(Auteur) Peri-urban zones in many developing world cities are characterized by slums and informal settlements. Societies in which oral traditions, stories, dances, cultural icons, and artifacts give effect to the land tenure system struggle to preserve the primary elements of their culture in a modern technological society and struggle to lay claim to “their” territories which governments frequently regard as vacant state-owned land. Post-conflict societies often deal with refugees flowing into an area, returning refugees, internally displaced persons, and collapsed land-administration institutions, providing opportunities for powerful coalitions of individuals to grab vacant land, and newly established state institutions often appropriate and reallocate vacant land that is clearly owned by someone who has fled the conflict. Conventional land registration and cadastral survey systems are seldom designed to cater to the complex set of social relationships that characterize these and numerous similar situations. Our research group is developing a software system that should be simple in its design yet sufficiently flexible to cater to a combination of different land-related applications in areas where official recognition of land tenure is uncertain. Accordingly, a most simple structure for a cadastral information model that can handle multimedia data is being explored. The model incorporates four, inter-related classes: (1) Person (representing rights holders, e.g., juristic persons, companies, and social structures); (2) Reference Instrument (e.g., a title, a deed, or some other form of reference); (3) Land Object (which includes parcels, dwellings, trees, or trap lines); (4) Media Item (includes a wide range of media files such as video clips, audio files, maps, images, and/or photographs). This model provides a great deal of flexibility, and—if used properly—a range of different types of data can be stored, related, mixed, and matched. This paper describes some of the technical challenges involved in developing the software. Copyright SaLIS |
