Administrative burden

Costs borne by individuals and businesses in order to comply with information obligations resulting from Government regulation or associated with obtaining specific services or exploiting a functionality.

Indirectly, this includes the costs to public administrations of dealing with multiple procedures, data and information concerning the same subject, ultimately paid by individuals and businesses.

Authoritative source

An authoritative source is information that is stored only once and which is believed to be correct, so can serve as a basis for further processing.

Base Registry / Register

A Base Registry is identified as being a trusted and authoritative source of information which can and should be digitally reused by others and in which one organisation is responsible and accountable for the collection, usage, updating and preservation of information. Base registries are reliable sources of basic information on items such as persons, companies, vehicles, licences, buildings, locations and roads.

This type of information constitutes the master data for public administration and European Public Service delivery. "Authoritative" in this context means that a Base Registry is considered to be the source of information i.e. which represents the correct status, which is up-to-date and which is of highest possible quality.

Blockchain

A blockchain is a distributed database that keeps a continuously-growing list of records protected from revision and tampering. Basically, the blockchain technology is a public ledger that records all transactions that have ever occurred.

The official blockchain public site lets any person to get these transactions in real time and evaluate the basic stats of the system, such as the time between blocks, a number of blocks made, mining costs, the cost per transaction and most fascinatingly even the electricity used to mine bitcoins.

Cross-border by default

Cross-border by default is one of the seven underlying principles of the EU eGovernment Action Plan 2016-2020. It means that public administrations should make relevant digital public services available across borders and prevent further fragmentation to arise, thereby facilitating mobility within the Single Market.

Cross-border processing

The General Data Protection Regulation (GDPR) definition illustrates its difference from the general meaning of further processing in conjunction with OOP at European level (which typically involves multiple data controllers and data subjects in more than one Member State):

(a) processing of personal data which takes place in the context of the activities of establishments in more than one Member State of a controller or processor in the Union where the controller or processor is established in more than one Member State; or

(b) processing of personal data which takes place in the context of the activities of a single establishment of a controller or processor in the Union but which substantially affects or is likely to substantially affect data subjects in more than one Member State.

Source: Final Report "EU-wide digital Once-Only Principle for citizens and businesses"

Data controller

From Art. 4(1) of the General Data Protection Regulation (GDPR): The natural or legal person, public authority, agency or other body which, alone or jointly with others, determines the purposes and means of the processing of personal data; where the purposes and means of such processing are determined by Union or Member State law, the controller or the specific criteria for its nomination may be provided for by Union or Member State law.

The European Data Protection Supervisor defines it as: The institution or body that (either alone or jointly or in common with other persons) determines the purposes and means of the processing of personal data. In particular, the controller has the duties of ensuring the quality of data and, in the case of the EU institutions and bodies, of notifying the processing operation to the data protection officer (DPO). In addition, the data controller is also responsible for the security measures protecting the data. The controller is also the entity that receives requests from data referents to exercise their rights.

Data model

A data model is a collection of entities, their properties and the relationships among them, which aims at formally representing a domain, a concept or a real-world thing. It includes core vocabularies.

Data ownership

Under EU law, personal data may not be owned. For other types of data, the following definition may be useful:

“The act of having legal rights and complete control over a single piece or set of data elements. It defines and provides information about the rightful owner of data assets and the acquisition, use and distribution policy implemented by the data owner.

Data ownership is primarily a data governance process that details an organisation's legal ownership of enterprise-wide data. A specific organisation or the data owner has the ability to create, edit, modify, share and restrict access to the data. Data ownership also defines the data owner’s ability to assign, share or surrender all of these privileges to a third party. This concept is generally implemented in medium to large enterprises with huge repositories of centralised or distributed data elements. The data owner claims the possession and copyrights to such data to ensure their control and ability to take legal action if their ownership is illegitimately breached by an internal or external entity.”

