Any time an ontology identifier is about to be written down or trusted: annotating a metadata column, filling a submission template, auditing a table someone else produced, or checking whether an ID in an old file is still current.
Never write an ontology ID from memory, and never accept one without checking it.
Ontology IDs are memorable in form and arbitrary in detail. A plausible-looking UBERON:0002108
is a real term (small intestine) that is not the liver, and nothing downstream will catch the
substitution — the ID is well-formed, the ontology is right, and the metadata is silently wrong.
Reviewers cannot spot it either, which is why these errors persist into published datasets.
OLS search and ZOOMA emit candidates. Validate each selected ID with OLS term detail, then check its definition against the sample and the target schema before accepting it. Bioregistry, Identifiers.org, ZOOMA, and Ontobee answer prefix, landing-page, and shorthand questions — they do not replace that OLS check.
| Question | Script | Authority |
|---|---|---|
| What is the term for "left ventricle"? | scripts/resolve_terms.py | OLS |
OLS missed lab shorthand (PBMC, WT) | scripts/map_terms.py, then validate_terms.py | ZOOMA proposes; OLS validates the term |
Is EFO:0001067 real, current, correctly labelled? | scripts/validate_terms.py | OLS |
Is HPO a real prefix? Does HP:notanid match the pattern? | scripts/lookup_prefix.py | Bioregistry |
| Which landing page should this CURIE open? | scripts/lookup_prefix.py | Identifiers.org + Ontobee URLs |
All four scripts take single values or files, emit TSV or JSON, and need no packages beyond the
standard library. Full traps for the non-OLS services are in references/companion-apis.md.

--exact-only --format tsv -o resolved.tsv
# accept fuzzy fallbacks, then review the partial hits by hand
python3 resolve_terms.py "left ventrical of heart" --ontology uberon --top 3
The search escalates exact (label and synonym) → token → fulltext and stops at the first
strategy that returns candidates, reporting which one fired. --exact-only disables the ladder
and locally rejects partial, related, broad, narrow, and unscoped synonym matches. Searches
are bounded candidate lists (--top), not exhaustive ambiguity checks.
--branch UBERON:0000465 uses OLS hierarchical ancestry, including part-of/develops-from.
Read match_type before using a result. exact_label and exact_synonym establish lexical
agreement (the latter also requires an exact synonym annotation), not correct sample context.
related_synonym, broad_synonym, narrow_synonym, unspecified_synonym, and partial require
curation. Validate every selected ID; search does not expose obsolescence in its records.
unresolved is a legitimate output. See references/curation-rules.md before normalising input.

Exit code is 1 if anything failed, 0 otherwise, 2 on usage or network trouble — so it works as a CI gate on a metadata file:
# id + label columns; catches IDs that exist but are labelled as something else

python3 validate_terms.py --input tissue_ids.tsv \

| Status | Meaning | Verdict |
|---|---|---|
ok | Exists, current, consistent with everything asserted | pass |
matched_synonym | Claimed label is a synonym; primary label differs | warn |
imported_only | No defining copy was verified in OLS | warn |
not_a_class | Term is a property or individual | warn |
not_found | No such term | fail |
obsolete | Obsoleted; replacement gives the successor when one exists | fail |
label_mismatch | Claimed label matches neither primary label nor recorded synonyms | fail |
wrong_ontology | Right kind of ID, wrong ontology for this column | fail |
wrong_branch | Not a descendant of the required root | fail |
malformed_curie | Not of the form PREFIX:local | fail |
--strict promotes warnings to failures. --expect-ontology checks the identifier namespace,
so a CL term imported into UBERON cannot pass a UBERON-only column. OLS ontology ids and
Bioregistry preferred prefixes are not interchangeable (ORPHA/Orphanet uses OLS ordo).
Use --branch-relation is-a for subclass-only validation; the default hierarchical also
includes part-of/develops-from. A missing/obsolete branch root is a usage error, not a negative
scientific result. not_found means absent from this OLS lookup, not proof of global nonexistence.

