If, however, some of these ideas strike you as interestingconsider adding them to your project implementation plan.8.13 Exercise 7: Refinement PlanPrepare a plan for how you're going to improve your discussion forumsystem, including any changes to data model, page flow, navigationlinks, page layout, annotation (help text), etc. Place this plan on yourteam server at /doc/planning/YYYYMMDD-discussion (if youXHTML-MP ExampleWe're not in the 1970s anymore.Connection closed by foreign host.The text in bold (above) is what the programmer types, simulating amicrobrowser request. The exchange looks a lot like what we'd seefor a regular HTML browser. The main differences are the inclusionof the XML declaration and document type definition in the first twolines of the document, and the use of the namespace attribute,xmlns, in the opening html tag.A server wishing to distinguish between desktop and mobile userscould search the contents of the HTTP Accept header for the stringapplication/xhtml+xml;profile="http://www.wapforum.org/xhtml", which issupposedly required by the XHTML Mobile Profile specification(http://www1.wapforum.org/tech/documents/WAP-277-XHTMLMP-20011029-a.pdf). By contrast, a desktop browser, if it lists xhtmlamong the formats that it accepts, will generally not refer to themobile profile. Here's what Microsoft Internet Explorer 6.0 supplies asan Accept header:image/gif, image/x-xbitmap, image/jpeg,image/pjpeg, application/vnd.ms-excel,application/vnd.ms-powerpoint, application/msword,application/x-shockwave-flash, */*Mozilla 1.4a (the open-source Netscape Navigator) does promise toaccept xhtml:172177
Protocol (IP) routing, a standard HTTP proxy, or a WAP gateway. Inthe last case, the gateway and phone communicate using a specialset of protocols that, among other things, compresses data beforetransmission over the wireless network. The net effect is that thephone's browser (sometimes called a microbrowser) looks to a publicHTTP server like a standard Web browser issuing HTTP GETs andPOSTs.Content is delivered in"XHTML Mobile Profile", astrict subset of XHTML,which is an XML-conformantversion of HTML. Here's ashell session resulting in thereturn of an XHTML-MPdocument short enough toprint in its entirety:The mobile industry is consumingmarkup languages at a rapid rate. Theprogression has taken us from theHandheld Device Markup Language(HDML; 1997) to the Wireless MarkupLanguage (WML; 1998) to the currentrecommendation, XHTML Mobile Profile(XHTML-MP; 2001). We can take heartfrom the fact that XHTML-MP is derivedfrom XHTML, the World Wide WebConsortion recommendation forstandard browsers. Gone are the badold days when a developer had to learna new markup language, and servershad to be configured to send newContent-Type headers, in order todeliver mobile content. We expect thatXHTML-MP will thereby enjoy wideradoption and greater stability.name files with year-month-day in the beginning, they will sort inorder of creation).8.14 Exercise 8: Client SignoffAsk your client to visit the discussion forum user and admin pages.Ask your client to review your usability test results and refinementplan. This is a good chance to impress your client with the soundnessof your methodology. If your client responds via email, make thatyour answer to this exercise. If your client responds orally, makenotes from that conversation your answer.8.15 Exercise 9: ExecuteAfter consultation with your teaching assistant, execute your plannedimprovements.8.16 Time and MotionOne programmer who has mastered the basics of Web/db scriptingcan usually whip out a basic question-and-answer forum in 8 hours.The team together will need to spend about one hour preparing agood in-class presentation. The team together will generally require 3hours to conduct and write up the user test. Talking to the client andrefining the forum will generally take at least as long as the initialdevelopment effort.XHTML-MP Example Document% telnet philip.greenspun.com 80Trying 216.127.244.134...Connected to philip.greenspun.com.Escape character is '^]'.GET /seia/mobile/ex1.html HTTP/1.0HTTP/1.0 200 OKMIME-Version: 1.0Content-Type: text/html176173
