HTTP Interfaces

To communicate with the Metadata Service a set of HTTP interfaces is available, which will be described in this section. The HTTP interfaces will be used by other applications, and not by end-users in their web browser. The HTTP interface for the web browser will probably be very similar as far as URL's goes.

What exactly is a HTTP interface? It basically boils down to having a set of URL-addressable resources, on which a limited number of operations are supported (mostly GET and POST), and which return as result of that operation a representation of the resource. The description of the HTTP interface will thus mostly consist of identifying the set of resources (and their URL's), the operations that are allowed on it, and the resulting representations.

The HTTP interfaces of the Metadata Web Application provided are to search, manage, and access the metadata objects served by Metadata Registry and Resource Registry. Details regarding the specifics can be found in the links below.
