The Chronopolis project system has two sets of software which interact with each other in order to provide bit-level preservation. The first set, ChronCore, is a set of services which distribute data throughout the Chronopolis Network, which are network. These services are named Intake, Ingest, and Replication. The second software employed by the Chronopolis network is the Audit Control Environment (ACE) which continually audits data in Chronopolis to ensure the integrity of both the checksums and files. ACE consists of both an Audit Manager (ACE-AM) which runs locally and an Integrity Management Service (ACE-IMS) which is a web service currently hosted by UMIACS.
In addition to the software used for distributing data through the network, there are additional services for tertiary tasks:
- Repair - automates the workflow for correcting file errors within the Chronopolis Network
- Restore - automates the workflow for returning data back to a Depositor
