02.02. A garden

This says that the garden design idea is a work; the "blueprint" is the expression; the garden is the manifestation. Another view could be that the general design (here as the blueprint) is the work, the selection of specific plants to fill in the blueprint (compatible with the region) is the expression, and the billable job is the manifestation. That could look like this:

Assume that the garden vocabulary's main classes are subclassed to openWEMI.

g:Garden rdfs:subclassOf openwemi:Endeavor .
g:GardenDesign rdfs:subclassOf openwemi:Work .
g:GardenPlan rdfs:subclassOf openwemi:Expression .
g:GardenRealized rdfs:subclassOf openwemi:Manifestation .

An instance might look like:

g:myGarden a g:Garden .

g:myGardenDesign a g:GardenDesign ;
  g:treesNumber "4" ;
  g:mediumBushesNumber "6";
  g:annualsNumber "12" ;
  g:groundCoverSF "8" .

g:myGardenPlan g:implements g:myGardenDesign ;
  a g:GardenPlan ;
  g:treeType "aspen" ;
  g:mediumBushType "camellia" ;
  g:annualType "primrose" ;
  g:groundCoverType "dymondia" .

g:myGardenRealized a g:GardenRealized ;
  g:cost [
    g:treeCost "$600" ;
    g:mediumBushCost "$600" ;
    g:annualCost "$20" ;
    g:groundCoverCost "$100" ;
    g:gardenLabor "$1200"
  ] .
