Downloaded from https://www.everyspec.com MIL-STD-31000A APPENDIX B B.7.8 Metadata. Meta Data is data that supports the definition, administrative or supplemental data package. Metadata includes all relations, parameters and system information used in a model. This data resides at the model and feature level. Certain information such as title block data, material, block tolerances, etc. should be defined as parameters to allow the option for future extraction of the data. In addition, this allows the information to be displayed in any number of combination view and to easily update all instances via an associative link to the parameter name.
