Initiating the development of a LADM II-based Country Profile for the Swedish Real Property Register RRR

The Swedish real property register, administered primarily by the Swedish Mapping,<br/>Cadastral and Land Registration Authority (Lantmäteriet), has a long history of providing<br/>reliable and comprehensive land records. There is a growing need for improved<br/>interoperability and data sharing among different stakeholders, integration of 3D spatial data,<br/>and addressing the legal and institutional barriers to further digitization. The Land<br/>Administration Domain Model (LADM) provides a standardised framework for modelling<br/>land administration systems worldwide, defined and developed as an international standard<br/>ISO 19152:2012 (ISO, 2012). Given the promising research of LADM-based country profiles<br/>by academics and authorities in other countries, we start developing a Swedish LADM-based<br/>country profile.<br/>The main purpose of this paper is to initiate the development of a Swedish LADM II-based<br/>country profile for a part of the content of the Real Property Register. This study will use the<br/>three-phase methodology that has been presented by Kalogianni et al. (2021), and then focus<br/>on the Phase I to analyse current Swedish land administration and its RRRs. As the initiation<br/>step, this paper will not implement a full LADM II-based Swedish country profile, mainly<br/>focusing on the administrative aspects.<br/>The paper presents the research methodology to initiate the development of a Swedish LADM<br/>II-based country profile, and then introduces the Swedish real property register and its<br/>content, focusing on registered RRRs. The Swedish LADM model presented in this paper is<br/>only illustrative and discusses the complexity of Swedish RRRs as an early step in producing<br/>a national Swedish model, since the legal basis for the future content and structure of the<br/>register is yet unsure. For the future work, the core LADM classes will be customized to<br/>reflect the specific requirements of the Swedish context, and relationships and associations<br/>between the classes will be established to accurately represent the interactions and<br/>dependencies within the Swedish land administration system.
