Apache Jena Synchronization

An Apache Jena synchronization sends a published Spatial Knowledge Graph to a Jena triple store. Each run updates the data in the external system, rather than deleting and replacing the whole Jena database.

1. Go to the Settings page. Find the External System Synchronizations section.

   
2. Click Register Synchronization to open the Synchronization Configurations page.

   
3. Click Create to open the Synchronization Configuration form, and fill it out:

   

   Field name

   Description

   Required?

   Label

   The label of the synchronization profile.

   Yes

   Organization

   The organization the user belongs to. A synchronization profile will only be available to data and users within this organization.

   Yes

   External System

   The registered external system configuration that will be used to configure this synchronization. This must be registered before creating a synchronization.

   See Register an External System

   Yes

   Spatial Knowledge Graph

   The published spatial knowledge graphs from the system. The published graph that is selected will be used for pushing data to the external system.

   See Spatial Knowledge Graphs (SKG)

   Yes

   Namespace

   The base URI that begins the identifier of every resource in the published graph (e.g., https://data.example.gov/gpr/). This is the root descriptor of all the graph data. Use a domain your organization controls, and avoid changing it after publishing, since that changes every identifier.

   Yes

   Graph

   The name of the graph in the triple store that this synchronization populates. Named graphs keep each published SKG separate, so it can be queried, updated, or removed on its own.

   Yes

4. Click Submit to save the configuration.

   
5. Click View next to the configuration.

6. Click Run now to push the selected SKG to Jena. Its progress appears under Jobs.
