Analysis of possibilities for linking Land Registers and Other Official Registers in the Republic of Croatia based on LADM

Weak or non-existing linkage of official registers in the Republic of Croatia and the data redundancy as an inevitable outcome of such a state are the causes of various unwanted consequences for the relevant public authorities, as well as for citizens and companies as the end-users of that data. In this paper we present the results of an analysis of the status of the redundancy within the Croatian land administration-related registers. Following the analysis, suggestions are given on how the effectiveness of the analyzed registers can be increased by introducing a linking based on the Land Administration Domain Model (LADM). The proposed linkages were created by extending the Unified Modelling Language (UML) object classes of the LADM. The compliance analysis between registers and the LADM was conducted by using schema matching. Schema matching is a set of techniques used for comparing schemas (usually referred to as data models), and is well known within the database research domain. The results of the analysis were used to determine in which direction to go with extending of the LADM. All of the outputs of this research can be used to create a strategy for improving the effectiveness of the overall system of registers, which in turn should result in an overall economic progress of the country.
