我已经确认了一种激活/停用我的构造函数的尴尬方式。请注意，我正在使用以下子属性结构：
spin:constructor
sxxicc:sxxiPub7ComplianceCheckRule
sxxicc:activeSxxiPub7ComplianceCheckRule
我将以下构造函数创建为sxxicc:sxxiPub7ComplianceCheckRule：
# THE MAJOR FUNCTION IDENTIFIER IS INVALID. (511 02)
CONSTRUCT {
?this sxxicc:pub7ProposalHasComplianceMessage "THE MAJOR FUNCTION IDENTIFIER IS INVALID. (511 02)"^^xsd:string .
}
WHERE {
?this a sxxicc:Pub7Proposal .
?this sxxicc:pub7ProposalHasDataItem ?dataItem511 .
sxxicc:Pub7Proposal sxxicc:activeSxxiPub7ComplianceCheckRule ?thisRule .
?thisRule rdfs:comment "THE MAJOR FUNCTION IDENTIFIER IS INVALID. (511 02)"^^xsd:string .
?dataItem511 a sxxicc:Pub7DataItem511 .
?dataItem511 sxxicc:pub7DataItemHasStringValue ?majorFunctionID .
?this sxxicc:pub7ProposalHasDataItem ?dataItem102 .
?dataItem102 a sxxicc:Pub7DataItem102 .
?dataItem102 sxxicc:pub7DataItemHasStringValue ?serialNumString .
BIND (SUBSTR(?serialNumString, 1, 4) AS ?orgString) .
FILTER (((((?orgString = SUBSTR("AF X"^^xsd:string, 1, 4)) || (?orgString = SUBSTR("AR X"^^xsd:string, 1, 4))) || (?orgString = SUBSTR("N X"^^xsd:string, 1, 4))) || (?orgString = SUBSTR("NS X"^^xsd:string, 1, 4))) || (?orgString = SUBSTR("MC X"^^xsd:string, 1, 4))) .
FILTER (!(((((((((((?majorFunctionID = "AIR OPERATIONS") || (?majorFunctionID = "GROUND OPERATIONS")) || (?majorFunctionID = "SEA OPERATIONS")) || (?majorFunctionID = "SPACE OPERATIONS")) || (?majorFunctionID = "RANGE OPERATIONS")) || (?majorFunctionID = "SURVEILLANCE/RECONNAISSANCE")) || (?majorFunctionID = "SPECIAL OPERATIONS")) || (?majorFunctionID = "C3")) || (?majorFunctionID = "SUSTAINING OPERATIONS")) || (?majorFunctionID = "DOMESTIC SUPPORT OPERATIONS")) || (?majorFunctionID = "OTHER OPERATIONS"))) .
}
此查询与激活最相关的行是：
sxxicc:Pub7Proposal sxxicc:activeSxxiPub7ComplianceCheckRule ?thisRule .
?thisRule rdfs:comment "THE MAJOR FUNCTION IDENTIFIER IS INVALID. (511 02)"^^xsd:string .
默认情况下，此规则无法生成其错误消息，因为它具有超属性但没有活动子属性。我通过断言设置为“Sight Seeing”（不是有效的主要功能标识符）来确认这sxxicc:Pub7Proposal一点dataItem511。这个构造函数没有产生它的错误信息。
然后我从 OpenRDF 工作台“修改/SPARQL 更新”运行以下 SPARQL 更新查询，以将此构造函数更改为“活动”：

INSERT {
sxxicc:Pub7Proposal sxxicc:activeSxxiPub7ComplianceCheckRule ?thisRule .
}
WHERE {
sxxicc:Pub7Proposal sxxicc:sxxiPub7ComplianceCheckRule ?thisRule .
?thisRule rdfs:comment "THE MAJOR FUNCTION IDENTIFIER IS INVALID. (511 02)"^^xsd:string .
}
我断言了另一个相同sxxicc:Pub7Proposal的（不同的 IRI），并且该规则确实抱怨“Sight Seeing”不是有效的主要功能标识符，正如预期的那样。
请注意，具有相同形式但使用DELETE替换上述INSERT子句（相同的三元组）的子句的查询可能会动态地使构造函数无效。更准确地说，它将防止再次生成错误消息。
这是完成构造函数的动态激活和停用的低效方式。我正在做很多工作来绕过锚定构造函数的空白节点。我使用规则的注释来确保唯一性，并且我使用自己的子属性来限制规则搜索自身的范围。我希望有一种更好的方法来动态激活/停用构造函数规则，而无需完全加载/卸载它们。如果规则引擎本身理解“活动”的概念，这样“非活动”规则就不会不必要地运行而只是发现它们是非活动的，那就太好了。
