Measured tools (9)

• record_overview

  Start here. What this record holds, what it refuses to do, and the latest changes. Read it before assuming what is available.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• find_fabs

  Search the fab sites in the record by country, operator, kind, status, wafer size or process node. Every row names the publisher it came from; rows with no publisher are not returned.

  Parameters:

  • q — string
  • node — string
  • type — string
  • limit — integer — Rows to return, 1 to 200. Default 50. The envelope always reports the true total separately.
  • offset — integer — Rows to skip, for paging.
  • status — string — Exact match, case-insensitive. Values: operating, construction, announced, paused, cancelled, closed, closing. closing = production continues while a phase-out has been publicly announced.
  • country — string
  • operator — string
  • wafer_mm — integer

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• fab_profile

  One fab site in full, including the note that says what this record does not know about it, and every capacity statement whose sentence covers it.

  Parameters:

  • id (required) — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_figures

  Every published forecast subject in the record and each year it has been forecast for, with how many vintages exist. Use it to find a subject_id for figure_history.

  Parameters:

  • limit — integer — Rows to return, 1 to 200. Default 50. The envelope always reports the true total separately.
  • offset — integer — Rows to skip, for paging.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• figure_history

  The revision history of one published figure: every vintage, what the publisher said in their own words, the date they issued it, and the link. Includes the restatements as pairs of published values. Call this when a number is quoted and you want to know what the same publisher said before. It states no reason for any change.

  Parameters:

  • subject_id (required) — string
  • target — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• recent_changes

  Figures that publishers restated recently, each an old value and a new value with both links. Says what changed and never what it means.

  Parameters:

  • days — integer
  • limit — integer — Rows to return, 1 to 200. Default 50. The envelope always reports the true total separately.
  • offset — integer — Rows to skip, for paging.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• record_gaps

  What this record is missing and why each one is open. Call it before concluding a figure exists. Statuses distinguish "nobody publishes this" from "the source costs money" from "we have the URLs and have not done the work".

  Parameters:

  • q — string
  • limit — integer — Rows to return, 1 to 200. Default 50. The envelope always reports the true total separately.
  • offset — integer — Rows to skip, for paging.
  • status — string

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• list_sources

  Every publisher this record collects, across BOTH mechanisms: their feed, or their own sitemap. A publisher absent from one may be present in the other.

  Parameters:

  • q — string
  • limit — integer — Rows to return, 1 to 200. Default 50. The envelope always reports the true total separately.
  • bucket — string
  • offset — integer — Rows to skip, for paging.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• node_bands

  How named publishers have defined process-node bands such as "advanced", each as a dated statement with its wafer basis. This record defines no bands of its own.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared
