RSS what is the good and bad points asking

[Hellfighter]

has any one ever try RSS for software or a program at all?

what i understand is you can use it add-in to a item to do something like link it to a site, but i am new to this RSS? is it good to learn?
===========================================

this is what i read about it:

Introducing RSS
Think about all of the information that you access on the Web on a day-to-day basis; news headlines, search results, "What's New", job vacancies, and so forth. A large amount of this content can be thought of as a list; although it probably isn't in HTML <li> elements, the information is list-oriented.

Most people need to track a number of these lists, but it becomes difficult once there are more than a handful of sources. This is because they have to go to each page, load it, remember how it's formatted, and find where they last left off in the list.

RSS is an XML-based format that allows the syndication of lists of hyperlinks, along with other information, or metadata, that helps viewers decide whether they want to follow the link.

RSS allows peoples' computers to fetch and understand the information, so that all of the lists they're interested in can be tracked and personalized for them. It is a format that's intended for use by computers on behalf of people, rather than being directly presented to them (like HTML).

To enable this, a Web site will make an RSS feed, or channel, available, just like any other file or resource on the server. Once a feed is available, computers can regularly fetch the file to get the most recent items on the list. Most often, people will do this with an aggregator, a program that manages a number of lists and presents them in a single interface.

RSS can also be used for other kinds of list-oriented information, such as syndicating the content itself (often weblogs) along with the links. However, this tutorial focuses on the use of RSS for syndication of links.

What's in a RSS feed?
A feed contains a list of items, each of which is identified by a link. Each item can have any amount of metadata associated with it.

The most basic metadata supported by RSS includes a title for the link and a description of it; when syndicating news headlines, these fields might be used for the story title and the first paragraph or a summary, for example. For example, an simple item might look like;

<item>
<title>Earth Invaded</title>
<link>http://news.example.com/2004/12/17/invasion</link>
<description>The earth was attacked by an invasion fleet
from halfway across the galaxy; luckily, a fatal
miscalculation of scale resulted in the entire armada
being eaten by a small dog.</description>
</item>
Additionally, the feed itself can have metadata associated with it, so that it can be given a title (e.g., "Bob's news headlines"), description, and other fields like publisher and copyright terms.

For an idea of what full feeds look like, see 'RSS Versions and Modules'.

How do people use feeds?
Aggregators are the most common use of RSS feeds, and there are several types. Web aggregators (sometimes called portals) make this view available in a Web page; my Yahoo is a well-known example of this. Aggregators have also been integrated into e-mail clients, users' desktops, or standalone, dedicated software. See 'Aggregators and other RSS Clients' for more information.

Aggregators can offer a variety of special features, including combining several related feeds into a single view, hiding items that the viewer has already seen, and categorizing feeds and items.

Other uses of RSS feeds include site tracking by search engines and other software; because the feed is machine-readable, the search software doesn't have to figure out which parts of the site are important and which parts are just the navigation and presentation. You may also choose to allow people to republish your feeds on their Web sites, giving them the ability to represent your content as they require.

Why should I make an RSS feed available?
Your viewers will thank you, and there will be more of them, because RSS allows them to see your site without going out of their way to visit it.

While this seems bad at first glance, it actually improves your site's visibility; by making it easier for your users to keep up with your site - allowing them to see it the way they want to - it's more likely that they'll know when something that interests them is available on your site.

For example, imagine that your company announces a new product or feature every month or two. Without a feed, your viewers have to remember to come to your site and see if they find anything new - if they have time. If you provide a feed for them, they can point their aggregator or other software at it, and it will give them a link and a description of developments at your site almost as soon as they happen.

News is similar; because there are so many sources of news on the Internet, most of your viewers won't come to your site every day. By providing an RSS feed, you are in front of them constantly, improving the chances that they'll click through to an article that catches their eye.

But isn't that giving away my content?
No! You still retain copyright on your content if you wish to.

By supplying an RSS feed, you can control what information is syndicated in the feed, whether it's a full article or just a teaser. Your content can still be protected by your current access control mechanisms; only the links and metadata are distributed. You can also protect the RSS feed itself with SSL encryption and HTTP username/password authentication too, if you'd like.

In many ways, RSS is similar to the subscription newsletters that many sites offer to keep viewers up-to-date. The big difference is that they don't have to supply an e-mail address, lowering the barrier of privacy concerns, while still giving you a direct channel to your viewers. Also, they get to see the content in the manner that's most convenient to them, which means that you get more eyes looking at your content.

Choosing Content for RSS Feeds
Any list-oriented information on your site that your viewers might be interested in tracking or reusing is a good candidate for an RSS feed. This can encompass news headlines and press releases, job listings, conference calendars and rankings (like 'top 10' lists).

For example;

News & Announcements - headlines, notices and any list of announcements that are added to over time
Document listings - lists of added or changed pages, so that people don't need to constantly check for different content
Bookmarks and other external links - while most people use RSS for sharing links from their own sites, it's a natural fit for sharing lists of external links
Calendars - listings of past or upcoming events, deadlines or holidays
Mailing lists - to compliment a Web-based archive of public or private e-mail lists
Search results - to let people track changing or new results to their searches
Databases - job listings, software releases, etc.
While it's a good start to have a 'master feed' for your site that lists recent news and events, don't stop there. Generally, each area of your site that features a changing list of information should have a corresponding feed; this allows viewers to precisely target their interests.

For example, if your news site has pages for World news, national news, local news, business, sports, etc., there should be a feed for each of these sections.

If your site offers a personalized view of data (e.g., people can choose categories of information that will show up on their home page), offer this as a feed, so that the viewers' Web pages match the content of their feeds.

A great example of this is Apple's iTunes Music Store RSS feed generator; you can customize it based on your preferences, and the views it allows match those provided in the Music Store itself.

Finally, remember that feeds are just as - if not more - useful on an Intranet as they are on the Internet. RSS can be a powerful tool for sharing and integrating information inside a company.

Publishing RSS
There are a number of ways to generate a feed from your content. First of all, explore your content management system - it might already have an option to generate an RSS feed.

If that option isn't available, you have a number of choices;

Self-scraping - The easiest way to publish a feed from existing content. Scraping tools fetch your Web page and pull out the relevant parts for the feed, so that you don't have to change your publishing system. Some use regular expressions or XPath expressions, while others require you to mark up your page with minimal hints (usually using <div> or <span> tags) that help it decide what should be put into the feed.
Feed integration - If your site is dynamically generated (using languages like Perl, Python or PHP), it may have a RSS library available, so that you can integrate the feed into your publishing process.
Starting with the feed - Alternatively, you can manage the list-oriented parts of your content in the RSS feed itself, and generate your Web pages (as well as other content, like e-mail lists) from the feed. This has the advantage of always having the correct information in the feed, and tools like XSLT make this option easy, especially if you're starting from scratch.
Third party scraping - If none of these options work for you, some people on the Web will scrape your site for you and make the feed available. Be warned, however, that this is never as reliable or accurate as doing it yourself, because they don't know the details of your content or your system. Also, using third parties introduces another point of failure in the delivery process; problems there (network, server or business) will cause your feed to be unavailable.

[General Nuisance]

i have never used rss.. dont even know what rss stands for.. i know it has something to do with live news feeds but other than that i have no idea....

thats one thing i haven't ventured into with pc's yet...

[Rampage.]

its a version of XML that is used to syndicate news and headlines, it was originally made for netscape, then spreaded

[JonM]

depends...if you visit a certain site for just the news, you could get RSS feeds and then not visit the site unless a RSS feed looked nice. I know some RSS, i don't think it's special
