Neo4j到OrientDB不能创建顶点

Question

我想从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。

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

Answer 1

您正在使用哪个版本OrientDB

？

OrientDB有一个模式，所以它试图自动创建vertice和边界类。您可以使用非事务性图表：g = new com.tinkerpop.blueprints.impls.orient.OrientGraphNoTx();

Answer 2

谢谢卢卡的快速回复。它仍然没有帮助。它看起来使用gremlin从neo到orient的负载不会创建顶点。但是，当我创建数据库并从相同的GraphML文件导入相同的数据时，它只是无误地导入所有数据。然后，我比较了neo和orient图形用户界面获取近似类似的视图，但是neo显示所有对象（节点，关系..）的属性，但是orient没有明确地向他们显示任何属性。 Orient是否隐式维护属性？
