Business is the showstopper

Technical problems are easy People, skills, time, resources

Business processes are hard High level scepticism re “technology driven” approach We need an elevator pitch Challenging established systems – destroying empires Changing legal processes (eg data licensing) Governance

The Problem

Agency A installs technology X

X only supports restricted data formats Format directly reflects data model of stored data

“Big Mining” wants the same data theme from Agency A and Agency B over the same locality

This can currently only happen if: Agency B also uses software X; Agency B uses the same data model as Agency A, and; These two dependencies will always remain

The solution

Feature type catalogues Community data models (eg Geochemistry XMML) Mechanisms/tools with which to use the community data

model

Method of accessing these catalogues SEEGRID roadmap

All you need in your databases Translation path from your organisation’s data model into

the community data model

Each layer is data, not merely a view:

Business Drivers

Reduce time to market

Client always gets latest data

Client goes to one place for data from multiple data sources No need to know all of the different data sources’ locations,

access methods, formats, etc.

No need to manage other peoples’ data

Save “shop” staff time

Managing IP Acknowledgement of the data source

at the destination

Copyright and licensing Data is freely available We still need to know who is using it

Business process Workflow Data management

Governance

Feature type catalogues Who manages the business process?

Conformance Who defines the standards? How are they changed?

Repository management Who is responsible? What are the rules?

Community standards and support technologies Hosting of services and standards

What is the level of availability required? Defining an SLA?

Issues to discuss

“Big Mining” is now reliant on external 3rd parties for its information systems. How does it gain sufficient confidence in SEEGRID for that to happen? Is an SLA sufficient? With whom?

Who has governance responsibility for the various components after this demonstrator? Registries Feature Type Catalogues

More issues to discuss

Rights management – how big an issue is it for your organisation?

Acknowledgement of data source in derived products?

Chaining services how do we manage indemnity and liability?
