WHAT IT'S USED FOR:
Segments within accession numbers usually follow a particular format, depending on the type and purpose of the segment itself. For the system to carry out accession number validation, you must select the patterns that are valid for each segment of the format.
Here are some patterns and examples:
Pattern |
Example |
'literal' |
'ART' |
nN ('n' number of numeric characters) |
2N Two numeric characters |
nA ('n' number of alpha characters) |
4A Four alpha characters |
0A (Any letter) |
|
nZ (maximum length of 'n') |
0A+4Z Up to 4 characters, must be alpha |
x (where 'x' can be any character(s)) |
'L' (for a loan format that follows the pattern L2015.1.1, L2015.1.2, L2015.2.1 etc.) |
(x,x) (where 'x' can be any number) |
(1989,1995) would become any year between 1989 and 1995, including 1989 and 1995 |
+ ("AND", i.e. must match the combination of the characteristics) |
|
; ("OR", i.e. matches of any of the list are valid) |
'P';'C';'D' |
These are only some of the pattern match settings available.
