Types of software metadata

There are various types of software metadata that provide different types of information about a software product. They can be broadly categorized into three main types:

1. Descriptive metadata

Descriptive software metadata plays a crucial role in providing information about the purpose, functionality, and features of a software product. It serves as a summary or detailed description that helps both users and developers comprehend the software's capabilities.

However, it's important to note that the decision to provide this metadata lies with the developers, and in some cases, they may choose not to disclose it.

Descriptive metadata examples

Descriptive software metadata typically includes the following information:

  • Software name: The name or title of the software, which serves as an identifier.
  • Summary: A brief overview or summary that highlights the main purpose or functionality of the software.
  • Detailed description: A more comprehensive description that provides in-depth information about the software, its key features, and its intended use cases. This description may cover various aspects such as the software's core functionality, user interface, performance characteristics, and integration capabilities.
