I've recently joined the QA IG mailing list and have a question. There is a need for standard definitions for We resources and Web usage. This includes terms such as (for Web usage) "visits", "users", "unique users" and "sessions" (for Web resources) "Web page" and "page size". Definitions are needed in order that different applications (such as Web log server analysis packages and Web auditing applications) will give consistent and reproducible results. As an example the Web accessibility tool Bobby and the NetMechanic Web analysis services have different ways of measuring the size of a Web page (Bobby only looks at the HTML file and images, whereas NetMechanic looks at external CSS and JavaScript files). Also these two applications treat the robot exclusion protocol - REP -differently (NetMechanic obeys it, and doesn't include the file size of any resources which the REP stops it from looking at). In addition there is no agreed way of handled negotiated content (file formats, languages, page refresh and redirect) or frames. There is a need for standard definitions to support W3C's WAI Evaluation work (file size affects accessibility ). Languages such as EARL will need this in order to record more objective summaries. W3C did do some work in this area some time ago, as part of the Web Characterisation activity - but this work stopped some time ago. I am aware of two communities which appear to be addressing such standardisation of terms: the Web Advertising Community and the Web Auditing Community. However their definitions appear to be different ("a session is use from the same IP address within a 30 minute period" versus "a session finishes when a user leaves the Web site and visits another one"). In addition these communities are probably not as aware of the implications of new W3C technologies as members of this list and don't appear to have addressed content negotiation issues. Would addressing this issue be within the scope of the QA activity? I guess the "Coordination with External Groups" would support dialogue with the Web Advertising and the Web Auditing Community standardisation work. Thanks Brian PS are any members of this list going to the W3C AC meeting in Nice next month? --------------------------------------- Brian Kelly UK Web Focus UKOLN University of Bath BATH BA2 7AY Email: B.Kelly@ukoln.ac.uk Web: http://www.ukoln.ac.uk/ Phone: 01225 323943
