Convert to LinkML schema

[sbliven]

Description

LinkML is a yaml-based schema definition language. It can be used to generate other schema formats, such as JSON Schema, JSON-LD, xml, etc. By using LinkML for the canonical OSC-EM schema we can then automatically generate schemas in other languages, as well as convert data between some different data container formats. LinkML has broad community support.

Steps

• [ ] Convert OSC-EM schema to linkml format. The JSON Schema can be converted automatically using a schemauto importer
• [ ] Set up CI/CD to create JSON Schema and JSON-LD automatically. The actions are provided automatically if we apply the linkml cookiecutter to this repository.

Definition of done

• Instrument and Sample schemas are in LinkML
• JSON Schema is generated automatically for each commit to master

I created a project using the cookiecutter template. I will test using schemasheets, which allows you to use a tsv file for the canonical schema and generate linkml from that.
