Neo4j到OrientDB不能創建頂點

Question

我想從Neo4J（neo4-shell）導入數據並加載到OrientDB（gremlin.sh）中。然而，OrientDB無法創建頂點，並且由於以下原因似乎失敗。

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

And data looks like this

Answer 1

您正在使用哪個版本OrientDB

？

OrientDB有一個模式，所以它試圖自動創建vertice和邊界類。您可以使用非事務性圖表：g = new com.tinkerpop.blueprints.impls.orient.OrientGraphNoTx();

Answer 2

謝謝盧卡的快速回復。它仍然沒有幫助。它看起來使用gremlin從neo到orient的負載不會創建頂點。但是，當我創建數據庫並從相同的GraphML文件導入相同的數據時，它只是無誤地導入所有數據。然後，我比較了neo和orient圖形用戶界面獲取近似類似的視圖，但是neo顯示所有對象（節點，關係..）的屬性，但是orient沒有明確地向他們顯示任何屬性。 Orient是否隱式維護屬性？