Data processing

Any operation or set of operations which is performed upon personal data, whether or not by automatic means, such as collection, recording, organisation, storage, adaptation or alteration, retrieval, consultation, use, disclosure by transmission, dissemination or otherwise making available, alignment or combination, blocking, erasure or destruction.

In particular, includes:

  1. organisation, adaptation or alteration of the information or data,
  2. retrieval, consultation or use of the information or data,
  3. disclosure of the information or data by transmission, dissemination or otherwise making available, or
  4. alignment, combination, blocking, erasure or destruction of the information or data.

Digital by default

Digital by default is one of the seven underlying principles of the EU eGovernment Action Plan 2016-2020. It means that public administrations should deliver services digitally (including machine readable information) as the preferred option (while still keeping other channels open for those who are disconnected by choice or necessity). In addition, public services should be delivered through a single contact point or a one-stop-shop and via different channels.

Digital Single Market Strategy for Europe

The vision of a Digital Single Market Strategy for Europe is defined by fewer barriers, and more opportunities: it is a seamless area where people and business can trade, innovate and interact legally, safely, securely, and at an affordable cost, making their lives easier. The Digital Single Market Strategy will be built on three pillars:

  • Better access for consumers and businesses to online goods and services across Europe – this requires the rapid removal of key differences between the online and offline worlds to break down barriers to cross-border online activity.
  • Creating the right conditions for digital networks and services to flourish – this requires high-speed, secure and trustworthy infrastructures and content services, supported by the right regulatory conditions for innovation, investment, fair competition and a level playing field.
  • Maximising the growth potential of our European Digital Economy – this requires investment in ICT infrastructures and technologies such as Cloud computing and Big Data, and research and innovation to boost industrial competitiveness as well as better public services, inclusiveness and skills.

e-SENS

The project Electronic Simple European Networked Services (e-SENS) is to facilitate the deployment of cross-border digital public services through generic and re-usable technical components, based on the building blocks of the Large Scale Pilots.

The consolidated technical solutions, with a strong focus on e-ID, e-Documents, e-Delivery, Semantics and e-Signatures, aim to provide the foundation for a platform of “core services” for the eGovernment cross-border digital infrastructure foreseen in the regulation for implementing the Connecting Europe Facility (CEF).

These solutions are implemented in pilot production environments where actual transactions among public administrative bodies, or between them and European citizens and businesses, can take place. This is expected to unlock the potential of cross-border services and strengthen the functioning of the Digital Single Market in Europe.

European eGovernment Action Plan 2016-2020

The digital transformation of government is a key element to the success of the Single Market. It will help to remove existing digital barriers and prevent further fragmentation arising in the context of the modernisation of public administrations.

Therefore, the European eGovernment Action Plan 2016-2020 aims:

  • to modernise public administration,
  • to achieve the digital internal market, and
  • to engage more with citizens and businesses to deliver high quality services.

The European eGovernment Action Plan 2016-2020 will support the coordination and collaboration at European Union level. Through the joint efforts between Member States and the Commission, the availability and take-up of eGovernment services can be increased, resulting in faster, cheaper and more user-oriented digital public services.

Loose coupling

Loose coupling refers to communications between systems that operate more or less independently of one another (asynchronously) and whose internal states are not strongly interdependent.

The coupling takes the form of messages passed between the systems in question, typically implemented using some type of middleware layer or queuing system, so that the target system deals with requests as and when it can. Thus, the target system may not even be available at the time of the request, which is simply queued for later action.

Whole-Government Principle

The principle that persons and businesses interacting with a government entity are interacting with the whole of the national government. This principle is complementary to the OOP, but differs in that it is not limited to – and does not directly imply – data re-use. It includes:

  • The one-stop-shop principle – that individuals or businesses should not need to know how public administrations work or how competencies are allocated across state agencies but should instead be able to deal with a “single-window” representing public administration as a whole. At EU level, these are called Points of Single Contact (PSCs);
  • The “no wrong door” principle that there should be multiple channels for access to public services.
