Repositories who's content isn't available

Currently only a subset of ROAR-registered repositories are compatible with the content tools provided. This can be down to the following problems:

No OAI interface registered

If the record doesn't have an OAI interface registered (or worse, the repository doesn't have an interface), it can't be harvested.

OAI interface is broken

Unfortunately OAI isn't bullet-proof and problems in the interface can prevent successful harvesting. The harvest record link may be able to provide more information.

No records in the analysed period

Some analyses are time-limited e.g. the activity metric is only for the previous 12 months. This is because these are metrics for current activity and not historical (even though the repository may have a lot of records).

Analysing File Formats

The PRESERV Profile has several caveats in addition to requiring a functioning OAI interface, see the PRESERV Profile page for a full discussion.
