B2HANDLE

The b2handle Python library is a client library for interaction with a Handle System server, using the native REST interface introduced in Handle System 8. The library offers methods to create, update and delete Handles as well as advanced functionality such as searching over Handles using an additional search servlet and managing multiple location entries per Handle.

The library currently supports Python 2.6, 2.7, 3.5, 3.6 and 3.7, and requires at least a Handle System server 8.1. The library requires OpenSSL v1.0.1 or higher.

Test Coverage and Continuous Integration

Test status of the devel branch:

B2Handle has a unit test coverage of approximately 90%. Every addition to the devel branch is automatically unit tested. The test can be found in b2handle/tests and easily run using the command "python main_test_script.py". For the current test coverage, please click on the badge and link above.

In addition to the unit tests, integration tests cover the reading, writing and searching of handles. As these needs credentials and write access to a real server, these are not run on GitHub. However, every user with access to a handle server can add their own credentials and run the integration tests in his/her system (using the command "python main_test_script.py testtype write", or "read", or "search", or all three).

Installation and use

Build an egg:

python setup.py bdist_egg

Install the library via pip:

pip install <egg file>

For more information on the methods offered by the library, please consult the technical documentation. The documentation also contains information on how to set up correct certificates for the Handle Server so it accepts modification REST requests and how to set up client authentication using public keys.

Docker support

The library can also be used in combination with Docker. The Dockerfile contains instructions for building a Docker image with the B2HANDLE library installed.
