device and method for structuring of iso / 8824 / asn.1-spezifikation written data

摘要

In a data structuring apparatus, input character strings written in accordance with the specification of ISO/8824/ASN.1 are decomposed and keywords representative of types and attributes are detected from the decomposed character strings. Type nodes are created from the detected type representative keywords and attribute nodes are created from the attribute representative keywords. Internode linking means is provided for establishing links between the type nodes and the attribute nodes according to hierarchical relationships between them and forming a tree structure by the established links. The tree structure is traced and the input character strings are translated according to the traced tree structure into a declaration sentence which can be processed by a computer program.
