User:Larivact/Which annotation syntax to choose

• There are, roughly, 4 ways to build a semantic-template:

  1. simple-annotations (e.g. [[foo prop::value]])

  values displayed formatted (as links / with units, aliased page-titles, etc)

  BUT cannot use values with wiki-syntax (e.g. [[Description::See [[Help:FAQ]]]]) does not parse) even if parser strict mode is disabled (note: default is enabled).

  2. #set annotations + accompanied by respective #show query

  Can set any value, displayed formatted automatically,

  BUT it is expensive (if there many annotations + #show-queries on a page).

  3. #set annotation using the template parameter.

  Can set any value, fast,

  BUT needs manual templating work to format the displayed values (and not always working).

  4. Massive #set annotations, and a single #ask query

  Can set any value, automatically formatted, fast

  BUT #ask needs templating work for the whole results (i.e. may require elaborate use of result-formatting templates).
