ABSTRACT:
Methods and apparatus are provided for mapping XML source documents to target documents using schema embeddings. According to one aspect of the invention, one or more edges in the one or more source schemas are mapped to one or more paths in at least one target schema. The disclosed mapping techniques ensure that (i) one or more source documents that conform to one or more of the source schemas can be recovered from one or more target documents that conform to the at least one target schema, if a mapping exists between the one or more of the source schemas and the at least one target schema; (ii) queries on one or more source documents that conform to one or more of the source schemas in a given query language can be answered on one or more target documents that conform to the at least one target schema; and (iii) the one or more target documents conform to a target schema.
