Agreeing on optional user interface hints in templates

then let’s make that general templte without these extra annotations and then in another layer/step specialize the general template into more specific ones where we add the annotations to use case specific specialized tempates (e.g. with hints for end user forms). I have tried to highlight this posibility of layering BY USING (several) LAYERS OF TEMPLATES

Indeed. People should keep in mind the fact that adding various kinds of power to a formalism (even if just saying how to use the annotations section) doesn’t mean that all those capabilities have to be used in one layer of templates - you want to do what Erik is saying here, and separate the use of those capabilities into layers of artefacts.

Some way of giving a node a progamming-friendly short meaningful ID/alias so that you don’t need to refer to the entire path in rules etc.

See discussion here. Example of doing this:

    symbol_bindings = <
      ["apgar_events"] =   <
          root = <"/data[id3]/events">
          children = <
              ["apgar_respiratory_value"] =   <"data[id2]/items[id10]/value[id43]/value">
              ["apgar_heartrate_value"] =     <"data[id2]/items[id6]/value[id44]/value">
              ["apgar_muscle_tone_value"] =   <"data[id2]/items[id14]/value[id45]/value">
              ["apgar_reflex_value"] =        <"data[id2]/items[id18]/value[id46]/value">
              ["apgar_skin_colour_value"] =   <"data[id2]/items[id22]/value[id47]/value">
              ["apgar_total_value"] =         <"data[id2]/items[id26]/value[id48]/magnitude">
          >
       >
    >

ADL2.3 doesn’t do this but I would propose that ADL2.5 implements it. Could be short-term faked in annotations.

If you have a template about smoking habits used for data import in a national registry (with data coming from several differnt systems) you may want to use such rules to refuse submissions that have status “never smoked” combined with consumplion “2 packs per day”. So they conditionals are not only for GUI, I believe that’s why they are already part of ADL rule possibilities.

That was our thinking on that.
