Semantic interoperability represents harmonized terminology and interpretation of concepts

Legal interoperability develops directives, rules, parameters and instructions for managing business work flow considering information and communication incorporation in the business

Inter-community interoperability includes ensuring consideration of providing a unique portal to perform various tasks and application in land administration.

Technical interoperability is the development of standard communication, exchange, modelling and storage of data information as well as access portals and interoperable web services equipped with user-friendly interfaces.

Interoperability Toolkit in e-Land Administration

Data management tools: To facilitate and manage the development or

intensification land information from multiple distributed sources.

Enterprise architecture design tools: To facilitate and support development of plug-and-play

Enterprise Systems and Architectures using a Web-based Foundation

Access and sharing tools : To facilitate the development of a web-based access in a

seamless and integrated view Decision support and exploitation tools : To facilitate decision-support applications that draw on

multiple, distributed spatial data resources

Conclusion 1: Research Problem

The current cadastral data model does not effectively provide interoperability among land administration subsystems and cannot facilitate delivering sustainable development.
