owl2shacl 0.2.0

A CLI tool that tries to convert simple OWL ontologies into SHACL shapes. OWL ontologies define logical relationships. SHACL shapes define a data scheme, and allow to validate data against them. Strictly speaking, as these are different things, such a conversion is thus illegal/wrong in the ideological/theoretical sense. Thus this tool is not generally applicable, but only under the circumstance, that the OWL ontology is actually written as a data specification - if it is understood as a kind of distributed database schema, rather then for logical inference. Not only that, but it also has to conform to certain, very narrow rules, and only a few basic properties are translated into SHACL; the rest is ignored.

A [CLI] tool that tries to convert simple [OWL] ontologies into [SHACL] shapes.
OWL ontologies define logical relationships.
SHACL shapes define a data scheme, and allow to validate data against them.
Strictly speaking, as these are different things,
such a conversion is thus illegal/wrong in the ideological/theoretical sense.
Thus this tool is not generally applicable, but only under the circumstance,
that the OWL ontology is actually written as a data specification -
if it is understood as a kind of distributed database schema,
rather then for logical inference.
Not only that, but it also has to conform to certain, very narrow rules,
and only a few basic properties are translated into SHACL;
the rest is ignored.

## Supported OWL ontologies

Roughly speaking,
this tool supports a 25% subset of [OWL Lite](
https://www.w3.org/TR/2004/REC-owl-features-20040210/#s2.1),
plus some third party properties.

More specifically:

## How to compile

You need to install Rust(lang) and Cargo.

Then get the whole repo plus git sub-modules with:

```bash
git clone --recurse-submodules https://codeberg.org/elevont/owl2shacl.git
cd owl2shacl
```

Then you can run:

```bash
cargo build --release
```

If all goes well, the executable can be found at `target/release/owl2shacl`.

## Get the tool

As for now, you have two choices:

1. [Compile it](#how-to-compile) yourself
1. Download a Linux x86\_64 statically linked binary from
   [the releases page](https://codeberg.org/elevont/owl2shacl/releases)
