Qualifiers comprise a set of 83 terms used to add more specificity to descriptors. Each Descriptor has a set of Allowable Qualifiers. In RDF, Descriptors and Qualifiers may be treated as separate classes, but we have also chosen to create a class of Descriptor-Qualifier pairs, each with its own URI. For example, the pairing of a Descriptor (D015242, Ofloxacin) and one of its Allowable Qualifiers (Q000008, administration & dosage) has the following URI: <a href="http://id.nlm.nih.gov/mesh/D015242Q000008" target="_blank">http://id.nlm.nih.gov/mesh/D015242Q000008</a> [ jump to <a href="#entry-combinations">entry combinations</a> ] <h3 id="class-information">Class Information</h3> In MeSH RDF, the subclasses of meshv:DescriptorQualifierPairs are: <ul> <li>meshv:AllowedDescriptorQualifierPair</li> <li>meshv:DisallowedDescriptorQualifierPair</li> </ul> <h3 id="rdf-graph-diagram">RDF Graph Diagram</h3> The following RDF graph diagram shows how descriptor-qualifier pairs are modeled. Note that the pairing (D015242Q000008, Ofloxacin/administration & dosage) is an instance of the class, meshv:AllowedDescriptorQualifierPair. Relationships between the descriptor-qualifier pair and its respective descriptor and qualifier are explicitly defined. <img src="/meshrdf/images/DQPair.png" alt="Descriptor Qualifier Pair RDF Graph
