Some technologies about Publishing,XML,Feed’s and Blog’s

APML:

APML allows users to share their own personal Attention Profile in much the same way that OPML allows the exchange of reading lists between News Readers.

OPML:

OPML (Outline Processor Markup Language) is an XML format for outlines (often blogrolls). Originally developed by Radio UserLand as a native file format for an outliner application, it has since been adopted for other uses, the most common being to exchange lists of web feedsbetween web feed aggregators.

SIOC:

Semantically-Interlinked Online Communities Project (SIOC – pronounced “shock”) is a Semantic Web technology. SIOC provides methods for interconnecting discussion methods such as blogs, forums and mailing lists to each other. It consists of the SIOC ontology, an open-standard machine readable format for expressing the information contained both explicitly and implicitly in Internet discussion methods, of SIOC metadataproducers for a number of popular blogging platforms and content management systems, and of storage and browsing/searching systems for leveraging this SIOC data.

 RSD:
Really Simple Discovery (RSD) is an XML format and a publishing convention for making services exposed by blog, or other web software, discoverable by client software. It is a way to reduce the information required to set up editing/blogging software to three well known elements:
Username,Password, andHomepage URL.
Any other critical settings should either be defined in the RSD file related to the blog, or discoverable using the information provided.

ASF:

 Argotic Syndication Framework A powerful and extensible .NET web content syndication framework for RSS, Atom, OPML, APML, BlogML, RSD and more. The Argotic Syndication Framework is a Microsoft .NET class library framework that enables developers to easily consume and/or generate syndicated content from within their own applications. The framework makes the reading and writing syndicated content in common formats such as RSS, Atom, OPML, APML, BlogML, and RSD very easy while still remaining extensible enough to support common/custom extensions to the syndication publishing formats. The framework includes out-of-the-box implementations of the most commonly used syndication extensions, network clients for sending and receiving peer-to-peer notification protocol messages; as well as HTTP handlers, modules, services and controls that provide rich syndication functionality to ASP.NET developers.
