<content:encoded><![CDATA[<div class='snap_preview'><p><a href="http://feeds.feedburner.com/churchethos"><img class="alignright size-full wp-image-352" style="border:medium none;" title="rss8" src="http://churchethos.wordpress.com/files/2008/11/rss8.jpg" alt="rss8" width="214" height="161" /></a>Since I didn&#8217;t have any time today to post anything important, I thought I would invite my readers to subscribe to my blog. So here is a somewhat humorous look at why I think you should <a href="http://feeds.feedburner.com/churchethos" target="_blank">subscribe</a> to my blog today!</p>
<p><strong>Why Should I Subscribe to ChurchETHOS?</strong></p>
<p>I know not everyone uses a <a href="http://www.google.com/reader" target="_blank">Feed Reader</a> but I hope those who do will subscribe to my content. Why should you subscribe to ChurchETHOS?</p>
<p><a href="http://feeds.feedburner.com/churchethos style="><img class="alignnone size-full wp-image-333" style="border:none;" title="rss" src="http://churchethos.wordpress.com/files/2008/11/rss.jpg" alt="rss" width="20" height="20" /></a> A subscription to my blog will ensure that you always step in it while it&#8217;s still fresh (and hopefully some of it will stick to your shoe so that others can get a whiff).</p>
<p><a href="http://feeds.feedburner.com/churchethos"><img class="alignnone size-full wp-image-335" style="border:none;" title="rss2" src="http://churchethos.wordpress.com/files/2008/11/rss2.jpg" alt="rss2" width="20" height="20" /></a> It&#8217;s an easy process and it&#8217;s free. That&#8217;s right, my content isn&#8217;t worth paying for <img src='http://s.wordpress.com/wp-includes/images/smilies/icon_wink.gif' alt=';)' class='wp-smiley' />  Just click <a href="http://feed.feedburner.com/churchethos" target="_blank">here</a> (or don&#8217;t).</p>
<p><a href="http://feeds.feedburner.com/churchethos"><img class="alignnone size-full wp-image-334" style="border:none;" title="rss1" src="http://churchethos.wordpress.com/files/2008/11/rss1.jpg" alt="rss1" width="20" height="20" /></a> An <a href="http://www.feedburner.com/fb/a/emailverifySubmit?feedId=2606186&#38;loc=en_US" target="_blank">email subscription</a> will send my posts directly to your inbox. That way if you don&#8217;t like it or it makes you angry, you can have the satisfaction of sending it to the trash can. You can even print it out and physically crush it in your hand before throwing it in the trash can (but that&#8217;s not very environmentally friendly&#8230;or friendly).</p>
<p><a href="http://feeds.feedburner.com/churchethos"><img class="alignnone size-full wp-image-336" style="border:none;" title="rss3" src="http://churchethos.wordpress.com/files/2008/11/rss3.jpg" alt="rss3" width="20" height="20" /></a> You won&#8217;t check my blog one day and discover that nothing new has happened, <strong>OR</strong>, check my blog one day and realize you are way behind. All that wasted time stalking my blog could be spent stalking me on <a href="http://twitter.com/nathancreitz" target="_blank">Twitter</a>.</p>
<p><a href="http://feeds.feedburner.com/churchethos"><img class="alignnone size-full wp-image-337" style="border:none;" title="rss4" src="http://churchethos.wordpress.com/files/2008/11/rss4.jpg" alt="rss4" width="20" height="20" /></a> It&#8217;s like being subscribed to a newspaper. Except you don&#8217;t have to put on your wife&#8217;s bath robe and slippers just to walk out in the snow and retrieve your paper from <span style="text-decoration:line-through;">the neighbor&#8217;s</span> your sidewalk. How embarrassing! Oh yeah, and it&#8217;s nothing like being subscribed to a newspaper.</p>
<p><a href="http://feeds.feedburner.com/churchethos"><img class="alignnone size-full wp-image-338" style="border:none;" title="rss5" src="http://churchethos.wordpress.com/files/2008/11/rss5.jpg" alt="rss5" width="20" height="20" /></a> Subscribing to my feed will make me feel more important than I really am. Then, if I start sounding self-aggrandizing in my posts, you get to come in and set me straight in the comments section. You will be doing God&#8217;s work by holding me accountable. (By the way &#8211; self-aggrandizing, huh? &#8211; impressive word choice isn&#8217;t it? Look at me&#8230;look at me!)</p>
<p><a href="http://feeds.feedburner.com/churchethos"><img class="alignnone size-full wp-image-343" style="border:none;" title="rss7" src="http://churchethos.wordpress.com/files/2008/11/rss7.jpg" alt="rss7" width="20" height="20" /></a> I won&#8217;t have time to post anything today (other than this post), so make sure you get future content by <a href="http://feeds.feedburner.com/churchethos" target="_blank">subscribing now</a>.</p>
