Purpose
P1. Purpose
P1.1 Introduction
The purpose of this MEG is to define the guidelines for the representation of Calculated Results terms within the Logical Data Dictionary and the MISMO standard.
P1.2 Audience
This MEG was written for the following groups:
- MISMO Workgroup members developing MISMO messages.
- Designers and users of systems that create and consume the XML instance documents used in Real Estate Finance transactions.
- Technical or business professionals wishing to evaluate MISMO specifications.
P1.3 Terminology
The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” in this document are to be interpreted as described in RFC 2119
.
- MUST - This word, with the term “REQUIRED”, indicates an absolute requirement of the specification.
- MUST NOT - This phrase indicates an absolute prohibition of the specification.
- SHOULD - This word, or the adjective “RECOMMENDED”, means that there may exist valid reasons in particular circumstances to ignore a particular item, but the full implications must be understood and carefully weighed before choosing a different course.
- SHOULD NOT - This phrase, or the phrase “NOT RECOMMENDED” means that there may exist valid reasons in particular circumstances when the particular behavior is acceptable or even useful, but the full implications should be understood and the case carefully weighed before implementing any behavior described with this label.
- MAY - This word, or the adjective “OPTIONAL”, indicates that the specification allows the designer to choose whether or not to comply.
P1.4 Assumptions
The information supplied in this document reflects the MISMO architecture development and interoperability principles at the time of writing. It is a living document, which will be updated as required to reflect the evolving nature of XML technologies and service requirements identified by the MISMO constituency.

C1.1 Guidelines
| Ref |
Guideline |
| 22.1 |
Terms MUST meet one of the following criteria in order to use the Calculated Results Field designation:
-The calculated data value needs to be used by parties who may not be able to calculate the resultant field.
-The component pieces may not exist in order to perform the calculation at a later point in time.
|
| 22.2 |
All entries in the Logical Data Dictionary that are a calculated result from multiple components that already exist in the LDD SHALL have the verbiage “CALCULATED RESULTS FIELD” included at the end of the term definition. Calculated results terms should be used only when necessary. |
| 22.3 |
Calculated results terms SHOULD include a description of the calculation used to arrive at the value. |
