E-Standards for Mass Properties Engineering

The purpose of this Opensource forum is to promote the development of a JAVA based Application Programming Interface for the field of Mass Properties Engineering.

This project started as a NASA LaRC Innovation Institute project in 2007 to promote the general field of mass properties engineering and to define electronic file standards and data object manipulations to support that field. Weight Engineering Journal Winter 2007 published by the Society of Allied Weight Engineers (SAWE) provides a descriptive article, "Using MPEX as a standard file format for mass properties engineering data" as introduction to the topic. SAWE Paper No. 3440, "E-Standards for Mass Properties Engineering", provides additional thoughts.

Please contact if you desire additional information or wish to have your thoughts and code enhancements included in this project. This is currently only the initial code of a project which hopefully will be greatly expanded upon by expertise from interested members in the weights engineering community.


  • is the initial code used to define project requirements and provide a template document from which to discuss goals in class structure and functionality. Currently reads an MPEX format data file and parses its datasets into comparable java objects of similar hierarchical nature. No attempt has been made to handle large data files and no object functions have been coded.
