Starting with CDM SDK release 1.7.1 the CdmStandardsAdapter is no longer requiring CDM Schema Store to provision foundational definitions required for CDM metadata parsing, as they are now bundled in the SDK binaries directly. The bundled definitions **do not** include CDM application schemas (e.g. [schemaDocuments/core]([url](https://github.com/microsoft/CDM/tree/master/schemaDocuments/core)), [schemaDocuments/FinancialServices]([url](https://github.com/microsoft/CDM/tree/master/schemaDocuments/FinancialServices))...), only the foundational definitions in the [schemaDocuments]([url](https://github.com/microsoft/CDM/tree/master/schemaDocuments)) root are included to reduce binary size. If you have a dependency to these additional schemas, please package them and reference them from your project.
The CDM Schema Store will be shut down by **end of March '24**, and any services still using the older CDM SDK releases may start failing due to unavailability of the store. If you are still using the SDK versions prior to 1.7.1, please upgrade **now**!
Do you use the Common Data Model SDK? If you do, please can you tell us which version(s) you use (C#/.NET, Java, Python, or TypeScript) by taking this [**short survey**](https://forms.office.com/r/hainr3a7rR).
The Common Data Model is a declarative specification, and definition of standard entities that represent commonly used concepts and activities across business and productivity applications, and is being extended to observational and analytical data as well. CDM provides well-defined, modular, and extensible business entities such as Account, Business Unit, Case, Contact, Lead, Opportunity, and Product, as well as interactions with vendors, workers, and customers, such as activities and service level agreements. Anyone can build on and extend CDM definitions to capture additional business-specific ideas.
The Common Data Model standard defines a common language for business entities covering, over time, the full range of business processes across sales, services, marketing, operations, finance, talent, and commerce and for the Customer, People, and Product entities at the core of a company's business processes. The goal of CDM is to enable data and application interoperability spanning multiple channels, service implementations, and vendors. CDM provides self-describing data (structurally and semantically), enabling applications to easily read and understand the data.
Maintaining forward and backward compatibility is a key goal of the CDM. Therefore, the CDM uses only additive versioning, which means any revision of the CDM following a "1.0" release will not:
