Simple OAI-PMH 2.0 Data Provider
+================================
-Overview
+This is a stand-alone and easy to install data provider for the [Open Archives Initiative's Protocol for Metadata Harvesting (OAI-PMH)](http://openarchives.org/pmh/) written in [PHP](http://php.net/). It serves records in any metadata format from a directory of XML files using the filename as identifier and the filemtime as datestamp. Resumption tokens are managed using files. Multiple metadata formats and sets are currently not supported.
-This project is derived from the original work of Jianfeng Li
-from "The Plant Accelerator" for the "University of Adelaide".
+Just put the records as XML files in the data directory, adjust a few configuration settings and you are ready to go!
-In the original docs (you can see them on git log),
-Jianfeng Li he was inspired by PHP OAI Data Provider developed
-by Heinrich Stamerjohanns at University of Oldenburg.
-His implementation is at http://physnet.uni-oldenburg.de/oai/.
+Installation
+------------
-Almost all the code was rewritten in my attempt to understand
-both the OAI-PMH protocol and the original code itself.
+1. Deploy all the files to a webserver.
-The code changed so much that i removed the original documentation.
+2. Put the records into the data/ directory (or create a symlink named "data" pointing to your records). Each record has to be a separate XML file with its identifier as filename (i.e. 12345678.xml).
-There is some unit tests that were written based on the official
-protocol documentation at http://www.openarchives.org/OAI/openarchivesprotocol.html#ErrorConditions
-and also on the Open Archives Initiative - Repository Explorer at http://re.cs.uct.ac.za/
+3. Edit oai2config.php and adjust the settings according to your preferences.
-This version of the server relies on callbacks to get the needed data
-to generate the XML responses. The file oai2.php is a sample server
-instantiation to allow unit tests (OAI2ServerTest.php) to be run by
-PHP Unit. It has "hard-coded" data to pass the tests and validates
-that the server correctly reads correctly-formatted data.
-It is your responsibility to provide callbacks that provides
-correctly formatted data in all cases.
+4. Congratulations! Now you are running an OAI-PMH 2.0 compatible data provider.
-Tokens are managed using files.
+History
+-------
-XML Responses are created using the DOMDocument PHP interfaces.
+This project was originally initiated in 2002 by [Heinrich Stamerjohanns](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](jianfeng.li@adelaide.edu.au) of the [University of Adelaide](http://www.adelaide.edu.au/) for [The Plant Accelerator](http://www.plantaccelerator.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](danielneis@gmail.com) of the [Federal University of Santa Catarina](http://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).
+
+The current implementation was derived from the latter in 2017 by [Sebastian Meyer](sebastian.meyer@opencultureconsutling.com) of [Open Culture Consulting](https://www.opencultureconsulting.com/) for the [German Literature Archive](http://www.dla-marbach.de/en/).
