ucR Based Interoperable Spatial Information Model for Realizing Ubiquitous Spatial Infrastructure

Spatial information is very important because context such as location information is one of the key issues to realize ubiquitous spatial infrastructure. However, there are many specifications for spatial information model and establishing a common infrastructure for spatial information model is difficult. To solve the problem, we propose a new spatial information model based on ucR. Our model has high scalability because it is based on dynamic linking. We use triplestore to build our database, and its schema is more flexible and extensible than relational database schema. Moreover, we propose a flexible method to create new geographic identifiers by using combination of registered geographic identifiers. In addition, we realize the interoperability between our model and other spatial information models.
