Frequently Asked Questions
The Cloud Information Model (CIM) is an open, standards-based data model and consortium aimed at making enterprise applications and data sources interoperable across cloud and on-premises systems. This FAQ expands on the original CIM FAQ with practical context for enterprise data architects, integration and ETL engineers, platform vendors, and open-source contributors. It preserves the original answers while adding depth on how the model works, how it is governed, and how to decide whether and how to adopt it.
Key Takeaways
- CIM is an open specification and consortium, not a commercial product; its purpose is a shared, application-agnostic data model that reduces the cost and fragility of point-to-point integrations.
- Governance sits with the Joint Development Foundation under the Linux Foundation, with a Steering Committee historically including AWS, Google, Genesys, and Salesforce.
- Membership has two tiers: a paid Steering Committee level and a free Contributor level; the model itself is open source.
- CIM is expressed in multiple standards formats so that organizations with different technology stacks can adopt it without abandoning existing tooling.
- The model is most valuable when treated as a canonical vocabulary and mapping target, layered on top of existing systems of record rather than replacing them.
- Contributors retain control of their own data and IP; IP generated inside a working group is owned by the CIM legal entity under each group’s policy.
What Is the Cloud Information Model?
The Cloud Information Model (CIM) is an open consortium formed to deliver a standards-based solution for connecting enterprise products. Its stated goal is to let organizations create seamless, tailored personal experiences across cloud-native applications.
In practice, CIM is a shared data model — a common vocabulary of entities, attributes, and relationships — that different applications can map to. Rather than each integration team inventing its own field mappings between, say, a CRM and a marketing platform, both sides map to the same canonical definitions. That is the core interoperability promise.
CIM facilitates interoperability in several concrete ways:
- Faster time to value — reusable mappings and shared semantics shorten each new integration project.
- Seamless, customized experiences across cloud-native applications, because systems agree on what a “customer,” “order,” or “product” actually is.
- A cross-system view of data, enabling analytics and operational workflows that span multiple applications.
- Reduced time to build and maintain integrations, since changes are made against a stable shared model rather than brittle pairwise contracts.
It helps to place CIM in the broader landscape of data interoperability efforts. Where schema-on-read approaches (common in data lakes) defer structure until query time, and where API-specific schemas (such as those described by OpenAPI) describe a single service, CIM describes a domain model that many services can share. It is closer in spirit to canonical modeling traditions like those behind industry data models and to semantic web vocabularies such as those published by the W3C, though CIM is deliberately pragmatic and enterprise-oriented rather than purely academic.
What Cloud Application Challenges Does CIM Address?
CIM is a modern, open specification intended to ease the pain of integrating data. It provides a defined standard to communicate easily between different data formats.
The underlying problems it targets are familiar to anyone who has built enterprise integrations:
- Semantic mismatch. Two systems both have a “customer” object, but one treats a billing account and a person as the same thing while the other separates them. Without a shared model, every integration re-litigates these definitions.
- N-squared integration growth. Connecting N applications pairwise can require on the order of N² distinct mappings. A shared canonical model collapses much of that into N mappings to one model.
- Vendor lock-in and churn. When integrations are written directly against a vendor’s proprietary schema, replacing that vendor means rewriting the integrations. Mapping to a neutral model reduces switching cost.
- Cross-domain analytics. A consistent model makes it feasible to join data across sales, service, marketing, and commerce domains without bespoke reconciliation logic in every report.
CIM does not eliminate the need for ETL/ELT tooling, message brokers, or API gateways. It sits above them as the semantic layer that those tools map to and from.
How CIM Is Expressed Across Standards Formats
CIM working groups developed the model with a standards-based approach and translated it into multiple standards formats. This approach enables businesses with varying technologies to adopt CIM, empowers contributors, and fosters growth for a larger CIM ecosystem.
The practical implication is that you are not forced into a single serialization or toolchain. A model expressed in more than one format can be consumed by:
- Schema and API tooling that expects JSON Schema or similar structural definitions.
- Graph and semantic tooling that works with RDF-style vocabularies and ontologies.
- Relational and warehouse tooling that wants DDL or entity-relationship definitions.
- Code generators that produce typed classes or data transfer objects for application developers.
When evaluating adoption, a useful decision criterion is to identify which of your existing tools can already ingest one of the published formats. If your integration platform can consume the model directly, you avoid building a translation layer just to get started.
Who Can Join, and How Is CIM Governed?
