This repository contains general Python functions for PREMIS 2.x XML handling.
Installation and usage requires Python 3.9 or newer. The software is tested with Python 3.9 on AlmaLinux 9 release.
Installation on Linux distributions is done by using the RPM Package Manager. See how to configure the PAS-jakelu RPM repositories to setup necessary software sources.
After the repository has been added, the package can be installed by running the following command:
sudo dnf install python3-premis
In python, import the library with:
import premis
All the functions can now be used with calling premis.<function>.
For example, the fixity() function in object_base.py can be used with:
fix_elem = premis.fixity('MD5', '...')
This creates a PREMIS <fixity> element with <messageDigestAlgorithm> and <messgeDigest> to fix_elem as lxml.etree.
Please, see the PREMIS documentation for more information: https://www.loc.gov/standards/premis/
