One of the main goals of the CEDAR project is to build an infrastructure for the creation and storage of machine-readable metadata templates. Metadata templates provide detailed definitions of the metadata that describes a particular data resource. For example, a single study instance that produces a data set (the data resource) may be described with metadata in a comma-separated values (CSV) file. The metadata template describes what is in that CSV file, and applies to other CSV files following the same specification.
This report describes the format of the templates, elements, and instances that make up the CEDAR metadata framework. The specification allows CEDAR metadata to be used by CEDAR, and exchanged with other metadata systems.
We also have written a paper describing the model, which provides a more formal written description but has less technical detail.
