 # Summary
 
-Raphtory is a platformß for building and analysing temporal networks. The library includes methods for creating networks from a variety of data sources; algorithms to explore their structure and evolution; and an extensible GraphQL server for deployment of applications built on top. Raphtory's core engine is built in Rust, for efficiency, with Python interfaces, for ease of use. Raphtory is developed by network scientists, with a background in Physics, Applied Mathematics, Engineering and Computer Science, for use across academia and industry.

 Besides the aforementioned packages, few open access tools have been developed for the mining of temporal networks, with the existing solutions focusing on specific sub-problems within the space. Those which have attempted to generalise to all temporal network analysis are either actively under development, but too preliminary to use in production, or have been abandoned due to lack of funding or changing research goals. 
 
-As examples of these three categories: Pathpy is a Python package for the analysis of time series data on networks, but focuses on extracting and analysing time-respecting paths [@hackl2021analysis]. Similarly DyNetX [@DyNetX], a pure python library relying on networkX, focuses on temporal slicing and the computation of time-respecting paths. The recently released Reticula offers a range of methods developed in C++ with a Python interface [@badie2023reticula]. Phasik [@lucas2023inferring], written in Python, focuses on inferring phases from temporal network data. EvolvingGraphs.jl [@zhang2015dynamic], RecallGraph [@RecallGraph] and Chronograph [@Chronograph] all saw significant work before development was halted indefinitely.

 Raphtory is a valuable addition to this ecosystem for the following reasons. Originally developed in Scala [@steer2020raphtory], its current core is entirely written in Rust. This is to ensure fast and memory-efficient computation that a pure python implementation could not achieve, and to handle the sheer volume of temporal network data, which often dwarfs that of an equivalent static network.
