The KIM development team is pleased to announce the release of version 0.2.0 of the KIM application programming interface (API). By conforming to this API, an atomistic simulation code will seamlessly work with any KIM-compliant interatomic model written in any supported language. The interface is computationally efficient and often requires relatively minor changes to existing codes.
Version 0.2.0 is a fully functioning API. It has the following main features:
(See the CHANGELOG and README files described below for more information on these features.) The distribution includes the API code, examples of simulation codes (Tests) and interatomic models (Models) and documentation. The purpose of this release is to familiarize users with how the API works and to get feedback to help guide the design of future releases. Note that this is an "alpha" release in computer science terms (http://en.wikipedia.org/wiki/Software_release_life_cycle). Additional features will be added to the next release (see below) which may not be fully-downward compatible.
