Some considerations for determining the value of information:

Can the data be reproduced in the future if needed?
How much would it cost to reproduce the data?
How much money/time do users save by having easy access to the information?
How much value do users of the data generate?
Data has value beyond what it was originally generated/collected for.
Combining the data with other data can multiply the value of the data.

Most of these ideas are reflected in the two slide sets that I sent out

Hope to join you this afternoon.
