The Semantic Web, or Web 3.0 as it also known, is allowing for the internet to become a way for data to be linked for ease of access across the world. What this next evolutionary step for the internet does, is allows for information that is available and makes it connected through ontological connections.
Tim Berners-Lee refers to the Semantic Web as the next stage for the internet, and will aid researchers in their quest to find cures for diseases, make it easier for quick responses to natural disasters and other problems, through the way the data is connected, and how it is retrieved. He compares the time since the release of the Semantic Web, to that of the internet when it was first released, and these RDF documents are as meaningful to the Semantic Web, as HTML is to the document web. People were unsure of it and did not know what to make of it, however it has an exponential potential that increases as people gain the understanding of what Web 3.0 is capable of. The two biggest websites in the world have already introduced this to what they deliver on an everyday basis.
The Google Social Graph Application Programming Interface (API) uses the information that is readily available, and through the use of XHTML Friends Network or XFN for short, and FoaF (Friend of a Friend) links this information can be sorted in a way that allows for the connection of accounts from the same user and their friends lists can show up on other connected networks so the internet knows the other handles for this person through connections of their websites, or social networking sites. The Facebook social graph API works the same way as the Google API, and has a section on Facebook that allows for web developers to show, edit and create connections through nodes with identifiers in the graph.
If the inventor of the World Wide Web, and the two largest websites on the internet are excited about this next step in connecting data in a meaningful way, then I suggest that it is as Tim Berners-Lee puts it, ” …With this sea of data, we will just be able to solve problems that we were not able to solve before…”
