爲了完整（因爲OP問幾個API）來我重複@Joshua泰勒的解決方案，但使用OpenRDF芝麻API，而不是耶拿：

我看到了你以前的問題，但這裏沒有足夠的自足。例如，你說你想要「爲文件中的每個不同主體創建一個空白節點標識符」，但是你沒有說明「文件中的不同：主體」是什麼。由於您在詢問如何使用其中一個庫生成某些特定輸出，因此首先生成一些示例輸出。例如，你給我們看的句子應該產生的RDF是什麼？是（......; ...; ...）應該映射到三元組，還是僅僅是這個特定數據的幸運事故？ –
你想要輸出或多或少像http://pastebin.com/sFwfqLFM？ –
我的意思是應該爲上例中的句子生成的RDF。 –
