The Validator service includes two main steps to perform the aggregation and indexing of your datasource in OpenAIRE:
- Validation
- Registration
1st: Validate your datasource
Test the compatibility of your repository/journal or aggregator to the OpenAIRE guidelines.
2nd: Register your datasource
Register your literature repository, data repository, journal or aggregator in OpenAIRE.
- Select datasource
Select from the list, or enter the base OAI URL of the repository/journal.
The repository’s/journal’s published sets are exposed in a later stage and you may select one for the compatibility tests.
- Select guidelines
You may apply two types of compatibility tests on your repository:
- Content: specific to the content/format of the dc fields
- Usage: specific to the implementation of OAI-PMH
You may select from a predifined set of rules (OpenAIRE for Literature Repositories, OpenAIRE for Data Archives) or customize them according to your needs.
- Select parameters
You may define an upper limit on the number of records tested. This is highly recommended for first time users, or when re-checking after the implementation of automated changes.
Select one of the repository's/journal's exposed sets.
You may also group your results by a specific field. This is quite useful when validating an aggregator and you know in advance which is the field that distinguished among data sources.
- Finish
Finish the compatibility test and await the results by email.
