Explore the application of dynamic transfer modelling using the "Mushroom Model" to understand how property rights change over time. This study delves into the complexities of modelling rights within the Core Cadastral Domain Model, emphasizing the importance of considering subjects, rights, and objects together. Learn how to create general models to comprehend the transfer of rights instead of detailing every aspect.

Transfer modelling • Hans Mattsson, Riga October 2004 • Modelling • Core Cadastral Domain Model = static (Lemmon, COST etc.) • Activity diagrams = dynamic (Sumrada, COST etc.) • “Mushroom model” = dynamic (Zevenbergen) • Current situation • Static models do not show in what way rights are changed • Activity diagrams do not show in what way rights are changed • “Mushroom model” can be a starting point for modelling?

Core entities model Ex. Sale S1 S (subject related to the right/person) S2 R (ownership right) R Object (object for the right/land) O 1. See also Zevenbergen, 2001, 2004 2. ULM terminology is not used in the presentation.
Subdivision (assumption: no localized rights or restrictions) What happens on the land? Original property Remaining property New property What happens on the person, right and object? Original property before decision Properties after decision S1 S1 S1 + R R RNew O ORemaining ONew
Reallotment (assumption: no localized rights or restrictions) What happens on the land? Property 1 (before) Property 2 (before) Property 1 (after) Property 2 (after) Part Part What happens on the person, right and object? Before decision After decision S1 S2 S1 S2 + + R1 R2 R1 R2 O1 O2 O1+part O1-part
Lease (new lease is contracted for the whole property) What happens on the land? Original property used by the owner Original property used by leaseholder What happens on the person, right and object? Original property before lease Property with lease S S LH R R-Lease right + Lease right O O O
HM hypotheses for “mushroom” modelling: • Dynamic transfer modelling must include rights • Subjects, rights and objects must often be considered together • Rights are more difficult to model than subjects and objects • People modelling rights must be good in modelling and law • Models shall be general and not covering everything • The goal is to understand, not to show everything
