Data feed is a mechanism for users to receive updated data from data sources. It is commonly used by real-time applications in point-to-point settings as well as on the World Wide Web. The latter is also called web feed. News feed is a popular form of web feed. RSS feed makes dissemination of blogs easy. Product feeds play increasingly important role in e-commerce and internet marketing. Data feeds usually requires structured data.
The Web is evolving into a web of data or Semantic Web. Data will be encoded by Semantic Web languages like RDF or OWL according to many experts' visions. So, it is not difficult to envision data feeds will be also in the form of RDF or OWL. A big advantage of providing semantic data feeds, i.e. feeding data in Semantic Web standards, is that the data can then be readily consumed and reused by other computers.
CSV datafeeds are mostly being used within the affiliate marketing. Affiliate or so called publisher websites load the CSV file to load product information from online webshops. This way it is a lot easier to load thousands of product to the website. CSV is not like XML and is not as semantic but it does have a good basic structure. This file format can easily be created and loaded with any spreadsheet program like Excel.
HVAC Equations, Data, and Rules of Thumb, 3e offers all of the information an HVAC student or professional needs in one resource. The book thoroughly explains the expansion of piping systems and temperature limitations of new materials such as polyethylene, polypropylene, PVC, CPVC, and PEX. Detailed information is included for all types of facilities, including offices, hotels, hospitals, restaurants, commercial spaces, and computer rooms.
This practical handbook reflects all the latest code changesâincluding the ASHRAE standardsâand explains how to interpret and put them to use. It includes completely updated coverage of new pumps, chillers, air handling units, cooling equipment, boilers, and pipe material. You will get complete coverage of sustainability organizations that have become more important since last edition, including LEED, USGBC, Energy Star.

Machining is one of the most important manufacturing processes, which remove unwanted material in the form of chips from a workpiece. Material removal operations are among the most expensive; in the U.S. alone, more than $100 billion were spent on machining in 1999. These high costs put tremendous economic pressures on production managers and engineers as they struggle to find ways to increase productivity.
Machining recommendations provided in this book cover turning since it allows removing more material per unit of time and consuming more power at the roughing operations than end milling, boring or drilling. Machining recommendations relate to cutting speeds, feed rates, and depth of cuts. Such recommendations depend on the workpiece material properties and the cutting tool material. Workpiece materials described in this book are the most commonly used grades of carbon, alloy, stainless, tool, and maraging steels. Cutting tool materials are cemented carbides, cermets, and ceramics.
A pocket-size reference that has all the fundamental data that engineers need in their daily work. Taping and drilling charts, hole coordinate charts with common sizes already worked out, speeds/feeds, material specs, drawing symbols and standards, CNC machine codes, plus much more. Ideal for mechanical, manufacturing, and design engineers, draftsmen, toolmakers, machinists, students, and hobbyists
This is the right choice for you if you want a pocket reference that â¦
* Is compact, lightweight, easy-to-carry and really does fit in your pocket.
* Contains the essential data you need practically every day, yet is uncluttered by extraneous information.
* Is organized so you can easily locate the data you need very quickly.
* Contains data not found in similar books, such as thread charts showing all effective sizes.

Featuring fiction, food, and fun, this unique approach motivates young people to read and builds their comprehension skills while extending their learning across the curriculum. Students, teachers, librarians, parents, and community members can participate in these mealtime programs, which include such activities as games, writing or art projects, role-playing, storytelling, interviewing, and guest speakers. Based on the authors' READ 'N' FEED program, the book provides detailed plans for learning events developed from selected young adult novels. For each title, the authors provide a summary of the plot; a booktalk; background information on the author; discussion questions; activities; novel connections; suggestions for food and decorations; and reproducible templates of publicity posters, student invitations, game pieces, and other materials. The authors also give instructions on how to design a program for other books. This method integrates critical-thinking skills, multiple intelligences metho
Perhaps the most explosive technological trend over the past two years has been blogging. As a matter of fact, it's been reported that the number of blogs during that time has grown from 100,000 to 4.8 million-with no end to this growth in sight.What's the technology that makes blogging tick? The answer is RSS--a format that allows bloggers to offer XML-based feeds of their content. It's also the same technology that's incorporated into the websites of media outlets so they can offer material (headlines, links, articles, etc.) syndicated by other sites.As the main technology behind this rapidly growing field of content syndication, RSS is constantly evolving to keep pace with worldwide demand. That's where Developing Feeds with RSS and Atom steps in. It provides bloggers, web developers, and programmers with a thorough explanation of syndication in general and the most popular technologies used to develop feeds.This book not only highlights all the new features of RSS 2.0-the most recent RSS specification-but also offers complete coverage of its close second in the XML-feed arena, Atom. The book has been exhaustively revised to explain:
