Source File Names
[This content is no longer valid. For the latest information on "M", "Quadrant", SQL Server Modeling Services, and the Repository, see the Model Citizen blog.]
Use the following naming conventions for Microsoft code name “M” source files to increase discoverability of the code within each file.
Do Name an “M” Source File for its Primary Construct
Name “M” source files with the name of the primary extent, type, or computed value it contains. For example, the SoftwareComponent.m file contains the SoftwareComponent type.
Do Preserve the Casing of the Primary Construct for “M” Source File Names
Match the casing of an “M” source file name to the casing of the primary type, extent, or computed value contained in the file. In the previous example, it is incorrect to use the name softwareComponent.m for the “M” file name, because the first letter of the contained type, SoftwareComponent, is capitalized.
