Cognite's core data model—**CogniteCore**—offers standardized building blocks for industrial data, forming the basis for more specialized models. It's available from the **`cdf_cdm`** [system space](/cdf/dm/dm_concepts/dm_system_schemas).
The core data model uses two methods to define properties: [core features](#core-features) and [core concepts](#core-concepts):
* The **core features** are sets of properties that are available for **many** concepts.
* The **core concepts** have properties that are specific to a **single** concept.
Each core feature and core concept comes with a matching [**container**](/cdf/dm/dm_concepts/dm_containers_views_datamodels#containers) and [**view**](/cdf/dm/dm_concepts/dm_containers_views_datamodels#views). The exceptions are stateless concepts, which only have a view and no container. The **containers** have efficient [indexes](/cdf/dm/dm_concepts/dm_containers_views_datamodels#indexes) and constraints and can be used at scale out-of-the-box. The **views** combine the properties of the core features and the core concepts.
The core data model can be **extended**, currently via [GraphQL](/cdf/dm/dm_guides/dm_extending_core_data_model). For example, Cognite's **industrial data models** extend the **core data model** to meet common, industry-specific needs.
## Access control
In addition to the `dataModelInstancesAcl` capabilities to read/write the instances, users of the core data model need the following capabilities:
* `dataModelsAcl.READ` to `cdf_cdm` to read the core data model schema.
* `dataModelsAcl.READ` to `cdf_extraction_extensions` to read properties set by Cognite extractors.
* `dataModelInstancesAcl.READ` to `cdf_cdm_units` to use units.
For more information, see [Control access to a graph](/cdf/dm/dm_concepts/dm_access_control).
