OBSERVATION - EXPANSION OF THE INFORMATION TECHNOLOGY - RECENT RECORDS REVEALED MORE THAN TWENTY (20) BILLIONS OF WEBSITES - USER WILL NEED MONTHS EVEN YEARS OF BROWSING TO COVER THE COUNTLESS WEB PAGES THAT MAY BE AVAILABLE SOLUTION - CREATION OF RSS RSS IS AN APPLICATION IN XML FILE FORMAT THAT OFFERS WEB USERS THE POSSIBILITY TO KEEP TRACK OF THEIR FAVOURITE WEBSITES FOR A SMOOTH BROWSING. ESPECIALLY UP-TO-DATE WEB PAGES AT A GLANCE, WITHOUT NECESSARILY STEPPING INTO THE RELEVANT WEBSITES. INTRODUCTION

STANDING FOR REALLY SIMPLE SYNDICATION, A RSS FEED IS A COMPUTING TECHNOLOGY USING THE 1.0 VERSION OF XML (EXTENSIBLE MARK-UP LANGUAGE) FORMAT. RSS HELPS BROWSERS SORT WEB CONTENTS THEY WISH TO INTERACT WITH; WHICH CONTENTS ARE IN GENERAL AUTOMATICALLY GENERATED PROVIDED UPDATES ARE AVAILABLE. RSS FEED IS ALSO A POWERFUL TOOL TO WEBMASTERS TO SYNDICATE (CLUSTER) NUMBER OF OTHER WEBSITES LINKS ON THEIR WEBSITES FOR AN EASY BROWSE OF USERS ACCORDING TO THEIR INTEREST. SO, RSS FEED CAN BE REGARDED AS THE WEB-ON-DEMAND. GENERALLY, RSS FEED ARE USED BY SITES MANAGING BLOGS, NEWS, DOWNLOADS. WHAT IS RSS?

- March 1999: NETSCAPE created RSS 0.90 (RDF - Resource Description Framework- SITE SUMMARY) - July 2000: upgrade to RSS 0.91 (Rich Site Summary) by DAN Libby with (USERLAND), a simple version of xml (no more RDF specification) - April 2001: RSS 1.0 by Aaron Hillel SWARTZ based on RDF then September 2002 RSS 3.0 (not xml format) - September 2002: Dave WINER launches RSS 2.0 at Harvard University then RSS 2.01 in November 2002 Note: RSS 0.91 has been upgraded to various versions namely 0.92, 0.93, 0.94 RSS, QUICK HISTORY

HISTORY MAP OF RSS figure 2.1 RSS, QUICK HISTORY

- ON A WEBSITE YOU CAN IDENTIFY RSS WITH THESE ICONS SUGGESTED BY MOZILLA AND VALIDATED BY RSS BOARD - SOME WEBMASTERS MAY USE THE FOLLOWING ICONS figure 2.2 CARACTERISTICS OF RSS

In a practical way, a RSS FEED is a hyperlink made up of three important parts: the URL of the site, the TITLE and a SHORT SUMMARY of the topic it refers to. a- The Channel Tag Syntactically, the main component of RSS FEED is the channel tag along with a set of properties that are also tags. 1- Compulsory properties - Title tag: refers to the name given to the channel serving as reference to browsers - Link tag: is the URL address of the website the feed serves - Description tag: a short comment on the related topic - At least one Item tag: specifies the contents of the feed. Item tag also includes sub tags such as title, URL, description, PUBDATE etc. CARACTERISTICS OF RSS

2- Optional Properties - Language tag: setting the language in which feed contents the be generated - Webmaster tag: providing few informations on the webmaster - Pubdate tag: that displays the date of the last publication for the content - Docs tag: is the link of the website that refers to the files or to specification on the format used (Harvard specification) CARACTERISTICS OF RSS

a- Header File Any RSS FEED starts with the XML and RSS TAGS that specify their version. sample coding <?xml version=”1.0” ?> <rss version=”2.0”> <channel> ….. </channel> </rss> SYNTAX OF RSS SOURCE CODE

b- Syntax of Channel Tag and its Properties <channel> <title> MY_RSS_FEED_HEADLINE </title> <link> http://innovation2013unicam.wikispaces.com </link> <description> This is the wiki for unicam2013/2014 computer science Master students…</description> <item> … </item> < language> en-gb </language> <pubdate> sun, 26 jan 2013 </pubdate> </channel> SYNTAX OF RSS SOURCE CODE

