Tools 27 found in our last check

• resolve

  Resolve a Luxembourg legal-act identifier or a hash-pinned permalink to the work and expression it names.

• as_of

  The state of a Luxembourg act applicable on a date (publisher), with its articles; for an EU act, the wording dated at or before the date (an EU wording date, never an applicability date).

• timeline

  Every state of a Luxembourg act the index holds, in publisher applicability order; for an EU act, every wording its census discovered, in wording-date order.

• article_history

  The history of one article of a Luxembourg act across its states.

• diff

  The article-level difference between the states of a Luxembourg act on two dates.

• changes_in_period

  The Luxembourg states that began in a period, for a work or across the index.

• in_force_on

  The Luxembourg works with a state applicable on a date.

• search

  With no work named, first read the query as an exact reference (an ELI, a CELEX, an EU act's name, a Memorial citation, a historical identifier, a permalink, or a citation of an article of an act at a date) and answer the address its act opens at, the acts it may name, or a type…

• coverage

  What this mount holds and serves, named, and what it does not.

• provenance

  The retained sources, rule profiles and digests behind a Luxembourg state.

• dossier

  The work record of a Luxembourg act as the index holds it; for an EU work named by identifier, its held expressions from the EU index.

• citation

  The references the publisher wrote in the text of a Luxembourg state's articles.

• cited_by

  The references, in any held Luxembourg state, whose target is exactly this work.

• verify

  Verify a hash-pinned permalink against the state digest the index holds, or read the current digests to pin.

• relations

  The reference edges of a Luxembourg work in both directions, as one ordered, paged list.

• evidence_bundle

  What a quote of a Luxembourg state needs, one bounded page at a time (at most 50 articles and 96 KiB of text; page or article chooses the page, contents adds the table of contents): each article's text with its digests, the state's permalink, digests, sources and official identi…

• classification

  The publisher's typed facts about a Luxembourg work, verbatim: document type, RDF types, legal value, responsible body, historical identifiers, publication and document dates.

• manifestation

  The publisher's manifestations of a Luxembourg work's expressions with their formats and items, the retained one marked with its body digest.

• status_on

  The publisher's force assertions about a Luxembourg work (its inForceStatus, dateEntryInForce and dateNoLongerInForce facts), verbatim, beside the state applicable on a date, with one fixed reading of the dates.

• browse

  The Luxembourg works this mount holds, one ordered and paged list with their identifiers, languages, state dates and the publisher's document types; filter by type or language.

• ask

  The assistant, switched on as a labelled preview: the question, with obvious identifiers masked by code, is sent to the configured processor, which only plans which operations to run; code runs them, decides the verdict and writes every sentence from fixed wording; the answer is…

• events

  The Luxembourg event log, polled by cursor, at least once: a genesis log holds one first_sighting per held state; a chained log adds each later build's comparison events; each build's time, never an observation time.

• answer_drift

  The past dated answers a publisher revision invalidated, enumerated from the log's revising events; a genesis log holds none, and the answer says why rather than asserting that nothing drifted.

• as_observed

  The state of a Luxembourg act applicable on a date (publisher) as one build of the mounted log held it, named by that build's index digest, with its build time as an upper bound on observation; a time refuses, since no observation time is held.

• concepts

  Not served: the EuroVoc descriptors, directory codes and subject matters of EU works, which no index holds; every call answers the typed refusal retrieval_mode_unavailable, naming the modes this server serves and the data that would serve it.

• knowable_on

  Not served: what a reader could have known on a date, from publication and observation times, which no build records; every call answers the typed refusal retrieval_mode_unavailable, naming the modes this server serves (as_of, as_observed) and the data that would serve it.

• transposition

  Not served: the transposition links between EU directives and Luxembourg measures, which are not acquired; every call answers the typed refusal retrieval_mode_unavailable, naming the modes this server serves (citation, cited_by, relations) and the data that would serve it.
