Greet Japan Late in day for talk on archiving – get right started
Hot topic and here to stay What is cloud computing
Software hosting - virtualization Abstracted – complexity reduced Pay for amount of service, trust service provider to deliver General definition – when it comes to a specific area such as archiving
What we are afraid of…
To what extent is this possible with existing models?
Chosen because it is the de facto standard for archival systems
Incompatabilities with cloud computing -Data management, archival storage -starts with SIP. Share platform, shouldn&t be necessary to wait for SIP -references to digital objects The oais model - What does cloud model look like their descriptive information and administrative data is handled by Data Management
Layered, SaaS, PaaS, IaaS… HaaS in the case of crowdsourcing Bottom to top
2- With a defined API and classes and properties, possible to exchange one service for another as long as they support 3- Sharing, different programs sharing and taking advantage of similar services in the same layer What would a layered cloud archive system look like? particular set of rules and specifications that a software program can follow to access and make use of the services and resources provided by another particular software program that implements that API
Simple 2 layered model. 2 systems taking using a shared cloud repository as a storage backend All well and good, but to offer preservation
So to provide this information, we have expanded on the simple model
More detail about information provided by each layer
place different OAIS Information types in the layers just described. Preservation Layer, lot of different information types needed to generate information package. Where from
Putting it all together.
Moving on from theory to practice – Application of the model
