The Use of RSS and Aggregators

Really Simple Syndication (RSS) is a tool useful for saving or retaining updated information on websites that you visit a lot or websites that are your favourite. RSS uses an XML code which scans continuously the content or subject matter of a certain website in search of updated information then sends the information by way of feeding the information to your subscribers.
RSS feeds are generally being used in blogs or news sites, though any website wanting to broadcast and publish information can use them. Once new information is sent, it will contain a headline, a little bit of text, and either a rundown or a brief review of the news or story. The user will need to click the RSS feed link to read further.
To accept RSS feeds, a feed reader is needed. This is called a feed aggregator. Aggregators are freely available online, and all that is needed is a little searching. You will be able to find a certain interface that best suits you. What’s more, RSS feeds can also be read and retrieved from mobile phones and on Personal Digital Assistants(PDAs.
Once you stumble across a website that you want to insert into the aggregator, the process can be done in two ways. Almost all sites offering an RSS feed will display an “RSS” or “XML” logo in their pages and with one click, it promptly adds that particular feed to your aggregator. Some aggregators however, need you to copy and then paste the URL of the feed into the program.
Whatever the method used, you can be certain that the feed will be accessible as soon as you have inserted it, likewise, in a matter of seconds, the next update may arrive. If you no longer want to receive updates from a particular site, you may simply delete the feed from the aggregator.
Through e-mail subscriptions, you can receive newsletters. RSS feeds on the other hand, can be more convenient in keeping up with newsletter updates since they are prompt and available in an instant; you no longer have to wait for a scheduled time to obtain a news summary. Plus, the news is never detained by a spam filter.
RSS feeds are widely used every day by individuals who understand and appreciate the accessibility of fast reports and news that can be readily read and they generally only read updates that they find interesting.
Aggregators
Aggregators are popular in the use of feeds, and come in many varieties. Web aggregators or portals as they are sometimes called, create this view which is made available in a web page. Nowadays, aggregators have been incorporated into e-mail programs, and other forms of standalone software.
Aggregators offer a whole host of special features, such as combining more related feeds in just a single view, hiding certain entries or statements that have already been read, and classifying entries and feeds, into specific categories.
Why make a feed available?
Your site visitors can receive your content without even having to visit your web pages. While at first, it may seem corrupt, it will in fact enhance the visibility of your site. This is because subscribers can easily keep track with your site, allowing them to view it any time they want to, whether on the train, in the dentists waiting room or at the office. Also, RSS feeds keeps your site in the mind of your subscribers, as they get updates each time you update your site.
As an example, every week your website broadcasts a new feature. Having no feed, your viewers will have to remember to go to your site to see if they discover something new. That is, if they remember to and they have the time. However, if you supply a feed for your viewers, they can just point to their aggregator and it will immediately provide them with a link and a summary of updates at your site.
Which format is best?
Syndication can be very confusing as it uses a lot of formats. However, this can be easily remedied as in general, syndicated libraries are used by aggregators which conceptualize a particular format that a feed is in, in order that they can utilize a certain syndication feed.
With this knowledge, the format is just a matter of personal taste. RSS 1.0 is wide spread, and practical should it be utilized in Semantic Web Systems. RSS 2.0 is very easy to create by hand and Atom is an IETF Standard, which brings consistency, stability and an accepted community to support its usage.
