Content Type Xml

Posted on  by admin

XML has two MIME types, application/xml and text/xml. These are often used interchangeably, but there is a subtle difference which is why application/xml is generally recommended over the latter. Let me explain why: according to the standard, text/*-MIME types have a us-ascii character set unless otherwise specified in the HTTP headers.

RSS Feeds have a content type problem. Most people end up serving them with the content-type: text/xml. But this practice is frowned upon for several reasons. The main reason people don't like text/xml is because its very vague, there are content types such as application/rss+xml, application/rdf+xml, and application/atom+xml that describe the content of your feed much better than text/xml does. We should be using these types for our feeds. The problem, however with the more descriptive content types is that Firefox and IE prompt you to download the XML file instead of displaying it in the browser like it would a text/xml document.

So for IE, Firefox, and Safari 1.x my feed will be served in text/xml other clients will get the proper application/rss+xml MIME type. Here's my code for this: I realize that this is not a perfect solution, it may cause browser plugins to have to do some extra work to determine if the document is an RSS, RDF or Atom Feed.

Additionally if aggregators are including Mozilla in their user agent, they will get text/xml. But I'm not going to risk loosing potential subscribers over this issue, as some bloggers have reported to be the case when switching. So I will serve a variable content-type at least until is fixed in a production release of FireFox (or if IE beats them I guess:). Autodesk autocad 2008 download free. You can vote for that bug in bugzilla if you find the save dialog to be annoying when you click on RSS feeds. I also hope that IE7 is will serve the rss related content-types as it would a text/xml doc by default. Scoble, can you make sure IE7 deals with this?

Fortunately, RSS contains some publication and expiry-date data to help intermediate software do this, but to do this it has to recognize the data as RSS and read this stuff. This isn't going to happen until RSS gets served with the proper Media-type. • When someone writes RSS-reader code to live in the Web Browser, it's going to need a consistent Media-type to be able to recognize RSS. Cites some of the problems with text/xml such as the character set issues: The default character set, which must be assumed in the absence of a charset parameter, is US-ASCII or ISO-8859-1 for all MIME types prefixed by text, depending of the Request for Comment you are considering. Of course, having two different specifications is confusing to the software industry. But also, no one of these two charsets can support complex foreign charsets as those used in Asia.

Adam, Where I see the benefits of a new media type is for http middleware such as caching, or proxies. If they can quickly determine the type of document from its headers with out actually inspecting or parsing it, this is good for performance. So having mime types for RSS, RDF, and ATOM would improve performance of the applications that use them. I agree however that we shouldn't be declaring new MIME types for every possible variant of XML.

But RSS, RDF, and ATOM are quite popular, and I think that justifies creating having a new mime type. SkipDays and SkipHours can easily be represented by sending the appropriate 'Expires' header on your RSS. If you don't update on the weekend, just set your Expires header to Monday Morning. Additionally, the SkipDays and SkipHours information is embedded in the RSS file itself, which means your cacheing server must be parsing the XML data. If it is, then it can recognize the DTD or Schema information just as easily as it can recognize the SkipDays/SkipHours information.
