Umm frankly, I am not sure anything out there right now is going to work to bring OAI-PMH services to WordPressConsider these three resources for more info on OAI:

• Main Technical Ideas of OAI-PMH
• Specification for an OAI Static Repository and an OAI Static Repository Gateway
• OAI-PMH Metadata Exchange

. If it does then is it going to be able to use WordPress to advertise things or is it going to use WordPress to aggregate things? if the former then nothing out there ever let the admin user choose which fields were matched to which attributes, dynamically. But if it is also the former then why would anyone actually want this functionality? What is the Use Case? If one is using WordPress as a bibliography reference system like some libraries do, then this makes a lot of sense. However, there is another use case I would like to present. That is, the website which is about several or a single language. There are potentially two ways to conceptualize this:

1. If there were a website based on WordPress which was a dictionary website then the whole website might be considered a resource on a language. An example of this might be the use of SIL’s Webonary Plugin for WordPress and the Cherokee Language Project’s Dictionary.
2. If there were a website presenting materials on several languages and each page was a resource on a single language then that would be a different use case. This would be more like what the Survey of California and
   Other Indian Languages does or what the Central Institute of Indian Languages does.

I think there is a second question here too: why does one need OAI-PMH for wordpress… is it as a provider or as a consumer? If one needs a PHP app for OAI-PMH maybe they can use: https://github.com/caseyamcl/phpoaipmh
