wiki](https://github.com/OpenTreeOfLife/reference-taxonomy/wiki/Interim-taxonomy-file-format),
on github.
## Build script
The reference taxonomy is an algorithmic combination of several
source taxonomies. For code,
see the
source code repository.
Version 2.8 was generated using
[commit f2ee381ef3c2d1806cd3d4b311124fb590aa2a42](https://github.com/OpenTreeOfLife/reference-taxonomy/commit/f2ee381ef3c2d1806cd3d4b311124fb590aa2a42).
Where taxonomies conflict regarding taxon relationships, they are
resolved in favor of the higher priority taxonomy. The priority
ordering is as given below.
