Class Definitions
The table below is a list of classes in MeSH RDF.
| Class Name | Parent Class | Definition | Equivalent XML Data Element |
|---|---|---|---|
| meshv:AllowedDescriptorQualifierPair | meshv:DescriptorQualifierPair | A combined MeSH descriptor and qualifier, where the pairing is allowed by MeSH rules. These URIs are a mash up of the descriptor and qualifier identifiers (such as D000236Q000235). | EntryCombination/ECIN |
| meshv:CheckTag | meshv:Descriptor | A special class of descriptor singled out because they are so frequently applied to biomedical literature. There are only 2 Descriptors that are members of the class meshv:CheckTag - D005260 ‘Male’ and D008297 ‘Female’. These two Descriptors do not have tree numbers. Please see the MEDLINE Indexing Online Training Course for the complete list. | DescriptorRecord @DescriptorClass = "3" |
| meshv:Concept | N/A | MeSH concepts are meanings. Many MeSH concepts contain synonymous terms. meshv:Concept identifiers begin with ‘M’ such as M0000013 - ‘Congenital Abnormalities’. See the MeSH concept structure page for more information. | Concept |
| meshv:Descriptor * | N/A | MeSH Descriptors are a cluster of one or more concepts used to describe what a publication is about. meshv:Descriptor is the parent class of meshv:TopicalDescriptor, meshv:GeographicDescriptor, meshv:PublicationType, and meshv:CheckTag. | DescriptorRecord |
| meshv:DescriptorQualifierPair * | N/A | A combined MeSH descriptor and qualifier pair. Allowed pairs (according to MeSH rules) belong to the class meshv:AllowedDescriptorQualifierPair. Disallowed pairs belong to the class meshv:DisallowedDescriptorQualifierPair. | EntryCombination |
| meshv:DisallowedDescriptorQualifierPair | meshv:DescriptorQualifierPair | A combined MeSH descriptor and qualifier where the pairing is not allowed by MeSH rules, such as ‘Abdomen/radiography’. | EntryCombination/ECOUT |
| meshv:GeographicalDescriptor | meshv:Descriptor | A descriptor that references places or regions of the world, such as D001061 - ‘Appalachian Region’. | DescriptorRecord @DescriptorClass = "4" |
| meshv:PublicationType | meshv:Descriptor | A special class of descriptor that describes what type of publication a resource is as opposed to what it is about. All MeSH Publication Types are in the ‘V’ tree. | DescriptorRecord @DescriptorClass = "2" |
| meshv:SCR_Protocol | meshv:SupplementaryConceptRecord | MeSH protocols are therapies in the domain of cancer treatment, such as ABVD Protocol. | SupplementalRecord SCRClass="2" |
| meshv:Qualifier | N/A | Also known as Subheadings, these provide context to the use of a MeSH Heading. See heart - drug effects for an example. | QualifierRecord |
| meshv:SCR_Disease | meshv:SupplementaryConceptRecord | Rare Diseases were originally brought into MeSH from a list maintained by the Office of Rare Diseases Research. See Hepatic Fibrosis, Congenital for an example. | SupplementalRecord @SCRClass="3" |
| meshv:SCR_Chemical | meshv:SupplementaryConceptRecord | These are chemicals, drugs, enzymes, vitamins, etc., such as C011657 - ‘Andrenosterone’. | SupplementalRecord @SCRClass="1" |
| meshv:SupplementaryConceptRecord* | N/A | Supplementary Concepts are created in MeSH to aid in searching the large volume of mainly chemicals and drugs. meshv:SupplementaryConceptRecord has three sub-classes: meshv:RegularSubstance, meshv:SCR_Protocol, and meshv:SCR_Disease. | SupplementalRecord |
| meshv:Term | N/A | MeSH terms provide synonymous names for MeSH concepts. Terms have ‘T’ identifiers, and are considered either preferred or lexical variants, such as ‘Congenital Abnormalities’ as opposed to ‘Abnormality, Congenital’. | Term |
| meshv:TopicalDescriptor | meshv:Descriptor | Topical Descriptors indicate the subject of an indexed item such as a journal article. See D063926 - ‘Drug Hypersensitivity Syndrome’ for an example. | DescriptorRecord @DescriptorClass = "1" |
| meshv:TreeNumber | N/A | Tree Numbers are used to organize MeSH Descriptors in a broader-than/narrower-than manner. For example, every Descriptor treed under C04 - ‘Neoplasms’ would be about something more specific than ‘Neoplasms’. | TreeNumber |
