I would like to map which animal species are slaughtered at slaughterhouses. In addition, I am interested in recording which of the official EU slaughterhouse categories a facility belongs to.
Currently I have been using:
industrial=slaughterhouse livestock=pig;sheep
However, according to the wiki, livestock=* appears to be primarily intended for buildings that house animals.
I am therefore wondering whether something like the following would be more appropriate:
Other tags are used alongside very different tags (ie Key:male - OpenStreetMap Wiki with hairdressers and toilets) although I don’t know if that is considered to be encouraged.
IMO having both livestock and animal would be confusing.
How easy is it to identify the animal type without looking at the documentation? If it’s impossible then maybe using using the regulation category would be best.
The wiki necessarily represents current usage (and generally only an aspect of it), and not future extensions of tag use. It also tends to be a mere description of practice, not definitionally authoritative documentation.
Which is a wordy way of giving my opinion that applying a livestock= tag to a slaughterhouse is exactly what we should be doing: deploying existing tags that have acquired a clear meaning into new contexts, rather than inventing new tags for new contexts.
Go for it.
(I’d avoid “species” for similar reasons. Established practice is to give the Latin name as the value for that key: helpful for trees, overkill - ahem - for slaughterhouses)
livestock= : Unsuitable as not all slaughtered animals viz =wild_game to be covered are raised domesticated animals for the definition
slaughterhouse:*=
*:species= : =pig;sheep would need to be species:en=
*:category= : There’s no reason to follow EU (and many reasons these are bad in general) , and *:category= is still not meaningful. designation= / designation:EU= should be used for that.
animal= is simple to start with. However, there are indeed some problems with it being used for features ( =horse_walker ), and other facilities have used other specific attributes perhaps for multi-functionality ( animal_keeping= , while animal_keeping:type= has a meaningless suffix).
slaugherhouse= would have various potential uses. Could be the slaughtering method (eg =gas vs =electric_stun etc), as there are options for other attributes ( automated= , air_conditioning= , diet:*= ). There seems to be tens of craft=butcher to avoid industrial=slaughterhouse for small-scale non-industrialized ones.
Wild game is by definition not livestock, at least in ordinary English usage. Livestock is live animals that count as stock = capital you possess. Wild game is not something you possess, until it’s shot dead.
Thank you everyone for your input and suggestions.
Based on some feedback here, I have written a new proposal that explores a more normalized tagging approach, separating the animal itself from the products and practices associated with it. There is now also the question of whether animal=* could be a better key than livestock=* , as it is more neutral and is used more often. Additional tags can be used to show what the animal is used for.
To keep the discussion focused in one place, I would appreciate further feedback in the new topic:
