Each CMDI files consists of 3 parts:
- a (fixed) Header, containing administrative information:
- MdCreator: the author of the file
- e.g. “Eric Carlson”
- MdCreationDate: the creation date of this file
- e.g. “2016-12-31”
- MdSelfLink: the URL or PID of this file
- e.g. “https://www.institute.org/metadata/record.cmdi” or “hdl:1234/00-1234-5678-9ABC” (alternatively “https://hdl.handle.net/1234/00-1234-5678-9ABC”)
- MdProfile: the unique identifier of a CMDI profile, as generated by the component registry
- e.g. “clarin.eu:cr1:p_1290431694484”
- MdCollectionDisplayName: an (optional but recommended) plain text indication to which collection this file belongs. Used for the Collection facet in the VLO
- MdCreator: the author of the file
- a (fixed) Resources section, containing links to:
- external files (e.g. an annotation file or a sound recording)
- and/or other CMDI metadata files (to build hierarchies)
- a (flexible) Components section, where the actual components that this profile contains will appear
This example CMDI file illustrates the use of the 3 parts.
