组织徽标的正确RDFa语法是什么？

Question

我正在尝试使用Google的Structured Data Testing Tool使我的文章页面具有有效的RDFa。我无法让它接受组织徽标。它总是抱怨“ URL字段的值是必需的”。我尝试将徽标url添加为“ url”，“ src”和“ content”，如下所示。香港专业教育学院也试图把一个实际的<img>标签与property =“ logo”，在那里，但我不能摆脱错误信息。有人解决了吗？

<div vocab="http://schema.org/" typeof="Article">
    <h1 property="headline name">My Amazing Article Title</h1>
    <meta property="articleSection" content="Sports" />
    <meta property="image" content="https://www.example.com/image.jpg" />
    <meta property="datePublished dateModified" content="2020-01-13" />

    <span property="author publisher" typeof="Organization">
        <meta property="name" content="MyCompanyName" />
        <meta property="logo" src="https://www.example.com/logo.png" url="https://www.example.com/logo.png" content="https://www.example.com/logo.png" />
        <meta property="url" content="https://www.example.com/" />
    </span>

    <div property="articleBody">
        Bla bla bla
    </div>
</div>

要查看确切的错误，您可以将以上代码段复制并粘贴到Google的工具中，以查看我看到的内容。顺便说一句，如果我完全省略徽标，Google会抱怨需要徽标。
