Harnessing Free Content with Web Service APIs Harnessing Free Content with Web Service APIs Presentation Transcript

  • print $title; print $subtitle; print $author; print $position; print $institution; $title = “harnessing free content with web service apis”; $subtitle = “an ala editions workshop”; $author = “jason paul michel”; $position = “user experience librarian”; $institution = “miami university libraries”;
  • agenda • Discuss open web ecosystem • Place of APIs in that ecosystem • What is exactly is an API? • An example from the programmer’s perspective • Real World examples • Slice of available APIs • What is needed for development • Where to find and keep up with information
  • the “open” web ecosystem • social web services are not social merely because of the interactions between users they facilitate. • social web services are social because they also are able to talk to one another on a programmatic level.
  • the “open” web ecosystem • thus, If This Then That (ifttt.com)
  • the “open” web ecosystem • thus,
  • the “open” web ecosystem • Achieved largely through the use of APIs • API = Application Programming Interface • Method of data transfer via HTTP
  • neighbor’s garage analogy Open Source: take whatever you want, modify however you want, use however you want Proprietary: pay for each tool in the garage, use them as designed API: utilize the services of the garage, if you have authorization and ask the right way
  • Why APIs? • Increase visibility of data / service • Take advantage of the crowdsourcing model to improve service, e.g. Tweetdeck • From libraries’ perspective: its important to integrate with wider web environment
  • Typical API Process • Request API Key from Service • Choose scripting language: PHP, Ruby on Rails etc. • Using chosen language, submit data request via available API methods • Ingest that data in JSON, XML or other data type • Transform the data to make it usable with scripting language • Upload data to a database • Wrap data in HTML, CSS for user interface
  • api request example https://api.twitter.com/1.1/search/tweet.json?q=book%20OR%20research Base url Each Web Service typically has several base urls depending on the type of information you are seeking and each resource type has its own set of parameters, e.g.: https://api.twitter.com/1.1/followers/ids, https://api.twitter.com/1.1/friendships/lookup Data type Parameters
  • api request example [statuses] => Array ( [0] => stdClass Object ( [metadata] => stdClass Object ( [result_type] => recent [iso_language_code] => en ) [created_at] => Sat Jul 20 16:25:22 +0000 2013 [id] => 3.58623679498E+17 [id_str] => 358623679497777153 [text] => This book just got too good! She said yes!! 👏 👏 #christiangrey [source] => Twitter for iPhone [truncated] => [in_reply_to_status_id] => [in_reply_to_status_id_str] => [in_reply_to_user_id] => [in_reply_to_user_id_str] => [in_reply_to_screen_name] => [user] => stdClass Object ( [id] => 307066025 [id_str] => 307066025 [name] => Alicia Reece [screen_name] => aaliciaaaajo [location] => etc…..
  • api request example • At this point you can send the data received to a database or create a dynamic web application on top of the live data.
  • try it • https://graph.facebook.com/username or • https://graph.facebook.com/pageid
  • working examples
  • twitter • Programmatically capture, store & display potentially relevant tweets in specific geolocation to serve as a springboard for proactive info services and social interaction. https://api.twitter.com/1.1/search/tweet.json?q=book%20OR%20research&geocode=39.5069974,-8 working examples
