Codelists

Codelists (or controlled vocabularies) are meant to organise knowledge that is classifiable in nature. They can be approached from a broad perspective or a more purpose-specific context. These codelsts are used on the properties of the evidence types.

In the context of the semantic web, controlled vocabularies have a double purpose.

• The first purpose involves harmonising concepts to improve technical, business, institutional and inter-institutional communication.
• The second purpose has to do with knowledge management and metadata interchange, and is geared to a machine-readable environment, meant to improve dissemination/discovery, repurposing/reuse, and collection/merging of data across the open and globally connected digital environment of the semantic web.
• There is a third purpose very specific to the EU institutions, which comes from the multilingual nature of the European Union itself. Translation requirements are easily met with the conceptual nature of controlled vocabularies.

Codelist specification (work in progress)

Codelist Name	Description	Link	DE4A Use Case	Remarks
Cause of end of marriage	The cause of end of marriage in the marriage evidence.	TBD	MA UC2
Country	The Country authority table is a controlled vocabulary that lists concepts associated with names of countries and territories. The concepts included are correlated with the ISO 3166 international standard. ISO 3166-1 contains a two-letter code which is recommended as the general purpose code, a three-letter code which has better mnenomic properties and a numeric-3 code which can be useful if script independence of the codes is important. The authority code relies on the ISO 3166-1/alpha-3 positions. If an authority code is needed for a country without assigned ISO code, an alphanumeric code is created in order to not confuse with ISO codes that are strictly alphabetic or numeric.	https://op.europa.eu/en/web/eu-vocabularies/dataset/-/resource?uri=http://publications.europa.eu/resource/dataset/country	MA UC1, MA UC2	To check if we will use alpha-2 or alpha-3
