World Leaders in WebMapping Services5 Technical Overview The OpenGIS Architecture OpenGIS Webmapping Specifications

World Leaders in WebMapping Services6 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.)

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.