<p><a href="http://feeds.feedburner.com/churchethos"><img class="alignnone size-full wp-image-339" style="border:none;" title="rss6" src="http://churchethos.wordpress.com/files/2008/11/rss6.jpg" alt="rss6" width="20" height="20" /></a> ***BONUS*** If you need a reason for others to subscribe to <strong>YOUR</strong> blog and thought these were good reasons to sign up, please link to this post, <a href="mailto:nathan.creitz@gmail.com" target="_blank">email</a> me with the url, and in a few weeks I will write a thank you post that will include a link to your blog. Your readers will get great reasons to subscribe to <strong>YOUR</strong> blog, but will mistakenly end up subscribing to <strong>MY</strong> blog &#8211; but at least you will get some link love. (If you arrived here from another blog, you can subscribe to <strong>THEIR</strong> blog <a href="http://feeds.feedburner.com/churchethos" target="_blank">here</a>).</p>
<p>Finally, If you already have more subscribers than me (you do), you should still link to this post&#8230;I won&#8217;t bore you with reasons because I wouldn&#8217;t want to insult your intelligence with something like &#8220;The 15 Reasons Why More Successful Bloggers Than Myself Should Link to Such an Unimportant Blog as This One&#8221;. Because if I wanted to, I could. You probably already know all of those reasons so please just subscribe to me and send me a link and I&#8217;ll show you some link love too and we won&#8217;t worry about such trivial things like &#8220;reasons&#8221;.</p>

<content:encoded><![CDATA[<div class='snap_preview'><p>Na hora de gerar conteúdo XML para ser disponibilizado para outros aplicativos através de APIs, qual formato de feeds escolher? RSS, RDF, ATOM, ou algum outro?</p>
<p>Digamos que você é o provedor de conteúdo, e você mesmo irá desenvolver um 3rd part component para ler este conteúdo o qual poderá ser instalado em serviços como Netvibes, iGoogle, Live, Orkut, Desktop, entre outros, a flexibilidade é grande e a escolha muito importante.</p>
<p>Visto que se no futuro você resolver não mais disponibilizar a informação no formato X, mas sim no formato Y, deverá ter que re-codificar o componente e suas funcionalidades, ou seja, re-trabalho e mais investimentos ($ e tempo).</p>
<p>Podemos dizer a grosso modo que RDF refere-se a versão 1.0 do padrão RSS e possui a possibilidade de agregar mais informações (mais extensível) que o RSS 2.0 que é uma versão mais simples de trafegar informações a serem sindicalizadas.</p>
<p>Como o propósito deste Blog é apresentar as soluções que tomei quando me deparei com certos problemas e o porquê delas terem sido tomadas, lá vai: Há algumas semanas desenvolvi um módulo (gadget/widget) para o Netvibes e iGoogle, que iria consumir (ler) informações de um XML que o site &#8220;moviemobz&#8221; fosse gerar. Nesta hora tive que decidir qual formato adotar, optei pelo RSS 1.0 RDF, pois teria a flexibilidade de enviar mais conteúdo para o módulo de forma mais organizada e o tempo de desenvolvimento para executar os ajustes necessários nele seria menor.</p>
<p>Porém, não discarto a possibilidade de gerar feeds RSS 2.0 para outros leitores ou para ser sindicalizado de outra forma, esta opção foi tomada dado que além de gerar o feed, eu terai que criar o agregador também. Caso contrário, aconselho dar preferência ao RSS 2.0 pela sua simplicidade e maior adoção no mercado.</p>
<p>O Atom nem foi considerado pois possui a menor participação no mercado, sendo lido em menor escala se comparado com os padrões RSS e apesar de ser originado da iniciativa da IETF a fim de criar normas e padrões para sindicalização, ainda não é um &#8220;standard&#8221;.</p>

<content:encoded><![CDATA[<div class='snap_preview'><p>След като установихме, че Youtube доминира над VBox7 с около 10 към 1, ето и <a href="http://topbloglog.com/video/">една справка, която показва кой и къде в блогосферата пуска клипчета</a>.</p>
<p>Броят клипове на ден варира между 1 и 9 дневно. Мисля че все още блог пространството ни отбягва безогледното ползване на чуждо съдържание за собствено изразяване. Няма нито един клип да е цитиран повече от 2 пъти.</p>

<content:encoded><![CDATA[<div class='snap_preview'><p>Ich bin ein absoluter Fan von Filmchen, die einem erklären, wie was geht. Hier ein ausgezeichnetes Exemplar, wozu RSS Feeds gut sind (in plain englisch):</p>
