4.1 Terms and definitions

For the purposes of this standard the following terms have the definitions specified in this clause. Although all the terms below are capitalised, they appear in the text of this standard in lower case, for ease of readability.

Web Service

A modern set of web technologies that enable small pieces of information, typically in the form of XML files, to be exchanged. Augmented with (S)FTP (or other cloud-based storage mechanisms) they can be used to communicate AR standard messages as well as supplementary documents referenced from such messages along the digital music value chain.

Web Service Call

The sending of an XML document to a port/address on a web server, using HTTP or HTTPS.

Web Service Response

The sending of an XML document in direct response to a web service call, using HTTP or HTTPS. For the avoidance of doubt, the appropriate response is always the message indicated in the appropriate choreography.
