3.6.9.1. History of a data block

| top | pdf |

The categories describing the history of a data block are as follows:

AUDIT group
 AUDIT
 AUDIT_AUTHOR
 AUDIT_CONFORM
 AUDIT_CONTACT_AUTHOR

Data items in these categories are as follows:

(a) AUDIT [Scheme scheme209]

(b) AUDIT_AUTHOR [Scheme scheme210]

(c) AUDIT_CONFORM [Scheme scheme211]

(d) AUDIT_CONTACT_AUTHOR [Scheme scheme212]

The bullet ([\bullet]) indicates a category key. Where multiple items within a category are marked with a bullet, they must be taken together to form a compound key. Items in italics have aliases in the core CIF dictionary formed by changing the full stop (.) to an underscore (_).

The data items in these categories are used in the same way in the mmCIF dictionary as in the core CIF dictionary (see Section 3.2.6[link] ). The data item _audit.revision_id has been added to the AUDIT category to provide the formal category key required by the DDL2 data model. The core data item _audit_block_code has been replaced by _entry.id (see Section 3.6.9.2[link]).
