Descriptor¶
Fully qualified class name: DDICDIModels::DDICDILibrary::Classes::DataDescription::Long::Descriptor
Definition¶
Use of a code for variable identification in the context of a data structure and a variable descriptor component.
Examples¶
Consider two variables, i.e. income and age, with values appearing in the same column. Codes “income” and “age” are descriptors. They appear multiple time in a variable descriptor component, one for each value in the variable value component. Each descriptor references one of those values. This way it’s possible to identify which values correspond to income and which ones to age.

whiteSpace |
The usual setting “collapse” states that leading and trailing white space will be removed and multiple adjacent white spaces will be treated as a single white space. When setting to “replace” all occurrences of #x9 (tab), #xA (line feed) and #xD (carriage return) are replaced with #x20 (space) but leading and trailing spaces will be retained. If the existence of any of these white spaces is critical to the understanding of the content, change the value of this attribute to “preserve”. |
