Embodiments are provided to manage information associated with a number of disparate information sources. In an embodiment, a system includes a data structure having a uniform metadata representation and a metadata handler for interacting with the data structure. The data structure can be associated with an underlying file or some other type of information source. In one embodiment, a number of handlers can be chained together to extract and return information according to a desired mode of operation. The embodiments provide extensibility and can be tailored according to a desired implementation. Other embodiments and implementations are available.
