Turtle Canon¶

It's turtles all the way down

A tool for canonizing Turtle (.ttl) ontology files.

The domain standardized tool for editing and creating ontologies is Protégé. The Turtle (.ttl) file format is a format based on XML and OWL, which is considered one of the most readable formats for OWL ontology files. However, Protégé writes the order of ontology entities differently depending on the version, this tool mitigates this by running the file through a canonizing parser that ensures the classes are sorted and listed in the same way, always.

The main use case for developing this tool is when developing ontologies utilizing versioning tools such as git, svn or similar, which are single character diff-sensitive.

Install¶

The tool is written for Python 3.10, so one needs at minimum Python 3.10 installed to run it at this stage. The plan is to make a stand-alone executable for each of the major OS'.

Install via PyPI (stable version, recommended):

python3.10 -m pip install turtle-canon

Install via GitHub (development version):

python3.10 -m pip install git+https://github.com/CasperWA/turtle-canon#egg=turtle-canon
