| CHD PAR SIB |
(no rela) | Represent the hierarchy as created from the values in the <TreeNumber> tags in dmesh and qmesh. Official MeSH xml release files do not include the top levels of a hierarchy, so additional top level concepts are created and maintained in separate files. | desc*.xml qual*.xml |

Connect descriptors with allowable qualifiers. Extracted from the <AllowableQualifiersList> tag in desc*.xml | desc*.xml |

Hierarchy (MRHIER):
)The hierarchy is created from values in the <TreeNumber> tags in desc*.xml and qual*.xml. Official MeSH xml release files do not include the top levels of a hierarchy, so additional top level concepts are created and maintained in separate files.
Mappings (MRMAP):
)No mappings are represented for MeSH.
