Domain data management service concepts

Domain Data Management Service (DDMS) – is a platform component that extends OSDU® core data platform with domain specific model and optimizations. DDMS is a mechanism of a platform extension that:

• delivers optimized handling of data for each (non-overlapping) "domain."
• pertains to a single vertical discipline or business area, for example, Petrophysics, Geophysics, Seismic
• serves a functional aspect of one or more vertical disciplines or business areas, for example, Earth Model
• delivers high performance capabilities not supported by OSDU® generic normal APIs.
• helps achieve the extension of OSDU® scope to new business areas.
• may be developed in a distributed manner with separate resources/sponsors.

OSDU® Technical Standard defines the following types of OSDU® application types:

Application Type	Description
OSDU®™ Embedded Applications	An application developed and managed within the OSDU® Open-Source community that is built on and deployed as part of the OSDU® Data Platform distribution.
ISV Extension Applications	An application, developed and managed in the marketplace that is NOT part of THE OSDU® Data Platform distributions, and when selected is deployed within the OSDU® Data Platform as add-ons
ISV third Party Applications	An application, developed and managed in the marketplace that integrates with the OSDU® Data Platform, and runs outside the OSDU® Data Platform

Characteristics	Embedded	Extension	Third Party

Who did we build this for?

IT Developers build systems to connect data to domain applications (internal and external – for example, Petrel) which enables data managers to deliver projects to geoscientists. The DDMS suite on Azure Data Manager for Energy helps automate these workflows and eliminates time spent managing updates.

Geoscientists use domain applications for key Exploration and Production workflows such as Seismic interpretation and Well tie analysis. While these users won't directly interact with the DDMS, their expectations for data performance and accessibility will drive requirements for the DDMS in the Foundation Tier. Azure will enable geoscientists to stream cross domain data instantly in OSDU® compatible applications (for example, Petrel) connected to Azure Data Manager for Energy.

Data managers spend a significant number of time fulfilling requests for data retrieval and delivery. The Seismic, Wellbore, and Petrel Data Services enable them to discover and manage data in one place while tracking version changes as derivatives are created.

Platform landscape

Azure Data Manager for Energy is an OSDU® compatible product, meaning that its landscape and release model are dependent on OSDU®.

Currently, OSDU® certification and release process are not fully defined yet and this topic should be defined as a part of the Azure Data Manager for Energy Foundation Architecture.

OSDU® R3 M8 is the base for the scope of the Azure Data Manager for Energy Foundation Private – as a latest stable, tested version of the platform.

DDMS requirements

A DDMS meets the following requirements, further classified into capability, architectural, operational and openness/extensibility requirements:

#	Description	Business rationale	Principle
1	Data can be ingested with low friction	Need to seamlessly integrate with systems of record, to start with the industry standards	Capability
2	New data is available in workflows with minimal latency	Deliver new data in context of the end-user workflow – seamlessly and fast.	Capability
3	Domain data and services are highly usable	The business anticipates a large set of use-cases where domain data is used in various workflows. Need to make the consumption simple and efficient	Capability
4	Scalable performance for E&P workflows	E&P data has specific access requirements, way beyond standard cloud storage. Scalable E&P data requires E&P workflow experience and insights	Capability
5	Data is available for visual analytics and discovery (Viz/BI)	Deliver minimum set of visualization capabilities on the data	Capability
6	One source of truth for data	Drive towards reduction of duplication	Capability
7	Data is secured, and access governed	Securely stored and managed	Architectural
8	All data is preserved and immutable	Ability to associate data to milestones and have data/workflow traceable across the ecosystem	Architectural
9	Data is globally identifiable	No risk of overwriting or creating non-unique relationships between data and activities	Architectural
10	Data lineage is tracked	Required for auditability, re-creation of the workflow, and learning from work previously done	Architectural
11	Data is discoverable	Possible to find and consume back ingested data	Architectural
12	Provisioning	Efficient provisioning of the DDMS and auto integration with the Data Ecosystem	Operational
13	Business Continuity	Deliver on industry expectation for business continuity (RPO, RTO, SLA)	Operational
14	Cost	Cost efficient delivery of data	Operational
15	Auditability	Deliver required forensics to support cyber security incident investigations	Operational
16	Accessibility	Deliver technology	Operational
17	Domain-Centric Data APIs		Openness and Extensibility
18	Workflow composability and customizations		Openness and Extensibility
19	Data-Centric Extensibility		Openness and Extensibility
