Use GLB and MIG prefixed Global Variables

Maintained By	The Sydney BW Integrators Group
Proposed By	Matt Milligan
Applies To BW 5	✓
Applies To BW 6	?

Overview

1. Prefix global variables with GLB_ if their values does not vary between environments.
2. Prefix global variables with MIG_ if their values do vary between environments.

Rationale

• The GLB_ prefix creates a clear indication that the global variable does not need to be modified when deploying to a environment.
• • The MIG_ prefix creates a clear indication that the global variable does need to be modified when deploying to a environment.

Alternatives Considered

TODO

Positives:

• TODO

Negatives:

• Doesn't work with all text (e.g. text containing :)

Use XPATH Strings

Positives:

• Works with all text

Negatives:

• Not immediately clear if the mapped value is constant or a complex XPATH expression
• Slower to evaluate (the XPATH expression parser must be invoked)

TODO:

• Add list of unsupported characters.
• Add BW 5 screenshot showing XSLT constant.
• Add BW 5 screenshot showing XPATH string.
• Add steps (including screenshots or video) showing how to create XSLT constants in BW 5 mappers.
• Check if this standard makes sense to apply to BW 6
