ESRA reference metadata — all experiment types
type: Dataset
description: Reference JSON-LD covering every ESRA experiment type and every field defined on the upload form. Two ways to use it: (1) Load it into the /upload page via 'Load Metadata' and delete the technique cards you don't need; or (2) give it to an LLM and ask it to produce a custom JSON-LD for YOUR experiment. Replace the example values with your own; keep 'propertyID' and 'esra:fieldKey' unchanged — ESRA maps each value to a form field by 'propertyID' (the ontology IRI) first, then 'esra:fieldKey', and only then by the human 'name' label. You may add extra parameters — see the 'esra:authorAdded' example in each block. The 'about' list holds the materials studied; they are shared by every card and load straight into the Materials Studied editor.
instructions: HOW TO USE WITH AN LLM: paste this file and say — 'Here is the ESRA metadata schema. My experiment is <TECHNIQUE> with these parameters: <your parameters>. Return a JSON-LD with only the matching hasPart block(s), keeping @context, @type, esra:experimentType and each PropertyValue name + propertyID + esra:fieldKey exactly as given, filled with my values. Add any extra parameters as PropertyValues with "esra:authorAdded": true.' Also keep the 'about' list and replace the example materials with the ones you actually studied, using only keys from 'esra:materialVocabulary'. Then download the result and load it on the ESRA upload page.
