Implementing data exchange and interoperability on LADM country profiles using the ISO framework for enterprise interoperability standard

For a complete, harmonized and modernized land administration processes, seamless data exchange among departments within an organization, and among organizations is a fundamental requirement. Interoperability is therefore crucial and should be based on a well-developed Land Administration Domain Model (LADM) country profile for the implementation of a Land Administration System (LAS). This paper, through a research synthesis type of literature review methodology, looks into the existing documentation on interoperability in Land Administration (LA). Employing research synthesis method, analysis of the identified and existing resources is done. Since interoperability plays a role at multiple levels, it is paramount to apply a solid framework such as the Framework for Enterprise Interoperability (FEI) developed by International Standards Organization (ISO). This allows for the investigation of the critical aspects of data exchange: (i) business, processes, services and data, (ii) interoperability barriers: conceptual, technological and organizational, and (iii) interoperability approaches: federated, unified and integrated. The paper looks into the interoperability concerns and barriers and the approaches to addressing them for Land Administration against the elements of FEI. This provides an effective guideline for implementation of a LADM-based land administration system for any country.
