[Moims-dai] Notes on meeting with Vint Cerf

Yes, it is critical to clearly define the Information to be preserved which then defines the amount of semantics needed. Otherwise long term success is unlikely. As Bruce notes, different repositories may have different needs even for the same starting data. I believe this is also critical for the preservation of complex information such as a performance.

Cheers,
Don

This is not a "cop out."  It is a conscious decision to allow communities to develop the digital preservation repositories that best meet current and future (as it can be surmised) community needs as preservation and future use impact and shape those community needs.

One may guarantee access only to the raw data; the other may guanantee access to the data and to how it looked and sounded.  Both can be legitimate approaches depending on their users and their technical capabilities.
