OAIS Catalog Services

OAIS Catalog Services are a set of facultative REGARDS services that allows to create a data source of products with metadata recommended by the CCSDS.

info

This data source is recommended for long-term archive catalog

To allow administrators to manage OAIS products, you need to use these microservices :

  • rs-ingest : Manage OAIS formated products data source
  • rs-storage : Manage files references and stored files
  • Optional rs-notifier : Highly configurable notification system. Can be used to inform external and internal components when an OAIS product is created or deleted.

Thanks to rs-ingest microservice, administrator can manage a new data source with OAIS formated products. To learn more about rs-ingest microservice see Ingest architecture.

This data source can be used as one of the data sources crawled by the data management service thanks to DataManagement OAIS Data Source Plugin.

To create products on the OAIS catalog, you can use these microservices :

  • Optional rs-data-provider : Scan files on file system and send OAIS Submission Information Package requests to OAIS catalog (rs-ingest).
  • Optional rs-lta-manager : Long term Archive system. Simplified interface to add products into the OAIS catalog (rs-ingest). Requires rs-worker-manager microservice.
  • Optional rs-worker-manager : Manager to handle regards workers. To use rs-lta-manager, worker manager is mandatory with a worker that receives simplified products format and send Submission Information Package requests to OAIS catalog (rs-ingest).

Populate using Ingest API​

The diagram below explains how to fulfill the OAIS products data source directly using rs-ingest :

This design uses:

info

This design is easy to start, but you should consider the usage of the LTA Manager and Worker as these services simplifies the interface to add products into the OAIS catalog.

Populate through DataProvider​

The diagram below explains how the rs-data-provider scan files on file system and send OAIS Submission Information Package requests to OAIS catalog

This design uses:

info

DataProvider is a no-code solution that scans the file system to add products to the OAIS catalog.

Populate through LTA Manager and Worker​

The diagram below explains the microservices interaction to fulfill the OAIS products data source with LTA Manager microservice and a Worker to create the SIP request.

Populate using another REGARDS GeoJSON catalog​

The diagram below explains how to populate the OAIS catalog using another GeoJSON REGARDS catalog.
