Data Type List
| Data Type Code | Primitive Type Code | Regular Expression | Description |
|---|---|---|---|
| any | char | .* | A catch all for items that may take any form... |
| atcode | char | [][ _(),.;:"&<>/\{}'`~!@#$%?+=*A-Za-z0-9|^-]* | Character data type for atom names ... |
| code | char | [_,.;:"&<>()/\{}'`~!@#$%A-Za-z0-9*|+-]* | code item types/single words ... |
| float | numb | -?(([0-9]+)[.]?|([0-9]*[.][0-9]+))([(][0-9]+[)])?([eE][+-]?[0-9]+)? | int item types are the subset of numbers that are the floating numbers. |
| idname | uchar | [_A-Za-z0-9]+ | idname item types take the form... |
| int | numb | -?[0-9]+ | int item types are the subset of numbers that are the negative or positive integers. |
| line | char | [][ \t_(),.;:"&<>/\{}'`~!@#$%?+=*A-Za-z0-9|^-]* | char item types / multi-word items ... |
| name | uchar | _[_A-Za-z0-9]+\.[][_A-Za-z0-9%-]+ | name item types take the form... |
| symop | char | ([1-9]|[1-9][0-9]|1[0-8][0-9]|19[0-2])(_[1-9][1-9][1-9])? | symop item types take the form n_klm, where n refers to the symmetry operation that is applied to the coordinates in the ATOM_SITE category identified by _atom_site_label. It must match a number given in _symmetry_equiv_pos_site_id. k, l, and m refer to the translations that are subsequently applied to the symmetry transformed coordinates to generate the atom used. These translations (x,y,z) are related to (k,l,m) by k = 5 + x l = 5 + y m = 5 + z By adding 5 to the translations, the use of negative numbers is avoided. |

| uchar1 | uchar | [+]?[A-Za-z0-9] | data item for 1 character codes |
| uchar3 | uchar | [+]?[A-Za-z0-9][A-Za-z0-9][A-Za-z0-9] | data item for 3 character codes |
