meta content framework (MCF)
The Meta Content Framework (MCF) is an Apple technology from the 90s, which was replaced by the Resource Description Framework( RDF).
As a file format, the Meta Data Format (MCF) is a cross- platform data format that can be used to represent unstructured data sets in a structured manner. With this framework, the World Wide Web(WWW) should appear more as an ordered library than as an unordered collection of books and information.
The Meta Content Framework is a tool that provides information about information by assigning properties to objects. Different data from different databases can be represented using the MCF framework.
