Descrição do produto

Perhaps the most explosive technological trend over the past two years has been blogging. As a matter of fact, it's been reported that the number of blogs during that time has grown from 100,000 to 4.8 million-with no end to this growth in sight.What's the technology that makes blogging tick? The answer is RSS--a format that allows bloggers to offer XML-based feeds of their content. It's also the same technology that's incorporated into the websites of media outlets so they can offer material (headlines, links, articles, etc.) syndicated by other sites.As the main technology behind this rapidly growing field of content syndication, RSS is constantly evolving to keep pace with worldwide demand. That's where Developing Feeds with RSS and Atom steps in. It provides bloggers, web developers, and programmers with a thorough explanation of syndication in general and the most popular technologies used to develop feeds.This book not only highlights all the new features of RSS 2.0-the most recent RSS specification-but also offers complete coverage of its close second in the XML-feed arena, Atom. The book has been exhaustively revised to explain:

  • metadata interpretation
  • the different forms of content syndication
  • the increasing use of web services
  • how to use popular RSS news aggregators on the market
After an introduction that examines Internet content syndication in general (its purpose, limitations, and traditions), this step-by-step guide tackles various RSS and Atom vocabularies, as well as techniques for applying syndication to problems beyond news feeds. Most importantly, it gives you a firm handle on how to create your own feeds, and consume or combine other feeds.If you're interested in producing your own content feed, Developing Feeds with RSS and Atom is the one book you'll want in hand.

5.0 de 5 estrelas Get your creative juices flowing 10 de março de 2006
Por Jonathan M. Julian - Publicada na Amazon.com
Formato: Capa comum Compra verificada
Great intro to the history of RDF/RSS/Atom. Chapter 10 "Unconventional Feeds" will give you great ideas to create and manipulate feeds for yourself. Note that some content has been republished from "Content Syndication with RSS" (0596003838).

4.0 de 5 estrelas Good General Development Guide 10 de maio de 2005
Por Jase T. Wolfe - Publicada na Amazon.com
Formato: Capa comum
Both individuals who know what RSS/Atom feeds are but need information on how to develop and implement them, as well as intermediate users already publishing a feed and looking for more progressive information, will find value in this title. Advanced users will most likely not find anything they don't already know. Covering RSS 1.0, RSS 2.0 and Atom .05, readers are walked thru the basics and intermediate concepts of implementation starting with a general background history, end-user reader requirements and options, and syntax usage for each version. The book then concludes with more intensive topics, such as usage of industry standard RSS modules, development of custom RSS modules, syndication thru services or direct publication, as well as third-party utility scripts and resources.

A few items set this title apart. First, the author has not dedicated this only to those who wish to perform serious syndication. Time is spent both showing how anyone regardless of skill level can publish a feed without programming, and teaching them how to use various styles of feed readers and the etiquette behind subscribing. For those who wish to go beyond basic feed development, the author dedicates entire chapters to things such as RSS modules (by RSS version), programmatically developed feeds, creating feeds which self-publish data from other web sites or databases, and publishing your feed for various platforms. Readers should be aware that the majority of scripts presented within the title are in Perl or PHP, and either a working knowledge of those languages or of any scriptable language will be needed if you intend to go beyond the beginning / intermediate level; not having this knowledge does not detract from the overall value of the book.

This title shows that RSS/Atom feeds are not just for the minority any more. Complete chapters are dedicated to all three formats, presenting all material in and easy to read and understand format without wasting your time with fluff or thinly disguised plugs for 3rd party products. This is a good general guide that will maintain value after your initial read.

4.0 de 5 estrelas Good coverage, best if you're a Perl/PHP programmer... 8 de maio de 2005
Por Thomas Duff - Publicada na Amazon.com
Formato: Capa comum
I got an opportunity to review another RSS/Atom title called Developing Feeds with RSS and Atom by Ben Hammersley (O'Reilly). This is a pretty focused title targeted for developers.

Chapter List: Introduction; Using Feeds; Feeds Without Programming; RSS 2.0; RSS 1.0; RSS 1.0 Modules; The Atom Syndication Format; Parsing and Using Feeds; Feeds in the Wild; Unconventional Feeds; Developing New Modules; The XML You Need for RSS; Useful Sites and Software; Index

The author spends just a little time talking about the whys of RSS/Atom feeds and then dives into the guts of each of the specifications. For the developer looking to learn how to develop a syndicated feed, this focus will probably be highly appreciated. Another interesting part of the book is explanations of the politics behind the three main standards (RSS 1.0, RSS 2.0, and Atom). Unlike most naming standards, RSS 2.0 isn't an update of RSS 1.0, and Atom is a third beast that must be accounted for. When you read the history of how each one came into being, it makes a bit more sense as to how we got into this position. Doesn't make it any easier to accommodate things, but at least you can understand it.

From a programming perspective, most of the code is done in Perl with a smattering of Ruby and PHP mixed in. I personally would have liked to see a bit more attention paid to Java, but I guess you can't have everything. You can at least use the programs to get ideas on potential solutions even if you don't use/know Perl.

Overall, a good treatment of an important technology in today's internet environment, and a book that will be useful as you start to add syndication into your applications.

1.0 de 5 estrelas Sorely Lacking Content 26 de outubro de 2005
Por ths - Publicada na Amazon.com
Formato: Capa comum
This book has some good resource citings, and general information on RSS. It includes a lot of discussion on the previous iterations in the RSS geneology...up to the current RSS 2.0 specification.

The index is not very thorough.

I bought the book hoping to learn more about RSS feed development (as the title suggests). I was greatly disappointed. There is one chapter dedicated to RSS 2.0. Within the chapter there is a section entitled "Creating RSS 2.0 Feeds." This section--you would think is the core of the book-- is 8 pages long (if that) including 3 pages of Perl code examples.

Good luck if you want to learn about creating Atom feeds from this publication. There is a 14 page chapter dedicated to Atom. It is prefaced with a disclaimer indicating that code in the chapter may fail due to version rot (and to surf the web for answers). Also in this chapter, there is a section entitled "Producing Atom Feeds." This consists of 2 brief paragraphs explaining how the current Atom version is not worth addressing and suggests purchasing the next edition of the book to find out how to produce feeds using up to date libraries!!!

You can draw your own conclusions from all that.

This book falls far short of the quality O'Reilly books of yore.

4.0 de 5 estrelas decent book, but miserable subject to code 25 de abril de 2005
Por W Boudville - Publicada na Amazon.com
Formato: Capa comum
Blogs have become huge lately. And in related ways, so too has the idea of a parseable news feed. To try and enable all this, the book explains RSS and Atom. It's directed towards programmers working on a web site.

It is an awkward book to read, as it describes the RSS versions 1 and 2. Unlike other standards or software packages, where a version 2 supersedes version 1, here the RSS versions compete with each other! Yes, they are similar. But not quite. It is this dissimilarity that will give you heartburn. Hammersley explains that in general, when you connect up to an RSS feed, you can't tell which version it supports. So you have to grunge your code to support both. Grr!!

Worse, as he continues to explain, sometimes a newsfeed is not fully compliant with either version. Due to a combination of poor programming by that supplier and ambiguities in the interpretations of the RSS versions. Plus it gets "better". Some feeds are not even valid XML. Yuk! So you have to decide who liberal your parser should be. Analogous to the poorly formed HTML pages out there on the web, and the subsequent decisions by browsers as to how tolerant they should be of these.

Hammersley has done a decent job explaining RSS. It's just a miserable subject to code.
