# Simple OAI-PMH 2.0 Data Provider
|
|
|
|
This is a stand-alone and easy to install data provider for the [Open Archives Initiative's Protocol for Metadata Harvesting (OAI-PMH)](https://openarchives.org/pmh/) written in [PHP](https://php.net/). It serves records in any metadata format from directories of XML files using the directory name as metadata prefix, the filename as identifier and the filemtime as datestamp. 0-byte files are considered deleted records and handled accordingly. Resumption tokens are managed using files. Sets are currently not supported.
|
|
|
|
Just put the records as XML files in the data directory, adjust a few configuration settings and you are ready to go!
|
|
|
|
A demo installation can be found [here](https://demo.opencultureconsulting.com/oai_pmh/?verb=Identify).

## Installation
|
|
|
|
1. Deploy all the files to a webserver.
|
|
|
|
2. Edit `Configuration/Main.php` and adjust the settings according to your preferences.
|
|
|
|
3. Create a subdirectory inside the specified data directory for every format (i. e. `metadataPrefix`) you want to provide.
|
|
|
|
4. Put the records into the respective directories according to their format. Each record has to be a separate XML file with its `identifier` as filename (e. g. 12345678.xml). Optionally you can maintain deletions by keeping 0-byte files for deleted records.
|
|
|
|
5. Congratulations! Now you are running an OAI-PMH 2.0 compatible data provider. You can access the entry point by calling `index.php?verb=Identify` in your browser.

|
## Updating
|
|
|
|
Updating your records from the command line is just as easy with the `update.php` script! The script automatically handles deletions by maintaining 0-byte files for deleted records. Just call `php update.php` and follow the instructions.

## History
|
|
|
|
This project was originally initiated in 2002 by [Heinrich Stamerjohanns](mailto:stamer@uni-oldenburg.de) at [University of Oldenburg](https://www.uni-oldenburg.de/en/). His latest implementation can be still found via the [Internet Archive's Wayback Machine](https://web.archive.org/web/*/http://physnet.uni-oldenburg.de/oai/).
|
|
|
|
It was then modified in 2011 by [Jianfeng Li](mailto:jianfeng.li@adelaide.edu.au) at [University of Adelaide](https://www.adelaide.edu.au/) for [The Plant Accelerator](https://www.plantphenomics.org.au/). The modified version can be found in the [Google Code Archive](https://code.google.com/archive/p/oai-pmh-2/).
|
|
|
|
In 2013 [Daniel Neis Araujo](mailto:danielneis@gmail.com) at [Federal University of Santa Catarina](https://en.ufsc.br/) modified the project again in order to integrate it with [Moodle](https://moodle.org/). His implementation can be found on [GitHub](https://github.com/danielneis/oai_pmh). In 2014 [Kazimierz Pietruszewski](mailto:antenna@antenna.io) provided some [further bugfixes](https://github.com/antennaio/oai_pmh).
|
|
|
|
The current implementation was derived from the latter in 2017 by [Sebastian Meyer](mailto:sebastian.meyer@opencultureconsutling.com) at [Open Culture Consulting](https://www.opencultureconsulting.com/) for the [German Literature Archive](https://www.dla-marbach.de/en/). It is a stand-alone version focused on easy deployment and file based record handling.
