ISOBOX reuse taskforce — Helptext

What is this? (this text box: v e ): Per December 2022, a WP:ELEMENTS taskforce is working to re-use isotopes data. Isotopes present in Isobox <element> are reused in Infobox <element> (read & shown, automatically and real-time).; This task is to check whether the reused data indeed has all abandoned data.; The lefthand table is the Isobox(Pm). This data is live, and is shown in both "Isotopes of promethium", and in Infobox (Pm) → "Promethium". File:Green check.svgY; The righthand (middle of page) table is the old "Main isotopes of element" data from Infobox (Pm), which does not show any more and will be deleted. File:Red x.svgN
Todo

A. Please compare & check the two tables and sources. Update the lefthand Isobox as needed.

When the situation is unclear or to be researched, leave a comment in |checknote1=.

When OK, add the following to this Infobox page (edit), inside the {{infobox ..}} template code:

{{Infobox uranium
|check     = ok
|checknote1= Not sure about xyz, someone pls take a look

B. Old Infobox parameters |isotopes comment=, |isobox ref= to remove.

Deprecated parameters (done)

Tracked in ref & cmt category (0), as blacklisted parameters.

1. Manually copy/paste from Infobox to Isobox:

|isotopes ref=→|isobox ref=

|isotopes comment=→|isotopes comment=

2.These parameters may then be deleted from the Infobox (and so disappear from the category).

For Z>=E119, there is new parameter |theoretical isotopes comment=.

The table rows ({{isotope .. / .. decay2|mn= ..}} &tc.) now have new |ref=, one per isotope.

File:Yes check.svg Done (Cf, F, Pb). For Z>=E119, there is new parameter |theoretical isotopes comment=.

C. Align the named references.

TL;DR: Named references must be checked for exact spelling (c/p). Red messages in article References section.

References can be named, defined and reused over four pages: Article, Isotopes of <element>, {{Infobox <element>}}, {{Infobox <element> isotopes}}. In the wikicode, they appear as <ref name="Hofmann2016">..</ref>, and reused as <ref name="Hofmann2016" />.

Those ref name (reused) and ref content (when redefined) must be exactly the same (true copy/paste).

Misspellings appear as red error messages in the references section of the two live articles.

Resolving: these messages are to be removed by checking and copy/pasting the <syntaxhighlight lang="text" class="" id="" style="" inline="1">ref name=</syntaxhighlight> wikicodes.

Sometimes it is easier to remove a reference (already abandoned) from the Infobox completely, after checking it is in the Isobox allright.

Examples demo: IB(U)/s · IB(119)/s · IB(121)/s

Notes

|checknote1=My comments is a mini-talk, free to use and expand, to communicate about this element.

|checknote2= same.

|check=ok will re-sort this Infobox <element> in the task category from <syntaxhighlight lang="text" class="" id="" style="" inline="1">*</syntaxhighlight> (not ok) to <syntaxhighlight lang="text" class="" id="" style="" inline="1">O</syntaxhighlight> (ok).

Text can be different: |check=todo: foobar, will read as "not ok yet".

Please do not remove the isotopes data from the Infobox, and do not edit the meta-templates.

OTOH, |isotopes ref=, |isotopes comment= and abandoned references may be deleted from Infobox <element> (see B, C).

Other data can be edited as usual.

Standard atomic weight data is not affected (to be ignored).

When all Infoboxes are OK and stable, this Isobox reuse task will be ended, data removed.
