FcaBedrock v2.9.999

Final legacy release of the FcaBedrock v2 line, and the first published release since the public v2.8.28 build from 12 June 2014.

FcaBedrock is a Windows desktop tool for converting many-valued data sets into single-valued Formal Contexts for Formal Concept Analysis (FCA). It reads flat CSV / delimiter-separated data and three-column triple data, and writes Burmeister .cxt or FIMI .dat output.

Release status

2.9.999 is the final planned update of the legacy v2 tool and the first published release after 2.8.28 (12 June 2014), the last previously published public v2 build.

The legacy v2 line will be superseded by FcaBedrock vNext, which is under development. The first vNext release is planned for Q3 2026. Updates and release information for vNext will be published at https://github.com/trashr0x/fcabedrock.

  5. Save a .bed file if you want to keep that interpretation for reuse.
