# Version marker id The version marker id is a string only containing a single asterix symbol `*` It is used to mark [versioned-dwllve-nodes](../graph/versioned-dwllve-node.md) in the [dwllver file format](../graph/data-with-linked-list-version-extension-row-file.md). They are marked by using a link list like in the following example: ``` 1: * 2: 3: 4: 5: ... ``` The strings enclosed by pointy brackets should be replaced by the respective node ids
