Abstract: The semantic geospatial web illustrates the use of geospatial semantics. The geospatial data are organised through catalogues containing metadata records, which can be queried in order to give access to related resources. Metadata, which refer to data describing data, include the quality of them where many values are fuzzy and/or uncertain. Different standards exist but the imperfection of knowledge is not well taken into account. We are interested in the Dublin Core Metadata Initiative and Resource Description Framework language of the semantic web. We have extended its fuzzy version.

Keywords: geographic metadata; ontology; RDF; resource description framework; RDFS; conceptual graphs; fuzzy; SIG; data quality; data uncertainty; data imprecision; spatial data; geospatial semantics; semantic web; Dublin Core.
