"Wiring & electronics"--Cover, volume 4.

Digital Command Control (DCC) has greatly increased in popularity in recent years. Yet, most modelers need help navigating this tricky technology. DCC Projects & Applications, Volume 3 provides step-by-step instructions and how-to tips to show modelers how to set up, maintain, and operate DCC systems. This includes everything from layout wiring to decoder installation to light and sound effects. It also features information on the latest software, technology and upgraded manufacturer items.

Digital Command Control is a great way to run your model railroad, but setting it up and keeping it current can be overwhelming. DCC Projects & Applications, Volume 4 by DCC expert Larry Puckett simplifies the process with the most up-to-date and comprehensive information available. Compiled from Model Railroader's DCC Corner columns and feature articles, the latest volume includes dozens of updated step-by-step projects that show you how to: Fit sound decoders into tight areas. Install decoders in steam locomotives. Program decoders using DecoderPro‚. Divide layouts into power districts. Wire turnouts for DCC. Troubleshoot electrical problems. And much more!

Metadata is a key aspect of our evolving infrastructure for information management, social computing, and scientific collaboration. DC-2008 will focus on metadata challenges, solutions, and innovation in initiatives and activities underlying semantic and social applications. Metadata is part of the fabric of social computing, which includes the use of wikis, blogs, and tagging for collaboration and participation. Metadata also underlies the development of semantic applications, and the Semantic Web -- the representation and integration of multimedia knowledge structures on the basis of semantic models. These two trends flow together in applications such as Wikipedia, where authors collectively create structured information that can be extracted and used to enhance access to and use of information sources. Recent discussion has focused on how existing bibliographic standards can be expressed as Semantic Web vocabularies to facilitate the ingration of library and cultural heritage data with other types of data. Harnessing the efforts of content providers and end-users to link, tag, edit, and describe their information in interoperable ways (" participatory metadata") is a key step towards providing knowledge environments that are scalable, self-correcting, and evolvable. DC-2008 will explore conceptual and practical issues in the development and deployment of semantic and social applications to meet the needs of specific communities of practice.

"This updated edition includes cutting-edge information on new control systems and upgrades as well as recent technological advances, especially in sound decoder products and features. From the basics of how DCC works, choosing a DCC system, and installing a DCC decoder in locomotives to more advanced features such as decoder programming and how to control trains with computers, tablets, and other devices, The DCC Guide, 2nd Edition is the modeler s all-inclusive guide to controlling trains."--
