The most important change implemented in the IMDI Editor version 3.0 concerns the supported metadata categories: the Editor now supports the IMDI 3.0 standard, and all IMDI files created with this version of the Editor will automatically conform to this new standard. IMDI files created with an older version of the Editor need to be converted to the new standard.

This section first summarizes the implemented changes (see Section 2.7.1), and then describes the conversion of old IMDI files (see Section 2.7.2) and old repositories (see Section 2.7.3) to the 3.0 standard.
