# Describe a dataset Publish / describe emit metadata: data dictionary, schema file, lineage, data package descriptor Page: ## Status Not built yet. arcform does not do this yet. [Its place on the roadmap](https://meridian.online/roadmap#describe-a-dataset) arcform has `datapackage_describe` for a Frictionless Data Package descriptor. ## Variants - Describe a table or model in place: Attach comments, glossary terms, schema descriptions or metadata fields to a table, column or model. - [Document pipelines and their lineage](https://meridian.online/operations/describe-a-dataset/document-pipelines-and-their-lineage): Generate documentation of pipelines, or rows of lineage saying which tables and assets each pipeline reads and writes. - [Publish metadata to a data catalog](https://meridian.online/operations/describe-a-dataset/publish-metadata-to-a-data-catalog): Send harvested metadata about datasets and their fields to a data catalog service. ## What other tools call it Meridian's classification; an independent blind rating agreed on 86.2% of 312 rows (exact class, version 2). - Alteryx Designer: [`Connect JSON Builder`](https://help.alteryx.com/current/en/designer/tools/connect/connect-json-builder.html) (read 2026-09-27) - Alteryx Designer: [`Connect Output`](https://help.alteryx.com/current/en/designer/tools/connect/connect-output.html) (read 2026-09-27) - Alteryx Designer: [`ODBC Loader`](https://help.alteryx.com/current/en/designer/tools/connect/odbc-tool.html) (read 2026-09-27) - Bruin: [`Dashboard assets (family)`](https://getbruin.com/docs/bruin/assets/dashboard.html) (read 2026-09-27) - Bruin: [`Glossary`](https://getbruin.com/docs/bruin/getting-started/glossary.html) (read 2026-09-27) - Bruin: [`Source assets (family)`](https://getbruin.com/docs/bruin/platforms/bigquery.html) (read 2026-09-27) - Bruin: [`quicksight.dashboard`](https://getbruin.com/docs/bruin/assets/quicksight-refresh.html) (read 2026-09-27) - Bruin: [`tableau.dashboard`](https://getbruin.com/docs/bruin/assets/tableau-refresh.html) (read 2026-09-27) - Bruin: [`tableau.worksheet`](https://getbruin.com/docs/bruin/assets/tableau-refresh.html) (read 2026-09-27) - DuckDB: [`COMMENT ON`](https://duckdb.org/docs/current/sql/statements/comment_on) (read 2026-09-27) - EasyMorph: [`Catalog command`](https://help.easymorph.com/doku.php?id=transformations:catalogcommand) (read 2026-09-27) - Apache Hop: [`Build documentation`](https://hop.apache.org/manual/latest/workflow/actions/documentation.html) (read 2026-09-27) - Apache Hop: [`Database impact input`](https://hop.apache.org/manual/latest/pipeline/transforms/dbimpactinput.html) (read 2026-09-27) - OpenRefine: [`Export Wikidata schema`](https://openrefine.org/docs/manual/exporting#export-data) (read 2026-09-27) - Pentaho Data Integration: [`Automatic Documentation Output`](https://docs.pentaho.com/pdia-data-integration/9.3-data-integration/pdi-transformation-steps-reference-overview) (read 2026-09-27) - Pentaho Data Integration: [`Write metadata`](https://docs.pentaho.com/pdia-data-integration/9.3-data-integration/pdi-transformation-steps-reference-overview) (read 2026-09-27) - RapidMiner Studio: [`Scan Processes`](https://docs.rapidminer.com/latest/studio/operators/extensions/Operator%20Toolbox/utility/scan_processes.html) (read 2026-09-27) - Yggdrasil Decision Forests: [`ModelMetadata`](https://github.com/google/yggdrasil-decision-forests/blob/0a54b57c95ff0cf42ecf0310ace0513a4f32cb65/yggdrasil_decision_forests/port/python/ydf/model/model_metadata.py) (read 2026-09-27) - Yggdrasil Decision Forests: [`metadata / set_metadata`](https://github.com/google/yggdrasil-decision-forests/blob/0a54b57c95ff0cf42ecf0310ace0513a4f32cb65/yggdrasil_decision_forests/port/python/ydf/model/generic_model.py) (read 2026-09-27)
