Crawling an OAI archive requires two connectors working together:
  • The identifiers crawling connector takes into account the given list of OAI sets to crawl, sorts identifier, and so on. It produces a clean list of OAI identifiers to be crawled.
  • The records crawling connector takes into account the set of identifiers produced by the identifiers crawling connector and crawls the meta-data information.
