2.2.7.4.12. Dictionary compliance

| top | pdf |

(27) Dictionary files containing the definitions and attribute sets for the data items contained in a CIF should be identified within the CIF by some or all of the data items[Scheme scheme37] corresponding to DDL1 dictionaries or[Scheme scheme38] for DDL2 dictionaries. Where no such information is provided, it may be assumed that the file should conform against the core CIF dictionary.

(28) The _audit_conform data items may be looped in cases where more than one dictionary is used to define the items in a CIF and they may include dictionaries of local data items provided such dictionary files have been prepared in accordance with the rules of the appropriate DDL.

(29) A detailed protocol exists for locating, merging and overlaying multiple dictionary files (McMahon et al., 2000[link]) (see Section 3.1.9[link] ).
