GitHub user wangzhewwzz added a comment to the discussion: 关于电网拓扑数据导入
您好 我现在贴出我的完整脚本和数据块
最下面是导入报错说属性键'source_label'不存在。这是因为在HugeGraph的schema中还没有定义这个属性键。我们需要在schema定义文件中添加这个属性键的定义
那么我改怎么定义呢

主题：Re: [apache/incubator-hugegraph] 关于电网拓扑数据导入 (Discussion #2917)
edge_connected_to.csv 里的 source_label 和 target_label 两列，应该分别填写 from 和 to 对应顶点的
label（类型），而且必须和 schema.groovy 里定义的顶点 label 完全一致（区分大小写）。
举例：假设有一行
id,from,to,label,source_label,target_label
edge_2,XLD-3445,HWX-3087,CONNECTED_TO,LineSegment,StationHouse
这里 XLD-3445 在 vertex_linesegment-1.csv 里，label 是 LineSegment；HWX-3087 在
vertex_stationhouse-1.csv 里，label 是 StationHouse，所以 source_label 填
LineSegment，target_label 填 StationHouse。
你可以用 Excel 或脚本批量查找 from/to 在各自顶点 CSV 里的 label，然后填到 source_label/target_label
列。只要这两列和 schema.groovy 里的顶点 label 完全一致，struct.json 的 value_mapping
就能正确筛选和导入所有关系，否则会被跳过但不会报错（官方文档说明）。
导入后建议用 REST API 查询边类型和数量，确认关系是否齐全。如需自动化脚本或 Excel 公式思路可以随时补充需求。
