Subject: Word Viewer plug-in when a MS Word is hyperlinked in a web page
No previous message | Next message →

It was just pointed out to me that I should be adding a link to
download the MS Word Viewer on any page that has a link to a MS Word
document, just as I currently add the link to download Acrobat Reader
for any page with a link to a PDF. Is this common practice? I'm
worried that there are different versions of Word Reader depending on
the version of MS Word, there doesn't appear to be a MacIntosh
version and no persistent link location, etc. I see that there are
other Viewers for Excel and Power Point, and wonder how accessible
any of these applications are.

Our college lets faculty post PDF, MS Word, rtf, or txt, Excel or csv
files, to make materials available to their students. I've always
added the Acrobat Reader download link, but never linked to a plug-in
for text or spreadsheet files. It seems slightly different from a
PDF, since Word and Excel documents download and are not usually
displayed in the browser. Although I have noticed that on my PC
Internet Explorer is displaying MS Word files in a browser mode (but
of course I have the MS Word application on my machine). Other
browsers are not likely to have that feature.

Alternatively, I could restrict links to html or PDF documents, but
often faculty want the student to use the MS Word file as a working
document for an assignment. Many faculty simply find it easier to
post the MS Word document than convert it to PDF or HTML, so I have
lots of these.

I'd be interested in what the group is providing on web pages with
links to content like MS Word or Excel files.

Not answering your question directly, but on that general topic...

Though I'll probably burn in accessibility hell for it, I have to admit
that I've stopped adding links to download PDF readers etc for common
formats.

Instead of adding download links on all pages I would, at a stretch,
create a single page with links to some standard viewers, and only
maintain that one.

It's not common.

For PDF, such links are relatively common, but they tend to be
counter-productive. I've seen too many statements like "To view PDF
documents, you need Adobe Acrobat Reader 3.0" with a link. They were
wrong in the beginning (I don't need the stuff, there are other PDF
viewers as well) and they have turned more wrong as Adobe changed the
software name, the version became obsolete, and perhaps someone broke the
link too. Surely such statements should be updated, but get real: authors
who write them just don't bother, they don't even think of the issue.

I don't think WCAG recommends such links; the text at
http://www.w3.org/TR/WAI-WEBCONTENT/#gl-use-w3c
would be the natural place to such things, but it doesn't. It tells you
that if you use PDF or Word format, "provide an alternative version of
the content that is accessible". That might be unrealistic at times, but
the same applies to WCAG and accessibility goals in general.

In practical terms, people who don't have a PDF or Word viewer hardly
benefit from a link. There's much more than just a download address that
you need (including some idea of how to install software, the right to do
so, and some idea of how to learn to use such software), and if you have
most of the rest, you'll find a download address on your own. - A download
link, or prerably a link to a page on the program (incl. a download link),
would make sense for a relatively _rare_ program, such as a specialized
viewer for a specialized data format.

If you're in the US and Section 508 really matters to you, then you need
to include a link, see
http://www.access-board.gov/sec508/guide/1194.22.htm#(m)
and this apparently applies to Word as well as to PDF. The Section 508
rules also say that the software linked to must satisfy accessibility
requirements; don't ask _me_ how to find such viewers.

Literally, the Section 508 rule requires "a link to a plug-in or applet",
but I think we can interpret this so that a link a page _about_ a plug-in
is acceptable. And it makes much more sense, since that page may then
contain alternatives, general information, instructions, etc., and not
just a download link.

That's one of the reasons why you should link to an information page
rather than the software directly (a download link). That would be much
better in accordance with the spirit of Section 508, and formally, a link
to a page containing (prominently) a link to X can be construed as
providing a link to X. (I hope your lawyer would agree...)

Such a technicality is not relevant here in my opinion, though the wording
about "plug-ins" is somewhat disturbing. Anyway, I'm used to seeing both
PDF and Word (and Excel) documents opening inside the browser window, and
whether they do that depends on the system (especially the browser) and
its settings.

Perhaps they don't know that HTML documents can be opened in MS Word.
There are problems with that, but for simple dual publication (as online
pages and as documents editable by users in word processors), reasonably
discriplined HTML with CSS should work fine, as long as users are informed
about the possibilities.

That's the big issue. There is no simple solution. Reasonably discriplined
Word with styles converts reasonably to HTML with CSS half-automatically,
but even the starting point is usually poor: the Word documents are not
disciplined.

Linking to the viewers may be a good usuability practice, but does little to aid in accessibility. MS Word Reader is only partially accessible meaning that when using screen reader and this tool together, you can read very simple pages but not tables or a page with complex formatting. The MS Excel and Power Point readers are not 508 compliant and not accessible. Microsoft's response is they can't understand why a person just would not convert the page to HTML. Simple, in a good many cases the HTML page will not be accessible or meet the 508 standards or accessible-- and this method usually produces a web page with bloated code.

In my opinion, any page where you choose to link to powerpoint documents, excel documents, and possibly even Word documents (depending on complexity and design) without providing an accessible version along with the linked document, the web page does not meet 508 requirements. Specifically Standard M states "When a web page requires that an applet, plug-in or other application be present on the client system to interpret page content, the page must provide a link to a plug-in or applet that complies with §1194.21(a) through (l)." The MS PowerPoint and Excel viewers do not comply with §1194.21(a) through (l). A person who uses assistive technology, such as JAWS, aand who does not have a full version of PowerPoint or Excel on their computer, will not be able to read the linked documents as the PowerPoint and Excel documents as the viewers are not accessible. This means that it is a good usability/accessibility practice to provide an accessible alternative when posting links to these types of documents on your web site.
