Available tools
- Authority Identifier Check Digit Source Row Tool Record an explicit authority identifier check-digit transcription and algorithm source without inventing or applying a registry algorithm.
- Bibliographic Date Uncertainty Qualifier Tool Preserve explicit bibliographic date transcription and uncertainty qualifier without constructing missing date fields.
- Collection Provenance Agent Role Token Tool Preserve an explicit collection provenance agent-role assertion without verifying ownership or chain of custody.
- Controlled Vocabulary One Deprecation Date Tool Caller-defined deprecation-date boundary for a supplied vocabulary record, without an external vocabulary lookup.
- Document Access Tier Order Tool Compare supplied access-tier tokens under an explicit ordering without granting access or establishing authorization.
- Document Dublin Core Date Label Label supplied descriptive date text and role without validating a Dublin Core encoding scheme.
- Document Relation Self Loop Flag Tool Inspect exact supplied document identities on one directed relation edge.
- Identifier Namespace Version Token Tool Split a caller-defined namespace/local/version grammar without canonicalizing identifier schemes.
- Indexing Stopword Position Increment Tool Preserve original token positions across explicitly flagged stopwords; the initial token has one-based position increment from position -1.
- Information Retrieval Dcg One Rank Term Tool One DCG contribution with explicit linear versus exponential gain and one-based rank.
- Information Source Edition Tag Qualify explicit source-edition wording without normalizing publication history.
- Knowledge Record Validtime Assertion Pair Tool Preserve explicit knowledge-record assertion time and valid-time bounds without conflating transaction and valid time.
- Metadata Cardinality One Property Budget Tool Calculate metadata cardinality one property budget from explicit caller-supplied inputs.
- Metadata Controlled Value Source Key Qualify a literal controlled metadata value by its supplied vocabulary source without validating membership.
- Metadata Field Obligation Flag Tool Inspect supplied metadata-field presence and obligation flags without selecting a metadata standard.
- Metadata Language Script Pair Tool Preserve explicit metadata language and script tags without detecting text or consulting a code registry.
- Metadata Obligation Missing Count Tool Count explicit metadata obligations without inferring a cataloging standard.
- Metadata Relation Inverse Flag Tool Compare an explicit inverse-relation map without asserting semantic inverse properties from names.
- Metadata Repeatability Flag Check an explicit metadata occurrence count against supplied required and repeatable flags.
- Metadata Source Coverage Share Tool Calculate metadata source coverage share from explicit caller-supplied inputs.
- Ontology Edge Inverse Label Reverse one ontology edge using an explicitly supplied inverse predicate without inferring ontology semantics.
- Ontology Label Language Fallback Choice Tool Choose an exact preferred language label or explicit fallback from aligned unique language tags without prefix matching or translation.
- Persistent Identifier Resolver Prefix Token Tool Append one percent-encoded opaque identifier to an explicit HTTP(S) resolver prefix; embedded identifier slashes are encoded, and no resolver service is selected.
- Persistent Identifier Scheme Case Rule Tool Apply an explicitly supplied Unicode-default lowercase comparison policy to identifier text without assuming scheme-specific case rules.
- Query Phrase Missing Token Position Flag Tool Locate missing supplied phrase tokens by original position, preserving duplicates and exact case.
- Query Phrase Slop One Gap Tool One ordered-position gap displacement against an explicit phrase policy, not a complete search-engine phrase-slop implementation.
- Query Stopword Policy Flag Apply an explicit exact-token stopword policy without language detection, case folding, or tokenization.
- RDF Blank Node Local Scope Guard Tool Compare explicitly scoped blank-node labels; the accepted label grammar is a documented ASCII subset rather than the complete RDF grammar.
- RDF Data Type Language Conflict Tool Detect a supplied language-tag/datatype conflict without validating literal lexical space or fetching vocabularies.
- RDF Datatype Lexical Boundary Check Tool Lexical-shape check for selected XML Schema integer, decimal and boolean primitives; preserves lexical spelling and does not apply a whitespace facet.
- RDF Language Tag Literal Pair Tool Language-tagged RDF literal identity preserves lexical text and ASCII-case-normalizes a syntactically shaped language tag; no IANA registry validation.
- Retrieval Query Document Pair Label Construct an unambiguous ordered retrieval query-document identifier pair.
- Search Result Reciprocal Rank Term Tool One first-relevant-result reciprocal-rank contribution; caller must identify the first relevant result and total query denominator.
- Search Result Relevance Grade Token Record a supplied query-document relevance judgment without computing relevance or enforcing a grading scale.
- Search Snippet Highlight Offset Pair Tool Split a supplied search snippet at explicit half-open Unicode code-point offsets, returning plain text segments without markup.
- SKOS Notation Datatype Literal Pair Tool Lossless SKOS notation lexical-form/datatype tuple; notation is not coerced to a number.
- SKOS Preferred Label Language Budget Tool Count distinct supplied preferred-label literals per case-insensitive language tag, collapsing duplicate RDF literal rows.
- Taxonomy Parent Path Segment Split an explicit nonempty taxonomy path into parent path and terminal segment without resolving a taxonomy.
- Thesaurus Preferred Alt Label Conflict Tool Audit SKOS preferred/alternative label disjointness using lexical text plus case-insensitive language tags, and distinct preferred labels per language. Identical repeated preferred literals are deduplicated; no language registry lookup or concept equivalence is inferred.
- Vocabulary Concept Branch Depth Tool Inspect a supplied vocabulary parent graph, preserving polyhierarchy and explicitly flagging cycles.
- Vocabulary Polyhierarchy Parent Count Tool Count distinct explicitly listed direct parents without inferring transitive ancestry.
