The rich web layer in the graph shows the areas of interest and the technology of development. The web architecture is depicted as a series of layers, each of which is built on top of another layer.

In the case of RDF data query or description, SPARQL whether from birth, standard or operating habits are a good choice, but for a beginner more or less "taboo" means, operation is a bit timid, so just use this time to summarize and learn language, The language features are one by one cracked. Simple query 1, general formula (basic key) select? o where{s p? o} Break: Class SQL is the choice of mapping, and SPARQL itself based on the ternary group in

select XML. For example, some companies and individuals may have multiple addresses, phone numbers, and email accounts. Multiple such information fragments can be easily declared in the XML structure. The vCard structure is often used to indicate contact information on the Internet. it is independent of the platform and can easily generate and import different applications. It supports some flexibility in the XML structure, but is actually a simple text-based format that uses declarative fields

RSS, RDF, AtomRSS (Really Simple Syndication, truly Simple Joint Supply System), RDF (Resource Description Framework, Resource Description Framework) and atom are standard subscription modes. Although the differences between the three are important for software development engineers, there is almost no big difference for those who use the subscriber. Atom is the latest

People who have used Firefox are sure to install Firefox extensions so they can play the full power of Firefox. The general extension is a file with the suffix.

, the ontology actually plays the role of the database, so when there are many data (individuals), efficiency will be very problematic. (Protege's owl editing tool provides the ability to generate an EMF model from the ontology.CodeAlthough the current version is Alpha, this may be a good choice for synchronizing the two models .) The method above is modified so that the ontology does not store individuals. Modifications to the Java instance set are eventually reflected in the relational data

Rule Description: A rule is a way to represent knowledge. It generally exceeds the expression capability of owl1. A Semantic web rule is a typical Condition Statement: if-then. New knowledge is added only when a specific statement is true. The Jena framework comes with a reasoning engine and a recognized rule language. Its advantages are that the jena framework is relatively simple to use and its disadvantages are not w3c reasoning standards. Ontology modeling: 1 import com. clarkparsia. spar
