This is really hard
- Federated- Non-hierarchical- Diverse- Inclusive- Distributed- Coordinated- Collaborative- Flexible- Sustainable
Characteristics Challenges
Funding/requirementsmismatch
Constant change
Natural language handling, scientific semantics
Hardware stabilityThe ‘haves’ vs. the ‘have nots’
Inconsistent implementation of standards
Political change
Differing international
data policies
How do you search 16000 recordsand get something scientifically useful?
Yarmey – RDAP 2014
Communicating search to users
Scheduling
So now what?
• Keep our eyes on the prize • We need to talk to each other• Data are not easy• Even discovery• Data might well not be cheap• Metadata Metadata Metadata Metadata
