Zun=C3=A4chst werden hier zwei existierende Beispiele aufgezeigt, wie ma= n die Frage beantworten kann. Beide L=C3=B6sungen sind sehr =C3=A4hnlich un= d benutzen einen Blank Node.
Beispiel:
In worldcat.org wird eine Mischung aus dem schema.org-Vokabular und SKOS= verwendet:

Die Erweiterung f=C3=BCr health/medical types in schema.org (Dokumentation in Englisch) wird unter anderem benutzt, um= den medizinischen Code (z.B. MeSH) mit Microdata-Markup anzugeben.
Microdata-Beispiel (von http://schema.org/MedicalGuidelin= e):
<spa= n itemprop=3D"about" itemscope itemtype=3D"http://schema.org/Drug"> <span itemprop=3D"name">Metformin</span> <span itemprop=3D"code" itemscope itemtype=3D"http://schema.org/MedicalCode" itemid=3D"http://www.ncbi.nlm.nih.gov/mesh/D02.078.370.141.450"&g= t; <!-- Note: use of itemid is not mandatory, but recommended when an external enumeration is available --> <meta itemprop=3D"code" content=3D"D02.078.370.141.450"/> <meta itemprop=3D"codingSystem" content=3D"MeSH"/> </span>
Mehr Beispiele gibt es unter http://schema.org/MedicalCondi= tion und http://schema.org/MedicalScholarlyArticle<= /a>.
Angelehnt an die beiden betrachteten Beispiele, k=C3=B6nnten wir folgend= e L=C3=B6sung vorschlagen:

An annotation is considered to be a set of connected resources, typicall= y including a body and target, and conveys that the body is related to the = target. The exact nature of this relationship changes according to the inte= ntion of the annotation, but most frequently conveys that the body is someh= ow "about" the target. Other possible relationships include that th= e body is an identifier for the target, provides a representation = of the target, or classifies the target in some way.
