meta- layer repositories

Meta-layer repositories are collections of information that provide an organized overview of data from various sources. Think of them as a library catalog that not only lists books but also summarizes their contents, making it easier to find and understand a topic quickly. In the context of general knowledge, these repositories gather, categorize, and reference information across multiple subjects, allowing users to access a wealth of knowledge without needing to dig through each source individually. They enhance our understanding by presenting interconnected information in a structured manner.
