but, not my area

“allow it to be...incorporated digitally

in the collection”

“allow it to be...

traditional approach:

catalog recordsexhibit sites

cost of integrating everything

is high

cost of updating everything

is high

cost ofconsistent web strategies

is low

for example

Linked Data

use URIs as names for thingsuse HTTP URIs
