Uri URL urn

Let's do some science.

URI: Uniform Resource Identifier (Uniform Resource Identifier). the resource name placed on the server becomes the Uniform Resource identifier. An information resource that can be uniquely identified and positioned on the internet.

URL: Uniform Resource Locator . A URL is the most common form of a URI that describes a specific location of a specific resource on a particular server. You can clearly explain how to get resources from a precise, fixed location.

The form is as follows:http://www.test.com/hello.c

urn: .urn " Span style= "font-family: the song Body;" > is the uri another form. is still in the development stage, compared with the url , urn url compared with some advantages, For example, a resource exists in a form unrelated to a specific server. The direct point is that even if the resources are randomly moved positions will not occur like the traditional url form occurs when the 404 urn can be vigorously promoted, will be able to greatly improve the current information released by the various wonderful phenomenon.

The form is as follows: urn:ietf:rfc:2141 This allows you to find resources directly by name. You can also move resources at will.

We can know that theURI contains two forms, one is the URL, is our most common form, there is a urn, but still in the development stage.

What we want to understand is that the advantage of the URL is that the acceptance is large and the scope of use is wide, and it has become a kind of information publishing method that almost everyone will use. However, there are some limitations of its own, as if the resources are moved randomly, it will cause problems. This time can reflect the urn 's advantages, that is, the resource and resource location of the independence. If you can fully use the urn of this feature, it will be able to make the information distribution becomes more convenient. But the current dilemma is that the urn is still in the experimental stage, and there is no widespread use. Even if the search for the relevant information is less pathetic. Because of the characteristics of the urn, it is necessary to use a special parsing method to parse the location of the resource. However, such a special structure has affected the adoption of this method of progress. Nevertheless, we can look into the future and wait until the urn is widely used, and we will be able to find the resources more convenient and have more choices.