Bioregistry accepts synonym prefixes. Identifiers.org does not — HPO:0001250 is HTTP 400.
Use the preferred prefix for Bioregistry, then verify the OLS namespace/IRI. The bundled
validator handles both ORPHA:558 and OLS’s Orphanet:558; this is not a universal alias rule. Landing-page columns come from
Bioregistry mappings (providers.miriam, mappings.ontobee), not from templating that
preferred prefix: ORPHA:558 is a 400, orphanet:558 is a 200, and OBA has no Identifiers.org
namespace at all. Empty cells mean the service does not host the prefix. This script does
not say the term exists; that is still validate_terms.py.
# after resolve_terms.py returned unresolved / partial
python3 map_terms.py PBMC --ontology cl --high-confidence-only
--ontology is required by this client; it requests defining terms in the selected ontologies.
The public v2 compatibility endpoint remains supported, while current ZOOMA docs also expose v3.
HIGH/GOOD are ranking buckets, not calibrated probabilities or exact matches. The legacy safe
column and zooma_safe label mean only HIGH/GOOD; --exact-only remains an alias for the
confidence filter. evidence/source come from underlying derivedFrom provenance, because
the outer wrapper can say ZOOMA_INFERRED_FROM_CURATED even for embedding matches.
Run validate_terms.py and review the meaning before accepting a candidate.

| Trap | Consequence |
|---|---|
exact=true is exact token matching | liver returns 161 hits in UBERON; adding queryFields=label returns 1 |
/search never returns is_obsolete or term_replaced_by | Named in fieldList they are dropped silently; only term detail can answer "is this ID still current" |
ontology=efo returns MONDO and CL hits | Ontologies import each other; filter on the CURIE prefix yourself |
| The same term appears once per importing ontology | Deduplicate on obo_id, keep is_defining_ontology: true |
An obo_id query can miss a term | IRI fallback remains necessary for Orphanet; the former MONDO index gap is now fixed |
obsoletes=true on the v1 search API | Currently selects obsolete-only results; the helper merges two queries when inclusion is requested |
synonym combines scopes | iecur is a related synonym of liver; it must not become an exact synonym match |
| IRIs are not all OBO PURLs | EFO and Orphanet use their own namespaces — resolve IRIs, do not template them |
| OxO has changed | OxO2 is live and supports compatibility routes; inspect mapping predicates and provenance, not just cross-reference reachability |
| A branch check does not exclude cell types from anatomy | CARO puts cell under anatomical structure; constrain the prefix too |
| ZOOMA confidence and provenance | HIGH can be lexical and GOOD can be a narrower organ part; confidence is not an acceptance decision |
| Identifiers.org synonym prefixes | HPO:0001250 is HTTP 400; Bioregistry accepted the same CURIE |
| Identifiers.org encoded colon | HP%3A0001250 is HTTP 400; the path must keep : |
Bioregistry preferred_prefix is not the Identifiers.org namespace | ORPHA:558 is 400; orphanet:558 is 200. hp:0001250 and chebi:15377 are 400 because those namespaces embed the prefix in the LUI. Use providers.miriam from /api/reference/{CURIE}; omit the URL when that mapping is missing (OBA, XAO, ECTO) |
| Ontobee search | HTML page only — no JSON API; do not scrape it |
MONDO for disease, HP for phenotype, UBERON for tissue, CL for cell type, EFO for assay, ChEBI for
compounds and NCBITaxon for organism. PATO sex/normal terms are appropriate only when the
target schema permits them and the source data establish the relevant state; missing disease
or a control-group label does not establish health. Prefix-to-OLS-id mappings (HP
is served as hp, Orphanet as ordo), branch roots for --branch, and the overlapping-ontology
judgement calls are in references/ontology-registry.md.
Give the ID and the label, and say how each was matched. A table of bare IDs cannot be reviewed. State unresolved terms explicitly rather than filling them with the nearest hit.
Record the lookup date, ontology identifier, and ontology version IRI or release metadata
when available, alongside the original input and selected term IRI. OLS serves changing
ontology releases, so a live validation is evidence for that lookup date; preserve the
response or exported mapping when an analysis must be reproduced. Fetch GET https://www.ebi.ac.uk/ols4/api/ontologies/{ontology} for config.versionIri,
config.version, and loaded/updated; these may be null. A live OLS check does not validate
against an archive’s pinned ontology release. Use that release and its validator for submission.
