我正在尝试从 Neo4J（neo4-shell）导入数据并加载到 OrientDB（gremlin.sh）中。然而，OrientDB 无法创建顶点，并且由于以下原因似乎失败了。

gremlin> g.loadGraphML('/tmp/out.graphml');

谢谢卢卡的快速回复。它仍然没有帮助。使用 gremlin 从 neo 到 orient 的负载似乎不会创建顶点。但是，当我创建数据库并从同一个 GraphML 文件中导入相同的数据时，它只是毫无错误地使用它，并且所有数据都已导入。然后我比较了 neo 和 orient Graph UI 获得了接近相似的视图，但是 neo 显示了所有对象（节点、关系..）的属性，但 orient 没有显式地向它们显示任何属性。orient 是否隐式地维护属性？

您使用的是哪个 OrientDB 版本？

OrientDB 有一个模式，所以它试图自动创建顶点和边类。您可以将非事务性图表与：g = new com.tinkerpop.blueprints.impls.orient.OrientGraphNoTx();