A- Web Browsers Almost all recent browsers incorporate RSS FEEDS reader on their interface - Internet Explorer7 and Later Versions - Displays RSS icon on the toolbar. - When a site runs RSS FEED, Internet Explorer highlights the RSS icon figure5.1: WEBSITE WITHOUT RSS FEED HOW TO ACCESS RSS FEED

figure5.2: WEBSITE WITH RSS FEED HOW TO ACCESS RSS FEED

- To read a feed, user click on the feed icon button on the toolbar to select desired feeds (if the website offers many feeds) - Then select “subscribe to this feed” button - Make desired set up (create/select folder, rename, add to favourite bar), - Then click on subscribe. The feed is saved in the favourite centre. figure 5.3: SAVING OF RSS FEED HOW TO ACCESS RSS FEEDS

- Firefox - Safari - Opera b- Online Facilities - Netvibes - Mon Yahoo! - Iwake - Sys Monitor - Pretty RSS c- Aggregators - Rssowl - Feedreader - Vienna - Netnewswire - Bloglines HOW TO ACCESS RSS FEEDS

a- Webmaster A webmaster can include RSS FEED to its websites to: - Ease the browsing of his users - Keep in touch with its public - Customize its contents with respect to the topics discussed in the website - Make advertisement for other websites b- End-user Any web user can access feeds to: - Organize his web usage timing - Focus only on topic of his interest - Control the daily updates of his favourite websites etc. User is prompted to a simplified web page consisting of a set of links, that contains a TITLE, a URL and a DESCRIPTION of the related topic. WHO CAN ACCESS

figure 7.5 USAGE OF RSS, SOME FIGURES

a- RSS, Survival Or Decline? - INTRODUCTION OF RSS INCREASES BROWSING ACTIVITY - INCREASE OF COMPANY SELLING. ACCORDING TO MARKETINGSHERPA, 75 MILLION CONSUMERS AND BUSINESS PEOPLE IN USAAND UK USE RSS REGULARLY - RSS PROVIDES UNIQUE NEWS AUTOMATICALLY TO ANY USERS - OFFERS THE ABILITY TO DISPLAY LATEST NEWS OF A WEBSITE ON SOCIAL NETWORKS DIRECTLY - ENABLES CUSTOMIZED CONTENTS ACCORDING TO THE RECIPIENT: . Facebook users are fans of entertainments. so, it is the best area for kidding materials . On Twitter, we share latest news. so, suitable for exclusivities, latest offers, scoops . The scope of LinkedIn covers jobs offers, services providers - OFFERS POSSIBILITY TO A WEBMASTER TO ACCESS AND SPREAD NEWS FROM OTHER WEBSITES - HIGHLIGHTS A WEBSITE BY SEARCH ENGINES INDEXING PERSONAL OPINION

However, RSS shows some weaknesses: - In a regulation viewpoint, RSS is not a specified format i.e the standard is not approved by any international board like W3C, IANA (Internet Assigned Numbers Authority) - Feeds updates require constant manual interventions of the webmaster - Provides contents that require specific tools to read them - Feeds face bugs issues - Some aggregators are not free - Lost of data. Google has recently killed off the GOOGLE READER destroying users’ data (since July 15, 2013) PERSONAL OPINION

A- RSS, Challengers And Potential Successors 1- ATOM - ATOM IS SPECIFIED (IETF) LANGUAGE CREATED TO OVERCOME RSS UNCONTROLLABLE SPECIFICATION CRISIS - ABLE OF READING FEEDS, IT ALLOWS USERS TO WRITE TO THE WEB 2- E-NEWSLETTER : DOCUMENT THAT INFORMS, ANNOUNCES, REMINDS, ADVISES, INSTRUCTS, ADVERTISES AND COMMUNICATE WITH DELIVERY FREQUENCY, CONTAINS UPCOMING INFORMATIONS 3- PINTEREST: ONLINE CATALOG OF INSPIRATION THAT PROVIDES UPDATES, IDEA, GUIDANCE WHEN WORKING ON A PROJECT 4- PODCAST 5- WIDGET PERSONAL OPINION

TO SUM UP, EVEN THOUGH RSS IS LARGELY USED, IT IS NOT REALLY PERCEIVED BY USERS. MARKETINGSHARPA STATES OUT OF 75 MILLION OF USERS, 50 MILLION REALLY HAVE NO IDEAABOUT THE APPLICATION THIS SITUATION LEADS TO THE FOLLOWING OBSERVATIONS: - LACK OF PROMOTION ON THE APPLICATIONS - APPLICATIONS ARE MOSTLY USED BY PROFESSIONALS OF THE INTENDED FIELD - THEY DISAPPEAR EARLY CONCLUSION
