We suggest the following labels:
3D (bulk)
2D (surfaces, slabs, ...) [NOTE: the non-periodic direction must be the third lattice vector, AND be along z]
1D (wires) [NOTE: the periodic direction must be the first lattice vector, AND be along x]
0D (molecules)

Hi @AndresOrtegaGuerrero , were there follow up discussions to move slightly away from
#933 ?
otherwise I would stick to what was decided there if space allows

[AndresOrtegaGuerrero]

[cpignedoli]

I would keep (surfaces, slabs, ...) to leave it open to other cases we do not mention.

OK from my side. Automatic detection of periodicity using the function suggested by @giovannipizzi (P1 https://github.com/orgs/aiidalab/projects/17/views/1?pane=issue&itemId=88010088) will follow as a separate PR

[giovannipizzi]

I would add NOTE: in bold before the bullet points

@cpignedoli @giovannipizzi Like this figure above is correct ?

[AndresOrtegaGuerrero]

[cpignedoli]

Reflects what we discussed so far.

[giovannipizzi]

Just to be sure, both requirements are needed (both being the 3rd lattice vector, and being along z), right?

OK to keep as it is and if people complain, we make it even clearer
