JSON-LD的错误展开

Question

我正在学习使用 JSON-LD，但我被这个问题困住了。这是我的文档...

{
"@context": {
    "dbr": "http://dbpedia.org/resource/",
    "xsd": "http://www.w3.org/2001/XMLSchema#",
    "italy": "dbr:Italy_national_football_team",
    "ita_player_base_url": "italy:/",
    "foaf": "http://xmlns.com/foaf/0.1/",
    "team": "foaf:Organization",
    "player": "foaf:Person",
    "player_of": {
        "@id": "foaf:member",
        "@type": "@id"
    },
    "plays_with": {
        "@id": "foaf:knows",
        "@type": "@id"
    },
    "name": {
        "@id": "foaf:name",
        "@type": "xsd:string"
    },
    "number": {
        "@id": "foaf:status",
        "@type": "xsd:positiveInteger"
    }
},
"@graph": [{
    "name": "Buffon",
    "number": "1",
    "@type": "player",
    "player_of": "italy",
    "@id": "ita_player_base_url:Buffon"
}, {
    "name": "Insigne",
    "number": "20",
    "@type": "player",
    "player_of": "italy",
    "@id": "ita_player_base_url:Insigne",
    "plays_with": "ita_player_base_url:Buffon"
}]}

然后，如果我将其粘贴到 JSON-LD 到 GIF 服务（或其他所有内容），我会发现播放器是 "player_of":"domainOfTheValidator/italy" 而不是 "player_of":"http://dbpedia.org/resource/Italy_national_football_team" 为什么会这样？显然，如果我把 "player_of": "dbr:Italy_national_football_team" 而不是 "player_of": "italy" 就可以了……我快疯了。

Answer 1

A compact IRI 由一个前缀、后跟 :、后跟一个后缀组成。

使用 "italy": "dbr:Italy_national_football_team" 定义前缀 (italy)。当你想在一个值中使用它时，你必须使用冒号 (:) 后跟一个后缀（在你的例子中是空的）。

所以

"player_of": "italy",

你必须使用

"player_of": "italy:",
