRA Technical view - infrastructure supporting the Technical interoperability layer of the European Interoperability Framework.
It is included in the Enabler grouping Infrastructure Data Source Enablers.

Data Publication Component is a specialisation of Application Component that provides Data Publication Service . It implements the functionality of making data available for common use.

The Data Publication Component ABB  is salient for technical interoperability because it provides the implementation of the functionalities to make public data freely available for use and reuse by others unless restriction aoply as stated in the EIF recommendation #eif02 - Publish the data you own as open data unless restrictions apply: "Publish the data you own as open data unless certain restrictions apply."


The following implementations is an example on how this specific Architecture Building Block (ABB) can be instantiated as a Solution Building Block (SBB).

CKAN is the world’s leading Open Source data portal platform system that makes data accessible by providing tools to streamline publishing, sharing, finding and using data. This is a tool for making open data websites. It helps you manage and publish collections of data. It is used by national and local governments, research institutions, and other organizations who collect a lot of data.

Once your data is published, users can use its faceted search features to browse and find the data they need, and preview it using maps, graphs and tables – whether they are developers, journalists, researchers, NGOs, citizens, or even your own staff.
CKAN is open source and free software, with an active community of contributors who develop and maintain its core technology. CKAN is modified and extended by an even larger community of developers who contribute to a growing library of CKAN extensions.

The latest release of the EIRA© is available on Joinup.
