3.1.5.1. The dictionary identification block

| top | pdf |

As mentioned above, the dictionary file must contain information that unambiguously states its identity and version. In DDL1-based CIF dictionaries, this is achieved by itemizing the full set of dictionary attributes (see Section 2.5.6.5[link] ) within a data block named data_on_this_dictionary, as in Example 3.1.5.1[link] from the core dictionary.

Example 3.1.5.1. A DDL1 dictionary identification block.
