Semi-structured data is data that does not adhere to a strict schema or model, but still has some level of organization or structure. This type of data contains elements of both structured and unstructured data, as it may contain tags or metadata that provide some level of context.
Semi-structured data is commonly found in a variety of digital sources, such as XML and JSON files, log files, and social media data. It is often used for applications that require a more flexible data model, such as web applications or data generated by IoT devices.
