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

It's built uppon [dataclasses](https://docs.python.org/3.9/library/dataclasses.html) generated with [xsdata](https://github.com/tefra/xsdata) from [EML xsd](https://eml.ecoinformatics.org/schema/) 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


```python
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().bool:
    print("This EML file seems valid")
else:
    print("This EML file does not seem valid!")
    my_eml.validate().reason

```


## 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`
