Attrib classes

What are Attributes in OBS?

Users can create an attribute (Attrib) of specific type (AttribType) with a value (AttribValue) on projects/packages. Some attributes are used to store meta information, others to influence behavior of OBS workflows.

What does each class represent?

AttribAllowedValue - Defines the values that may be chosen for when creating an Attrib with a certain AttribType.

AttribDefaultValue - Defines the default value that may be chosen for an Attrib of a certain AttribType.

AttribIssue - A many-to-many join that relates Attribs to Issues.

AttribNamespace - A namespace grouping for AttribTypes.

AttribNamespaceModifiableBy - Defines who has access to modify AttribNamespaces.

AttribType - Defines the type of Attrib.

AttribTypeModifiableBy - Defines who has access to modify AttribTypes.

AttribValue - What the values of an Attrib are.
