Longdesc usage

2012-02-15T16:40:23Z

Francesca:

This is an analysis of how the <img longdesc=""> attribute is used in the wild, based on the list of 62 pages which used the attribute, available at:
http://canvex.lazyilluminati.com/survey/2007-07-17/analyse.cgi/pages/tagattr/img/longdesc

The document list is included at the end of this page, numbered. When referring to pages, I just use their number.

== Errors ==

* 3, 10, 27, 31, and 46 were redirects; I did not check the pages their pointed to.
* 22, 35, and 37 no longer have the string "longdesc" in them.

== Results ==

A large number of the pages were from Wikipedia (or other MediaWiki installations): 1, 2, 6, 9, 11, 17, 19, 21, 24, 25, 29, 30, 36, 43, 45, 54, and 59. MediaWiki has a way of using longdesc particular to itself. Ignoring MediaWiki results:

* 2 pages used longdesc="" (5, 42)
* 3 pages used longdesc="..." linking to an image of some description (41, 44, 56)
* 12 pages used longdesc="..." not as an URL, but as a human-readable description:
** 4 of which look like SEO attempts (13, 18, 48, 61)
** 3 of which used the same string as they used for alt text (7, 23, 53)
** 3 of which has different alt and longdesc text (16, 28, 52)
** 1 of which used the same string as they did for title="" (15)
** 1 of which used URL-escaped text (49)
** 1 of which is in Russian, which I don't understand (32)
* 21 pages used longdesc="..." as an URL:
** 12 of which point to a location the same as one pointed to with a link nearby (20, 33, 34, 38, 40, 47, 50, 55, 57, 58, 60, 63)
** 4 of which are broken links (4, 14, 26, 57)
** 2 of which are valid links but seems not to comply with the spec (12, 39)
** 2 of which is a correct use of the element (51, 62)
** 1 of which seems to be better dealt with as a hyperlink rather than a longdesc attribute (8)

On 51, ironically, the only longdesc attribute is used on a link to an automated accessibility checker's website. 62 seems to serve up rather unhelpful text/plain one-liners for longdesc, claiming to be accessible made by a company that does accessible web design.
