`oaipmh-scythe` is a lightweight [OAI-PMH](http://www.openarchives.org/OAI/openarchivesprotocol.html) client library
written in Python. It has been designed for conveniently retrieving data from OAI interfaces the Pythonic way:
```python
from oaipmh_scythe import Scythe
with Scythe("https://zenodo.org/oai2d") as scythe:
records = scythe.list_records()
next(records)
# <Record oai:zenodo.org:4574771>
```
## Features
- Easy harvesting of OAI-compliant interfaces
- Support for all six OAI verbs
- Convenient object representations of OAI items (records, headers, sets, ...)
- Automatic de-serialization of Dublin Core-encoded metadata payloads to Python dictionaries
- Option for ignoring deleted items
## Requirements
[Python](https://www.python.org/downloads/) >= 3.10
`oaipmh-scythe` is built with:
- [httpx](https://github.com/encode/httpx) for issuing HTTP requests
- [lxml](https://github.com/lxml/lxml) for parsing XML responses
## Installation
You can install `oaipmh-scythe` via pip from [PyPI][pypi-url]:
```console
python -m pip install oaipmh-scythe
```
## Documentation
The [documentation][docs-url] is made with [Material for MkDocs](https://github.com/squidfunk/mkdocs-material) and is
hosted by [GitHub Pages](https://docs.github.com/en/pages).
## Similar Projects
There are a couple of similar projects available on [PyPI](https://pypi.org/search/?q=oai-pmh) and GitHub, e.g. via the
topics [oai-pmh](https://github.com/topics/oai-pmh) and [oai-pmh-client](https://github.com/topics/oai-pmh-client).
Among them are these implementations in Python:
| Project | Description | Last commit |

| [sickle](https://github.com/mloesch/sickle) | `oaipmh-scythe` is a fork of `sickle` |  |
| [pyoai](https://github.com/infrae/pyoai) | `sickle` was inspired by `pyoai` |  |
| [pyoaiharvester](https://github.com/vphill/pyoaiharvester) | oai-pmh harvester CLI |  |
| [ddblabs-ometha](https://github.com/Deutsche-Digitale-Bibliothek/ddblabs-ometha) | oai-pmh harvester with CLI and TUI |  |
| [oai-harvest](https://github.com/bloomonkey/oai-harvest) | uses `pyoai` internally |  |
| [oai-pmh-harvester](https://github.com/MITLibraries/oai-pmh-harvester) | uses `sickle` internally |  |
There are also similar projects available in [Java](https://github.com/topics/oai-pmh-client?l=java) and
