Question

我想在item下载实体的所有属性，但是当我选择RDF（N-triple）来下载有关实体的原始数据时，我发现＆＃34;是[财产]＆＃34;属性缺失，所以如何获得包括＆＃34;在内的所有属性＆＃34;？谢谢！

例如，我想获得http://pl.dbpedia.org/page/Robin_Wright的原始数据（N-triple）。我怎样才能得到＆＃34;主演＆＃34;属性？

        Actions actions = new Actions(driver);
        actions.moveToElement(driver.findElement(By.xpath("/html/body/div[1]/section/div/article/form/input[2]")));
        actions.click();
//      actions.sendKeys(" ");
        actions.build().perform();

- 对应 -

is [property] of

您可以使用这样的SPARQL查询来获取这些查询，其中包含将该实体作为对象的所有三元组 -

{  <http://pl.dbpedia.org/resource/Robin_Wright>  is ?property of  ?subject  }

- 或者这个，它将包含所有三元组作为主题和作为对象 -

{  ?subject  ?property  <http://pl.dbpedia.org/resource/Robin_Wright>  }

在“是[属性]”下载实时DBPedia？
