spdx3query 0.0.2

Query SPDX 3 data files

spdx3query

Command line tool for querying SPDX 3 files

Installation

spdx3query can be installed using pip:

python3 -m pip install spdx3query

Usage

spdx3query takes one or mode SPDX 3 JSON files as input using the -i option and then a subcommand to query information about it. For example, this command will list all Build objects found in my-sdpx.spdx.json:

spdx3query -i my-spdx.spdx.json find --type build_Build

There are many commands that spdx3query supports. For a list of commands, see spdx3query --help. Each command also implements a --help which can provide additional information about what it does, for example spdx3query find --help

Interactive mode

In addition to the top level subcommands of sdpx3query, there is also an interactive mode where commands can be run. This can be useful for interactively exploring SPDX 3 files, particularly if they are very large as the dataset only needs to be loaded once. To enter interactive mode, the interactive subcommand is used, for example:

spdx3query -i my-spdx.spdx.json interactive

From the prompt, any query subcommand can be run in the same way as if it had been specified on the command line, for example:

> find --type build_Build

Object Mnemonic Handles

Objects in SPDX 3 are often assigned IRIs as identifiers (either in the @id or spdxId property, depending on the object). These IRI names are often very long and can be difficult to type in correctly when performing queries on a data file. To aid in identifying objects, spdx3query assigns a mnemonic to each device that can be used in place of the identifier. The mnemonic uses words from the BIP 39 word list, and by default uses 3 terms. If you are dealing with a large datafile, you can increase the number of terms using the --handle-terms argument to spdx3query. The mnemonic handle is based on a hash of the actual ID, and therefore is stable even when loading the same file multiple times.

As an example, you can see the mnemonic handle for the following build object is "chest-acoustic-phone"

$ spdx3query -i bitbake.spdx.json find --type build_Build --show
Loaded 18 objects in 0.01s
Found 1 object(s):

build_Build - 'chest-acoustic-phone'
  spdxId: 'http://spdx.org/spdxdoc/bitbake-addba517-4804-5ae3-87c2-0c3a1a5812ba/bitbake/2ae7c23f5bf50e79d5c97b3a3f2294bb'

This means that you can can use this mnemonic handle in place of the actual spdxId to reference this object, e.g.:

spdx3query -i bitbake.spdx.json show chest-acoustic-phone

For objects that do not have an ID, a mnemonic handle will also be assigned, but it will have a LOCAL- prefix prepended to it. These handles are not guaranteed to remain the same between different invocations of spdx3query. For example:

$ spdx3query -i bitbake.spdx.json find --type CreationInfo
Loaded 18 objects in 0.01s
Found 1 object(s):
CreationInfo - 'LOCAL-stereo-window-riot'

Development

Development on spdx3query can be done by setting up a virtual environment and installing it in editable mode:

python3 -m venv .venv
. .venv/bin/activate
pip install -e .[dev]

Tests can be run using pytest:

pytest -v
