Resource Description Framework (RDF)
RDF stands for Resource description framework. We can define RDF as “RDF is a model/standard with the help of which we can define resources on the web”. The common people don’t understand RDF. It is developed to understand and read by computer.RDF is a base for managing metadata. With the help of RDF, we can exchange information between applications, operating systems, and computers on the internet. We can define any information of different web pages with the help of RDF.
History of RDF
There are different forefathers of RDF. The first who defined RDF was MCF a project started by Ramanthan V.Guha at apple computer between 1995 and 1997.he left the apple computer and joins Netscape and start working with Tim Brey on MCF to employ XML to produce first version of RDF. In 1999, RDF was defined by W3C to create RDF Data model by using XML.In2004, work on RDF is continued and produces a group of related specification. The W3C continued to work on RDF data model defined in 1999 and continue to develop new and improved specifications.W3C arrange a workshop in 2010 to discuss with their members the changes and improvements in RDF.

The Resource Description Framework (RDF) is a language that is used to represent information about Web resources. RDF is intended for situations in which this information is processed by applications, rather than being displayed to users. RDF provides a common framework for expressing this information so that it can be exchanged between applications without loss of meaning. Since it is a common framework, application designers can take advantage of the availability of common RDF parsers and processing tools. The ability to exchange information betw...

RDF Data Model
We can represent RDF data model with the help of 3 types of object
• Resource
• Property
• Statement
Resources
A resource can be anything or object that can be represented by uniform resource identifier. Resources contain properties like attributes or characteristics. Resource may be a picture, document, or paragraph on the internet.
Property
Property is used to describe resources that contain a name, relation, attribute and character of any object.
Property Value
Is the value of a property. A property value can be a resource.
Statement
A statement is a collaboration of a resource, property and property value. Properties of different resources can be explained by statements.
As pointed out by Professor C.B. Macpherson (Essential Reading Handout p.5), property can be seen as a political relation between people. A relation that is, unlike marriage or contracts, relatively hard to get into and leave. These can include new property such as a job or a group of friends. This creates a power relation between the people and the thing (between subject and an object). Therefore the statement ‘Property is a power relationship between people’ is true but it would be better if we portrayed it as a relationship between people with regard to things.
Conceptual schema at the conceptual level describes the structure and constraints for the whole database for a community of users. These uses a conceptual or an implementation data model.
To put it another way, properties are what make up an object, and substance is what the
Abstract. Recent frameworks employ the strategy to define a specific metadata schema for applications to use in their classes and programming elements, enabling framework behavior customization. Despite this technique is being widely used, there are not models, design patterns or development guidelines that aim to help in the creation of this kind of framework. This thesis proposes a conceptual model for metadata-based frameworks that has the aim to identify appropriate solutions for its internal structure and scenarios where it is suitable for. As a result, software architects and framework developers with this conceptual model should be able to identify situations where the metadata usage is appropriate and to design suitable solutions that provides flexibility in metadata reading and processing.
Technologies advance so quickly that it seems no sooner has one technology become widely accepted than it is replaced by something newer and superior. Technologies in the field of web design are no exception. As web-related hardware and software components became faster, more reliable, and easier to use, the web exploded with new websites which led to a dramatic increase in web usage around the world.
Hypertext allows markets to meet their audience's needs in very specific ways. For example, Ford Motor Company may have a site on the web devoted to the 1999 Ford Mustang. With the use of hyperlinks, Ford can provide detailed information about the car's warranty on a separate site. People who are interested in knowing m...

For the last 10 years the web has reinvented itself. Moving from static HTML pages filled with information to interactive information portals, where massive amounts of people contribute to improve each other and spread knowledge.
Metadata has many functions which help facilitate the use of resources within the library’s collection. The function of metadata help summarize the meaning of the data, retrieve and use copies of the data, gives history of the data, shows where to find data, and shows relationships between data sets. Liu states that there are five specific functions which metadata supports: description, location, discovery, archivi...

Ontologies: show the key element in WSMO, offers common terminology used by other WSMO elements and also describe the semantic properties of relations, concepts and set of axioms.
The geographic information is converted into linked geospatial data, for exposing, sharing and connecting resources in the web. For example, a geographical feature described in the data has a URI with links pointing to other geographical features based on their geospatial relation. The knowledge model and catalogue model of the datasets (metadata) is changed according to the developments in the field of semantic web to accommodate details that are necessary for pattern recognition and subsequent linking .The SDI should use open data...
Developing Web contents involves shaping and making many choices involving technical, aesthetic, and usability concerns. With the expanding technical options for communication on the World Wide Web, it is tempted to focus only on issues such as hypertext markup language (HTML) syntax, page layout, or the latest and flashiest technologies. However, there needs to be a broader approach in order to articulate the information content that is to be conveyed. There is also a need to pay attention to the characteristics and qualities of the Website as a medium for communication so that there are not merely duplicate practices intended for paper and other media.
Web sites have progressed to a new level of sophistication. They have a ability to track and store usage patterns and allow use for of this information in the development of advertisement and focus for both the Web page and their connected database (Mendelson, 98).There has been a development of dynamic Web sites because static Web pages were becoming, in a way, an older style. The new trends of Web design require more interactive and exciting ways to interest the user in the Web page. Web sites must also be able to provide companies with the most up-to-date information or data that is graphically appealing, yet will not leave any uncertainty or vague impressions on the consumers part. One way that companies have been working on making Web pages more interactive is enhancing methods that they already have created. For example, dynamic hypertext mark-up language (DHTML) was created for the use of dynamic sites, such as Java applets and ActiveX. These forms have been recognized as means of maintaining standard equality throughout the development proce...
The introduction of World Wide Web (WWW) has make this problem of digital information sharing become more crucial and also leading to the information explosion and overload. It is hard to define whether the digital information shared on the World Wide Web or the internets are the right or true information produce by the person who has the specialty in that field of information he or she produces or not.
