Can the copyrightMD XML be used with or imported into other XML schemas?
Yes. In fact, we assume that it will be used in conjunction with other metadata. For example, a copyrightMD record could be combined with other descriptive (e.g., Dublin Core, Metadata Object Description Schema (MODS), or MARCXML), structural, administrative, and technical metadata records in a METS wrapper. Our main interest is in the data elements of copyrightMD, and these could presumably be expressed in formats other than XML schema. If you do use the data elements in other formats, please let us know so we can add your implementation to our web site.
