System's architecture

The architecture of the platform consists mainly in a Data Hub module implemented with CKAN and a Wordpress multi-site front-end. The multi-site front-end is the user's entry point and where the information from both the Wordpress sites and the CKAN data hub is exposed to the user. The CKAN datahub is “hidden” from the end-user and only accessible by staff members for data management purposes.

Data Hub

The Data Hub represents the principal component for storing structured data and metadata on the platform. It should make possible that collaborating organisations from the participating countries upload data, information and other resources in a structured manner. The stored datasets and contents will be then exposed via the Wordpress front-end which pulls this data internally via CKAN's API.

For this module, existing frameworks have been considered to be adopted and building the whole technology solution from scratch discarded. Since using Open Source technologies is a major factor for the selection of the framework to adopt, this research has focused on CKAN (

The Open Data platform developed and maintained by the OKFN and a relatively big community of developers worldwide.CKAN has proven to be a valid platform for using as a base for fulfilling the requirements of the project. In the upcoming paragraphs, key issues will be analysed in detail together with the possible solutions that can be implemented based on the chosen ODP.

Multisite front-end

Wordpress will be the chosen technology for the different regional sites, since most of the partners are already familiar with it and considering that it is an Open Source, community supported and broadly used technology.
