Specialization of the Land Administration Domain Model (LADM): Modelling on non-formal RRR

This paper proposes a more detailed classification of the legal part of the LADM, ISO 19152, (i.e. interests in land) than possible in the current standard (ISO, 2012) today and is an attempt to raise awareness of the possibilities to further develop the LADMs ‘right’, ‘restriction’ and ‘responsibility’ classes (RRR). The term ‘land’ is here used for land, water and air. The LADM does, in principle, already facilitate the modelling of e.g. informal and customary rights. However, there has, to the authors’ knowledge, not yet been any approach that incorporates non formal social tenure relationships, such as informal occupation, tenancy based on non-formal and informal rights and customary rights into the LADM. This paper uses the non-formal rights descriptions in the Social Tenure Domain Model (STDM) as an input to further develop the LADM. In this paper the authors base their research on an extended classification of the LADMs RRR classes presented at the FIG Working Week in Nigeria (Paasch et al., 2013). The extension is based on the newly developed Legal Cadastral Domain Model, LCDM (Paasch, 2012a), as a conceptual basis for adding an additional level to the LADM classification. The LCDM states that interests in land can be classified according to whether they are limiting or beneficial to real property ownership. The extended classification is further based on the paradigm that there are two major types of interest in land, privately agreed interests and regulations imposed by a public agency to further the interests of society. This paper contains a discussion on how the legal part of the LADM can be expanded. Furthermore, the “code list” issue addressed in the FIG 2013 Working Week paper is further researched in this paper, e.g. how to develop the code lists for refined LCDM classes (based on specialisations), that could/should be used. The incorporation of a specialized description of non-formal rights in the LADM may be of future value when (if) more detailed information on social tenure land use has to be stored in national or international land administration registers. The LADM allows national specializations to be added to the standard, however, such specializations may be useful when used within a nation, but are of rather limited value when more detailed data of interests in land has to be exchanged internationally. This would require international maintenance of code tables.OTB ResearchOTB Research Institute for the Built Environmen

Specialization of the Land Administration Domain Model (LADM): An Option for Expanding the Legal Profiles

The Land Administration Domain Model, LADM, passed on the 1st of November 2012 unanimously the final vote towards becoming an international standard, ISO 19152. Based on the standard this paper is a proposal for a more detailed classification of interests in land as modelled within LADM and an attempt to raise the awareness of the possibilities to further develop the LADM?s “right”, “restriction” and “responsibility” (RRR) classes. The current standardised classification of RRRs in the LADM is restricted to a top-level classification of RRRs. In this paper the authors use the classification of interests in land described in the newly developed Legal Cadastral Domain Model, LCDM, to further develop the LADM. The LDM is based on comparative international legal investigations, including case studies from Portugal, Germany, the Netherlands, Ireland and Sweden. The conceptual basis of the LCDM is that interests in land can be classified according to whether they are limiting or beneficial to real property ownership. The classification in the model is further based on the paradigm that there are two major types of interest in land; privately agreed interests and public regulations imposed by a public agency to further the interests of society. This is a pattern that can be observed in the legislation of many different jurisdictions, and therefore a useful extension of the international standard. The result of the paper is a proposal on how the administrative part of the LADM (i.e. interests in land) can be expanded. This work can be used to improve and extend the current informative LADM Annexes F \u84Legal Profiles? and J \u84Code lists?. Customary and informal rights have not been investigated in the LCDM, but can already be represented in the LADM (and its extension STDM: Social Tenure Domain Model). Inclusion of further options for representation of detailed attributes might be very useful for a next LADM version. The possible extension of LADM does not bring any limitation to the use and implementation of LADM – which is already on-going in several countries. On the contrary: the flexibility of LADM as a concept is demonstrated again and the proposed extensions may be very useful for those countries where a more detailed classification of RRR is under discussion.OTB ResaerchOTB Research Institute for the Built Environmen
