<!--
Transform to map content from standard xml metadata formats to
Schema.org JSON-LD for @type=Dataset. The design uses a set of
xsl variables and templates to do the mapping from the xml document
to the appropriate JSON-LD content. To configure for new metadata
scheme, update the code to extract needed information in the appropriate
variables and templates.
Note that each template has a set of variables as well.
Note that namespace delarations might need to be added on the root
stylesheet element for other metadata schemes. This transform is designed
to handle DataCiteXML
