Research 

Institutional aspect: Cadastral systems / land administration, real estate valuation and taxation, land re-adjustment, land consolidation, and expropriation.
Technological aspect: Spatial data infrastructure, geographic information standards, data modeling, knowledge organization systems, semantic web, and linked data.

Core Immovable Property Vocabulary

The Core Immovable Property Vocabulary (version 1.0), as an extension to the e-Government Core Vocabularies (version 1.0) is a Resource Description Framework Schema (RDF Schema) for the publication of core information recorded at land administration registries (i.e. cadastre, land registry, building and dwelling registry, address registry, and property tax registry) with the Linked Data approach. It provides a common data model that  identifies the recording units of land administration registries and their core attributes, as well as relationships between them. The Core Immovable Property Vocabulary was developed by simplifying and capturing minimal characteristics of complex domain standards and data specifications, e.g. ISO 19152:2012 Land Administration Domain Model, OGC 12-019:2012 CityGML, and related INSPIRE data specifications. It allows for the publication of land administration datasets within the Resource Description Framework (RDF), and renders the integration of land administration datasets with other registries such as address and civil registries encoded according to the e-Government Core Vocabularies. For more information see: https://joinup.ec.europa.eu/asset/cipv/description.

Cadastre and Land Administration Thesaurus  CaLAThe

The Cadastre and Land Administration Thesaurus (version 2.0), shortly CaLAThe  is a Knowledge Organization System for the domain of cadastre and land administrationIt provides a controlled vocabulary, which is derived mainly from the ISO 19152:2012 Land Administration Domain Model and related to existing thesauri, primarily the GEMET thesaurus, the  AGROVOC thesaurus, and the STW Thesaurus for Economics. The main purpose is to create a semantic model which may improve organization of knowledge, e.g. in terms of a formal ontology of the domain. The CaLAThe is encoded as a Simple Knowledge Organization System (SKOS), according to specifications developed by the World Wide Web Consortium (W3C). For more information see: cadastralvocabulary.org.
