RFC 2731 Encoding Dublin Core Metadata in HTML December 1999
The prefix "DC" precedes each Dublin Core element encoded with META,
and it is separated by a period (.) from the element name following
it. Each non-DC element should be encoded with a prefix that can be
used to trace its origin and definition; the linkage between prefix
and element definition is made with the LINK tag, as explained in the
next section. Non-DC elements, such as Email from the A-Core [AC],
may appear together with DC elements, as in
This example also shows how some special characters may be encoded.
The author name in the first element contains a diacritic encoded as
an HTML character entity reference -- in this case an accented letter
E. Similarly, the last line contains two double-quote characters
encoded so as to avoid being interpreted as element content
delimiters.
4. The LINK Tag

with the reference definition of the element set that it identifies.
A sequence of META tags describing a resource is incomplete without
one such LINK tag for each different prefix appearing in the
sequence. The previous example could be considered complete with the
addition of these two LINK tags:
