QA Focus Surveys
QA Focus carried out a number of surveys
of project Web sites in September 2002 in
order to identify compliance with standards
and best practices.
Compliance with
HTML standards
Compliance with

The surveys have used Web-based tools
which enable projects to repeat surveys
without needing access to specialist tools

Survey of HTML
Compliance
The W3C’s HTML validation service was
used to analyse compliance with HTML
standards for project entry points
Only 10 entry points
appeared to comply with
HTML standards, with 32
entry points failing to
comply

No fewer than 22 entry
points do not have a DTD.
Of those that do, HTML 4 is
the most popular (used in
14 cases) followed by
XHTML 1 (6 cases) and
HTML 3.2 (1 case)
Comments
In order for HTML resources to be processed by
automated tools, it is highly desirable that the HTML
type is documented.
XHTML resources are more easily repurposed.

Compliance with
Accessibility Guidelines
The Bobby accessibility testing tool was
used to analyse compliance with W3C WAI
guidelines for project entry points

Discussion
It should be noted that the Bobby accessibility
testing tool was used to analyse only accessibility
aspects which could be identified by automated
tools.
A more thorough accessibility survey would require
manual analysis in order to identify problem areas
which automated tools would not detect.

Projects And The
Internet Archive
The Internet Archive can provide historical
access to Web sites.

2 Web sites ban robots from accessing the site.
Discussion
Although project Web sites often provide valuable
information about the project (including access to
project deliverables, publications, etc.) Web sites
can disappear after project funding finishes.
If a project Web site disappears the Internet
Archive may provide access to useful resources.
In addition if a Web site is available in the Internet
Archive this indicates that the Web site is
accessible to robot software.

Project 404 Error Pages
404 error pages can be an important
navigational feature for Web sites.
Findings
14 Web sites have tailored
their 404 error message.
28 Web sites use the
server default error
message.

contains the project’s

Additional Features
Additional features for 404 pages include:
● Access to search facilities
● Context-sensitive information

Web Server Technologies
HTTP headers were analysed in order to
profile the server technologies used.
Web Server Software

37 Web sites made use of
the Apache Web server
and 4 used Microsoft’s IIS
server.

Web Server Version
33 Web sites used
Apache v 1.3, four used
Apache v4, two used IIS
v 4 and two used IIS v5.
Further surveys will aim to profile technologies
such as scripting environments.
This information will be useful in certain cases
when establishing the requirements for
deploying projects into a service environment.

Discussion
The survey tools may
provide incomplete
information or the
findings may need
careful interpretation
Some Web sites provide
access to deliverables,
others are the deliverable
while others are intended for
intra-project communications
Limitations of
survey tools
Relevance
to projects
Discussion
Of Surveys
Completeness
of surveys
The surveys only cover
a very limited area of
project Web sites
Use of third-party
Web tools
The surveys make use of
third-party Web sites
which may disappear or
change their terms of use
