 Documenting your data with a schema makes it more FAIR.
 
-Formalized, machine-readable schemas are very useful and can be expressed in a number of languages including LinkML, Overlays Capture Architecture (OCA), JSON Schema, XML Schema Definition, and JSON-LD. Different schema languages have different benefits but the biggest advantage of using any schema language to document a schema is that the schema is documented and in a machine-readable format.

Different schema languages have different benefits but the biggest advantage of using any schema language to document a schema is that the schema is documented and in a machine-readable format.  Schemas also facilitiate application interface (API) development and exposes the structural information that enables users to query datasets directly.
 
-With a machine-readable schema you can use it for many other tasks including data verification, data entry and data harmonization. For example, the [Semantic Engine](https://www.semanticengine.org) helps researchers write their own data schemas using the OCA schema language. The [Data Harmonizer](https://github.com/cidgoh/DataHarmonizer) uses custom LinkML schemas to let researchers edit and validate tabular data according to the LinkML schema.
