Project Technical Specs
© 2005 R. Sheranian

1. Flash Structure:
   · Flash MX 2004
   · 1 swf file
   · 2 scenes, one for the archive and one for the credits
   · The photos, titles, video controls, and transcript box are all embedded in Flash
   · The videos and transcripts are stored externally and loaded into flash using Action Script to call the files through XML.
   
   
2. Videos:
   · stored externally
   · .flv files. (There are also .mov files in the folder although these were only used to create the .flv files and are not necessary for the project to run)
   · All the videos are stored in a local folder called video.
   
   
3. Text Files (transcripts):
   · The transcripts are all created as text files with Unicode encoding and are stored in a local folder called transcript.
   
   
4. XML
   · encoding = [?xml version="1.0" encoding="iso-8859-1"?]?
   · xml structure (all tags are represented by bracets because opencourse will not display html tags also code does not keep correct format in opencourse)
   [interviews]?
   [interviews name = "crane"]?
   [transcript]? transcript / transcript_name.txt [/transcript]?
   [video]? video/video_name.flv [/video]?
   [/interviews]?
   [/interviews]?
   
   
5. Action Script
   · 2.0
   · code (note: code does not keep correct format in opencourse)
   //load xml with:
   xmlData = new XML();
   xmlData.ignoreWhite = true;
   xmlData.onLoad = loaded;
   xmlData.load("name_of_doc.xml");
   //create function to load text from xml
   getTranscript = function (myTranscript) {
   theTranscript = new LoadVars?();
   theTranscript.datastring = "";
   theTranscript.onLoad = function(success) {
   if (success) {
   // what to do with the data
   transcript_txt.text = theTranscript.datastring;
   //create function for video connection
   var nc = new NetConnection?();
   nc.connect(null);
   var ns = new NetStream?(nc);
   videoCon.attachVideo(ns);
   

//inside buttons call data from xml
comments /(comments are the transcripts)/= xmlData.firstChild.childNodes[1]?.childNodes[0]?.firstChild.nodeValue;
video = xmlData.firstChild.childNodes[1]?.childNodes[1]?.firstChild.nodeValue;

1. Scalability:
   This project can easily be scaled. Add new video and transcripts and then add a node to the xml doc and in actionscript add the node to the script inside the new button.
