Mapping a company onto an ontology
Mapping method: inventory every noun the business uses publicly, name the relationships between them as sentences, pick the most specific schema.org type for each, and write the decisions down.
The mapping method
Step 1: inventory the nouns. Org chart, service catalog, product list, office list, key people. One row per noun, no filtering yet.
Step 2: name the relationships. For each pair of nouns, write the sentence that connects them. "The company offers the service." "The person works for the company." If you can't say it, it's not a relationship - it's an assumption.
Step 3: pick types. The most specific schema.org type you can defend. LocalBusiness beats Organization when there's a real address customers visit.
Step 4: record decisions. Why this type, why this @id, why this relationship exists. The map outlives the mapper.
The output is a table, not a diagram: entity, type, relationships, facts. Everything else - schema graphs, feeds, content architecture - is generated from that table.
