microbe

METPO:1000525 · CLASS · REVIEWED

A material entity that is too small to be viewed by the unaided eye, typically requiring microscopy for observation. Used as the domain class for METPO organism-to-X object properties so that organism-level assertions can be expressed as `<microbe-instance> <METPO predicate> <object-class>`.

Curation history

  1. · CREATED_UPPER_CLASS_RECORD · claude

    Created upper-ontology CLASS record for METPO:1000525 (microbe) so that the domain of un-deprecated metabolism OBJECT_PROPERTYs (which all declare domain https://w3id.org/metpo/1000525) resolves to a curated TraitMech record.

  2. · REMOVED_NON_EQUIVALENT_XREF · claude

    Removed xref to OBI:0100026 (organism) per Copilot review of PR #55. The schema documents xrefs as ontology *equivalents*; OBI:0100026 "organism" is broader than "microbe" (it covers macro-organisms too), so treating it as an equivalence mapping would mis-align downstream consumers. No clean NCBITaxon, OBI, or ENVO equivalent for "microbe" exists because the concept cuts across bacteria, archaea, and microbial eukaryotes; left without xrefs.
