DefinedTerm
A word, name, acronym, phrase, etc. with a formal definition. Often used in the context of category or subject classification, glossaries or dictionaries, product or creative work types, etc. Use the name property for the term being defined, use termCode if the term has an alpha-numeric code allocated, use description to provide the definition of the term.

Properties from DefinedTerm
| Property | Expected Type | Description |
|---|---|---|
| inDefinedTermSet | DefinedTermSet, URL | A DefinedTermSet that contains this term. |
| termCode | Text | A code that identifies this DefinedTerm within a DefinedTermSet. |
Properties from Thing
| Property | Expected Type | Description |
|---|---|---|
| additionalType | Text, 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. Typically the value is a URI-identified RDF class, and in this case corresponds to the use of rdf:type in RDF. Text values can be used sparingly, for cases where useful information can be added without their being an appropriate schema to reference. In the case of text values, the class label should follow the schema.org style guide. |
| alternateName | Text | An alias for the item. |
| description | TextObject, 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, URL, Text | 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, URL | An image of the item. This can be a URL or a fully described ImageObject. |
| mainEntityOfPage | URL, CreativeWork | Indicates a page (or other CreativeWork) for which this thing is the main entity being described. See background notes for details. |
| 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, Event | A CreativeWork or Event about this Thing. |
| url | URL | URL of the item. |
Instances of DefinedTerm may appear as a value for the following properties
| Property | On Types | Description |
|---|---|---|
| assesses | CreativeWork, EducationEvent, LearningResource | The item being described is intended to assess the competency or learning outcome defined by the referenced term. |
| biologicalRole | BioChemEntity | A role played by the BioChemEntity within a biological context. |
| certificationIdentification | Certification | Identifier of a certification instance (as registered with an independent certification body). Typically this identifier can be used to consult and verify the certification instance. See also gs1:certificationIdentification. |
| chemicalRole | ChemicalSubstance, MolecularEntity | A role played by the BioChemEntity within a chemical context. |
| competencyRequired | LearningResource, EducationalOccupationalCredential | Knowledge, skill, ability or personal attribute that must be demonstrated by a person or other entity in order to do something such as earn an Educational Occupational Credential or understand a LearningResource. |
| creativeWorkStatus | CreativeWork | The status of a creative work in terms of its stage in a lifecycle. Example terms include Incomplete, Draft, Published, Obsolete. Some organizations define a set of terms for the stages of their publication lifecycle. |
| educationalLevel | LearningResource, CreativeWork, EducationEvent, EducationalOccupationalCredential | The level in terms of progression through an educational or training context. Examples of educational levels include 'beginner', 'intermediate' or 'advanced', and formal sets of level indicators. |
| educationalUse | LearningResource, CreativeWork | The purpose of a work in the context of education; for example, 'assignment', 'group work'. |
| expressedIn | Gene | Tissue, organ, biological sample, etc in which activity of this gene has been observed experimentally. For example brain, digestive system. |
| financialAidEligible | EducationalOccupationalProgram, Course | A financial aid type or program which students may use to pay for tuition or fees associated with the program. |
| hasDefinedTerm | Taxon, DefinedTermSet | A Defined Term contained in this term set. |
| hasMolecularFunction | BioChemEntity | Molecular function performed by this BioChemEntity; please use PropertyValue if you want to include any evidence. |
| industry | JobPosting | The industry associated with the job position. |
| isInvolvedInBiologicalProcess | BioChemEntity | Biological process this BioChemEntity is involved in; please use PropertyValue if you want to include any evidence. |
| isLocatedInSubcellularLocation | BioChemEntity | Subcellular location where this BioChemEntity is located; please use PropertyValue if you want to include any evidence. |
| learningResourceType | LearningResource, CreativeWork | The predominant type or kind characterizing the learning resource. For example, 'presentation', 'handout'. |
| measurementMethod | DataDownload, PropertyValue, DataCatalog, Observation, StatisticalVariable, Dataset | A subproperty of measurementTechnique that can be used for specifying specific methods, in particular via MeasurementMethodEnum. |
| measurementTechnique | DataCatalog, Observation, StatisticalVariable, Dataset, DataDownload, PropertyValue | A technique, method or technology used in an Observation, StatisticalVariable or Dataset (or DataDownload, DataCatalog), corresponding to the method used for measuring the corresponding variable(s) (for datasets, described using variableMeasured; for Observation, a StatisticalVariable). Often but not necessarily each variableMeasured will have an explicit representation as (or mapping to) an property such as those defined in Schema.org, or other RDF vocabularies and "knowledge graphs". In that case the subproperty of variableMeasured called measuredProperty is applicable. The measurementTechnique property helps when extra clarification is needed about how a measuredProperty was measured. This is oriented towards scientific and scholarly dataset publication but may have broader applicability; it is not intended as a full representation of measurement, but can often serve as a high level summary for dataset discovery. For example, if variableMeasured is: molecule concentration, measurementTechnique could be: "mass spectrometry" or "nmr spectroscopy" or "colorimetry" or "immunofluorescence". If the variableMeasured is "depression rating", the measurementTechnique could be "Zung Scale" or "HAM-D" or "Beck Depression Inventory". If there are several variableMeasured properties recorded for some given data object, use a PropertyValue for each variableMeasured and attach the corresponding measurementTechnique. The value can also be from an enumeration, organized as a MeasurementMetholdEnumeration. |
| pattern | Product, CreativeWork | A pattern that something has, for example 'polka dot', 'striped', 'Canadian flag'. Values are typically expressed as text, although links to controlled value schemes are also supported. |
| physicalRequirement | JobPosting | A description of the types of physical activity associated with the job. Defined terms such as those in O*net may be used, but note that there is no way to specify the level of ability as well as its nature when using a defined term. |
| potentialUse | ChemicalSubstance, MolecularEntity | Intended use of the BioChemEntity by humans. |
| programType | EducationalOccupationalProgram | The type of educational or occupational program. For example, classroom, internship, alternance, etc. |
| pronouns | Person | A short string listing or describing pronouns for a person. Typically the person concerned is the best authority as pronouns are a critical part of personal identity and expression. Publishers and consumers of this information are reminded to treat this data responsibly, take country-specific laws related to gender expression into account, and be wary of out-of-date data and drawing unwarranted inferences about the person being described. In English, formulations such as "they/them", "she/her", and "he/him" are commonly used online and can also be used here. We do not intend to enumerate all possible micro-syntaxes in all languages. More structured and well-defined external values for pronouns can be referenced using the StructuredValue or DefinedTerm values. |
| sensoryRequirement | JobPosting | A description of any sensory requirements and levels necessary to function on the job, including hearing and vision. Defined terms such as those in O*net may be used, but note that there is no way to specify the level of ability as well as its nature when using a defined term. |
| size | CreativeWork, Product | A standardized size of a product or creative work, specified either through a simple textual string (for example 'XL', '32Wx34L'), a QuantitativeValue with a unitCode, or a comprehensive and structured SizeSpecification; in other cases, the width, height, depth and weight properties may be more applicable. |
| teaches | CreativeWork, EducationEvent, LearningResource | The item being described is intended to help a person learn the competency or learning outcome defined by the referenced term. |
| valueReference | PropertyValue, QuantitativeValue, QualitativeValue | A secondary value that provides additional information on the original value, e.g. a reference temperature or a type of measurement. |
| variesBy | ProductGroup | Indicates the property or properties by which the variants in a ProductGroup vary, e.g. their size, color etc. Schema.org properties can be referenced by their short name e.g. "color"; terms defined elsewhere can be referenced with their URIs. |
