ABC's of RSS

Implementing RSS (Really Simple Syndication) can be aided by an understanding of the terms relating to RSS. Learn the ABCs of RSS....

A - AutoDiscovery
Auto Discovery is code that is inserted into the header of an HTML web page, which then indicates to readers that an RSS feed is available for the content.

B - Blogs
Blogs are web logs that are updated regularly, usually on a daily basis. Blogs generally contain information related to a specific topic. In some cases, blogs are used as daily diaries about people's personal lives, political views, or even as social commentaries. The truth of the matter is that blogs can be shaped into whatever the author wants them to be. While initially thought of as diaries or online journals, blogs have evolved into the latest fresh web content.

C - Cache
Cache is a temporary storage area for frequently-accessed or recently-accessed data. Having certain data stored in a cache area speeds up the operation of the computer. Using a cache with RSS feeds will help minimize bandwidth and display an RSS feed's content quicker.

D - Display
RSS Many webmasters post the content of an RSS feed on their website. They use either PHP, ASP, or javascript for such purposes. If done properly, the feed's content will dynamically update as the content of the feed changes.

E - Elements
Within an RSS feed, there are various feed elements. The elements of an RSS feed are defined by tags.

F - Filter
Many RSS feeds contain duplicate or similar content. Publishers can filter RSS feeds so that they only see content that they wish to see, by filtering out duplicate postings.

G - GUID
GUID stands for Globally Unique IDentifier. The RSS specification strongly suggests that each RSS feed item have a unique GUID. If you are creating feeds, a GUID is important because GUIDs are often used by feed readers and aggregators to determine if a feed item is new or simply an existing item that has been updated. Each item in the RSS feed should have a unique GUID. H - HTML HTML, which is the acronym for HyperText Markup Language, is frequently used to design websites.

I - iTunes Namespace
The iTunes Namespace allows the user to add the information necessary to have a podcast listed on the Apple iTunes Music Store (ITMS).

J - JavaScript
Javascript can be used to display the content of an RSS feed. K - Keywords Keywords should be integrated into the RSS feed to help search engines determine what the RSS feed is about. L - Links Links are used to direct RSS readers to the original webpage containing information that directly relates to the feed.

M - Mashup
A mashup is a combination of multiple RSS feeds that have been merged together to create a new, single feed.

N - Namespace Extensions
The RSS specification allows you to create and use your own custom elements (tags) in any RSS feed by declaring your own namespace. Doing this is 100% in line with the RSS specification and the feed will validate. However, you should have a specific and well-planned reason to do so. No RSS readers, or other RSS processing applications, will be able to use your custom info for any purpose. Adding elements (tags) would typically be used only in an in-house situation where both the writing application and the reading application have prior knowledge of the new tags.

O - OPML
OPML, or Outline Processor Markup Language, is a file format standard that can be used to exchange subscription lists between programs. OPML is used as a standard to import or export groups of RSS feed subscriptions. OPML was initially designed by Radio UserLand as a file format for outlines. The purpose of this format is to provide a way to exchange information between outliners and Internet services. OPML has since been adopted for other uses, the most common being to exchange lists of RSS feeds between RSS aggregators. OPML is an open format, allowing other services to extend the format. While OPML was not initially designed as a vehicle to share RSS feeds, it has become the de facto standard. OPML, like RSS, is based on RSS, and because of the similarities, those familiar with RSS have embraced OPML as a way to share RSS feed collections

P - Podcasting
Podcasting is online audio content that is delivered via an RSS feed. Many people equate podcasting to "radio on demand". However, in reality, podcasting gives the listener far more options than radio does, in terms of content and programming. In addition, podcast listeners can determine their own time and the place for listening, meaning they decide what programming they want to receive, and when they want to listen to it. Listeners can retain audio archives to listen to later, at their leisure. While blogs have turned many bloggers into journalists, podcasting has the potential to turn podcasters into radio personalities.

Q - Query
Webmasters can create RSS feeds based on search queries for their websites.

R - RSS
RSS is a standard format for syndicating content on the Internet. The content can be anything! Information contained in an RSS feed is often syndicated on other sites, which expands its reach. Website visitors love RSS because they choose which feeds they wish to subscribe to. If at any point they are unhappy with the content contained in the RSS feed, they simply unsubscribe and no longer receive notification of feed updates. RSS is really a win-win for both subscribers and publishers. In order to get a better understanding of how RSS works, download an RSS reader or use a web aggregator and subscribe to an RSS feed (they are usually indicated by a small orange icon).

S - Syndication
Syndication is the supply of material for reuse and integration with other material.

T - Template
Many webmasters use templates to layout the contents of their RSS feed and make it match there website.

U - URL
URLs can be embedded into the description of the RSS feed items, so that when the feed is syndicated, the content originator gains backlinks.

V- Validate
Feed validation is important. If a feed is not properly formed, it will not always be valid for reading. W - Website Updates RSS feeds can be set up to notify visitors when a website changes.

X - XML
RSS is a subset of XML, or eXtensible Markup Language.

Y - Yahoo Answers
Yahoo's interactive system of questions and answers can be tracked using RSS feeds. You can create keyword or category feeds for anything in Yahoo Answers.

Z - Zero
Feeds Not having RSS feeds for your website puts you at a competitive disadvantage. RSS feeds bring traffic and help the stickiness of your website.
