This page documents all changes made to the database or calculation methodology. Calculated results from different database versions may differ.
Note: our database is incrementally built nightly.
Current Database versions
Version 2.0.0, Release Date: 04/13/2016
- Equivalent to old version "2014.04.18"
- Use major.minor.patch versioning, inspired by semantic versioning, but for data. Arbitrarily choose "2" as the initial major version.
- When new data is added (typically nightly), db version remains the same
- When new kinds of data are added, bump the patch (x.y.Z) version
- When data organization (schema) changes, bump the minor (x.Y.z) version
- When calculation methodology changes, bump the major (X.y.z) version
Data from the earlier 'Materials Genome' web site, served prior to 10/10/2011, is no longer supported.
