title: Collection of relations for use in schemas
description: |
  This schema mixin provides a collection of relations for use in other
  schemas. It can be imported directly into other linkml schemas, or any of its
  individual property definitions can be used by their URI as vocabulary
  components or definitions (e.g., `dlprops-mixin:name` identified by this
  [URI](`name`)).

  Slot names use the plural form whenever they are directly declared as
  "multivalued" in this schema, otherwise the singular form is used for
  the slot name. The `slot_uri` always uses the singular form.

  Every property declared here is mapped to standard/established vocabularies.

  The schema definition is available as

  - [LinkML YAML](../unreleased.yaml)
  - [LinkML YAML (static/resolved)](../unreleased.static.yaml)

        This is conceptually the same as an instance-level `broad_mappings`.
        It can make sense to use this slot (in addition) in order to enable
        straightforward type declarations for instances from a controlled,
        application specific vocabulary, while also keeping the ability to
        use `broad_mappings` for alignment with external vocabularies and
        applications.
