本页面描述的是内置在Semantic MediaWiki（SMW）当中的那些特殊属性（special properties）。它们是该系统正常运行所必需的。它们将以斜体形式显示在页面的事实框当中，特殊页面Special:Browse 之上以及特殊页面Special:Properties之上。
自Semantic MediaWiki 1.4.0版起，就像所有其他属性一样，特殊属性亦可用在浏览界面以及行内查询当中。
详情请参见帮助页面属性和类型。
特殊属性的名称和别名将予以保留，无法用于其他属性。
此外，应当仅仅依照文档所记载的相应用途来使用特殊属性！
并不一定要为特殊属性创建页面。即使是您的维基站点并没有为其提供任何的属性页面，它们也会表现出它们的特殊行为。
下表所列出的页面对特殊属性进行了概述并提供了相应文档页面的链接。
在一项扩展当中，您可以利用smwInitProperties钩子创建自己的特殊属性。例如，可参见在Semantic Extra Special Properties（语义额外特殊属性）扩展当中的使用情况。
