Resource Description Framework (RDF) [W3C recommendation standard] is a mo

references section to find the link to the basic introduction to this simple format. The actual XML format is irrelevant. In fact, because the technology described applies to any type of XML content, there is no need to describe the software. You can use this technology to describe the catalog, employee information, or even the restaurant's liquor list. All the code and data files used in this example can be downloaded from the reference link.Document Definition In the 4SS XML resource library,

-standard iterator, I don't know how Jena's designers think about it. To be proficient, you must have a global understanding of the entire Jena API. In the loop, every element we get is a resource, because everything in the ontology is a resource, whether you want to get subject, property or object, in Jena, all resources are actually obtained. In Jena, property is the sub-interface of resource, and Jena does not have the subject or object interface. (Note: In the owl ontology, subject-> proper

standard allows us to assign metadata to any content that can be identified using URLs. The standard RDF/XML syntax for this operation appeared in 1999, and its complexity and difficulty have left many people away. By using existing HTML attributes and adding new attributes, XHTML 2 allows us to add metadata about documents and document components using the new and simpler RDFa syntax (you can use an about attribute to identify them ).

There is a clear definition of the relationship between concepts, such as software-generated files, software dependent on software, file versions, files with themes, location points. The goal is to automatically process information. It provides intelligent services such as information proxy, search proxy, and information filte

Breaking backwards compatibility is a contentious issue. Some commentators believe that keeping (X) the name of HTML only modifies the version number can create confusion. Ot

Create, read, update, and delete (Create/read/update/delete,crud) operations are the most basic database operations, but they are also the most important operations. CRUD operations are usually done using the Structured Query Language (structured query language,sql) in the relational database system. As the Web becomes more data-oriented, it needs to move from sql-based crud operations to a semantic Web based crud operation. Learn how to use PHP to perform CRUD operations through a semantically
