Statistics
Issues : 3 types
When harvesting your repository/document we encountered an error that we couldn't resolve. These errors need to be fixed in order to to harvest your repository/document.
We encountered an error but we were still able to harvest the repository/document. We strongly recommend that these issues are resolved as they may lead to incompatibility problems in the future.
This may not be a problem but it may be a clue for misconfiguration or future incompatibilities.

Dashboard benefits - Increased and simplified collaboration between
aggregators and content providers- Improved control of the content provider over the
harvested content- Reduction of scepticism and fear of sharing
content with other systems- Improvement of the harvesting process- Broadening of the open access content
discoverability and thus reuse of the open access content where permitted
Would you like to take a look?
Dashboard still in BETA but we welcome volunteer testers
