4. Why open standards? • Value of the network • Use each other's data in situ • Seamlessly integrate & link our information products • Avoid the need to centralise, so we can control our own data for security, Quality Control and updating World Leaders in WebMapping Services

5. Technical Overview • The OpenGIS Architecture • OpenGIS Webmapping Specifications • www.opengis.org World Leaders in WebMapping Services

6. The OpenGIS Architecture • From systems to services • ACORN Services (network addressable components) • Applications, Catalogs, Operators, Repositories, Network • Agreements (“standards”) • Protocols (HTML, XML, …) • Component interfaces (OGC) • Semantics (Metadata schemas, Controlled Vocabularies, Business rules, etc.) World Leaders in WebMapping Services

7. ACORN-services Repositories - Data storage and access. Catalogs and Brokers - Elements that find and access resources on a distributed network. Operator and Models - Processes that operate on information, also methods to describe these processes. Applications – Shared components such as viewers, editors, discovery clients and others.
