Anmerkung

idno sollte für Identifikatoren genutzt werden, die ein Objekt oder Konzept in einem formalen Katalogsystem wie z. B. einer Datenbank oder einem RDF store oder in einem verteilten System wie dem World Wide Web eindeutig identifizieren. Als Werte für type von idno bieten sich z. B. die ISBN, die ISSN, ein DOI oder ein URI an.
Beispiel
<idno type="ISBN">978-1-906964-22-1</idno>
<idno type="ISSN">0143-3385</idno>
<idno type="DOI">10.1000/123</idno>
<idno type="URI">http://www.worldcat.org/oclc/185922478</idno>
<idno type="URI">http://authority.nzetc.org/463/</idno>
<idno type="LT">Thomason Tract E.537(17)</idno>
<idno type="Wing">C695</idno>
<idno type="oldCat">
 <g ref="#sym"/>345
</idno>

In the last case, the identifier includes a non-Unicode character which is defined elsewhere by means of a glyph or char element referenced here as #sym.
Beispiel
<idno type="ISBN">978-1-906964-22-1</idno>
<idno type="ISSN">0143-3385</idno>
<idno type="DOI">10.1000/123</idno>
<idno type="URI">http://www.worldcat.org/oclc/185922478</idno>
<idno type="URI">http://authority.nzetc.org/463/</idno>
<idno type="LT">Thomason Tract E.537(17)</idno>
<idno type="Wing">C695</idno>
<idno type="oldCat">
 <g ref="#sym"/>345
</idno>

In letztgenanntem Fall enthält der Identifikator ein Nicht-Unicode-Zeichen, das an anderer Stelle mit Hilfe eines glyph oder char-Elements definiert ist und hier als #sym referenziert wird.
