Farmland is now being regarded worldwide as well as in Turkey as a limited resource. This situation brings with it the consequences of restrictions to ownership rights. In 2005, the Soil Protection and Land Use Law was enacted in Turkey, restricting the division and transfer of agricultural land via sale and inheritance. In view of international developments in the field of cadastre, these restrictions are considered to be legal land objects. By understanding the concept of object-based cadastre, the scope and extent of these constraints can easily be identified. This study aimed to identify and model the current restrictions in Turkey on an international level. The Unified Modeling Language (UML) was used as the method. Sample applications of the restrictions on the sale of agricultural land were developed and explained, and UML diagrams were used to illustrate object-oriented workflow processes and actors. In this way, a conceptual relationship with the Land Administration Domain Model (LADM) was established and implications for the future were discussed.
