記録の来歴

Provenance is the account of where a record came from: who issued it, when, by what method, from which sources and through which transformations it passed before reaching the reader. Without it a record cannot be checked, weighed or corrected, only trusted or ignored. This page sets out how provenance is captured and expressed, why lineage chains break, and what the people who rely on registry records need to see before they do.

02質問

Record provenance: how the risk develops.

Issuer, date, method and source lineage. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.

メカニズム

Lineage breaks at hand-offs

Records pass between spreadsheets, databases, aggregators and exports. Each step can drop the issuer, the source reference or the method note. Once the chain is cut, later copies look authoritative while nothing connects them to what they were derived from.

メカニズム

Issuer ambiguity

Organisation names change, merge and are spelt many ways, and people share names. Without persistent identifiers for issuers, two bodies are recorded as one or one as two, and responsibility for an assertion can no longer be established.

メカニズム

Method drift

The method behind a field changes, through a new coding rule, a new instrument or a revised definition, while the field name stays the same. A series then joins incompatible values, and no reader can see where the join is.

メカニズム

Laundering through aggregation

An unsourced claim is copied by an aggregator, quoted in a report and indexed by search engines. Each reuse adds apparent authority and removes context, until the claim is cited back to its origin as if it were independent confirmation.

08中核となる問い

What provenance research asks.

  • What is the smallest set of facts that lets a reader judge a record’s origin?
  • How much lineage should be captured automatically, and how much asserted by people?
  • How can provenance survive when records are copied, transformed or merged?
  • How do we record a source that cannot be disclosed?
  • How can a lineage claim itself be verified rather than trusted?
09メカニズム

How lineage is lost.

Lineage is usually lost at boundaries: when a dataset is exported to a spreadsheet, when a figure is retyped into a report, when two sources are merged without recording which value came from where. Each step can be innocent, yet together they produce numbers whose origin no one can reconstruct. Archival science calls the related principle respect for provenance: records keep their link to the body that created them and to their original order.

Modern provenance models describe three kinds of thing: entities such as datasets and reports, activities such as a model run or a review, and agents such as people, institutions and software. The W3C PROV family of specifications expresses these relationships in a form machines can read, and the Registry’s lineage design is intended to follow it, as described on provenance and attribution.

10手法と限界

Capturing and checking lineage.

  1. 01

    Issuer and authority

    Each record names who issued it and under what authority, so a reader knows whose word it is.

  2. 02

    Activity records

    Transformations, model runs and reviews are recorded with their method version and date.

  3. 03

    Integrity checks

    Cryptographic hashes can show that a file has not changed since it was recorded, a technique from サイバーセキュリティと暗号.

  4. 04

    限界

    Provenance shows where a record came from, not whether its content is right. Lineage is only as complete as the steps that were captured, and self-declared provenance can be false. Restricted sources can be named but not inspected.

13質問

質問と回答。

What is the difference between provenance and a source?
A source is one input. Provenance is the whole account: every input, the activities that transformed them, the agents responsible and the time at which each step happened.
What happens to records with incomplete provenance?
They are published with the gap stated, or held for curation, under the steward’s rules. Missing elements are shown as missing, never filled with a guess presented as fact.
Does a digital signature make a record true?
No. A signature binds content to a signer and shows whether it changed afterwards. Whether the content is correct depends on the method and sources behind it.
Why do issuers need persistent identifiers?
Because names are ambiguous and change over time. An identifier such as a ROR ID or ORCID iD keeps responsibility attached to the right organisation or person through mergers, renamings and moves.
Is provenance the same as citation?
No. A citation points to a source. Provenance records the full chain of production, including the methods and the people or systems involved.
What happens when a source is corrected?
Records that depend on it are identified through their lineage and reviewed. See correction and versioning.
Can provenance include restricted sources?
Yes. The record states that a restricted source was used, who holds it and why it cannot be shown, without revealing its content.
