definition requests: lake sediment and children #127

Lake sediment doesn't have a definition

is it as trivial as 'sediment that is part of a lake'?

saline lake sediment is presumable lake sediment in a saline lake

what about coal mine lake sediment

@cmungall I think these classes are intended to be quite trivial. Should we create "coal mine lake" = 'lake that is located_in coal mine' in order to create a logical def for coal mine lake sediment?

I added some simple textual defs to these classes. We could perhaps add assertions that capture "covers the lake [bottom, bed]"...

pbuttigieg commented 9 years ago

@cmungall This may be a good reason to add sediment generation processes (cosmogenous, terrigenous, biogenous, etc) to the envo process ontology. That way we can make a more useful logical definitions that is along the lines of:

sediment and 'part of' some lake (environment) and 'output of' some 'biogenous sedimentation process'

cmungall commented 9 years ago

Seems reasonable. We'd want to get the process hierarchy in shape a bit more before bringing it into the core. But the axioms connecting things could live purely in the process module for now
