Schemasheets is a framework for managing your schema using spreadsheets (Google Sheets, Excel). It works by compiling down to LinkML, which can itself be compiled to a variety of formalisms, or used for different purposes like data validation

Documentation

See the Schema Sheets Manual

Quick Start

pip install schemasheets

You should then be able to run the following commands:

• sheets2linkml - Convert schemasheets to a LinkML schema
• linkml2sheets - Convert a LinkML schema to schemasheets
• sheets2project - Generate an entire set of schema files (JSON-Schema, SHACL, SQL, ...) from Schemasheets

As an example, take a look at the different tabs in the google sheet with ID 1wVoaiFg47aT9YWNeRfTZ8tYHN8s8PAuDx5i2HUcDpvQ

The personinfo tab contains the bulk of the metadata elements:

record	field	key	multiplicity	range	desc	schema.org
> class	slot	identifier	cardinality	range	description	exact_mappings: {curie_prefix: sdo}
>
	id	yes	1	string	any identifier	identifier
	description	no	0..1	string	a textual description	description
Person		n/a	n/a	n/a	a person,living or dead	Person
Person	id	yes	1	string	identifier for a person	identifier
Person, Organization	name	no	1	string	full name	name
Person	age	no	0..1	decimal	age in years
Person	gender	no	0..1	decimal	age in years
Person	has medical history	no	0..*	MedicalEvent	medical history
Event					grouping class for events
MedicalEvent		n/a	n/a	n/a	a medical encounter
ForProfit
NonProfit

This demonstrator schema contains both record types (e.g Person, MedicalEvent) as well as fields (e.g. id, age, gender)

You can convert this like this:

sheets2linkml --gsheet-id 1wVoaiFg47aT9YWNeRfTZ8tYHN8s8PAuDx5i2HUcDpvQ personinfo types prefixes -o personinfo.yaml

This will generate a LinkML YAML file personinfo.yaml from 3 of the tabs in the google sheet

You can also work directly with TSVs:

wget https://raw.githubusercontent.com/linkml/schemasheets/main/tests/input/personinfo.tsv 
sheets2linkml personinfo.tsv  -o personinfo.yaml

We recommend using COGS to synchronize your google sheets with local files using a git-like mechanism
