If you have many metadata records or records that frequently change:

- Use OAI-PMH
- Provide them preferrably as [CMDI](http://www.clarin.eu/cmdi) ([click here](http://www.clarin.eu/node/3014) for details about how to serve CMDI over OAI-PMH)
- If that is not possible provide them as [OLAC](http://linguistlist.org/olac/olac.html)
- Depending on the situation your endpoint has to be added to [the centre registry](https://centres.clarin.eu/oai_pmh) (in case of a registered CLARIN centre), or added manually to our harvester
  - In case of a CLARIN centre
    - if your centre has already been registered in the Centre Registry, [contact the Centre Registry administration via e-mail](https://centres.clarin.eu/contacting). Make sure to provide the name of your centre and the complete URL of the endpoint.
    - if your centre has not yet been registered in the Centre Registry, [fill in the Centre Registry registration form](https://centres.clarin.eu/contacting).

  - Otherwise
    - Send a mail to harvester@clarin.eu to notify us about your OAI-PMH access point

If you have only a few static records and setting up an OAI-PMH access point is not feasible:

- Submit your records to the [Language Resource Inventory](https://forum.clarin.eu/content/language-resource-inventory) (for data, corpora, lexica, web services, software, …)
- All the records in the LRT inventory will be automatically converted into CMDI records. Note that this process can take a while.

Data provided over OAI-PMH or via the LRT inventory will be made available and searchable via the [Virtual Language Observatory](http://www.clarin.eu/vlo).
