Page Summary Formats

This page describes existing formats that enable an author to publish a summary description for a page. Whether or not this is worthy of doing research (e.g. page-summary-examples, page-summary-brainstorming) for a microformat is open to debate. Nonetheless, it doesn't hurt to at least have a place to document existing formats.

meta description

HTML4.01 provides meta description as an example in Appendix B: Performance, Implementation, and Design Notes of the HTML 4.01 spec. E.g.

<META name="description" content="Idyllic European vacations">

Product Support

Google search results display the value of the meta description element for a page when that page is listed in Google search results.

Flaws

• Invisible. meta description is invisible metadata on the page and therefore violates microformats principles.

• Depends on head element. This summary format depends on the author having access to the head element which in many (most?) web authoring/publishing scenarios the content author has no access.

microsummary

Mozilla has introduced a proprietary format called "microsummary", which is used in Firefox 2.0's support for bookmarks.

Flaws

• Invisible. Though different from meta description in that the link tag is used to relate to a summary at another URL - this doesn't actual markup the summary content itself. Since the content is not visible on the page itself, an author could easily change the page content without noticing or even knowing to bother to change the referenced "summary" page/resource. Thus this method has all the same flaws of typical invisible metadata publishing, which is that overtime it rots, becomes out of date, unreliable and untrustworthy in general.

• Depends on head element. This summary format depends on the author having access to the head element which in many (most?) web authoring/publishing scenarios the content author has no access.
