Ontology and semantic-resource landscape

A growing landscape inventory of 86 resources, not an exhaustive list or an adoption decision. Formal and application ontologies, standards, classifications, thesauri, frameworks and historical efforts serve different purposes.

The canonical CSV lives in data/semantics/semantic_resources.csv. This page and the coverage matrix are generated with python scripts/generate_semantics.py. Download every inventory field, auditable project assessments or inspected registry fact evidence.

Resource identities, registry status and cited documentation are resource facts with a verification scope. Coverage, candidate roles, eras, limitations and influence are provisional project assessments by the coding assistant, not expert-reviewed ontology properties. Unknown release dates/rights stay unknown. A milestone below is not necessarily the first release; eras overlap.

Do not collapse distinctions

Organism, taxon, population and community describe different things. An ontology, vocabulary and exchange standard are also different kinds of resource. Scale is not one dimension.

Resource details, limitations and evidence

An empty crosswalk/dependency field means not recorded in this review, not that none exists. Registry dependency metadata is not a parsed OWL-import graph. Resolvable identifiers mean the source declares persistent identifiers; live resolution of every term was not tested. Portal APIs are not assumed from a downloadable OWL file.
