This glossary defines the key Sitecore Content Hub terms and concepts.

ActionComponents that perform a specific task. Manually triggered by a user from the UI, automatically run by a trigger or by the API.
AdministratorA Sitecore employee responsible for the upkeep, configuration, and reliable operation of Content Hub. Can edit or delete any system-owned entity. Customers cannot be administrators.
AgentComponent configured to perform a specific type of task.
AssetEntities in Content Hub such as images, videos, or text files.
BlockA basic project, a multi-stage project, or a stage.
Brief assetAn image, document, or other type of file that helps demonstrate the purpose of a specific content item or campaign. Brief assets are used for inspiration and are not usually included in the content.
CampaignAction plan to promote a product.
CollectionA set of assets grouped together. For example, a collection can group related assets based on an event or a product. Collections make it easy to share content with collaborators.
ContentElement of a campaign such as a blog post, a recipe, or an advertisement.
Domain modelDefines the domain parts of a system and how these parts are structured and linked together. In Content Hub, the domain model is a representation of the entity types stored in Sitecore DAM and how they are related to – and inherit information from – each other.
Content collectionA content collection brings together content items that have a common property or purpose. It enables you to create, manage, and share channel-specific content for easy reuse.
Data modelA structured representation of the Content Hub underlying database. The data model – also known as a schema – includes entity definitions such as assets, products, or projects.
DraftTemporary instance of an item that lets you make modifications without starting a new creation and approval process. For example, you can create a draft of a published recipe that you want to update. The original recipe stays available but is locked while you edit the draft. When your draft is ready, you send it through an approval workflow for the changes to be approved and merged into the published version, at which point the draft is deleted.
DRMDigital Rights Management. Access-control technologies used to restrict usage of copyrighted works.
EntityA set of data that belongs together (such as for a product, campaign, project, story, recipe, or asset). In general, an entity is anything that you can find and display when searching for content. For example, an entity can be a digital asset (file) that has been uploaded along with its metadata, or it can be a collection of related data. An entity from another system linked to Sitecore DAM is called a proxy entity. You use proxy entities in Content Hub like any other entity. However, they are read-only because master-data ownership for this type of entity belongs to the other system.
Entity definitionSet of metadata properties that define how an entity is structured. The definition includes both descriptive metadata properties and relations with other entities. You can also think of the entity definition as a content type definition or an entity-specific metadata schema.
Entity propertyAn editable detail about an entity (such as product number, benefit, campaign brief, or file name). Properties can be, for example, text, numbers, option lists, or dates. They can be multilingual and you can define as many properties as you need on an entity. You can also specify properties to a proxy entity that are not available in the source system.
FacetFacets organize content based on taxonomy values and let the user limit search results based on the selected facet. You can organize and group facets using super facets.
FilterFilters lets you limit the number of results in a search so you can find the content you need.
FragmentSimilar to an asset, except that the content is a text snippet rather than a media file. A fragment consists of a rich-text snippet and a title.
JobA background process.
Job (MRM)A space in which teams and departments can work together.
MembersThe properties and relations you assign to an entity definition.
Member groupsA collection of members.
MessageData transported between the sender and the receiver application. For example, a message can be a request to the system to process an asset.
Page componentA container that holds the actual content of a page.
PolicyA user group policy that consists of rules, conditions, and permissions. Policies are assigned to users, determining what they can see and do throughout Content Hub.
Portal assetAn asset created specifically for a portal page.
Portal pageA page from which you can access and interact with data such as entities, components, relations, and properties. Users must be given access to a portal page to see its content.
ProductEntities in Sitecore Product Content Management (PCM), each representing a single product.
ProjectMarketing plan in Sitecore Marketing Resource Management (MRM).
Public linkFree access link to an asset.
QueueList of messages waiting to be processed in sequential order.
RelationLink between two entities that lets you display data from the parent-child relationship on relevant detail pages. By creating relations between entities, you make each entity more detailed without duplicating data. For example, you might have a product that is available in several colors, a recipe that uses several products, or a campaign that contains a story along with associated files. In each case, there is a relation between the parent and the children entities.
RenditionA rendition is a specific version of an asset (for example, an image might have an original and a medium-sized rendition). A custom rendition is one that is created from the asset details page, either by clicking + Rendition in the Renditions section or by clicking Download > Custom download. A custom rendition is for a specific asset, unlike a rendition configured in a media processing flow, which applies to all assets or specific types of asset.
SchemaSee Data model.
Search (saved search)The result of a search in Content Hub, saved as an entity object.
Security modelThe conditions for securing user access to entity definitions.
Selection (saved selection)A selection of assets saved as an entity object.
State flowThe logic applied to the content creation process. This consists of a series of states, transitions, and actions that superusers can enable for any type of content.
SuperuserA user with special privileges to configure and maintain a Content Hub solution. Can edit or delete any non-system-owned entity.
Super facetSuper facets organize facets into groups.
System-ownedSettings, definitions, properties, or components that are default elements in Content Hub. Superusers cannot edit these default elements.
TaskAction performed by a user in a project.
Taxonomy relationThe relation between entities that allows for advanced metadata and security inheritance through their family tree.
Taxonomy definitionEntity definition that is searchable as a facet in advanced searches.
TemplatePre-defined structure and default values to help build the domain model.
TransformationProcessing operation that allows superusers to manage the configuration of preset asset renditions and apply them to renditions dynamically.
TriggerConditions that, when met, automatically execute a set of actions.
VariantStand-alone copy of an original item that has at least one different property. This variant is considered a sibling or a child of the original item. Variants can be used to adapt an item to different locales, for example.
VersionRevision of an original content item that remains associated with the original, essentially an instance of a content item that you can make changes to without affecting the original. The main difference between drafts and versions is that drafts always merge into the original and hence they disappear when you are satisfied with the changes you made, whereas versions are different instances of the same content item. The latest version is considered the master version, but you can revert to an earlier version if necessary.
WIP assetAssets that have a status of either Created, Under Review, or Rejected are classified as work in progress (WIP).
WorkerSpecialized application that processes messages from queues.
