Ontology Web Language(OWL)

OWL is derived from DAML+OIL which is a language for expressing classifications and properties of resources. OWL adds more vocabulary for describing properties and classes. OWL is used to represent the meaning of terms in vocabularies and the relationships between those terms. OWL is divided onto three sub-language which is:


  • OWL Lite
  • OWL DL
  • OWL Full
OWL Lite supports those users primarily needing a classification hierarchy and simple constraints.
OWL DL supports those users who want the maximum expressiveness while retaining computational
completeness.
OWL Full meant for users who want maximum expressiveness and the syntactic freedom of RDF with no computational guarantees.


What is RDF?

Resource Description Framework(RDF) is written in XML form act as a framework for describing resources on the web. RDFis used as a general method for conceptual description or modeling of information that is implemented in web resource. RDF Use Uniform Resource Identifier(URI) to locate its resources.

Best Web Browser

What is a web browser? A browser is a software application for retrieving, presenting and traversing information resources on the World Wide Web(WWW). The best web browser may be different for each people. For me, the best web browser is Google Chrome. Google chrome consume less memory and CPU usage. This is very important to me because I am a gamer. It is my habit to open a web browser and click Facebook bookmarks before doing something with the computer. Excessive usage of memory and CPU by the web browser can cause deadly lag in my games. I only use google chrome for browsing, but for running, testing and debugging my web program, I prefer to use IE or Mozilla Firefox. IE provide more add-on support than the other web browser. For Mozilla Firefox, I like to call it Godzilla Firefox :D. Godzilla firefox provide the 'Web Developer' mode which is very useful for me to debug my program project. In brief, 'Best Web Browser' for everyone is different depending on the user usage of the browser.

About UDDI

This entry is all about Universal Description Discovery and Integration (UDDI). The existence of UDDI enables the web services to register itself in the internet and make it searchable and available. Since UDDI is a XML based registry, the directory of the web services interfaces is stored and described in WSDL. There are three parts of UDDI which is Service Registry, Service Requester and Service Provider. Service registry enable the web services to be located and published. The service requester find the appropriate services. The Service Provider is the services that contain the required operation.

ITT544 - Web Technology [Eleventh Week]

Less than a month before the lecture week end. The progress of our project is doing well. We need to improve certain part from our project due to our lecturer recommendation. Meeting with my teammates Ammar and Hasbullah on the weekend to improve the system. I still wondering how to publish our project once all the process done. It is quite challenging because I never make any web hosting before.

ITT544 - Web Technology [Tenth Week]

This update is for tenth week. It's a delayed update. On the10th week, I and my teammates have started to develop our project. The lecture and lab session going well as usual. Our project going well as we manage to cooperate effectively. We were scheduled to show our progress in the next week.
