The European Data Portal (EDP) beta version was launched on November 2015. Since then, a new version of the website has been released several times a year with the latest being on 2 May 2019, when the EDP launched version 2.3 of the website.
Previous enhancements and extensions of the EDP website included:
- the development of an API for editorial content (e.g. the EDP use cases, news items and events),
- harvesting of additional catalogues from geo- and non-geo sources,
- a focus on linked metadata (interlinking metadata sets),
- enhancing graphical data visualisations and the geo-spatial visualisation services such as city level base maps that are provided by Eurostat, and
- enhancements of the MQA with the use of W3C Data Quality Vocabulary (DQV), introducing a scoring metric and enhancing catalogue reports.
EDP version 2.3
The EDP version 2.3 includes several new features - features that are visible and hidden from end-users. The new features for version 2.3 include:
- Implementing a fully DCAT-AP native metadata catalogue that makes it easier for users to search for data;
- Going beyond the limitations of CKAN - an open source data portal software that acts as a data management system and makes data accessible by providing tools to streamline publishing, sharing, finding, and using data;
- Drastically improving performance on all metadata related components, such as metadata catalogue and Metadata Quality Assurance (MQA) - a monitoring tool for metadata quality;
- Ensuring that MQA uses SHACL - a World Wide Web Consortium (W3C) specification for validating graph-based data against a set of conditions - validation for DCAT-AP compliance tests;
- Implementing a SPARQL-Manager that supports asynchronous queries and notifies users via mail if a query has been completed;
- A complete re-design of the catalogue statistics page; and
- Implementing a data storage so that datasets can be discoverable on the EDP, and data can be stored (this will be useful for example for European Union agencies or EU-funded projects that need to start quickly publishing their data and that need more time to setup their own website.
