Measured tools (22)

• export_bibliography read-only

  Generate standard UTF-8 BibTeX and a direct .bib download URL for all matching works/editions/translations. Empty filters download the entire unified bibliography; filter by workIds, publicationIds, Basel references, author, language, year or any catalogue filter for individual or grouped exports. Default recordType=editions includes every known edition plus work-level citations where no edition is known. Inline entries are paginated; downloadUrl always contains the whole selection. Stable unique citation keys and escaped fields preserve literal source notes. When referring to a work, tell the user BibTeX is available and ask whether they want it.

  Parameters:

  • offset — integer
  • filters — object
  • pageSize — integer
  • recordType — string
  • includeInline — boolean

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_bibliography_source read-only

  Read the supplied Basel bibliography's original PDF pages, including all edition/translation changes, cross-references, contextual notes and unnumbered supplements. The source revision, hash, completeness limitations and original PDF download are returned. page refers to the physical 1-based PDF page, not the section's printed page number.

  Parameters:

  • page — integer
  • pageSize — integer

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• list_works read-only

  List public works with combinable filters, exact counts and optional facets. Includes works without digital publications. Default year is original publication year.

  Parameters:

  • page — integer
  • facets — boolean
  • offset — integer
  • sortBy — string
  • filters — object
  • pageSize — integer
  • sortOrder — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_work read-only

  Get the complete bibliographic work record and all its public publications. Author/type scope applies to IDs too.

  Parameters:

  • workId (required) — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• list_publications read-only

  List publication summaries. workTypes filters contained works; publicationTypes filters derived publication classification. Filters on author/type/original year match the same contained work.

  Parameters:

  • page — integer
  • facets — boolean
  • offset — integer
  • sortBy — string
  • filters — object
  • pageSize — integer
  • sortOrder — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_publications read-only

  Get detailed publication records by filters.publicationIds or any combination of listing filters, including workTypes and publicationTypes. Paginated; full texts use get_publication_text.

  Parameters:

  • page — integer
  • facets — boolean
  • offset — integer
  • sortBy — string
  • filters — object
  • pageSize — integer
  • sortOrder — string

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_publication_text read-only

  Read the downloadable EPUB/PDF text in ordered sections. Continue using nextOffset until null. Includes source URL, format and locators. Does not assume publication.text is complete. A collective source is the publication text, not necessarily one contained work.

  Parameters:

  • publicationId (required) — string
  • limit — integer
  • offset — integer

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• search_publication_text read-only

  Find literal phrases, ignoring case and accents, in a public publication's extracted EPUB/PDF text. Returns bounded exact context with locators and nextOffset; no embeddings or generated summaries. A collective publication may contain several authors.

  Parameters:

  • publicationId (required) — string
  • query (required) — string
  • limit — integer
  • offset — integer

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_download_links read-only

  Get existing download links, optionally checking availability. Resolves verified source corrections. Does not generate files.

  Parameters:

  • publicationId (required) — string
  • checkAvailability — boolean

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_catalog_options read-only

  Get recognized and enabled types, authors, language codes and public subject labels. Corpus expansion is configuration controlled.

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_corpus_coverage read-only

  Get coverage and exclusions by author and original language under bibliography filters. Use before comparisons; unavailable text is not evidence of absence.

  Parameters:

  • filters — object

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• search_works read-only

  Search public catalog metadata and complete or selected passages with multilingual embeddings. Queries may be in any language. Evidence is grouped by bibliographic work and identifies one selected analysis language, original/translation status, source and coverage. Optional lexicalQueries provide BM25 terms in the selected analysis language. Catalog descriptions are not author quotations; partial book selection cannot establish thematic absence. Listing tools provide exhaustive bibliographies.

  Parameters:

  • query (required) — string
  • limit — integer
  • filters — object
  • lexicalQueries — array

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

  Parameters:

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_person_life_and_mission read-only

  Return exact Spanish biographical and mission passages for Hans Urs von Balthasar or Adrienne von Speyr. The mission topic also includes explicitly identified common-mission evidence. The service does not summarize or infer.

  Parameters:

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_community_of_saint_john read-only

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• search_life_mission_and_community read-only

  Search exact Spanish passages about Balthasar, Speyr, their common mission and the Community of Saint John. Matching is lexical and accent-insensitive; results are source evidence, not generated answers.

  Parameters:

  • question (required) — string
  • offset — integer
  • topics — array
  • pageSize — integer
  • subjects — array

  Hints: read-only yes · destructive no · idempotent yes · open-world no

  • periodYears — integer

  Hints: read-only yes · destructive no · idempotent yes · open-world no

  Hints: read-only yes · destructive no · idempotent yes · open-world no

• get_topics_by_period read-only

  Compare precomputed thematic indicators by period. Editorial and lexical assignments are default; filters.includeSemantic explicitly includes embedding associations. firstYears requires exactly one author and starts at their earliest catalogued work.
