Metadata Discovery Problem - We present a methodology for constructing a spatial ontology-based datasets navigation model to allow cross-reference navigation between datasets. We defined the structure of the dataset as metadata, the field names, and the actual values. We defined the relationship between datasets as 3-layer such as metadata layer, field names layer, and data value layer. The relationships in the metadata layer was defined as the correspondence between metadata values. We standardized the field names in dataset to discover the relationships between field names. We designed a method to discover the relationship between data values based on common knowledge datasets for each domain. To confirm the validity of the presented methodology, we applied our methodology to implement an ontology-based knowledge navigation model for actual disasterrelated processes in operation. We built a knowledge navigation model based on spatial common knowledge.
