+# Glossary
+
+## Record lifecycle
+
+#### Metadata {#metadata}
+:   Descriptive information about a record, such as title, authors, [resource type](#resource-type), and identifiers. Metadata can be edited after a record is published; files cannot.
+
+#### Resource type {#resource-type}
+:   The category describing the kind of content in a record, such as dataset, publication, software, or presentation.
+
+#### Deposit form {#deposit-form}
+:   The form used to create or edit a record by entering [metadata](#metadata), uploading files, and configuring access settings.
+
+#### Draft {#draft}
+:   A record that has been saved but not yet published. Drafts are only visible to the uploader and anyone explicitly granted access. They do not appear in search results.
+
+#### Published record {#published-record}
+:   A record that has been finalised and registered in the system. Once published, files can no longer be changed, but metadata can still be modified. A published record is not necessarily public — its visibility depends on the access settings configured.
+
+#### New version {#new-version}
+:   A [draft](#draft) created from a [published record](#published-record), used when files need to be modified or replaced. All versions remain accessible and are linked together in the record's version history.
+
+#### Embargo {#embargo}
+:   A time-based restriction applied to one or more files. Embargoed files are not accessible until the specified date, even if the record's metadata is public.
+
+## Visibility & access
+
+To learn more, see [Access & Share](deposit/access-share.md).
+
+#### Public {#public}
+:   A record or file that is visible to anyone, including unauthenticated users.
+
+#### Restricted {#restricted}
+:   A record or file that requires a CERN account or explicit permission to access. A restricted record may have public metadata while its files remain restricted.
+
+#### Access request {#access-request}
+:   A request submitted by a user to gain access to restricted files or record. The record owner receives a notification to approve or deny the request. Access requests can be enabled or disabled using the Share button.
+
+#### Shareable link {#shareable-link}
+:   A link that grants access to a [draft](#draft) or record to users who cannot log in to CDS. Shareable links can be generated using the Share button.
+
+## Identifiers
+
+#### DOI {#doi}
+:   A Digital Object Identifier — a persistent identifier when a record is published. CDS can register a DOI automatically, or you can provide an existing external DOI. See [what is a DOI?](https://www.doi.org/the-identifier/what-is-a-doi/) for a general introduction.
+
+#### Report number {#report-number}
+:   An alternative identifier for a record which tends to be used in research. It should not be treated as a unique identifier.
+
+## Community & roles
+
+To learn more, see [About communities](communities/communities.md).
+
+#### Community {#community}
+:   A space in which records are curated and managed by a specific group of users, typically representing an experiment, department, or project at CERN. A record must belong to at least one community and may belong to more than one.
+
+#### Curator {#curator}
+:   A community member with permission to review [submission requests](#submission-request), edit records that belong to the [community](#community), and manage the community's content.
+
+#### Inclusion request {#inclusion-request}
+:   A request to add an already [published record](#published-record) to an additional [community](#community). Since a record can belong to more than one community, an inclusion request allows it to be curated by another community without creating a new version.
+
+#### Submission request {#submission-request}
+:   A request to publish in a [community](#community). Submitting a record sends it to the community's [curators](#curator) for [review](#review).
+
+#### Review {#review}
+:   The process where a [curator](#curator) evaluates a [submission request](#submission-request) and determines whether it should be accepted into the community.
