RDF查询为字符串

发布于 2025-01-25 20:09:02 字数 633 浏览 2 评论 0原文

我是RDF和SPARQL的新手。最近，我试图从Turtle File中查询数据，并希望将其放入列表中。但是我得到的是一堆'rdflib.term.literal'。如何将其转换为可以附加到列表的字符串？

query =f"""
    SELECT (STR(?goal) AS ?label)
    WHERE {{
        {sub} {predi} {obj} .
    }}"""

    g.query(query)

    try:
        return g.query(query).goal

    except:
        result = []
        for item in g.query(query):
            result.append(item.label)
            print(type(item.label))
        return result

这是我制作的代码，但不起作用。

I am new to RDF and SPARQL. Recently I tried to query the data from turtle file, and want to put it in a list. But what I've got are bunch of 'rdflib.term.Literal'. How can I convert it to string that can be append into list?

query =f"""
    SELECT (STR(?goal) AS ?label)
    WHERE {{
        {sub} {predi} {obj} .
    }}"""

    g.query(query)

    try:
        return g.query(query).goal

    except:
        result = []
        for item in g.query(query):
            result.append(item.label)
            print(type(item.label))
        return result
