This table of tables lists local language date names and fallback English date names.
The code in Date_validation will look first in the local table for valid date names.
If date names are not found in the local table, the code will look in the English table.
 
Because citations can be copied to the local wiki from en.wiki, the English is
required when the date-name translation function date_name_xlate() is used.
 
In these tables, season numbering is defined by
Extended Date/Time Format (EDTF) Specification (https://www.loc.gov/standards/datetime/)
which became part of ISO 8601 in 2019.  See '§Sub-year groupings'. The standard
defines various divisions using numbers 21-41. CS1|2 only supports generic seasons.
EDTF does support the distinction between north and south hemisphere seasons
but CS1|2 has no way to make that distinction.
 
33-36 = Quarter 1, Quarter 2, Quarter 3, Quarter 4 (3 months each)


The standard does not address 'named' dates so, for the purposes of CS1|2,
Indic script makes use of zero width joiner as a character modifier so zwj
Easter and Christmas are defined here as 98 and 99, which should be out of the

Also here is a pattern that recognizes stripmarkers that begin and end with the
delete characters.  The nowiki stripmarker is not an error but some others are
because the parameter values that include them become part of the template's
metadata before stripmarker replacement.

Indic script makes use of zero width joiner as a character modifier so zwj
characters must be left in.  This pattern covers all of the unicode characters
for these languages:

Kannada 0C80–0CFF – https://unicode.org/charts/PDF/U0C80.pdf
Malayalam 0D00–0D7F – https://unicode.org/charts/PDF/U0D00.pdf

This configuration file contains various data that controls the functioning of Module:Citation/CS1 and hence, the way that Lua-based citations are generated.

It has several sections, among which are:

  1. Translation tables that contain most of the literal strings that may be included in Lua-based citations.
  2. A list of error conditions specifying what text to display, categories to include (if any), and what help page section to refer to when errors are detected
  3. A list of ID handlers specifying the recognized document IDs, such as ISBN, DOI, etc., and how to format them.

These files comprise the module support for CS1 | CS2 citation templates:

  This table of tables lists local language date names and fallback English date
  names. The code in Date_validation will look first in the local table for
  valid date names. If none are found in the local table, the code will look in
  the English table, which is required when the date-name translation function
  date_name_xlate() is used.

  In these tables, season numbering is defined by Extended Date/Time Format
  (EDTF) Specification <https://www.loc.gov/standards/datetime/>, which became
  part of ISO 8601 in 2019; see "§ Sub-year groupings". The standard defines
  various divisions using numbers 21-41. CS1|2 only supports generic seasons.
  EDTF does support the distinction between north and south hemisphere seasons,
  but CS1|2 has no way currently to make those distinctions.

  33-36 = Quarter 1, Quarter 2, Quarter 3, Quarter 4 (3 months each).

  The standard does not address "named" dates, so, for the purposes of CS1|2,
  Easter and Christmas are defined here as 98 and 99, which should be out of the
  ISO 8601 (EDTF) range of uses for a while.

  local_date_names_from_mediawiki is a boolean. When set to:
    true  – fetch local month names from MediaWiki for both
            date_names["local"]["long"] and date_names["local"]["short"];
            this will unconditionally overwrite manual translations.
    false – do *not* fetch local month names from MediaWiki.

  Caveat lector: There is no guarantee that MediaWiki will provide short month
    names. At your wiki you can test the results of the MediaWiki fetch in the
    debug console with this command (the result is alpha sorted):
        =mw.dumpObject (p.date_names["local"])

  While the module can fetch month names from MediaWiki, it cannot fetch the
  quarter, season, and named date names. Those must be translated manually.

This table holds non-printing or invisible characters indexed either by name or
by Unicode group. Values are decimal representations of UTF-8 codes.  The table
is organized as a table of tables because the Lua pairs keyword returns table
data in an arbitrary order.  Here, we want to process the table from top to bottom
because the entries at the top of the table are also found in the ranges specified
by the entries at the bottom of the table.

Also here is a pattern that recognizes stripmarkers that begin and end with the
delete characters.  The nowiki stripmarker is not an error but some others are
because the parameter values that include them become part of the template's
metadata before stripmarker replacement.

	prefix: the first part of a URL that will be concatenated with a second part which usually contains the identifier
	suffix: optional third part to be added after the identifier
	encode: true if URI should be percent-encoded; otherwise false
	COinS: identifier link or keyword for use in COinS:
		for identifiers registered at info-uri.info use: info:.... where '...' is the appropriate identifier label 
		for identifiers that have COinS keywords, use the keyword: rft.isbn, rft.issn, rft.eissn
		for |asin= and |ol=, which require assembly, use the keyword: url
		for others make a URL using the value in prefix/suffix and #label, use the keyword: pre (not checked; any text other than 'info', 'rft', or 'url' works here)
		set to nil to leave the identifier out of the COinS
	separator: character or text between label and the identifier in the rendered citation
	id_limit: for those identifiers with established limits, this property holds the upper limit
	access: use this parameter to set the access level for all instances of this identifier.
		the value must be a valid access level for an identifier (see ['id-access'] in this file).
	custom_access: to enable custom access level for an identifier, set this parameter
		to the parameter that should control it (normally 'id-access')
