EuroVoc is a multilingual, multidisciplinary thesaurus covering the activities of the EU, the European Parliament in particular.

European Data portal

An open data portal which displays data from the EU member states national open data portals, as well as the portals of the EEA countries and some candidate and neighbouring countries. It should not be confused with the EU open data portal which contains datasets from the EU institutions, agencies and services.

EU PSI Directive

The Directive on the re-use of public sector information, 2003/98/EC, amended by 2013/37/EU is the first EU legislation on the reuse of public sector information which established a requirement to ensure that public sector publishes its open data in machine readable format, and that it handles the requests of users, with a possibility of a redress before an independent authori

EU Open Data Directive

The Directive on open data and the re-use of public sector information 2019/1024/EU is a recent legislative piece on open data which replaces the former PSI Directive of 2003 and 2013. The Directive included the term ‘open data’ in its title, and broadened the scope of application onto public enterprises. It introduced the concept of high-value datasets, insisting on the use of APIs and dynamic data.

Error Response Code

Errors are an inevitable part of API integration, and providing not only a robust set of clear and meaningful API error response codes, but a clear listing of these codes for developers to follow and learn from is essential.


An association between a binding and a network address, specified by a URI, that may be used to communicate with an instance of a service. An end point indicates a specific location for accessing a service using a specific protocol and data format.

ELI (European legislation identifier)

European legislation identifier, allowing to uniquely identify and access national and European legislation online and to guarantee easier access, exchange and reuse of legislation for public authorities, professional users, academics and citizens. ELI paves the way for a semantic web of legal gazettes and official journals. 

Dynamic data

Documents in digital form, subject to frequent or real-time updates, in particular because of their volatility or rapid obsolescence. Data generated by sensors are typically considered to be dynamic data.

Source: OD Directive.

Document Type Definition

In a broader sense, it is a set of rules that defines a grammar for a class of documents, namely SGML-based documents (XML, HTML, …), thus being important for interoperability and data exchange. DTD specification, being an older format lacking important functionalities, is in general superseded by the newer XML Schema format.
