- Ephemerality
The Commission has identified six key
challenges that must be engaged if we intend to build a robustcyberinfrastructure:
- The ephemeral nature of digital data
- The nature of humanities and social science data
- Copyright laws
- The conservative culture of scholarship
- Uncertainty about the future mechanisms, forms, and economics
of scholarly publishing and scholarly communication moregenerally
- Insufficient resources, will, and leadership to build
cyberinfrastructure for the humanities and social sciences
Ephemerality
The study of human cultures and creativity is
founded on access to the records of the past. Preserving andensuring the authenticity of the artifacts and records of the past
is one of the most valued functions of libraries, archives, andmuseums—and yet we have only begun to learn how to do these things
with the political, economic, social, and cultural record of ourincreasingly digital civilization.
For an overview of some of the preservation
issues and literature, see Daniel J. Cohen and Roy Rosenzweig,“Preserving Digital History,” in Digital History: A Guide to
Gathering, Preserving, and Presenting the Past on the Web(Philadelphia: University of Pennsylvania Press, 2005)

Digital
data are notoriously fragile, short-lived, and easy to manipulatewithout leaving obvious evidence of fraud. Therefore, such content
is best preserved in trustworthy repositories, without which therewill be critical breaks in the chain of evidence. Although sites
such as YouTube, Flickr, Facebook, and MySpace
have become popular for
hosting digital collections, they are not repositories that ensurelong-term access to the content. The rapid turnover in digital
hardware and software often leaves digital data marooned on mediaor in formats that can no longer be accessed and that are highly
susceptible to deterioration and loss. Preservation requires thescrupulous management of data from the moment it enters a
repository through the steps of validation, storage, migration, anddelivery to parties that have been authenticated and authorized to
receive it. These are complex technical procedures dependent onstandards and protocols that work quickly and reliably.
Preservation was once an obscure backroom operation of interestchiefly to conservators and archivists: it is now widely recognized
as one of the most important elements of a functional and enduringcyberinfrastructure.

In biology, a pathogen (Greek: πάθος pathos "suffering", "passion" and -γενής -genēs "producer of") in the oldest and broadest sense, is anything that can produce disease. A pathogen may also be referred to as an infectious agent, or simply a germ.
The term pathogen came into use in the 1880s.[1][2
