An unified resource mapping strategy based on XML in computational grid environments

摘要

Mapping heterogenous resources is a challenging issue due to structural differences and structural inconsistencies. Based on the characteristics of XML and several extensions on the XML tree, A unified resource mapping strategy in computational grid environments is proposed for XML trees. A semantic relationship between nodes in XML trees is captured by the concept of a schema graph. Mapping are specified on the schema graph patterns of the schema graph. A mapping is not restricted by the structure of a specific XML tree. A technique for evaluating mapping is presented.
