Appendix F: MetaArchive Microservices (open access)

Appendix F: MetaArchive Microservices

This is an appendix to the MetaArchive Final Report. The purpose of this document is to explain the PREMIS Event microservice as prototyped for the MetaArchive Cooperative, primarily from a developer's standpoint. The document will attempt to explain the purpose of the microservice, the underlying principles on which it operates, and a practical example of its usage. The MetaArchive has installed all of the components needed to deploy this microservice and looks forward to opportunities to experiment with practical implementations in future development projects.

Appendix B: MetaArchive-SRB Transfer (open access)

Appendix B: MetaArchive-SRB Transfer

This is an appendix to the MetaArchive Final Report. This appendix document is a report on the status of a two-phase transfer test being carried out between the MetaArchive Cooperative and Chronopolis. These tests aim to demonstrate a proof-of-concept that the MetaArchive network may use Chronopolis's data grid preservation service as an exit strategy in the event that either MetaArchive or LOCKSS becomes unsustainable in the future.

Appendix C: MetaArchive-iRODS Transfer Prep (open access)

Appendix C: MetaArchive-iRODS Transfer Prep

This is an appendix to the MetaArchive Final Report. This appendix document describes the preparation of archival units residing on a LOCKSS file system that have been designated for packaging and exchange with a non-LOCKSS-based preservation environment-in this case an iRODS grid-based environment.

Appendix D: LOCKSSBAGGER Tool (open access)

Appendix D: LOCKSSBAGGER Tool

This is an appendix to the MetaArchive Final Report. This appendix document describes tools. These tools are designed to facilitate the transfer of data contained within a number of LOCKSS archival units and packaged into bags. The bags are then transferred to the iRODS grid. The user has the option of creating and sending filled bags, or holey bags. The primary tools are written in Python, and make use of the iRODS command line utilities for data transfer.

Appendix E: MetaArchive-iRODS Transfer (open access)

Appendix E: MetaArchive-iRODS Transfer

This is an appendix to the MetaArchive Final Report. This appendix document describes an automation process that involved the sending of a Folger Shakespeare Library collection (246 archival units measuring 1.3TB) hosted on a University of North Texas (UNT) LOCKSS cache to a storage resource hosted by Chronopolis at the San Diego Supercomputer Center (SDSC).

Post-hatching development of mitochondrial function, organ mass and metabolic rate in two ectotherms, the American alligator (Alligator mississippiensis) and the common snapping turtle (Chelydra serpentina) (open access)

Post-hatching development of mitochondrial function, organ mass and metabolic rate in two ectotherms, the American alligator (Alligator mississippiensis) and the common snapping turtle (Chelydra serpentina)

This article investigates the metabolism, growth and muscle mitochondrial function in hatchlings of a turtle and a crocodilian, two ectotherms that never develop endothermy.
