Schema.org hierarchy

This is a new Type that fits into the schema.org hierarchy as follows:
Thing > BioChemEntity > ChemicalSubstance

Description

A chemical substance is 'a portion of matter of constant composition, composed of molecular entities of the same type or of different types' (source: ChEBI:59999).

Key to specification table
  • Green properties/types are proposed by Bioschemas, or indicate proposed changes by Bioschemas to Schema.org
  • Red properties/types exist in the core of Schema.org
  • Blue properties/types exist in the pending area of Schema.org
  • Black properties/types are reused from external vocabularies/ontologies
PropertyExpected TypeDescription
Properties from ChemicalSubstance
chemicalComposition Text The chemical composition describes the identity and relative ratio of the chemical elements that make up the substance.
chemicalRole DefinedTerm A role played by the BioChemEntity within a chemical context.
potentialUse DefinedTerm Intended use of the BioChemEntity by humans.
Properties from BioChemEntity
associatedDisease MedicalCondition  or
PropertyValue  or
URL 
Disease associated to this BioChemEntity. Such disease can be a MedicalCondition or a URL. If you want to add an evidence supporting the association, please use PropertyValue.
bioChemInteraction BioChemEntity A BioChemEntity that is known to interact with this item.
bioChemSimilarity BioChemEntity A similar BioChemEntity, e.g., obtained by fingerprint similarity algorithms.
biologicalRole DefinedTerm A role played by the BioChemEntity within a biological context.
hasBioChemEntityPart BioChemEntity Indicates a BioChemEntity that (in some sense) has this BioChemEntity as a part.
Inverse property: isPartOfBioChemEntity.
hasMolecularFunction DefinedTerm  or
PropertyValue  or
URL 
Molecular function performed by this BioChemEntity; please use PropertyValue if you want to include any evidence.
hasRepresentation PropertyValue  or
Text  or
URL 
A common representation such as a protein sequence or chemical structure for this entity. For images use schema.org/image.
isEncodedByBioChemEntity Gene Another BioChemEntity encoding by this one.
Inverse property: encodesBioChemEntity.
isInvolvedInBiologicalProcess DefinedTerm  or
PropertyValue  or
URL 
Biological process this BioChemEntity is involved in; please use PropertyValue if you want to include any evidence.
isLocatedInSubcellularLocation DefinedTerm  or
PropertyValue  or
URL 
Subcellular location where this BioChemEntity is located; please use PropertyValue if you want to include any evidence.
isPartOfBioChemEntity BioChemEntity Indicates a BioChemEntity that is (in some sense) a part of this BioChemEntity.
Inverse property: hasBioChemEntityPart.
taxonomicRange DefinedTerm  or
Taxon  or
Text  or
URL 
The taxonomic grouping of the organism that expresses, encodes, or in someway related to the BioChemEntity.
Properties from Thing
additionalType URL An additional type for the item, typically used for adding more specific types from external vocabularies in microdata syntax. This is a relationship between something and a class that the thing is in. In RDFa syntax, it is better to use the native RDFa syntax - the 'typeof' attribute - for multiple types. Schema.org tools may have only weaker understanding of extra types, in particular those defined externally.
alternateName Text An alias for the item.
description Text A description of the item.
disambiguatingDescription Text A sub property of description. A short description of the item used to disambiguate from other, similar items. Information from other properties (in particular, name) may be necessary for the description to be useful for disambiguation.
identifier PropertyValue  or
Text  or
URL 
The identifier property represents any kind of identifier for any kind of Thing, such as ISBNs, GTIN codes, UUIDs etc. Schema.org provides dedicated properties for representing many of these, either as textual strings or as URL (URI) links. See background notes for more details.
image ImageObject  or
URL 
An image of the item. This can be a URL or a fully described ImageObject.
mainEntityOfPage CreativeWork  or
URL 
Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See background notes for details.
Inverse property: mainEntity.
name Text The name of the item.
potentialAction Action Indicates a potential Action, which describes an idealized action in which this thing would play an 'object' role.
sameAs URL URL of a reference Web page that unambiguously indicates the item's identity. E.g. the URL of the item's Wikipedia page, Wikidata entry, or official website.
subjectOf CreativeWork  or
Event 
A CreativeWork or Event about this Thing.
Inverse property: about.
url URL URL of the item.
