الآن أريد أن أقدم اختصارا آخر تقدمه سباركل، لذا; إذا كنت ستمتعني بسكريبت افتراضي آخر... , which points from parent to child and is gender-independent. With this information, can you write a query that returns Bach’s grandchildren? P:P40children. (Hypothetically.) There’s one complication here: a grandchild may be related to Bach via the mother or the father. That’s two different properties, which is inconvenient. Instead, let’s flip the relation around: Wikidata also has a “child” property, grandSuppose we’re not actually interested in Bach’s children. (Who knows, perhaps that’s actually true for you!) But we are interested in his ها هو حلي: Now I want to introduce one more abbreviation that SPARQL offers.

But we are interested in his Here’s my solution: עכשיו נציג קיצור נוסף ש־SPARQL מציע. כל עוד נוכל לזרום בצחוק על עוד תרחיש מומצא… , שמפנה מההורה לצאצא ללא תלות במגדר. עם המידע הזה, אפשר לכתוב שאילתה שמחזירה את הנכדים של באך? P:P40ים שלו. (לכאורה.) יש כאן סיבוך מסוים: נכד יכול להיות קשור לבאך דרך האימא או דרך האבא. אלו שני מאפיינים שונים, שזה מצב לא נוח. במקום, נהפוך את הזיקה: לנתונים יש גם מאפיין „צאצא”, נכדנניח שאנחנו לא באמת מעוניינים בילדים של באך. (טוב, אולי אותך זה כן מעניין!) אבל אנחנו מעוניינים בהינה הפתרון שלי: Now I want to introduce one more abbreviation that SPARQL offers.

But we are interested in his Here’s my solution: ここでSPARQLで使用可能なもうひとつの省略形を紹介したいと思います。いまいちど仮定のお話におつきあい願うことになりますが… です)、これは親が主語になって親から子への関係性になるのと同時に、子供の性別を区別しないのです。これを念頭に、バッハの孫を返すクエリを書いてみましょう。書けましたか? P:P40本当はバッハの子供には関心はなかったとしましょう。(いや、これはひょっとすると、仮定の話ではなかったかもしれませんね!)子供ではなく、その「孫」に(仮定的に)興味があったのでした。ここで厄介な問題がひとつあります。孫は父親がバッハの子供なのかもしれないし、母親がバッハの子供なのかもしれない。どちらでもありうるのです。父親と母親は別々のプロパティなので、これは面倒です。代わりにぐるっと、関係を逆転させてしまいましょう。ウィキデータには「子」というプロパティもあって(私の解答はこうです。 Now I want to introduce one more abbreviation that SPARQL offers.

But we are interested in his Here’s my solution: Nu wil ik nog een afkorting introduceren die SPARQL biedt. Dus als u een hypothetisch scenario wilt laten maken... , die van ouder naar kind wijst en geslachtonafhankelijk is. Kunt u met deze informatie een query schrijven om naar Bachs kleinkinderen te zoeken? P:P40Stel dat we niet geïnteresseerd zijn in Bach's kinderen. Maar wij zijn geïnteresseerd in zijn "kleinkinderen". Er is hier één complicatie: een kleinkind kan verwant zijn aan Bach via de moeder of de vader. Dat zijn twee verschillende eigenschappen, wat ongemakkelijk is. Laten we de relatie omdraaien: Wikidata heeft ook een "kind" eigenschap, Dit is mijn oplossing: Now I want to introduce one more abbreviation that SPARQL offers.

P:P40假设我们对Bach的孩子不感兴趣,但想了解他的“孙子”辈。注意,“孙子”可能因父亲或母亲而与Bach有关系,而这是两个不同的属性,这让事情变得复杂。让我们思维逆转,维基数据还有一个孩子(“child”)属性我的方案是这样:
