问题
I want to do this for metadata purposes, rather than something that would explicitly displayed . So, for example, say my current document, Page A, is linked to from Page B e.g. a 'related article' in its sidebar. What link relation, or other markup, should I use in Page A to indicate this 'reverse linking' relationship?
回答1:
Take a look at rel attribute.
I would suggest you in order to accomplish what you wrote, use rel="next", respectively rel="prev" inside an anchor tag
回答2:
The rel attribute (which can be used on link, a and area elements) specifies the link relationship type.
In HTML5, you may only use the following rel values:
- link types defined in the HTML5 specification
- link types registered in the Microformats wiki on the page http://microformats.org/wiki/existing-rel-values#HTML5_link_type_extensions
If there is an appropriate link type depends on the specific relationship between your Page A and Page B. You only wrote "related article", but I don’t think that there would be a corresponding link type for such a general relation. I’d guess that all links on a page without a specific link type can be understood as "related".
You shouldn’t use next/prev unless your pages A and B are "part of a sequence".
If you don’t find appropriate link types, you may use RDFa Lite and/or Microdata and look for a suitable vocabulary. For example schema.org’s http://schema.org/WebPage specifies the relatedLink property:
A link related to this web page, for example to other related web pages.
It could look like (using RDFa Lite here):
<!-- on page B -->
<div vocab="http://schema.org/" typeof="WebPage">
<a href="/article-a" property="relatedLink">Article A</a>
</div>
