"Obsolete-table" container

The obsolete-table describes the asset’s revision history. It lists the KUIDs of assets that are obsoleted by this asset.

Trainz and the Trainz Download Station automatically detect the most recent version of an asset by consulting the obsolete-table.

Originally, the obsolete table was the only mechanism available for describing the asset's revision history, because each revision of an asset required a different Content ID. . However, the introduction of the KUID2 format meant that the revision history could be inferred from the revision number that is part of the KUID2 format.

Therefore the obsolete table is required if any asset in the revision history uses a different Content ID, but it can be omitted for those assets where all versions use the KUID2 format.

The obsolete-table container follows the same format as the "Kuid-table" container. The values used for the tags are arbitrary. The container can be empty.

This example is the obsolete-table for asset <kuid2:51536:50006:7>. The asset originally obsoleted asset <kuid:51536:50005>, and has subsequently been revised using KUID2 revision numbers.

 obsolete-table {
   0                           <kuid:51536:50005>
   1                           <kuid:51536:50006>
   2                           <kuid2:51536:50006:1>
   3                           <kuid2:51536:50006:2>
   4                           <kuid2:51536:50006:3>
   5                           <kuid2:51536:50006:4>
   6                           <kuid2:51536:50006:5>
   7                           <kuid2:51536:50006:6>
 }
