 Use [importAggregatedGitLog.sh](./scripts/importAggregatedGitLog.sh) to import git log data in an aggregated form into the Graph. It works similar to the [full git log version above](#import-git-log). The only difference is that not every single commit is imported. Instead, changes are grouped per month including their commit count. This is in many cases sufficient and reduces data size and processing time significantly. Here is the resulting schema:
 
 ```Cypher
-(Git:Log:Author)-[:AUTHORED]->(Git:Log:ChangeSpan)-[:CONTAINS]->(Git:Log:File)
+(Git:Log:Author)-[:AUTHORED]->(Git:Log:ChangeSpan)-[:CONTAINS_CHANGED]->(Git:Log:File)
