- cc-by — this record, on the file portal’s resource
- CC-BY — jinji_20211001_0008, uppercase and hyphenated

One portal, four keys for Creative Commons Attribution. the file portal’s own licence
facet counts CC BY at 14,669 datasets and CC-BY at 679 as if they were
different licences. StackData folds case and punctuation and keeps a version
number only where the portal states one.
- gjstu — the file portal’s vocabulary key
- Government Standard Terms of Use 2.0 — the display label, stored in the id field — not a vocabulary key
- Government Standard Terms of Use 2.0 — the statistics portal’s site terms, written without the spaces
Normalized to
Government Standard Terms of Use 2.0
Government Standard Terms of Use 2.0 is not a vocabulary key at
all — it is the human-readable label pasted into the machine field, spaces and all. One the file portal dataset,
mlit_20140919_0726, carries both spellings across its own resources.
- "" — the file portal’s frequency field on this record is an empty string — flagged: no value published
- “Conducted every five years” — the statistics portal, written as a sentence
Normalized to
Every 5 years
the file portal’s frequency field is free text with no code list behind it. Across the
portal it holds, in translation, “1 year”, the same string with a different
digit character, “1 month”, “5 years”, “10 minutes”, “irregular”,
“not updated” and “at least once a year”.
- Population and Households — the file portal’s category, a label with no code
- code 02 · Population and Households — the other source, code and label together
Normalized to
02 · POP · Population and Households
The 17 category labels match string for string across sources, so this join needs
no crosswalk. the statistics portal carries the code, the file portal only the label, and StackData adds
the slug for URLs. One trap: the statistics portal codes Other as 99
while listing it seventeenth, so a join on position breaks on the last row.
- soumu_20220803_0013 — the file portal’s package id
- 00200521 — the statistics portal’s statistic code
Normalized to
POP · 00200521
the file portal mints its own id and publishes no the statistics portal code as a field. The only link is
inside the resource URL, and this record's one the file portal resource is hosted on
the statistics portal — as are resources in 4,533 of the file portal’s 18,144 datasets. Across
those, the the statistics portal key appears under twelve parameter names: statInfId, sinfid,
stat_infid, fileId, toukei, tstat, listID, lid, tclassID, bid, tid and tstatCode.
