Dublin Core is a way of describing things, like a book or a picture, so that other people can easily understand what the thing is about. It's like using words to give someone a really good idea of what something is, without them having to see it themselves.
Imagine you have a book. You can use Dublin Core to describe the book by giving it a title, author, and a brief description of the story. This way, when someone else is looking for a book to read, they can search for books by the title, author, or description, and easily find your book.
Dublin Core helps people organize and find information on the internet. It's like having a library where every book has a tag that says what it's about, so you can easily find it on the shelf. This way, people can find what they're looking for faster and more easily without having to sift through a bunch of information that isn't relevant to them.
Overall, Dublin Core is a tool that makes it easier for people to understand and find information on the internet by using simple descriptions.
