Project Goal Deploy and scale infrastructure and services for software emulation, including distributed management, sharing, documentation/discovery, and access. 3
What is Emulation-as- a-Service? 4
5
Distributed Mgmt A network of distributed nodes, each ￮ contributing to the EaaSI service and the software development roadmap. 6
Sharing In-network sharing of software images ￮ and configured environments. Yale University Library will contribute ￮ at least 3000 pre-configured software applications running in configured environments. 7
Access Emulated CD-ROM environment ￮ sharing service Virtual Reading Rooms Service ￮ Scientific Software Portal ￮ API to automatically render objects in ￮ original software via emulation 8
Documentation/ Discovery Incorporating services developed by ￮ Wikidata for Digital Preservation Comprehensive, open, ￮ machine-readable documentation Defining profile for description of ￮ software and computer environments 9
Metadata for software and computing emulation 10

SOFTWARE An expression of a software application which provides a single coherent Word 2000 (version 9.0) VERSION presentation with a well defined functionality and behaviour. SOFTWARE Application and system software that is Word 2000 (version 9.0) available for installation/configuration OBJECT from the NSRL collection in an environment. OBJECT Files necessary for installation and/or Disk images of operation of a software application FILES installation media within a computing environment. EaaSI – Software Object – Components 19
