4.2 Implementation Before starting the implementation of the application an analysis on the APIs ofthe main social networks has been conduced, trying to understand which of themprovided important quantitative information necessary to the realization of theproject, paying also particular attention to the privacy constraints.In order to consider different types of socials networks, the following has beenchosen:ü SlideShare: a social network used to upload and share presentationswith others.Through a valid user account, an API “key/secret” have beenrequested and utilized in order to connect the application to SlideShareand to get users public information (like presentations, contacts,favourites, etc.), available without requests limits.Since the JSlideShare 8 API provided was based on the version 1.0, theoldest one, an upgrade to the new ver. 2.0 has been done in order to getmore information.ü YouTube: a video-sharing network on which users can upload, share,and view videos.After the request of a valid “client id” and “developer key”, the JavaYouTube’s Data API have been used to retrieve YouTube’sinformation (like comments, videos, friendships…) in the form ofGoogle Data API feeds, without requests limits.8 JSlidesShare: is a Java wrapper around the SlideShare API. It can be used for mashing up slidesa Java Web application.48
ü Twitter: a micro blogging social network, enabling its users to sendand read other users' messages, called tweets.Through the request of a “consumer key/secret” associated to the userapplication developer profile, the java Twitter4J API have been used inorder to get users public information (like followers, following, tweets,etc.). Due to the call-rate limitation and to the impossibility to put theapplication into the white-list (that mean no rate limit) detailedinformation (like tweets content, retweets, friendships details…) wasnot considered.ü Facebook: social network intended to connect friends, family, andbusiness associates.In order to get information with the RestFB 9 library, the “APIkey/secret” associated to the application was not sufficient; an accesstoken for each user, released after his authorization, has been used inorder to get all the detailed profiles information.9 RestFB: is a powerful Facebook Graph API and Rest API client written in Java.49
