| description | NCI Metathesaurus (NCIM) property codes reference guide for filtering and searching concepts in the EVS API |
This skill provides detailed information about NCI Metathesaurus (NCIM) property codes that can be used when searching and filtering concepts in the NCI EVS API.
Properties in NCIM are attributes that provide additional information about concepts from the NCI Metathesaurus, which integrates multiple source vocabularies. When using the search_concepts tool, you can filter results by specific properties using the property parameter along with the value parameter.
Important: These properties can only be used when terminology is set to 'ncim'.
Properties are organized into logical categories for easier reference:
