Templates/Taxonomy
 |  This page is currently a draft. More information pertaining to this may be available on the talk page. Translation admins: Normally, drafts should not be marked for translation. |
Scope[edit]
Initial mandate: "Create a bit of a taxonomy of the most commonly used templates: What are they for, do we currently provide a great experience editing them visually, and if not, can this be done on the basis of templates, or should we look at a different solution".
Classifications[edit]
Purpose[edit]
Questions:
- What are templates used for?
- What is a good use of a template? A poor use?
Leads:
- Look at template categories: w:Category:Wikipedia templates (d:Q3740), w:Category:Wikipedia template categories (d:Q3760)
- Look into breakdown of templates by namespace
Construction[edit]
Questions:
- What are the components and building blocks of templates?
- How are templates built?
- Who creates and edits templates?
- What is a well-constructed template? What are poorly-constructed templates?
Leads:
- Break down templates by whether:
- they have parameters
- they have a fixed or variable number of parameters
- they use parser functions
- including expensive parser functions
- they use Lua
- they add a category
- they contain any CSS (do they have a
style?) - they're self-contained (do they close all the tags they opened?)
- they have parameters
- Look into templates authors:
- Look up contribution statistics in the template namespace
- Look into protection levels for templates
Output & usage[edit]
Questions:
- What are the most widely used templates?
- What are the templates used the most frequently? (cumulative usage in pages)
- What does the crosswiki landscape of templates look like? How much do interwiki versions of a template overlap?
- How much of the template population is documented for use?
- What is the case for substitution?
Leads:
- Special maintenance pages like Special:MostTranscludedPages (not limited to templates),
- Break down templates by whether:
- they have a
/docsubpage or similar - they have TemplateData
- they have interwikis
- they have a
- Look into real estate occupied by templates (individually and cumulatively per page)
- Use Parsoid dumps for labeled HTML
Performance[edit]
Questions:
- How much of the template population is expensive in terms of performance?
Leads:
- w:Wikipedia:Template limits, preprocessor node count, etc.
Initial queries[edit]
- Number of all templates on en.wikipedia (599,646 as of 2015-01-05)
- Number of non-redirect templates on en.wikipedia (482,020 as of 2015-01-05)
- Number of templates using a Lua module on en.wikipedia (379,910 as of 2015-01-05)
- Templates/Taxonomy/Most transcluded/wikipedia/en/2015-01-05: An up-to-date version of w:en:Special:MostTranscludedPages. This includes all namespaces, so mixes templates and Lua modules
- Templates/Taxonomy/Most transcluded templates/wikipedia/en/2015-01-05: An up-to-date version of w:en:Special:MostTranscludedPages restricted to templates (namespace 10).
