SPARQL查询三个子属性不起作用

[英]SPARQL query for three sub-properties does not work

问题描述

我试图进行SPARQL查询，但失败了。 我需要这样三个属性： 

SELECT DISTINCT ?locality ?museRes ?calendar ?category
FROM <http://opendata.cs.pub.ro/repo/context/TTT>
WHERE { 
 {
 ?museRes vCard:locality ?locality FILTER (regex(?museRes, "odaia_bunicii", "i")) .
 ?museRes vCard:category ?category FILTER (regex(?museRes, "odaia_bunicii", "i")).
 ?museRes vCard:hasCalendarRequest ?calendar FILTER (regex(?museRes, "odaia_bunicii", "i"))
 }
}

在罗马尼亚语OpenData SPARQL端点中

问题在于三个属性是另外三个超级属性（dcterms：spatials，dcterms：description和opendata：MuseumTour）的一部分，并且该方法不起作用。 我尝试使用OPTION运算符，但它仅向我显示？museRes和？locality值，甚至？calendar和？category也都不为空。

最后，我尝试使用UNION代替OPTION，但是它仅适用于一个UNION，并且我需要使用两个UNION运算符。

我如何在上述RDF中要求vCard：locality vCard：category和vCard：hasCalendarRequest？

            <dcterms:description>Centrul folcloric al grădiniţei Galicea Mare este situat în incinta Grădiniţei nr.1, structură a Şcolii Gimnaziale Galicea Mare, judeţul Dolj, pe drumul european E56. Pentru a readuce la viaţă şi a reînvia atât tradiţiile cât şi portul popular românesc, a luat naştere „Odaia bunicii”, un loc in care obiectele prind viaţă şi creează o atmosferă caldă, plina de dragostea ţaranilor de altadată. Expoziţia permanentă, deschisă în 2016, este concepută într-o manieră tradiţională, fiecare obiect aşteptând să fie folosit pentru a-şi arata maiestria, astfel: patul cu tablii de lemn şi saltea de paie aşteaptă să odihnească omul, măsuţa din lemn şi scaunelele aşteaptă cu nerăbdare să fie servită cina, dar şi războiul ţăranesc unde femeile ţeseau macate ne reamintesc nouă, celor mari, şi îi învaţă pe cei mici despre obiceiurile şi tradiţiile româneşti de altădată.</dcterms:description>

3-4小时后，我找到了解决方案： 

SELECT DISTINCT ?locality ?category ?calendar ?importanta
FROM <http://opendata.cs.pub.ro/repo/context/ilie>
WHERE { 
 ?a vCard:locality ?locality. FILTER (regex(?a, "odaia_bunicii", "i")).
 ?b vCard:category ?category. FILTER (regex(?b, "odaia_bunicii", "i")).
 ?c vCard:hasCalendarRequest ?calendar. FILTER (regex(?c, "odaia_bunicii", "i")).
 ?d openDataP:Relevance ?importanta. FILTER (regex(?d, "odaia_bunicii", "i")).
}
