NDR Data Quality Guidelines
This is an initiative of National Data Repository (NDR) Workgroup that was donated to Energistics at the time it was published in 2018. These guidelines are not specifications but were developed by consensus among the companies who participated and reviewed them in conjunction with three NDR conferences, 2012, 2014 and 2017.
Here are the NDR Data Quality Guidelines:
Part 1: Background and Case for Change-A4-Final
Part 2: Business Rules Fundamentals-A4-Final
Part 3: Implementation Guide-A4
