During the last couple of years, the potential of 3D and Land Administration Domain Model (LADM, ISO 2012) based cadastral registration in Malaysiahas been investigated and described in several papers, and presented at various International Federation of Surveyor (FIG) meetings. Based on these preparations, a two day workshop and additional meeting between Research and Development(R&D) staff from Department Survey and Mapping Malaysia (JUPEM) and Universiti Teknologi Malaysia (UTM) has resulted in a proposal for a comprehensive LADM country profile supporting 2D and 3D cadastral registration in Malaysia. This conceptual model consists ofseveral novel aspects for Malaysia: 3D representations (incl. legal spaces around utilities), full version management, linking of database information and source documents, and basic property units (grouping of spatial units in one basic administrative unit with same rights attached). In order to assess the new conceptual model, before taking further implementation decisions, a prototype system was developed to discover the possibilities and limitations of the conceptual model. Experience from the prototype development will be used to further improve the conceptual model, before actual implementation. The steps in developing this prototype include: 1. deriving the technical model (Oracle spatial) from the conceptual model, 2. convert some (and/or create) sample JUPEM/land office data into model, and 3. develop prototype (based on MicroStation) to view and edit. During the development of the conceptual model based on LADM, many design decisions have been taken and documented, resulting in the Malaysian country profile (Zulkifli et al 2014). Next, again many design decisions have to be taken to develop the database schema during the conversion from conceptual to technical model. In this phase the nature of the design decision is more technical and closer to actual implementation.
