The following setting determines whether the AIP Ingester should create an EPerson (if necessary) when attempting to restore or ingest an Item whose Submitter cannot be located in the system. By default it is set to "false", as for AIPs the creation of EPeople (and Groups) is generally handled by the DSPACE-ROLES crosswalk (see #AIP Metadata Dissemination Configurations for more info on DSPACE-ROLES crosswalk.)

It is recommended to validate all AIPs on ingestion (when possible). But validation can be extremely slow, as each validation request first must download all referenced Schema documents from various locations on the web (sometimes as many as 10 schemas may be necessary to download in order to validate a single METS file). To make matters worse, the same schema will be re-downloaded each time it is used (i.e. it is not cached locally). So, if you are validating just 20 METS files which each reference 10 schemas, that results in 200 download requests.

In order to perform validations in a speedy fashion, you can pull down a local copy of all schemas. Validation will then use this local cache, which can sometimes increase the speed up to 10X10 x.

To use a local cache of XML schemas when validating, use the following settings in 'dspace.cfg'. The general format is:
