rdf graph

distinguish between different types of nodes (elements, attributes, character data, annotations, etc.), and make it possible to perform different actions depending on the node type and node depth of the document tree. Sax and Dom parsers support almost every language, including your favorite--php. I'll use PHP's SAX parser to deal with RDF examples in this article. Of course, it's also easy to use a DOM parser. Let's take a look at this simple exam

web| Insert | The site returns to the class (Back to Class) Since you have so much power, why should you limit yourself to just a single source of RDF? As I said earlier, most major sites often take snapshots of what they provide. In fact, it's fairly easy to insert all these different sources into your site. Let's see how it's done. First, we modularize the code in the previous example. In this way, you don't have to rewrite the same code over and

web| Insert | Site nesting time (Nesting times) The previous example is just for illustration of the problem. If you really want to insert RDF content into a Web site, you need to do something a little better. So the previous script has been improved to add something to simplify the task of formatting RDF data. XML file $file = "HTTP://WWW.FRESHMEAT.NET/BACKEND/FM-RELEASES.RDF"; Set up some variable

1 Reputation and great wealthImagine a site that gets the latest news from the hottest portal site. Stock prices, weather information, news stories, thread discussion groups, software releases ... All of this will be dynamically updated once per hour without any manual intervention. We can imagine this attendant site traffic, a steady stream of advertising revenue and the "flattery" of the adult administrator.But now, stop fantasizing and start reading, because as long as you keep an eye on the

How to register a single (RDF) file into the system. 1. First upload this file to the corresponding $pord_top/reports/us, if it is in Chinese, it should be put to $pord_top/reports/zhs, other languages similar 2.System administrator responsibilities, Concurrent > program->executable (can also be defined under Application developer responsibilities, menu is slightly different) Executable name: random, usually equal to the report nameShort name: Random

number of Also note the change in the $flag variable, which now holds two values, depending on whether the Once the document is parsed, things are simple--traverse the $items array and print each entry (item) in a tabular format. The results of the journey are as follows: 　 7) Return to Class (Back to Class)Since you have so much power, why should you limit yourself to just a single source of RDF? As I said earlier, most major sites often take snapsh

Recently began to seriously learn the algorithm, with the Sedgewick of the "algorithms". Much of the content is the same as the data structure, the difference is the content of the algorithm more explanation. I often keep track of the difficulties I encounter in learning algorithms and how to solve them.The problem of judging the existence loop is encountered when learning the topological sort. The problem of judging the ring is divided into the direction gr
