Future work to improve PoreMatMod.jl includes: improve the efficiency of the subgraph matching algorithm by parallelization and/or implementation of faster algorithms [ ]; implement inexact subgraph matching (subgraph similarity searching) [ ]; handle replacement fragments which (a) require unit cell expansion/contraction and/or (b) have no overlap with the query fragment; consider edge metadata (e.g., bond order) in the definition of a subgraph match; include spatial overlay criteria in the matching algorithm to discern among spatial isomers and conformations; and leverage crystallographic point group symmetries to, when enumerating e.g. functionalized MOF analogues, prevent generation of symmetry-degenerate structures.
