Invitation ... Seminar

1. Introduction

Thanks to the rich contributions to the Kick-off Seminar in Bremen, the research described in the Technical Annex of COST action G9 can now be further specified. The needed research is specified through the following motivation of N sessions, and corresponding calls for papers. The call is to be understood like the calls for the Bremen seminar: Before the Madrid seminar your submit an abstract, implying that you are prepared to develop the issue orally at the seminar, and - taking comments into consideration - prepare a paper for the seminar documentation.

2. Session A: Typifying real property rights

In his Bremen paper: Aspects of Property Rights and its Alteration, Hans Mattsson illustrates how property rights may be typified. Based on the concept bundle of rights, he focuses on attributes of real property rights: Walking, waste disposal, mining, building, gardening, etc. Furthermore, by means of a shematic he illustrates the 'legal processing' of these attributes: Some are prohibited by law, others restricted and/or dependent on permission.

The way of illustrating the attributes, and the formalization criteria in general, calls for comments and discussions. What is evidenced, however, is the need to specify in a systematic fashion activities pertaining to immovables:
Examples Attributes Open access Prohibitions Restrictions Attributes at the owner's disposal Granted 
for use
(5) = 
(1) - (2+3+4) 
(7) = (5+6)
(8) <= (7) 

Contributions for this session may be of two kinds:

  1. A country specific survey of the most important (frequent) factual and legal types of activities, including statutory definitions of key concepts and if possible national doctrine on 'legal processing' regarding immovables.
  2. Suggestions regarding the formalization of property rights and the 'legal processing' of these rights.
The first kind of contribution provides for the empirical evidence, against which the formalization scheme of the second kind of contribution has to be tested.

3. Session B: Comparing processes regarding immovable property

Already before the Bremen seminar, subdivision and to some extent purchase procesess were described for Denmark, Finland, and Slovenia, see at Due to time restrictions, the work was not presented and discussed. Later, a tentative comparison was made for presentation at the FIG International Conference, April 2002, by Erik Stubkjær.

Contributions from other countries, using the UseCase formalism are invited. Tentatively, the following five basic procedures are to be described within the project:

Consequently, the description from the above mentioned countries need supplements.
As in the previous session, the country specific contributions has to be supplemented with contributions on methodology for comparing the national contributions and development of joint description framework.

4. Session C and Workshop: Developing Ontologies - Tools and motivations

At the Bremen seminar, experiences regarding ontology development was presented. Also, development tools were mentioned and made available. The following presents a semi-formal structuring of the universe of discourse. The tentative structuring motivates a tentative list of research questions, which are presented in a subsequent note.

The UML-based description of subdivision in Slovenia includes the following classes: Actor, Activity and Sub-activity, and Attribute. Activities are detailled in the UseCase description, and analysed in another document. The following survey of other classes and sub-classes are based on the Slovenian description, with as little modification as possible. The table arrangement is motivated by space needs, not by content:

Documents include
  • Application
