The Source Management Service enables data source management in the Production DDMS which is together with entity and property - is one of key attribute that defines time-series.

The Property Discovery Service features enables the user to query and scan through the catalog of the available set of properties using various search criteria.

The Entity Management Service provides a set of APIs that enables the user to register OSDU Storage records as entities in Production DDMS, put them into relationships (hierarchies) and discover existing entities based on search criteria. Entities are defined through a type like well, meter, valve or platform. Two entities can have multiple entity relationships of a different types. The entities can be retrieved from the system in graph format with upward or downward graph traversal.

The Structure Storage Core (or internal) Service enables entities and their relationships management.

The Structure Query Core (or internal) Service provides low level APIs for fetching entities and their relationships from Hierarchy Store.

The Domain Model Core (or internal) Service is a catalog representing the production domain. It has the information about supported entity types, associated properties with these entity types. A property contains information that describes the characteristics of a time-series, such as the unique property identifier (descriptor), data type, measurement, etc.

The Cache Job is an internal background cron job that caches available entity hierarchies and time-series stream mapping for further rapid access by other services.

This is the home project for the OSDU core services. It provides an overview of all of the core services and activities related to the development, deployment, and operations of the core services

Open Subsurface Data Universe will use this repository to maintain the open datasets used for testing and demonstrating the solution.
