The Digital Age

Statement of Purpose

The purpose of The Digital Age project is to make peoples' lives simpler and more enjoyable by simplifying access to quality digital content, anywhere and everywhere.

Several specific requirements arise:

• handle a broad spectrum of digital content
• quantify the ratings of digital content to a meaningful level, accounting for different personal taste
• maintain content in a central collection
• allow access to content from everywhere via a wide range of clients
• design clients based on client constraints (bandwidth, ui size, etc.)
• every client must always provide ability to rate content
• allow for introduction of new content with the greatest possible signal-to-noise ratio
• allow for safe removal of poorly-rated content

Competition and alternatives include: itunes exaile orb mediamonkey amarok last.fm pandora

Components

• The Digital Age: Server a server exposing a web services XML API to access the metadata (derived from ampache or MythShare) - the server also streams the media
• The Digital Age: Repository a central repository of media and corresponding metadata (mysql)
• clients:
  • The Digital Age: Desktop Clients a desktop client player (port hangthedj to qt, for pc/mac/linux) (also see amarok, sparklemedia, winamp, etc.)
  • The Digital Age: Mediacenter Client a mediacenter player (mythmusic extended (previously known as MythDJ))
  • The Digital Age: Mobile Apps a mobile client player (tons of work being done - iphone - see iAmpache or this, android, palm webOS, blog)

The Roadmap

• The Digital Age Software Manifesto
• Metadata design
  • hasn't metadata structure already been designed and data collected? precanned music companies have this nailed down, I'm sure...
  • what about the last.fm API?
  • see current HTDJ db schema
    • DJ's
    • song ratings by DJ
    • current playlist
  • other ratings (movies, games, books)
• Metadata access
  • Everything stored in a mysql database
  • Available via web service XML API (extended Ampache)
• The Philanthropy Engine

               boost::serialization 
               binary
               XML?  yuck

       Thick client

           cross-platform:
               mythweb + flex player                
           
           windows:

           linux:
               mythfrontend

           palm:

       Server options:
                                           
           Apache + custom mod             C++/boost, may be ugly to develop?
           EHS + STDJ                      C++/boost, far along, not robust/scalable?
           Apache + custom php             PHP, clean, lots of work? 
           Apache + custom MythTV          PHP, have to ramp up, prolly needs MythShare
           Apache + custom Ampache         PHP, Fat-client support difficult?

       PC client options:

           Mythfrontend (linux)            C++, MythShare plugin, fun!  Need MythWeb support for http.
           HTDJ (windoze)                  Far along, needs good HTTP client
           Browser + embedded player       Is flex mediaplayer ready?
           Browser + OS

       Palm client options:

           TCPMP + Blazer
           Custom TCPMP

       ===============================

       I am leaning towards:

           linux server
               Mythbackend
               Apache + MythWeb + MythDJ (use MDS?)

           linux client
               Mythfrontend/MythDJ

           windows client
               MythWeb/MythDJ + HTDJ

           palm
               Blazer + MythWeb/MythDJ download
               TCPMP playback
               SD card preload from MythWeb/MythDJ

           friend
               MythWeb/MythDJ + OS (VLC, etc.)
               MythWeb/MythDJ + embedded flash/flex2?
