Transparent Research Object utils

This package provides a set of utilities for working with Transparent Research Objects (TROs). It is designed to be used in conjunction with the TRO specification.

It uses the Click library to define commands and options. Here's a summary of the main features:

1. Global Options: The script defines several global options that can be used with any command, such as --declaration, --profile, --gpg-fingerprint, --gpg-passphrase, --tro-creator, --tro-name, and --tro-description. These options can be used to specify various parameters for the TRO.

2. Commands: The script defines several commands, each with its own set of options and arguments. The commands include:

   • verify: Verifies that the TRO is signed and timestamped correctly.

   • arrangement: Manages arrangements in the TRO. It has subcommands like add (adds a directory as a composition to the TRO) and list (lists available arrangements in the TRO).

   • composition: Manages compositions in the TRO. It has a subcommand info that gets info about the current composition.

   • performance: Manages performances in the TRO. It has a subcommand add that adds a performance to the TRO.

   • sign: Signs the TRO.

   • report: Generates a report of the TRO.

3. TRO Interaction: The script interacts with the TRO using the TRO class from the tro_utils module. It uses this class to create a new TRO, add arrangements and performances to the TRO, verify the TRO, and generate a report of the TRO.

Installation

Pre-requisites

Before you begin, you need to have the following installed on your system:

• GPG
• OpenSSL
• Python 3.8+

You can do this by running the following commands:

$ sudo apt-get install gnupg openssl python3 python3-pip    # on Debian/Ubuntu
$ brew install gnupg openssl python3                        # on macOS with Homebrew

Example Usage

Assumes that:

• this package is installed
• your GPG key is present
• trs.jsonld is available and defines TRS capabilities (see below for an example)

Example workflow:

$ cd /tmp
$ cat trs.jsonld
  {
    "rdfs:comment": "TRS that can monitor netowork accesses or provide Internet isolation",
    "trov:hasCapability": [
      {
        "@id": "trs/capability/1",
        "@type": "trov:CanRecordInternetAccess"
      },
      {
        "@id": "trs/capability/2",
        "@type": "trov:CanProvideInternetIsolation"
      }
    ],
    "trov:owner": "Kacper Kowalik",
    "trov:description": "My local system",
    "trov:contact": "root@dev.null",
    "trov:url": "http://127.0.0.1/",
    "trov:name": "shakuras"
  }
$ export GPG_FINGERPRINT=...
$ export GPG_PASSPHRASE=...
$ git clone https://github.com/transparency-certified/sample-trace-workflow /tmp/sample
# It's sufficient to pass the profile only once
$ tro-utils --declaration sample_tro.jsonld --profile trs.jsonld arrangement add /tmp/sample \
    -m "Before executing workflow" -i .git
  Loading profile from trs.jsonld
$ tro-utils --declaration sample_tro.jsonld arrangement list
  Arrangement(id=arrangement/0): Before executing workflow
$ pushd /tmp/sample && \
  docker build -t xarthisius/sample . && \
  ./run_locally.sh latest xarthisius && \
  popd
$ tro-utils --declaration sample_tro.jsonld arrangement add /tmp/sample \
    -m "After executing workflow" -i .git
$ tro-utils --declaration sample_tro.jsonld arrangement list
  Arrangement(id=arrangement/0): Before executing workflow
  Arrangement(id=arrangement/1): After executing workflow
$ tro-utils --declaration sample_tro.jsonld performance add \
  -m "My magic workflow" \
  -s 2024-03-01T09:22:01 \

  -c trov:InternetIsolation \
  -c trov:InternetAccessRecording \
  -a arrangement/0 \
  -M arrangement/1
 $ tro-utils --declaration sample_tro.jsonld sign
 $ tro-utils --declaration sample_tro.jsonld verify
