Experiment Model¶

The Experiment model is used to describe a physical, non-computational process, such as a wet-lab experiment. It captures key details about the experimental setup, including the instruments and samples used, and links to the data it generated.

Properties¶

Property	Type	Description	Required
`guid` (alias: `@id`)	`str`	The unique, resolvable identifier for the Experiment. Should be an ARK.	Yes
`name`	`str`	A human-readable name for the experiment.	Yes
`experimentType`	`str`	The type of experiment performed (e.g., "Immunofluorescence Staining", "SEC-MS").	Yes
`runBy`	`str`	The person, lab, or organization that performed the experiment.	Yes
`description`	`str`	A detailed description of the experimental protocol and purpose (min 10 characters).	Yes
`datePerformed`	`str`	The date the experiment was performed, in ISO 8601 format.	Yes
`metadataType` (alias: `@type`)	`Optional[str]`	The schema.org type. Defaults to `https://w3id.org/EVI#Experiment`.	No
`associatedPublication`	`Optional[str]`	A URL or citation for a publication that describes this experiment.	No
`protocol`	`Optional[str]`	A URL pointing to a detailed experimental protocol.	No
`usedInstrument`	`Optional[List[IdentifierValue]]`	A list of links (by `@id`) to the `Instrument` entities used.	No
`usedSample`	`Optional[List[IdentifierValue]]`	A list of links (by `@id`) to the `Sample` entities used.	No
`usedTreatment`	`Optional[List[IdentifierValue]]`	A list of links (by `@id`) to `BioChemEntity` entities applied as treatments.	No
`usedStain`	`Optional[List[IdentifierValue]]`	A list of links (by `@id`) to `BioChemEntity` entities used as stains.	No
`generated`	`Optional[List[IdentifierValue]]`	A list of links (by `@id`) to the `Dataset` entities produced by this experiment.	No
