Index structure of metadata, method for providing indices of metadata, and metadata searching method and apparatus using the indices of metadata

摘要

A data processing architecture comprises one or more data processing components associated with a logical level such that a data processing component associated with a logical level only accepts input from one or more data processing components in a logically higher or lower logical level or an external source; a data processing component associated with a logical level only provides output to one or more data processing components in a logically higher or lower level or an external recipient system. Each data processing component can not accept input or provide output from or to a data processing component in the same logical level; and a data processing component will only accept an input that conforms to an ontology related to the logical level with which the data processing component is associated.
