As the number of RDF datasets being published on the Web increases, so does the need to establish the quality of their contents. The generation of RDF datasets may be performed by transforming non-RDF resources to RDF. This process is termed “uplift”, and often involves the definition of mappings where the rules on how data is transformed to RDF are described. Another use for mappings is found when defining relationships, or links, between concepts within those datasets. The definition of these mappings involves various quality related activities in which these are iteratively refined until they satisfy the user's expressed requirements. Information related to such requirements and quality related mapping activities, however, is rarely captured or provided. In this paper, we present the Mapping Quality Vocabulary (MQV), which enables quality metadata and provenance information relating to the assessment …
