1. The web as a platform for building distributed systems
Thinking in Resources
Basically most of the things in Internet is a resource, a document, a movie, a song, or a representation of something in the "real world".
Resource identifiers
In order to access a resource in the web is through a URI (Uniform Resource Identifier). The relation between resources and URI's is:
- one to many
Meaning that one resource can be accessed by many URL's.
| Term | Comments |
|---|---|
| URI [Uniform Resource Identifier] | Standard way to access web resources through the browser |
| IRI (International Resource Identifier) | This is an update to the definition of URI to allow the use of international characters |
| URN (Uniform Resource Name) | This is a URI with "urn" scheme, used to convey unique names in a particular "namespace". |
| URL (Uniform Resource Locator) | It is a URI's sort of accesor used to convey information about the way in which one interacts with the identified resource. |
| Address | Many think of resources as having "addresses" on the web. |
