In software and systems engineering, a use case is a potential scenario in which a system receives an external request (such as user input) and responds to it. A use case is a list of actions or event steps typically defining the interactions between a role (known in the Unified Modeling Language (UML) as an actor) and a system to achieve a goal.

In UML, an artifact [1] is the "specification of a physical piece of information that is used or produced by a software development process, or by deployment and operation of a system." [ 1 ] "Examples of artifacts include model files, source files, scripts, and binary executable files, a table in a database system , a development deliverable ...
A system sequence diagram should be done for the main success scenario of the use case, and frequent or complex alternative scenarios. There are two kinds of sequence diagrams: Sequence Diagram (SD) : A regular version of sequence diagram describes how the system operates, and every object within a system is described specifically.
It is a common data format for storing RDF data, along with N-Triples, JSON-LD and RDF/XML. RDF represents information using semantic triples, which comprise a subject, predicate, and object. Each item in the triple is expressed as a Web URI. Turtle provides a way to group three URIs to make a triple, and provides ways to abbreviate such ...
The purpose of the UI design draft is to show the design proposed, and to explain how the user interface enables the user to complete the main use cases, without going into details. It should be as visual as possible and all the material created must be in such a format that it can be used in the final UI specification.

The specification was written up as an IETF draft by John Kunze in December 2008, where it has seen several revisions before being issued as an RFC. [2] In 2009, the Library of Congress produced a video that describes the specification and the use cases around it. [4] [5] In 2018, version 1.0 was published as an RFC by the Internet Engineering ...