<p><span style='text-align:center; display: block;'><object width='425' height='350'><param name='movie' value='http://www.youtube.com/v/0klgLsSxGsU&#038;rel=1&#038;fs=1&#038;showsearch=0&#038;hd=0' /><param name='allowfullscreen' value='true' /><param name='wmode' value='transparent' /><embed src='http://www.youtube.com/v/0klgLsSxGsU&#038;rel=1&#038;fs=1&#038;showsearch=0&#038;hd=0' type='application/x-shockwave-flash' allowfullscreen='true' width='425' height='350' wmode='transparent'></embed></object></span></p>
<p>Es gibt noch 2 weitere Möglichkeiten, die nicht erwähnt werden, aber noch einfacher sind, um RSS Feeds zu sammeln:</p>
<ul>
<li>iGoogle.com: siehe meinen Post: <a href="http://vanija.ch/2008/02/15/wie-abonniere-ich-eine-blog-in-5-schritten/">Wie abonniere ich einen Blog?</a></li>
<li>Apple Mail in Leopard (Mac OS X 10.5) links unter RSS und unter Ablage -&#62; RSS Feed hinzufügen.</li>

<p><strong>Geek RSS Stuff: What are the rules of podcast compliance?</strong><br />
THE TECH SPECS &#8211; <a href="http://en.wikipedia.org/wiki/IPod">According to Wikipedia</a>, &#8220;As of September 2007, the iPod had sold over 110 million units worldwide (stated in &#8220;The Beat Goes On&#8221; conference) making it the best-selling digital audio player series in history.&#8221; If you want an audience for your podcast you have to be able put your content on the iPod platform. There are plenty of tools that make it possible to do that, but to make it easier for folks to find you, and to make your podcast look more attractive in the iTunes interface, you may want to tweak that RSS feed.</p>
<p>If you are ready to take the leap into true XML hacking, <a href="http://www.apple.com/itunes/store/podcaststechspecs.html">Apple has the technical specification right here</a>. In short, this is the podcasters Bible. Thou shalt comply! (Resistance is futile&#8230;)</p>

<content:encoded><![CDATA[<div class='snap_preview'><p>RSS stands for &#8220;Really Simple Syndication&#8221;, while Atom is an XML language used for web feeds. Confused or want to know more? You can read the <a href="http://blog.mypacis.com/">Web 2.0 blog</a> for further information about RSS, Atom and Web 2.o in general; or Network with other Web 2.0 users on the <a href="http://www.mypacis.eu/">social network for development and Peace</a>; or simply read the overview we publish below. Wiki docet <img src='http://s.wordpress.com/wp-includes/images/smilies/icon_smile.gif' alt=':-)' class='wp-smiley' /> </p>
<p><em><strong>BLOG RSS: Rss </strong></em></p>
<p>RSS is a family of Web feed formats used to publish frequently updated content such as blog entries, news headlines or podcasts. An RSS document, which is called a &#8220;feed&#8221;, &#8220;web feed&#8221;, or &#8220;channel&#8221;, contains either a summary of content from an associated web site or the full text. RSS makes it possible for people to keep up with their favorite web sites in an automated manner that&#8217;s easier than checking them manually. RSS content can be read using software called a &#8220;feed reader&#8221; or an &#8220;aggregator.&#8221; The user subscribes to a feed by entering the feed&#8217;s link into the reader or by clicking an RSS icon in a browser that initiates the subscription process. The reader checks the user&#8217;s subscribed feeds regularly for new content, downloading any updates that it finds.</p>
<p>The initials &#8220;RSS&#8221; are used to refer to the following formats:</p>
<p>- Really Simple Syndication (RSS 2.0)<br />
- RDF Site Summary (RSS 1.0 and RSS 0.90)<br />
- Rich Site Summary (RSS 0.91)</p>
<p>RSS formats are specified using XML, a generic specification for the creation of data formats.</p>
<p><em><strong>ATOM USAGE</strong></em></p>
<p>Web feeds are used by the weblog community to share the latest entries&#8217; headlines or their full text, and even attached multimedia files. (See podcasting, vodcasting, broadcasting, screencasting, Vloging, and MP3 blogs.) These providers allow other websites to incorporate the weblog&#8217;s &#8220;syndicated&#8221; headline or headline-and-short-summary feeds under various usage agreements. Atom and other web syndication formats are now used for many purposes, including journalism, marketing, bug-reports, or any other activity involving periodic updates or publications. Atom also provides a standardized way to export an entire blog, or parts of it, for backup or for importing into other blogging systems. A program known as a feed reader or aggregator can check webpages on behalf of a user and display any updated articles that it finds. It is common to find web feeds on major Web sites, as well as many smaller ones. Some websites let people choose between RSS or Atom formatted web feeds; others offer only RSS or only Atom. In particular, many blog and wiki sites offer their web feeds in the Atom format.</p>
