Release Notes

In September 2014, the ISA Programme of the European Commission released version 1.1 of the Core Vocabularies. This version contains consolidated and updated versions of the: Download the current release of the Core Vocabularies using the download buttons in the "distributions" section below. The spreadsheet files (xslx and ods) are the normative releases.

Updated definitions, descriptions, and examples

Crisp, one-line definitions were added for every class, property, and association. The definitions are in line with the original descriptions, i.e., they do not change the semantics of the elements. In most cases, the definitions are short rewordings of the original descriptions.
Descriptions, providing additional information to the definitions, were updated. In particular, the recommendation to use DBPedia URIs for identifying countries has been replaced by the recommendation to use the Named Authority Lists (NALs) of the Publications Office of the EU.
Examples were extracted from the descriptions and are now shown in a separate column. The examples were updated to reflect the new recommendation to use the NAL for countries.

Consolidated naming conventions

The names of classes, properties, associations, data types, and attributes are now all space-separated and title-cased, i.e., every word starts with a capital letter. A unique identifier is automatically derived from the name by removing any space. Simple nouns are preferred for property names. For example, “hasChannel” has been renamed to “Channel”. Furthermore, the RDF namespaces that are used in the CPSV model are removed. For example, “foaf:Agent” has been renamed to “Agent”.

Updated data types

We make the distinction between primitive types (consisting of singular values) and composite types (composed of multiple attributes). For example, we now distinguish between the String data type, which is a simple sequence of characters, and the Text data type, which is a string combined with a language identifier.

Removed cardinalities

In order to maximise reusability in this Core Vocabulary, all cardinality constraints have been removed. This only affects the Core Business Vocabulary that restricted some properties of the Legal Entity class.

Removed generic properties

The specification of the Core Vocabularies 1.00 defined the following properties without any domain restriction: Because such generic properties provide no additional information to mappings, we have not included them in their generic form in the spreadsheet. Instead, the properties are applied to some classes, where it makes sense. The mappings of such properties are more meaningful. The following properties were added: The generic Legal Entity property was not applied to any class.

Removed undefined classes

The undefined “License” and “Change” classes have been removed. Such classes were included in the specifications as recommendations for further work. The removal is safe because neither the classes nor the envisioned “change” and “holdsLicence” relationships were implemented in the technical representations.

Single conceptual Geometry class

The previous UML models of the Core Vocabularies 1.00 contained two representations for the Geometry class, leading to confusion. The conceptual description of the Geometry class in the specification text corresponds to the alternative representation. Only that class was kept. Copyright © 2012 European Union.
