SSSOM-Java is an implementation of the SSSOM standard for the Java language – just a hobby, won’t be big and professional like sssom-py.

It provides a library of Java classes to represent and manipulate SSSOM mappings and mapping sets, and read and write them to and from the SSSOM TSV and JSON serialisation formats. The library includes several additional features; notably, it proposes an ad-hoc filtering and transformation language, named SSSOM/Transform or SSSOM/T, to allow rule-based arbitrary transformation of mappings into any kind of objects.

It also provides a ROBOT plugin to use or generate SSSOM mapping sets as part of a pipeline of ROBOT commands, and a command-line tool to manipulate mapping sets from the command line.
