Abstract: It may be a while before Internet telephony with VoIP (Voice over Internet Protocol) reaches critical mass, but there's already tremendous movement in that direction. A lot of organizations are not only attracted to VoIP's promise of cost savings, but its ability to move data, images, and voice traffic over the same connection. Think of it: a single Internet phone call can take information sharing to a whole new level. That's why many IT administrators and developers are actively looking to set up VoIP-based private telephone switching systems within the enterprise. The efficiency that network users can reach with it is almost mind-boggling. And cheap, if the system is built with open source software like Asterisk. There are commercial VoIP options out there, but many are expensive systems running old, complicated code on obsolete hardware. Asterisk runs on Linux and can interoperate with almost all standards-based telephony equipment. And you can program it to your liking. Asterisk's flexibility comes at a price, however: it's not a simple system to learn, and the documentation is lacking. Asterisk: The Future of Telephony solves that problem by offering a complete roadmap for installing, configuring, and integrating Asterisk with existing phone systems. Our guide walks you through a basic dial plan step by step, and gives you enough working knowledge to set up a simple but complete system. What you end up with is largely up to you. Asterisk embraces the concept of standards-compliance, but also gives you freedom to choose how to implement your system. Asterisk: The Future of Telephony outlines all the options, and shows you how to set up voicemail services, call conferencing, interactive voice response, call waiting, caller ID, and more. You'll also learn how Asterisk merges voice and data traffic seamlessly across disparate networks. And you won't need additional hardware. For interconnection with digital and analog telephone equipment, Asterisk supports a number of hardware devices. Ready for the future of telephony? We'll help you hook it up.

Abstract: If you're a developer working with XML, you know there's a lot to know about XML, and the XML space is evolving almost moment by moment. But you don't need to commit every XML syntax, API, or XSLT transformation to memory; you only need to know where to find it. And if it's a detail that has to do with XML or its companion standards, you'll find it--clear, concise, useful, and well-organized--in the updated third edition of XML in a Nutshell .With XML in a Nutshell beside your keyboard, you'll be able to: Quick-reference syntax rules and usage examples for the core XML technologies, including XML, DTDs, Xpath, XSLT, SAX, and DOM Develop an understanding of well-formed XML, DTDs, namespaces, Unicode, and W3C XML Schema Gain a working knowledge of key technologies used for narrative XML documents such as web pages, books, and articles technologies like XSLT, Xpath, Xlink, Xpointer, CSS, and XSL-FO Build data-intensive XML applications Understand the tools and APIs necessary to build data-intensive XML applications and process XML documents, including the event-based Simple API for XML (SAX2) and the tree-oriented Document Object Model (DOM) This powerful new edition is the comprehensive XML reference. Serious users of XML will find coverage on just about everything they need, from fundamental syntax rules, to details of DTD and XML Schema creation, to XSLT transformations, to APIs used for processing XML documents. XML in a Nutshell also covers XML 1.1, as well as updates to SAX2 and DOM Level 3 coverage. If you need explanation of how a technology works, or just need to quickly find the precise syntax for a particular piece, XML in a Nutshell puts the information at your fingertips.Simply put, XML in a Nutshell is the critical, must-have reference for any XML developer.

Details

Language: English

Pages: xi, 208 p. ; , 24 cm

Parallel Title: Erscheint auch als

DDC: 005.7/2

Keywords: Metadata ; Web site development ; XML (Document markup language) ; Electronic books ; local

Abstract: RSS is sprouting all over the Web, connecting weblogs and providing news feeds. Originally developed by Netscape in 1999, RSS (which can stand for RDF Site Summary, Rich Site Summary, or Really Simple Syndication) is an XML-based format that allows web developers to describe and syndicate web site content. Using RSS files allows developers to create a data feed that supplies headlines, links, and article summaries from a web site. Other sites can then incorporate them into their pages automatically. Although RSS is in widespread use, people struggle with its confusing and sometimes conflicting documentation and versions. Content Syndication with RSS is the first book to provide a comprehensive reference to the specifications and the tools that make syndication possible. Content Syndication with RSS offers webloggers, developers, and the programmers who support them a thorough explanation of syndication in general and RSS in particular. Written for web developers who want to offer XML-based feeds of their content, as well as developers who want to use the content that other people are syndicating, the book explores and explains metadata interpretation, different forms of content syndication, and the increasing use of web services in this field. This concise volume begins with an introduction to content syndication on the Internet: its purpose, limitations, and traditions, and answers the question of why would you consider "giving your content away" like this? Next, the book delves into the architecture of content syndication with an overview of the entire system, from content author to end user on another site. You'll follow the flow of data: content, referral data, publish-and-subscribe calls, with a detailed look at the protocols and standards possible at each step. Topics covered in the book include: Creating XML syndication feeds with RSS 0.9x and 2.0 Beyond headlines: creating richer feeds with RSS 1.0 and RDF metadata Using feeds to enrich a site or find information Publish and subscribe: intelligent updating News aggregators, such as Meerkat, Syndic8, and Newsisfree, and their web services Alternative industry-centric standards If you're interested in producing your own RSS feed, this step-by-step guide to implementation is the book you'll want in hand.
