LOSH OKH tool

A CLI tool to deal with OKH data files. Its main functionalities are:

• validation of, and
• conversion between

different formats of OKH

Definitions

• LOSH: A Library of Open Source Hardware - technical documentation in an open graph database.
• OKH: Open Know-How - A standard for OSH project meta-data.

Intro

This repo contains two pieces of software:

• okh-tool
• fetch-n-conv-v1

and it uses the OKH JSON-Schemas repo as submodule.

• okh-losh.schema.json
• okh-v1.schema.json

The okh-tool can:

• convert manifest files from one version of the OKH standard to an other
• validate manifest files of the different OKH standard versions. It does so by using the above mentioned JSON Schema files.

The fetch-n-conv-v1 script will:

1. fetch publicly registered OKH v1 manifest files
2. clean them up
3. validate them
4. convert them to OKH LOSH (aka "v2")
5. validate the generated OKH LOSH manifest files

Usage

Conversion and Validation

The okh-tool is written in rust, and can be compiled like this:

cargo build --release

This will produce the stand-alone binary tool in target/release/okh-tool.

To run it, you have these options for conversion:

$ okh-tool conv --help
okh-tool-conv 0.1.0



Converts one format into an other (currently only OKH-v1 to OKH-LOSH)

USAGE:
    okh-tool conv [OPTIONS] <INPUT> [OUTPUT]

ARGS:
    <INPUT>     The input file or dir path
    <OUTPUT>    The output file or dir path

OPTIONS:
    -c, --continue     If the input path is a directory, continue processing further files, even
                       after an error
    -h, --help         Print help information
    -o, --overwrite    If the outout file alreayd exists, overwrite it, instead of skipping the
                       conversion
    -r, --recursive    If the input path is a directory, search for input files recursively
    -V, --version      Print version information

and these for validation:

$ okh-tool val --help
okh-tool-val 0.1.0



Validates manifest files for validity using JSON Schema (currently supports OKH-v1 and OKH-LOSH)

USAGE:
    okh-tool val [OPTIONS] <INPUT>

ARGS:
    <INPUT>    The input file or dir path

OPTIONS:
    -c, --continue                     If the input path is a directory, continue processing further
                                       files, even after an error
    -h, --help                         Print help information
    -o, --okh-version <okh-version>    If the input path is a directory, search for input files
                                       recursively [possible values: v1, losh]
    -r, --recursive                    If the input path is a directory, search for input files
                                       recursively
    -V, --version                      Print version information

Fetching and converting OKH v1

Once you have the above described okh-tool ready (it is required by this script), you may just start the whole process like follows; but be wary, this may take around 3h (99+% of which is spent downloading). The already downloaded files will not be re-downloaded when you abort the process and start a-new.

./fetch-n-conv-v1