<p>Client-side readers and aggregators may be designed as standalone programs or as extensions to existing programs like web browsers. Browsers are moving toward integrated feed reader functions, such as Safari RSS, Web Browser for S60, Opera, Firefox and Internet Explorer. Such programs are available for various operating systems. Web-based feed readers and news aggregators require no software installation and make the user&#8217;s &#8220;feeds&#8221; available on any computer with Web access. Some aggregators syndicate (combine) web feeds into new feeds, e.g., taking all football related items from several sports feeds and providing a new football feed. There are also search engines for content published via web feeds, including Technorati and Blogdigger.</p>
<p><em><strong>Atom Compared to RSS 2.0 </strong></em></p>
<p>One difference between the two is that RSS 2.0 may contain either plain text or escaped HTML as a payload, with no way to indicate which of the two is provided, while Atom uses an explicitly labeled (i.e. typed) &#8220;entry&#8221; (payload) container. It allows for a wider variety of payload types including plain text, escaped HTML, XHTML, XML, Base64-encoded binary, and references to external content such as documents, video and audio streams, and so forth. Other differences include:<br />
- RSS 2.0 has a &#8220;description&#8221; element which can contain either a full entry or just a description. Atom has separate “summary” and “content” elements. Atom thus allows the inclusion of non-textual content that can be described by the summary.<br />
- Atom is defined within an XML namespace whereas RSS 2.0 is not.<br />
- Atom specifies use of the XML&#8217;s built-in xml:base for relative URIs. RSS 2.0 does not have a means of differentiating between relative and non-relative URIs.<br />
- Atom uses XML&#8217;s built-in xml:lang attribute as opposed to RSS 2.0&#8217;s use of its own &#8220;language&#8221; element.<br />
- In Atom, it is mandatory that each entry have a globally unique ID, which is important for reliable updating of entries.<br />
- Atom 1.0 allows standalone Atom Entry documents whereas with RSS 2.0 only full feed documents are supported.<br />
- Atom specifies that dates be in the format described in RFC 3339 (which is a subset of ISO 8601). The date format in RSS 2.0 was underspecified and has led to many different formats being used.<br />
- Atom 1.0 has IANA-registered MIME-type. RSS 2.0 feeds are often sent as application/rss+xml, although it is not a registered MIME-type.<br />
- Atom 1.0 includes an XML schema. RSS 2.0 does not.<br />
- Atom is an open and evolvable standard developed through the IETF standardization process. RSS 2.0 is not standardized by any standards body. Furthermore according to its copyright it may not be modified.<br />
- Atom 1.0 elements can be used as extensions to other XML vocabularies, including RSS 2.0 as illustrated in a weblog post by Tim Bray entitled &#8220;Atomic RSS&#8221;.<br />
- Atom 1.0 describes how feeds and entries may be digitally signed using the XML Digital Signature specification such that entries can be copied across multiple Feed Documents without breaking the signature.<br />
- Despite the emergence of Atom as an IETF Proposed Standard and the decision by major companies such as Google to embrace Atom, use of the older and more widely known RSS 1.0 and RSS 2.0 formats has continued.<br />
- RSS 2.0 support for enclosures led directly to the development of podcasting. While many podcasting applications, such as iTunes, support the use of Atom 1.0, RSS 2.0 remains the preferred format [5].<br />
- Many sites choose to publish their feeds in only a single format. For example CNN, the New York Times, and the BBC offer their web feeds only in RSS 2.0 format.<br />
- News articles about web syndication feeds have increasingly used the term &#8220;RSS&#8221; to refer generically to any of the several variants of the RSS format such as RSS 2.0 and RSS 1.0 as well as the Atom format. (For example, &#8220;Fine-Tuning Your Filter for Online Information&#8221; (NYT) and &#8220;There&#8217;s a Popular New Code for Deals: RSS&#8221; (NYT January 29, 2006))<br />
- Each of the various web syndication feed formats has attracted large groups of supporters who remain satisfied by the specification and capabilities of their respective formats.<br />
- Atom supports multiple link elements per entry, a feature which can be used to specify enclosures of different types. This eliminates the need for separate feeds for podcasts that provide multiple file formats.</p>
