name	folio
description	Search and browse FOLIO, the open legal ontology with 18,000+ concepts covering areas of law, document types, legal entities, and more. Use when classifying legal concepts, finding document types, identifying areas of law, or mapping legal entity structures. Classification workflows available as slash commands: /folio:classify-document, /folio:identify-area-of-law, /folio:classify-entity.

FOLIO Legal Ontology Skill

When to Use

Use the FOLIO MCP tools when you need to:

• Classify legal concepts: Find the correct ontology term for a legal concept
• Identify document types: Look up legal document classifications (contracts, filings, opinions)
• Find areas of law: Determine which legal practice area applies
• Map entity types: Identify types of legal entities (corporations, trusts, partnerships)
• Explore relationships: Find how legal concepts relate to each other
• Export definitions: Get formal definitions in markdown, JSON-LD, or OWL XML

How to Search

Follow this workflow:

1. Search by name: Start with folio:search_concepts(query) to find concepts by label
2. Refine by definition: If name search is too broad, use folio:search_definitions(query)
3. Advanced query: Use folio:query_concepts(label, definition, branch, parent) for composable filters
4. Query properties: Use folio:query_properties(label, definition, domain, range) to find relationships
5. Browse branches: Use folio:list_branches() then folio:get_taxonomy_branch(branch_name) to explore a category
6. Navigate hierarchy: Use folio:get_children(iri) and folio:get_parents(iri) to explore up/down the taxonomy

Classification Workflows

Three specialized classification workflows are available as slash commands. Suggest these to users when they need structured FOLIO classification:

Slash Command	Use When	Key Branches
/folio:classify-document	Classifying a legal document type	document_artifacts
/folio:identify-area-of-law	Identifying areas of law for a situation	areas_of_law
/folio:classify-entity	Classifying a legal entity, role, or org	actors_players, legal_entities

Each workflow searches, browses the relevant taxonomy branch, navigates to the best match, and returns: FOLIO Label, IRI, Definition, Confidence, and Reasoning.

Example Workflow

Task: Find the FOLIO classification for a "software licensing agreement"

1. folio:search_concepts("software licensing agreement")
   -> Finds candidates like "Software License Agreement", "License Agreement"

2. folio:get_concept(iri)
   -> Gets full details including definition, parent/child concepts

3. folio:get_parents(iri)
   -> Shows taxonomy: Software License Agreement -> License Agreement -> Contract -> Document/Artifact

4. folio:export_concept(iri, format="markdown")
   -> Gets a clean markdown export for documentation
