1 Transfer modelling Hans Mattsson, Riga October 2004 Modelling 1.Core Cadastral Domain Model = static (Lemmon, COST etc.) 2.Activity diagrams = dynamic (Sumrada, COST etc.) 3.“Mushroom model” = dynamic (Zevenbergen) Current situation 1.Static models do not show in what way rights are changed 2.Activity diagrams do not show in what way rights are changed 3.“Mushroom model” can be a starting point for modelling?

2 Second draft of the Core Cadastral Domain Model Source: Further Progress in the Development of a Core Cadastral Domain Model Christiaan LEMMEN and Peter VAN OOSTEROM, The Netherlands

3 Source: Rados, Ferlan, Mattsson and Vaskovich (forthcoming report, preliminary figure)

4 Mushroom model Source. Zevenbergen, 2004)

5 Core entities model S (subject related to the right/person) R (ownership right) Object (object for the right/land) 1. See also Zevenbergen, 2001, ULM terminology is not used in the presentation. Ex. Sale S1S1 S2S2 R O

6 Subdivision (assumption: no localized rights or restrictions) S1S1 R O Original property before decision S1S1 R S1S1 O Remaining R New O New Properties after decision + Original property Remaining property New property What happens on the land? What happens on the person, right and object?

7 Reallotment (assumption: no localized rights or restrictions) Before decision S1S1 S2S2 O1O1 R2R2 O2O2 After decision + What happens on the land? What happens on the person, right and object? Property 1 (before) Property 1 (after) Property 2 (after) R1R1 S1S1 S2S2 O 1 +part R2R2 + R1R1 O 1 -part Property 2 (before) Part

8 Lease (new lease is contracted for the whole property) S R O Original property before lease SLH O Lease right Property with lease Original property used by the owner What happens on the land? What happens on the person, right and object? O R-Lease right + Original property used by leaseholder

9 HM hypotheses for “mushroom” modelling: 1.Dynamic transfer modelling must include rights 2.Subjects, rights and objects must often be considered together 3.Rights are more difficult to model than subjects and objects 4.People modelling rights must be good in modelling and law 5.Models shall be general and not covering everything 6.The goal is to understand, not to show everything
