Wandora's YouTube extractor is deprecated since Google upgraded the YouTube API. Out long term plan is to rebuild Wandora's YouTube extractor to support current YouTube API version.

Wandora's YouTube extractor reads YouTube video feeds and converts feed data to a topic map. YouTube extractor starts in Wandora with menu option File > Extract > Media > YouTube video feed.... Valid YouTube username and password is required for extraction. Given username and password are not stored between Wandora use sessions. Wandora or Wandora authors have no rights to use any content extracted from YouTube. Also Wandora or Wandora authors can not give you any rights to use any content extracted from YouTube. Respect YouTube's content creator's copyrights.

Video feeds derived from context topics

After first extraction you might want to continue extraction using data already extracted. For example you may have extracted interesting keyword and would like to know what videos share the keyword. Wandora's YouTube extractor can use current topic selection as a source of video feeds. Available options are

  • User has selected topics and would like to extract using subject locator URLs. Each subject locator is considered as a video feed URL.
  • User has selected topics and would like to extract using subject identifier URLs. This option assumes every subject identifier is a video feed URL.
  • User has selected topics and would like to extract using selected topics. This option assumes selected topics are
    • YouTube categories,
    • YouTube users, or
    • YouTube keywords.

Extraction recognizes topic type and starts extraction if valid topic type was found.

As alyankovic topic is in context the expected video feed should contain videos that YouTube user alyankovic has uploaded to the service. Image below views Wandora after successful context extraction. Note the number of YouTube video-author associations has increased. Now Wandora contains all videos uploaded by user alyankovic.

YouTube extraction notes

  • Extraction doesn't make local copies of videos and thumbnails. They still locate in YouTube. Only URLs referring media content is included into the topic map.
  • You can't watch YouTube videos with Wandora application as Wandora has no video player. However, some videos may work if topic map is browsed with WWW browser using Wandora's Embedded HTTP server.
  • Wandora can not be used to upload videos to YouTube. Neither Wandora modifies data stored in YouTube.
