title: DataLad Concepts
description: 'For many use cases metadata concepts are complex. Producing and consuming
such metadata involves sophisticated tooling, which implies a considerable technical
threshold for adopting metadata-focused workflows.
The schemas in DataLad Concepts aim to lower this threshold with an approach to
expressing rich and semantically precise metadata in relatively simple data structures
-- data structures that can be reasonably read from files and processed in scripts
with loops and conditionals, rather than requiring databases and specific query
languages implemented in targeted libraries.
All schemas are implemented in LinkML, connecting to a rich ecosystem for data modeling,
validation, and transformation. LinkML bridges between the worlds of structured
data in plain text files, relational databases and knowledge graphs if and when
needed, so metadata workflows can stay as simple as possible.
