Opengraph W3C 有效吗？

发布于 2024-09-01 04:34:44 字数 247 浏览 8 评论 0 原文

我想知道 opengraph 标记是否是 W3C 有效的，当我尝试验证它时，我收到以下错误：

Line 14, Column 17: there is no attribute "PROPERTY"
 <meta property="og:site_name" content="sitename">

如果它无效，它会影响我的页面排名和其他搜索引擎算法吗？

是否有可能隐藏这些属性？

原文

I would like to know if the opengraph markup is W3C valid,
I'm getting the following error when I try to validate it:

Line 14, Column 17: there is no attribute "PROPERTY"
 <meta property="og:site_name" content="sitename">

In case it's not valid, will it impact my pagerank and other search engines algo?

Is it possible to cloak those properties?

它在普通的 HTML 文档类型中无效，但是您可以使用一个文档类型来验证包括 Open Graph 在内的 XHTML 文档：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML+RDFa 1.0//EN" "http://www.w3.org/MarkUp/DTD/xhtml-rdfa-1.dtd">

请参阅此问题：属性属性的 HTML 验证错误

It's not valid in the normal HTML doctypes, but there is a doctype you can use to validate XHTML documents including Open Graph:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML+RDFa 1.0//EN" "http://www.w3.org/MarkUp/DTD/xhtml-rdfa-1.dtd">

See this question: Html validation error for property attribute

不，不是。这就是验证器报告错误的原因。

这似乎有效：

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML+RDFa 1.0//EN" "http://www.w3.org/MarkUp/DTD/xhtml-rdfa-1.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:v="http://rdf.data-vocabulary.org/#">

With this seems to work:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML+RDFa 1.0//EN" "http://www.w3.org/MarkUp/DTD/xhtml-rdfa-1.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:v="http://rdf.data-vocabulary.org/#">

这样你就解决了问题：

<!DOCTYPE html>
<html vocab="http://www.w3.org/2011/rdfa-context/rdfa-1.1">

这样你就可以在你的html中使用像这样的行：

<meta property="og:title dc:title" content="m.clinic.pt - Está em boas mãos!">

或者从列出的其他词汇表中使用(http://www.w3.org/2011/rdfa-context/rdfa-1.1) 像这样：

您可以通过 http://validator.w3.org/ 或 http ://html5.validator.nu/ 非常好。

因此，

<div vocab="http://schema.org/" typeof="Product">
   <img property="image" src="dell-30in-lcd.jpg" />
   <span property="name">Dell UltraSharp 30" LCD Monitor</span>
</div>

您可以使用以下资源：

<!-- The schema: prefix is defined in the vocabulary http://www.w3.org/2011/rdfa-context/rdfa-1.1 -->
<div typeof="schema:Product">
   <img property="schema:image" src="dell-30in-lcd.jpg" />
   <span property="schema:name">Dell UltraSharp 30" LCD Monitor</span>
</div>

一些资源 http://www.w3.org/ TR/rdfa-primer/ http://manu.sporny.org/2012/神话差异/ http://rdfa.info/

With this you are solving the issue:

<!DOCTYPE html>
<html vocab="http://www.w3.org/2011/rdfa-context/rdfa-1.1">

With this you can use lines in your html like this:

<meta property="og:title dc:title" content="m.clinic.pt - Está em boas mãos!">

or from other vocabularies listed (http://www.w3.org/2011/rdfa-context/rdfa-1.1) like this one:

You can validate it through http://validator.w3.org/ or http://html5.validator.nu/ very well.

So instead of this:

<div vocab="http://schema.org/" typeof="Product">
   <img property="image" src="dell-30in-lcd.jpg" />
   <span property="name">Dell UltraSharp 30" LCD Monitor</span>
</div>

You can have this:

<!-- The schema: prefix is defined in the vocabulary http://www.w3.org/2011/rdfa-context/rdfa-1.1 -->
<div typeof="schema:Product">
   <img property="schema:image" src="dell-30in-lcd.jpg" />
   <span property="schema:name">Dell UltraSharp 30" LCD Monitor</span>
</div>
