resolver

Alternative resolver

Configuration in: Module:URIutil/urn

fragment

demo

1 – suppress any fading out of error messages, e.g. in manual context; also do not generate maintenance categories

Parameters of #invoke for project specific adaption; all optional:

errCat

Title of a maintenance category in case of invalid parameter value etc.

errClasses

Classes to be adjoined to error messages, like error (always provided)

errHide

1 – hide error messages by default

errNS

Space separated list of wiki namespace numbers which limit maintenance category.

Default: Throw errCat in all namespaces.

Returns: external link or error message, e.g. as class="error".

failsafe

Version ID (local): 2020年01月18日

Optional parameter:

• 1 – Minimum version or wikidata or ~

{{#invoke:Vorlage:URN|failsafe}} yields 2020年01月18日

With a parameter as ISO date it is compared whether the current module satisfies this version or later.

• {{#invoke:Vorlage:URN|failsafe|2001年01月01日}} returns: »2020年01月18日«
• {{#invoke:Vorlage:URN|failsafe|2099年01月01日}} returns: »« – (empty), if minimal version condition not matched
• If keyword is wikidata, result is version ID registered on Wikidata (2020年01月18日) or local if not found there.
• If keyword is ~, result is empty if local and Wikidata version are the same: ().

Returns:

• Empty, if minimal version condition not matched, or ~ and local version is synchronized.
• Version ID if no parameter, or if wikidata, or local if not found there, or not synchronized.

Limited to:

• Template:URN or similar

The functions described above can be used by other modules, but are supposed for development and management purposes only. The URIutil library functions are a better solution for productive rendering.

local lucky, URNtemplate = pcall( require, "Module:Vorlage:URN" )
if type( URNtemplate ) ~= "table" then
 -- In the event of errors, URNtemplate is an error message.
 return "<span class=\"error\">" .. URNtemplate .. "</span>"
end

Subsequently there are available:

URNtemplate.test( argsF, argsT )

Development interface

Parameters as for f:

1. argsF
   table; list with #invoke parameters
   • .errNS might be string or sequence table with number
2. argsT
   table; list with template transclusion parameters

returns:

• string with external link or error message

URNtemplate.failsafe( atleast )

Versioning interface

1. atleast
   optional
   nil or minimum version or wikidata or ~ for synchronisation

returns: Version ID as string or false

• Module:URIutil
  • Module:URIutil/urn
• Module:TemplUtl (recommended)

Follow the steps:

1. Copy module code of Module:Vorlage:URN into your project.
   • Choose any appropriate name for the module.
2. Register this module at d:Q52365013.
3. Ensure that Module:URIutil (d:Q19644443) is available for your project.
   • If not yet, provide a copy according to installation guide.
4. Module:URIutil/urn (d:Q20950454) is required as well, see URIutil root module.
5. It is recommended to provide Module:TemplUtl (d:Q52364930) for improved error handling; see installation guide.

There are built-in error messages, currently available in English and German.

• Some few other languages might be incorporated into upstream code.
• For larger number of translations another global multilingual might be implemented.
• That depends on global proliferation.
