A faceted taxonomy of semantic integrity constraints for the XML data model

Some work in the literature deal with Semantic Integrity Constraints (SIC) for XML and propose taxonomies of SIC for the XML data model. However, these taxonomies are incomplete and do not mention a basis for the classification. We propose a faceted taxonomy of SIC for XML data model that tries to fulfill these limitations. Our proposal is based on previous related taxonomies for the relational and XML data models, providing a classification that can give support to expressiveness analysis of SIC specification languages for XML data, as well as XML database management systems integrity control. We demonstrate, through examples, that our taxonomy is more comprehensive than other related taxonomies available in the literature.
