188.8.131.52.1 - The repository shall have unique identifiers.
SP URIs for individual files and events are consistently constructed in the following manner:
- The URI of the parent object and a hash generated from the current date/time are concatenated. PDF files are identified by adding “pdf_fulltext” after the parent object URI and then the current date\time hash. While XML files are identified by adding “xml_fulltext” after the parent object URI and then the current date/time hash. In this way, there should be no chance of collisions.
