The question “Which of the following accurately describes metadata?” was asked on Brainly.
Metadata plays a vital role in data organization, sharing, and usability by documenting key information about datasets, ensuring standardization, and improving interoperability.
Metadata is “information about information,” an innocuous-sounding term that’s more profound than one would initially assume. In short, metadata is a set of information describing, defining, or providing context for other information. It is not information itself, but what contains and facilitates knowledge regarding the information. Metadata enables digital content to be stored and discovered, and it is at the heart of applications ranging from digital libraries and databases to multimedia content and web development.
With computers, metadata is used to organize data, retrieve, manage, and maintain it in an efficient manner. It may be a document, image, webpage, or even a social media update – metadata informs us about what the data it is describing is like. For an image, metadata may be such that it has information of camera model, resolution, date and time captured, location, and even the individual who captured the image.
The Various Types of Metadata
While metadata may manifest in quite varied forms depending on data it’s describing, it can generally be categorized into three broad types: descriptive metadata, structural metadata, and administrative metadata. They all serve their own distinct role of offering user-friendly context and information about included data.
1. Descriptive Metadata
Descriptive metadata is also best identified as known metadata. Descriptive metadata is mainly used in describing data content and adding context to help with discovery. Titles, authors, keywords, subjects, and abstracts are some of the parts of descriptive metadata utilized in order to provide resources with easier identification and search capabilities.
For example, for an e-book in an e-library, its structural metadata will be its title, author, genre, publication date, ISBN number, and brief description of what the book is about. Structural metadata can be the title, author, creation date in multimedia examples like video or images.
Book: “To Kill a Mockingbird”
Author: Harper Lee
Genre: Novel
Publication Year: 1960
Summary: A novel of racial injustice in the American South.
2. Structural Metadata
Whereas descriptive metadata defines information about the data, structural metadata specifies how the data is structured and how the various components relate to each other. Structural metadata facilitates comprehension of relationships between various components of the data and navigation of large amounts of data. Structural metadata, in the majority of instances, prescribes the structure of digital objects, how various components relate to each other, and the sequence in which they are to be read or accessed.
For instance, in multimedia video or audio, structural metadata could be employed to describe the chapters or the tracks in anticipation that the user may be taken to a specific portion of the file. Structural metadata could also record the relationship between various segments (e.g., headings, images, and paragraphs) of content in a web page.
Example:
Multimedia file: Video containing multiple chapters or scenes.
Chapter 1: Introduction
Chapter 2: Main Content
Chapter 3: Conclusion
3. Administrative Metadata
Administrative metadata has a similar critical function in the administration of digital assets, their long-term preservation and maintenance. Administrative metadata addresses primarily the creation information, format, data management, access, and rights. Administrative metadata is crucial to libraries, archives, and digital repositories where many digital collections need to be managed.
Informational data supplied by administrative metadata includes the file size, resolution, file format, application to use when opening or editing the file, date last modified, and ownership or rights to the content. Such metadata provides data longevity and preservation by giving information required for best archiving as well as rights management.

The Importance of Metadata
Metadata is a unique property in information management. Metadata is beneficial for many uses, and it is simple to use, arrange, retrieve, and store data. The following sections discuss why metadata is important during the present digital age.
1. Search and Retrieval
Metadata is significant to search engines and databases since it enables efficient and effective retrieval of information. Whatever may be the research paper, image, or piece of music, users are provided with metadata as a means of ease of accessibility and retrieval of related content. The description by metadata, tags, and keywords assist in web search engine ranking of results and providing the best match to an inquiry. Likewise, in data bases and online libraries, metadata allows one to narrow down and filter queries on various parameters.
Consider how you perform a search. When you enter a query, a search engine searches through web pages’ metadata—title tags, meta descriptions, and headings—to bring back to you results that are most directly related to your query. The search would be significantly more difficult without metadata because the search engine would not know much or anything about what’s on web pages it’s crawling.
2. Facilitating Efficient Data Management Easier
Metadata is a significant factor for organizing and managing data. In providing details about the data in a systematic way, metadata facilitates grouping and sorting of information in an organized fashion. This arrangement becomes helpful where there is excess data or digital collections, and the data will be hard to handle.
For example, metadata in a content management system (CMS) can be used to set the structure of a site, and thus pages would be organized and manageable effortlessly. Likewise, metadata (file type, created date, and file name) assists one to find files readily in a file system.
3. Providing Data Protection and Long-Term Usefulness
The most significant use of metadata can be to allow that digital information to be useful in the long term. Over time, technology evolves, and formats and programs that were once current are no longer supported. Administrative metadata prevents this by including information on the file format, software required, and other details for future use. By maintaining a record of this kind of information, institutions are able to advance move or change documents into more recent forms and therefore preserve them in the long term.
Consider the procedures by which libraries and archives use metadata to preserve digital collections. When a library digitizes a published work or document, it stores metadata that explains the material (descriptive metadata), how it is arranged in its published form (structural metadata), and what preservation strategy awaits its future (administrative metadata). Thus, the content will remain usable for users in the future as technology used in preserving or delivering the content itself evolves.
4. Legal and Ethical Compliance Improvement
Aside from its technical use, metadata is also involved in legalizing and ethicalizing web content. Copyright and intellectual property rights legislation relies on metadata to track ownership, licensing contracts, and use rights of web content.
For example, an image will have embedded metadata with the author’s name as the photographer, conditions under which it may be licensed for application (e.g., commercial usage), and if attribution is to be made or not. Such information being held in the metadata, content creators and vendors will have confidence that their content is being utilized properly and lawfully.
5. Data Interoperability
The globalized world today means that information is most often drawn from a mixed variety of sources, systems, and forms. Metadata allows different systems to read and utilize the data by providing standardized descriptions of the data meaning and structure. This allows different software platforms or systems to exchange, translate, and merge data easily.
For example, metadata standards such as Dublin Core (for archives and digital libraries) or Exif (for pictures) make different systems deployed for data display, search, or storage possible so that these can communicate among themselves.
Metadata Across Domains
Metadata finds usage in several applications for diverse domains with distinct needs of saving and tracing information. Some usage of metadata for several domains are provided below:
1. Digital Archives and Libraries
Metadata enables books, journals, and other documents to be cataloged in digital libraries. Metadata records enable users to locate and retrieve content from large collections of digital material. For instance, a digital library may hold descriptive metadata on each book (author, publisher, publication date, title) and structural metadata that describes chapters and sections.
2. Multimedia Files
For multimedia content (image, video, and audio), metadata includes data about the file format, resolution, duration, artist, and copyright. For example, metadata for an image might include its size, color space, and camera settings on which it was taken. Such data is of great help in arranging and searching media material in digital collections.
3. Social Media and Web Content
Social network sites may come with related metadata, such as user-input tags, hashtags, comments, and timestamp that contribute context to the post. To give an example, metadata in a social networking site image can include location in which the photograph was taken, camera model, and any inserted text. Web pages rely upon metadata (title tags, meta descriptions) to be crawled by search engines as well as being ranked for its content.
Conclusion
Metadata is an essential component of the modern information universe. Adding context, organization, and administrative data to information, metadata makes information retrievable and searchable, stored in the long term, and harmonized with law. As more and more digital content keeps on being created, the ability to read and interact with metadata will be vital to maintaining information accessible, useful, and reliable.
From libraries and archives to multimedia and sites, the applications of metadata are immense and diverse. As more reliance is placed on digital media, understanding the significance of metadata and its role in data management will be the secret to leveraging the digital world in our interest.
