Third-party notices
peo's own code (the peo/, container/ and tests/ directories, the
Containerfile, compose.yaml and pyproject.toml) is licensed under the GNU General Public
License v3.0 or later; see LICENSE.
The container images built from this repository also contain the third-party
software below. None of it is stored in this repository: it is downloaded when
an image is built. Inside the images, license texts are collected under
/usr/share/doc/peo/.
The full image (the default build target) contains everything in the table. The
slim image (--target slim) contains only neo4j-browser and the JavaScript
libraries bundled into it, the Debian base system with Python 3 and
python3-psycopg, and the Python packages peo depends on.
compose.yaml does not bundle PostgreSQL, AGE or pgAdmin: it runs the
apache/age and dpage/pgadmin4 images from Docker Hub, which come with their
own license information.

Source code
- neo4j-browser is licensed under the GPL, which requires the complete
corresponding source to accompany the built application. The image contains
it as
/usr/share/doc/peo/neo4j-browser/neo4j-browser-source.tar.gz, an archive of the exact commit that was built. Its dependencies are pinned by theyarn.lockinside that archive, and the build steps are in this repository'sContainerfile. - peo itself ships as Python source code in the
/opt/peo/venv/virtual environment, next to the Python packages it depends on. This repository has the rest. - Debian packages: source is available from sources.debian.org and the Debian archive.
Interoperability
The peo bridge implements the Bolt protocol and PackStream format from their
public specifications so that unmodified Neo4j clients can connect. It contains
no source code from Neo4j. To work with those clients it reports itself as
"Neo4j" with a Neo4j version number, and it recognises the exact query strings
that neo4j-browser sends; tests/smoke_test.py repeats some of those query
strings to check compatibility.
Trademarks
Neo4j is a trademark of Neo4j, Inc. PostgreSQL is a trademark of the PostgreSQL Community Association. Apache, Apache AGE and the Apache feather logo are trademarks of The Apache Software Foundation. pgAdmin is a trademark of the pgAdmin Development Team. peo is not affiliated with or endorsed by any of them; the names are used only to identify the software it works with.