CIM welcomes any and all contributors. It is open sourced as part of the Joint Development Foundation, which operates under the Linux Foundation. The Linux Foundation is a well-known home for collaborative open-source projects and provides the legal and organizational scaffolding that lets competitors collaborate on shared infrastructure.
Governance and participation break down as follows:
- Steering Committee. Historically four companies have been represented on the Steering Committee: AWS, Google, Genesys, and Salesforce. The Steering Committee sets direction for the model.
- Working Groups. These produce the model and its translations into standards formats, operating under pre-defined policies.
- Contributors. Anyone can collaborate and contribute to the CIM Model through the “Get Involved” channel.
Who owns the output of CIM?
The community members retain full control over their own data and IP. The IP generated by CIM members while working within a CIM working group is owned by the CIM legal entity and managed according to each working group’s pre-defined policy. This separation — your data and pre-existing IP stay yours; jointly created model artifacts are held by the entity — is a common and important pattern in open standards bodies, and it is worth reading the specific working group policy before contributing.
Membership Fees and Levels
CIM currently has two membership levels.
| Level | Annual Cost | Requirements | What You Get |
|---|---|---|---|
| SteerCo | $50,000 | Your company must be a Linux Foundation member | Access to the Steering Committee |
| Contributor | Free | None | Participation as a contributor |
The Contributor level requires no payment. The SteerCo level carries a fee and a prerequisite Linux Foundation membership, reflecting the additional governance responsibility and influence it confers. For most integration and platform teams, the Contributor level is the natural starting point; organizations that want to shape the model’s roadmap should weigh the SteerCo commitment against that influence.
How to Decide Whether to Adopt CIM
Adoption is a modeling and governance decision as much as a technical one. Consider these criteria:
- Do you have recurring, cross-vendor integration work? If you integrate the same domains repeatedly across changing vendors, a canonical model pays off. If you have one stable integration, it may not.
- Can your tooling consume a published format? Check whether your ETL platform, API gateway, or graph store can ingest the model directly.
- Do you have a domain that CIM covers? CIM is oriented toward customer-centric enterprise domains (customer, product, order, and related concepts). Domains outside that scope may need extension.
- Who will own the mapping layer? Someone must maintain the mappings between your systems of record and the canonical model. Treat this as a durable responsibility, not a one-time task.
- What is your exit strategy? Because CIM is neutral, mapping to it should make future vendor changes cheaper — verify that your mappings are genuinely decoupled from any single vendor’s schema.
A pragmatic adoption pattern is to start with one high-value domain, map two or three systems to it, and measure whether the shared vocabulary actually reduced integration effort before expanding.
Practical Guidance for Contributors and Integrators
For those getting involved, a few habits make the work more effective:
- Read the working group policy first. Understand IP ownership and contribution terms before you write anything.
- Model for reuse, not for one integration. A canonical entity should reflect the domain, not the quirks of a single source system.
- Document mappings explicitly. Keep a versioned record of how each source system maps to the model so changes are traceable.
- Prefer extension over mutation. If your domain needs something the model lacks, extend it in a way that does not break existing consumers.
- Engage upstream. Contributing improvements back to the model benefits everyone and reduces the maintenance burden of private forks.
Frequently Asked Questions
What is the Cloud Information Model in one sentence?
The Cloud Information Model is an open consortium and shared data model, governed under the Joint Development Foundation within the Linux Foundation, that gives enterprise applications a common, application-agnostic vocabulary so they can interoperate across cloud and on-premises systems.
Is CIM free to use and join?
Yes. The Contributor membership level is free and requires no payment, and the model is open sourced. The paid SteerCo level, which grants access to the Steering Committee, costs $50,000 annually and requires your company to be a Linux Foundation member.
Who is on the CIM Steering Committee?
Four companies are currently represented on the Steering Committee: AWS, Google, Genesys, and Salesforce. The Steering Committee guides the direction of the model while working groups produce the artifacts.
Who owns the intellectual property produced by CIM?
Community members retain full control over their own data and IP. IP generated by CIM members while working within a working group is owned by the CIM legal entity and managed according to that working group’s pre-defined policy.
How does CIM relate to other interoperability standards?
CIM complements rather than replaces API description formats, message schemas, and semantic vocabularies. It provides the shared domain model that those formats and tools can map to, similar in intent to canonical industry data models but focused on customer-centric cloud application domains.
How can I get involved with CIM?
Anyone can collaborate and contribute to the CIM Model through the “Get Involved” channel. A sensible first step is to review the working group policies, then start with a single domain and map a small number of systems to validate the approach.
