Arctic Sea

Description

52°North's backbone for OGC services, Clients and Middleware

A framework for developing OGC services, clients and middleware sharing concepts for encoding and decoding of different formats and encodings, workflows and configuration.

Arctic Sea is a stack of projects that eases the development of OGC related services such as the 52°North implementation of the OGC SOS and WPS, as well as clients and middleware. It compromises the following modules.

Iceland

Iceland is a service framework that enables the development of OGC RPC (remote procedure call) based services. It features bindings for KVP, POX, SOAP, as well as JSON-based bindings. Iceland facilitates the rapid development of modular services that use Faroe for easy configuration and Svalbard for request parsing and response generation.

Svalbard

Svalbard consists of various decoders and encoders for OGC models (e.g. SensorML, O&M and SWE Common, service interfaces (like SOS and WPS) and a framework for developing these. This enables the creation of decoupled and reusable encoders and decoders for various encodings (e.g. XML, JSON or NetCDF). The object models used are found in 52°North Shetland and are shared across 52°North components.

Faroe

Faroe is a configuration API currently featuring a JSON and a SQLite backend. It enables the injection and automatic configuration of settings of various types in classes, including a Spring BeanPostprocessor.

Shetland

Shetland consists of classes for OGC models like SensorML, O&M and SWE Common and various service requests and responses. These are shared across different service implementations.

Jan Mayen

Jan Mayen contains various utility classes shared throughout Arctic Sea.

Bjørnøya (Bjornoya)

Bjørnøya contains various classes for [Quartz] scheduling shared across Arctic Sea. These include configurations to define the execution of jobs.

Key Technologies

• OGC Web Services
• OGC Web Processing Service (WPS)
• OGC Sensor Observation Service (SOS)
• OGC SWE Common
• OGC SensorML
• OGC Observation and Measurement (O&M)
• Spring
• Java
• XML

Benefits

• The middleware component provides a robust layer to easily create web services compliant to OGC standards.
• The configuration API enables harmonized management of service properties.
• Centralized XML encoding and decoding reduces increases stability.
