Template:Uses from

Uses: {{{1}}}Property "Uses library" (as page type) with input value "{{{1}}}" contains invalid characters or is incomplete and therefore can cause unexpected results during a query or annotation process.[[Category:{{{1}}}]] (Component[s]: {{{2}}})

This template is intended to handle the case where a library has many components within it (examples of this include CPAN, RubyGems and Tcllib). It has two required parameters: {{uses from|library|component}}. The library is the name of the overall library of components (which should also be the name of a category here on RC) and the component is the name of the component within it (which can be almost any string).

Discussion

This template is derived from {{tcllib}}, and seeks to have a similar aim, except more generically, and as a potential eventual replacement for {{libheader}} and {{works with}}. (And {{tcllib}}, if it achieves sufficient functionality.)

Design goals in common with {{tcllib}}, {{libheader}} and {{works with}}:

• Use {{{1}}} as the library name.

Other ultimate goals that make its behavior variously different from current {{tcllib}}, {{libheader}} and {{works with}}:

• Avoid using MW categories. Use semantic properties instead. (MW categories have particular behavior when used in semantic queries.)
• Apply the semantic property uses::{{{1}}}
• Accept an undefined number of additional named arguments as components of that library. (var name might be componentN) Add a semantic property to the page indicating that it uses {{{1}}}.
  • uses {{{1}}} component::{{{component1}}}, {{{component2}}}, etc...
• Accept library version as a single named argument. (var name might be version) Tag the transcluding page as using that version of library {{{1}}}.
  • uses {{{1}}} version:{{{version}}}.
• For each {{{componentN}}} supplied, if any, apply
  • uses {{{1}}} version {{{version}}} component::{{{componentN}}}.
  • uses {{{1}}} component {{{componentN}}} version::{{{version}}}.

The richer the relationships we can define, the more powerful the search options we'll have available.

(Unless someone can figure out a better way to apply pagename/libname/component/version with the semantic properties.)
