International Tables for Crystallography
| Definitions for multi-block data files International Tables for Crystallography (2026). Vol. G, ch. 3.3 [ doi:10.1107/97809553602060001000 ] Abstract Complex data sets are most economically described using multiple data units. In CIF data files, separate data blocks do not inherit data or attributes from other data blocks. To relate data in separate data blocks, common data names are used. The multi-block dictionary provides definitions for those data names that, while unnecessary for single-block presentations of data described by the core dictionary, become important when data are distributed over multiple data blocks. It provides a set of category keys that transform Set categories to Loop categories in order to formalise the inter-block relationships. |
