 Hello and welcome to this video lecture on RSS. So in this video lecture, we shall be looking at the basics of RSS. What is RSS technology as in XML and how do we use RSS technology and its advantages. So these are the learning outcomes for today's video lecture. We shall learn the basics of RSS and use and manage RSS reader that is feedly.com a free available and usable RSS reader to subscribe to various RSS feeds. So these are the contents of today's video lecture introduction to syndication and RSS technology RSS architecture. How is the technology working and its nature then reader configuration and getting updates from feeds. I shall be showing you a live demonstration as of as of how to subscribe to RSS feeds and concluding with the references and acknowledgements. So basically what is RSS stands for really simple syndication. So you might have come across this symbol while you might be browsing through many internet sites. So this symbol indicates the technology of RSS or it also stands for rich site summary. So syndication basically means gathering of information from various sites of individuals interest. So a particular individual might be interested in say for example sports or sports news updates. So in sports he might be only specifically interested in say for example soccer news. So RSS is a technology to deliver real time updates on newer information available to the user. So any time a website updates itself or the website is updated with a newer content and the user is interested in that particular content. So the RSS feed will get updated and the user will be able to see that update on its screen because of the RSS. So RSS is this updation mechanism which updates which gets updated and keeps the user updated with the current or real time updates. So the choice of the topics that the user needs to be updated or user defined the user can define. So he does not need to get all the news say for example here he has subscribed to some news if he wants a particular news so he does not need to go through all the news but he can just subscribe to that particular RSS feed and then he will get the particular news from the particular channel about a particular sport that he might be needing or news about a particular event that happened say for example a particular catastrophe that has occurred in some area of some country or a continent so he can just subscribe to that particular news and get its updates whenever update is made on a particular website. So there are two parts of this RSS technology one is the RSS feeder and an RSS reader. So the website that the user wants to keep on checking or had to earlier keep on checking develops or has this RSS feeder and the user side has the RSS reader. So the RSS feeder is a web feed that allows to access contents and updates that is at the website side of the website and the next is the RSS reader also known as the aggregator which reads all the real time updates only from the website that the user prefers to and the current RSS version is 2.0. So this was the basic introduction to RSS technology. So how does this RSS work? Every website that the user is interested has an RSS XML file which gets updated and it is stored on the web server. So these are the websites there are n number of websites that the user might be interested in and these are the website which the user desires the updates from it might be news channels it might be podcasts and so on. So these XML files are regularly updated as any update happens at the site website and as these XML files are updated the reader or the aggregator on the side of the user is checked checks for the real time updates like breaking news and so on and anytime an update happens it the aggregator immediately reads it and the information is updated on the web browser that is the web page or the blogger wherever the user is using the aggregator. So basically the aggregator gets updated and the user who is interested in the news who is interested in the latest updates is gets updated. So the user side side is updated through the XML file which is updated at the website. So this is a basic description short description of how RSS technology actually works. This is an example of the RSS file basically RSS is an RSS file is an XML file. So we start with the XML definition showing that this is an XML file and then tag it with an RSS tag and its version 2.0 showing that this is an RSS file and these tags excuse me that you see here are the predefined tags and they are mandatory tags which go in the RSS file. There are also some tags which are not mandatory like publication date and so on but we shall look at the mandatory tag. So the title link and the description are the tags that come here. So the channel is the channel from where we have subscribed the site. The title states for the title of the channel and the site. The link is the link URL where we can find the website. The description is a short description about the same about what news or what particular updates is the link giving us and so on. And it goes on just like that. So title link and description are the tags which are defined when in an RSS file and then at the end we close with the channel tag which we had begun with and concluding with an RSS tag. I shall not describe this file completely here but I shall take it in another video lecture. So this is a reflective spot which of the following provide RSS reader services. So pause the video and answer this question. You are free to use the internet to answer to go across and answer this question. So if you have gone through and browse the internet to search that which of the following provides the reader services. If you have carefully seen all the four services are online services which provide for aggregator services. So feed reader flow reader and blog loving are all four services which provide reader services RSS reader services. So I shall quickly show you how we can configure and subscribe for RSS feeds on feedly.com for getting real time updates from different website. So firstly you need to log log in to feedly.com. You log into that website and create you can create your account. You can also log in through your Google account if you have one. I am going to log in with my Google account to show you how an aggregator works at your site at your site. Excuse me. So these are my feeds I have created a feed I want the news to be updated at my site. So these are the feeds and my news is the name of my feed. So all these news that I am able to see here are from different sites. One is from BBC news. The other is from India news. The other is from India TV and so on. So now I am going to add some more content. I want to see some sports news at my site. So I am going to add on click content and I am going to search for say for example Sky Sports. So Sky Sports news is available here and as you see if you are interested if you are a Manu fan you can subscribe for the Manu feeds. If you are an Arsenal fan you can do so but I am just going to click on Sky Sports news and I am going to follow it. So it will ask me that should it add it to my news or a new feed. So I am going to click on new feed and I am going to add it as sports news. So sports news will be a different feed which will give me just sports news and so on. So in this feed I shall only go through the sports news. I shall not have some different news here but I will follow only sports news here. Similarly say for example if I am also interested in BBC sports football so I can just click there and if I click on follow it will ask me the feed that I want to add BBC sports football to and I will click on sports news and so on. So it will start getting the updates from this website as well. I need not to go to that particular site to look at the news but I can just see it on my particular page single page. So there is this website Times of India that I have logged into this is the URL of that RSS feeds timesofindia.indiatimes.com slash rss.cms where I get all the RSS that I want to from top stories to most recent stories India, world and so on. Say for example sports. So I want these sports also from India Times to be included on my aggregator site. So I am going to right click here and copy the link address and I am going to also add content and I am going to paste the link here and it will show me that this is the feed sports news cricket news latest updates on tennis football and so on and I am going to select it and I am going to follow it and which will be added to my sports news feed and add. So right now it is showing me that I am following the sports news from India Times and once I go to sports news if you see carefully so this is the news that has been added from India Times.com so whichever website you are interested in you can add the RSS feed from that particular website and that update on that site will be immediately reflected on your website. So this is how you use feedly.com RSS reader to read the updates from all the sites of interest. So coming back to this was the configuration and getting updates from feedly.com so these are the references and acknowledgments that I have used for today's video lecture. Thank you.
