    dcterms:description       """This metric evaluates whether the identifier provided as input 
    satisfies the EOSC-PID aligned FAIRsharing definition of global uniqueness.
<p/>Why should we measure it?
<p/>FAIR Principle F1 requires that metadata be assigned a globally unique, 
    persistent and resolvable identifier. This metric is particularly concerned 
    with the globally uniqueness aspect of GUPRIs; 
        global uniqueness is required to prevent identifier collision across institutions, 
            systems and domains. Otherwise, an identifier shared by multiple resources 
            will confound efforts to describe that resource, or to use the identifier to 
            retrieve it. In this metric, the definition of global uniqueness follows 
            the FAIRsharing guidance on Globally Unique, 
                Persistent and Resolvable Identifier (GUPRI) schemas. 
            This guidance requires that the identifier schema must use a 
            controlled syntax/namespaces to avoid clashes; such syntax/namespaces must be 
            governed by clearly defined Authorities. If there is any way the identifier 
            could be created as part of another identifier system (e.g. if it 
            is a structured series of alphanumeric characters such as P12345 (UniProt Accession Number) 
            that could theoretically be used for other identifiers) 
            then it is not globally unique. To fulfil this requirement in practice,
                 it generally (but not always) requires a URL prefix of some kind. 
                This metric evaluates whether the identifier provided as input 
                satisfies the FAIRsharing definition of global uniqueness. The 
                evaluation assesses whether the identifier schema operates 
                within a governed namespace that prevents external collision 
                and ensures unambiguous interpretation beyond the local database context.
