Digital Object Identifier, an identifier for a digital object (such as a document or dataset) that is assigned by a central registry and is therefore guaranteed to be a globally unique identifier: no two digital objects in the world will have the same DOI.

It is not enough for open data to be published if potential users cannot find it, or even do not know that it exists. Rather than simply publishing data haphazardly on websites, governments and other large data publishers can help make their datasets discoverable by indexing them in catalogues or data portals.


An ordinary table or spreadsheet can easily represent two data dimensions: each data point has a row and a column. Plenty of real-world data has more dimensions, however: for example, a dataset of Earth surface temperature varying with position and time (two co-ordinates are required to specify the position on earth, e.g. latitude and longitude, and one to specify the time).


The Digital Europa Thesaurus (DET) is a multilingual thesaurus covering the main subject matters of the European Commission's public communications.


A form of anonymisation where personal records are kept intact but specific identifying information, such as names, are replaced with anonymous identifiers. Compared to aggregation, de-identification carries a greater risk of data leakage: for example, if prison records include a prisoner’s criminal record and medical history, the prisoner could in many cases be identified even without their name by their criminal record, giving unauthorised access to their medical history.

Deep Learning

Deep learning is a form of machine learning that enables computers to learn from experience and understand the world in terms of a hierarchy of concepts by using multiple layers to progressively extract higher level features from the raw input. Because the computer gathers knowledge from experience, there is no need for a human computer operator formally to specify knowledge needed by the computer.


DCAT application profile. A common vocabulary for describing datasets hosted in data portals in Europe, based on the DCAT.


Data catalogue vocabulary. RDF vocabulary for interoperability of data catalogues.


A collection of related sets of data that is composed of separate elements but that can be manipulated as a unit and accessed or downloaded in one or more formats. Source: EU OD
