SDI Library
SDI Library is a java library designed to help developers interact with gCube SDI. It is the main entry point for developpers wanting to exploits client implementations towards the SDI subsystems (i.e. SDI-Service, GeoNetwork, GeoServer ). It offers static gCube-fw-clients that communicate with SDI-Service for the management of gCube SDI and common publication features. It also manages client implementation for third-parties SDI technologies, allowing for direct communication with these subsystems.

Design
Following diagram illustrate the relations between the various clients components in gcube-sdi-suite.
To external users, the main component of interest is sdi-library, built on top of the sdi-interface which contains common classes definition.
SDI Library exposes basic gCube clients towards [[[SDI-Service]]] REST interfaces.
SDI Library also exposes means to dynamically load and instantiate client implementations for specific SDI subsystems (e.g. GeoServer, GeoNetwork).
Philosophy
The library has been designed to maximize isolation of dependencies : common complex logic is supported on services and client implementations are discovered at runtime.
The main library sdi-ibrary offers ways to obtain specific client implementation based on :
- Information System Configuration : accessible third-parties services, configuration and version
- Available implementations at runtime
Static Clients
Static clients are directly defined in sdi-library, so no dynamic loading is needed. They are implemented as gCube-fw-clients towards [[[SDI Sevice]]] REST interfaces and cover most common use cases such as :
- Manage SDI configuration (instances, credentials, IS Resources)
- Manage Application Profiles
- Instantiate Dynamic clients
- Common basic publish logic
SDI Management
Instantiate specific client
SDI Management should be used to dynamically instantiate client implementations against runtime configuration. It deals with
