Image dictionary (imgCIF)

Extended data types

The following extended data types are defined in this dictionary:

Code	Primitive data type	Regular expression construct	Description

code	char	[_,.;:"&<>()/\{}'`~!@#$%A-Za-z0-9\|+-]	code item types/single words ...
ucode	uchar	[_,.;:"&<>()/\{}'`~!@#$%A-Za-z0-9\|+-]	code item types/single words (case insensitive) ...
line	char	[][ \t_(),.;:"&<>/\{}'`~!@#$%?+=A-Za-z0-9\|^-]	char item types / multi-word items ...
uline	uchar	[][ \t_(),.;:"&<>/\{}'`~!@#$%?+=A-Za-z0-9\|^-]	char item types / multi-word items (case insensitive)...
text	char	[][ \n\t()_,.;:"&<>/\{}'`~!@#$%?+=A-Za-z0-9\|^-]	text item types / multi-line text ...
binary	char	\n--CIF-BINARY-FORMAT-SECTION--\n\ [][ \n\t()_,.;:"&<>/\{}'`~!@#$%?+=A-Za-z0-9\|^-]\ \n--CIF-BINARY-FORMAT-SECTION----	binary items are presented as MIME-like ascii-encoded sections in an imgCIF. In a CBF, raw octet streams are used to convey the same information.
int	numb	`-?[0-9]+`	int item types are the subset of numbers that are the negative or positive integers.
float	numb	`-?(([0-9]+)[.]?\|([0-9]*[.][0-9]+))([(][0-9]+[)])?([eE][+-]?[0-9]+)?`	float item types are the subset of numbers that are the floating point numbers.
any	char	`.*`	A catch all for items that may take any form...
yyyy-mm-dd	char	`\ [0-9]?[0-9]?[0-9][0-9]-[0-9]?[0-9]-[0-9]?[0-9]\ ((T[0-2][0-9](:[0-5][0-9](:[0-5][0-9](.[0-9]+)?)?)?)?\ ([+-][0-5][0-9]:[0-5][0-9]))?`	Standard format for CIF date and time strings (see http://www.iucr.org/iucr-top/cif/spec/datetime.html), consisting of a yyyy-mm-dd date optionally followed by the character 'T' followed by a 24-hour clock time, optionally followed by a signed time-zone offset. The IUCr standard has been extended to allow for an optional decimal fraction on the seconds of time. Time is local time if no time-zone offset is given. Note that this type extends the mmCIF yyyy-mm-dd type but does not conform to the mmCIF yyyy-mm-dd:hh:mm type that uses a ':' in place if the 'T' specified by the IUCr standard. For reading, both forms should be accepted, but for writing, only the IUCr form should be used. For maximal compatibility, the special time zone indicator 'Z' (for 'zulu') should be accepted on reading in place of '+00:00' for GMT.
