we really need some kind of subdivision tools, as this shows https://twitter.com/mdsumner/status/1255702228171546624 probably it's related to the barycentric stuff - as in put segmentized vertices along edges, but use interpolation...

This has been confusing me this week as I keep thinking "worldll" is polygons: ```R silicate::TRI(quadmesh::worldll) Error in .local(x, ...) : invalid layer names ``` There's really no problem to...

guidelines and rationale

We need an overall guiding document for principles. Motivation is coming out of anglr, for when we only have *implicit topology* i.e. for a surface in a sf polygon, what...

dm as the data model engine

This looks very promising: ```R ## devtools::install_github("krlmlr/dm") library(silicate) sc % as_dm() %>% cdm_add_pk(object, object_) %>% cdm_add_fk(object_link_edge, object_, object) %>% cdm_add_pk(edge, edge_) %>% cdm_add_fk(object_link_edge, edge_, edge) %>% cdm_add_pk(vertex, vertex_) %>% cdm_add_fk(edge,...

these need to come out for all models, and not be documented with sc_edge/sc_node: - [x] PATH return poly/line start end of all *paths* - [ ] PATH0 (needs to...

robustness to relational assumptions

silicate is currently very naive in what it tries to do, and if there's a disconnected between the set of `object$object_` and `object$object_link_edge` then conversions to `SC0` and so on...

Don't merge in test-vapour0.8.5 haha There's a lot in master that overtakes that, all that's needed is to have conversion of raw values to integer, and the NEWS. Incorporate the...
