RSS系列三:RSS订阅软件GreatNews

06月 25th, 2008 ychen

试了挺多RSS订阅的软件,包括FeedDemon,SharpReaderRss,国内的周博通,新浪的等,国外的有些不支持中文,或者支持不好,有些中文显示还有乱码。

现在我用的是GreatNews,支持多国语言,支持unicode,而且速度比较快,还有绿色版。其他也没什么好介绍了。对,还有支持proxy,import/export rss列表(以opml或者xml格式)这些个基本大家都支持的功能。

RSS系列二:RSS的应用

06月 24th, 2008 ychen

如果RSS已经应用到几乎互联网的各个角落,一般大的网站都提供RSS的输出,网上也有很多RSS订阅软件,及在线的RSS订阅服务。在线的RSS订阅比较有名的是zhuaxia.com跟google的google reader等。

RSS的输出跟应用很简单,输出的站点在更新的时候就会同时更新它的输出rss的xml文件,比如我的这个WP搭建的blog平台也一样,一般的blog开源平台或者sina,sohu等大型blog站也都会提供rss输出。当你更新内容的时候,输出的xml也跟着更新了。而订阅的软件或者网站呢,一般都是会定时的去读一下那个xml文件。如果有更新,就把这部分新内容down下来。

RSS的用途大致如此,下回介绍RSS的具体用法,比如订阅器,在线RSS订阅。

RSS系列一:什么是RSS?

06月 24th, 2008 ychen

什么是RSS呢?

RSS(Really Simple Syndication)是一种描述和同步网站内容的格式,是目前使用最广泛的XML应用。RSS搭建了信息迅速传播的一个技术平台,使得每个人都成为潜在的信息提供者。发布一个RSS文件后,这个RSS Feed中包含的信息就能直接被其他站点调用,而且由于这些数据都是标准的XML格式,所以也能在其他的终端和服务中使用。

以下摘自wikipedia:

RSS is a family of Web feed formats used to publish frequently updated content such as blog entries, news headlines, and podcasts in a standardized format.[2] An RSS document (which is called a "feed", "web feed"[3], or "channel") 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 web sites in an automated manner that can be piped into special programs or filtered displays.[3]

The benefit of RSS is the aggregation of content from multiple Web sources in one place. RSS content can be read using software called an "RSS reader", "feed reader" or an "aggregator", which can be web-based or desktop-based. A standardized XML file format allows the information to be published once and viewed by many different programs. The user subscribes to a feed by entering the feed’s link into the reader or by clicking an RSS icon in a browser that initiates the subscription process. The RSS reader checks the user’s subscribed feeds regularly for new content, downloading any updates that it finds and provides a user interface to monitor and read the feeds.

The initials "RSS" are used to refer to the following formats:

  • Really Simple Syndication (RSS 2.0)
  • RDF Site Summary (RSS 1.0 and RSS 0.90)
  • Rich Site Summary (RSS 0.91).

RSS formats are specified using XML, a generic specification for the creation of data formats. Although RSS formats have evolved since March 1999,[4] the RSS icon ("") first gained widespread use in 2005/2006.

The Firefox and Internet Explorer 7 Feed icon.这个是rss的图标,不过还有许多不同的版本。但都大同小异。说了这么多,其实RSS就是一个规定格式的xml。
