4.2.4.1.5 System of identifiers is adequate now and in the future

The system of identifiers shall be adequate to fit the repository’s current and foreseeable future requirements such as numbers of objects.

The APTrust system of semantic identifiers is not strictly numeric and is therefore not limited by the number of objects ingested. This ensures that each AIP can be unambiguously found in the future, as the unique identifiers are based on bag names. See section 4.2.4 for a description of how semantic and internal identifiers are constructed.
