topic.manufacturing-systems — retired
This identifier was retired on . The address keeps answering because it was published and a citation to it should not break.
What it was
An identifier minted from the value manufacturing systems in the
topics field of 1 of 132
tracked entries, on the day it was retired.
Whose vocabulary
This record’s own. topics held values typed per entry and
carried no publisher statement and no citation: no publisher was quoted
saying that any document was about manufacturing systems. That is
what distinguishes it from subject_as_stated, where each value
carries the publisher’s own words and the address they were read at.
Why it was retired
The topics field is now derived from each entry’s own
subject_as_stated by rule, and a topic identifier is now
a record identifier for a publisher-stated value. No entry states manufacturing systems,
so nothing mints this identifier any more. It is retired rather than deleted, and the
correction naming the span it was published for is on corrections.
Where the publisher-stated subjects are
The subject facet on the front page is built from
subject_as_stated, and each of its values carries the
publisher’s quote and the URL it was read at. The account of topic
identifiers is at conventions.
There is no publisher-stated equivalent of this identifier: that is the
reason it was retired, and offering a nearest match would be this record
authoring the association a second time.
