How Blog software such as Windows Live Writer access Blogs

Question

I am wondering How a blog software such as Windows Live writer reads/updates so many blogs such as Telligent, Wordpress, Blogger blogs.

Is there a commom web services standard exposed by these blog providers?

I have a telligent blog hosted on blogs.msdn.com and looking to access it contents in my custom web program. Any idea how can I do that ?

Answer 1

Windows Live Writer uses the MetaWeblog API to access blog and post information. Telligent's endpoint can be found at /blogs/metablog.ashx. Many other blog platforms use the same standard (although some such as Wordpress add additional features). The XML-RPC can be helpful when calling Meta Weblog services.
