pyemllib 0.1.0

Python lib to deal with EML (Ecological Metadata Language)

pyemllib

This package is a python lib to help dealing with EML - Ecological Metadata Language.

It's built uppon dataclasses generated with xsdata from EML xsd hence heavily relies on xsdata capabilities

For history reasons, i also provide the former pyxb and generateDS (built with py38) that i used to use on my projects but that i now find more cumbersome to use than the dataclass implementation. They might be useful anyway !!

NB: This lib is currently developped under a local gitlab forge and will be release on github on important releases

• Github repository: https://github.com/jusana/pyemllib/
• Documentation https://jusana.github.io/pyemllib/

Main features

• Deserializes EML files to python objects
• Serializes pure python objects to EML as XML string / files
• Checks validity of EML generated against xsd
• Generates a markdown/html DataPaper from suitable EML files

Very simple usage

from emllib import EMLizer

# instantiate EML object document
my_eml = EMLizer(package_id="ID", title="Mon titre", lang="fr", creator="Mon Createur", abstract="Mon abstract")

# print EML xml formatted string
print(my_eml.to_string())

# dump EML xml formatted to file
my_eml.to_file('path/to/file/eml.xml')

# Inspect validity
if my_eml.validate():
    print("This EML file seems valid")
else:
    print("This EML file does not seem valid!")

Recommended usage

The EMLizer helper class is just a wrapper to help quickly basic EML files. Nevertheless in more complex or sophisticated situations, i recommend to use the dataclass API directly under emllib.dataclass.eml220
