-h4. Filtering on subproperties
+h4(#subpropertyfilters). Filtering on subproperties
Some record type have an additional @properties@ attribute that allows recording and filtering on additional key-value pairs. To filter on a subproperty, the value in the @attribute@ position has the form @properties.user_property@. You may also use JSON-LD / RDF style URIs for property keys by enclosing them in @<...>@ for example @properties.<http://example.com/user_property>@. Alternately you may also provide a JSON-LD "@context" field, however at this time JSON-LD contexts are not interpreted by Arvados.
|_. Attribute|_. Type|_. Description|_. Notes|
|name|string|The name of the container_request.||
|description|string|The description of the container_request.||
-|properties|hash|Client-defined structured data that does not affect how the container is run.||
+|properties|hash|User-defined metadata that does not affect how the container is run. May be used in queries using "subproperty filters":{{site.baseurl}}/api/methods.html#subpropertyfilters||
|state|string|The allowed states are "Uncommitted", "Committed", and "Final".|Once a request is Committed, the only attributes that can be modified are priority, container_uuid, and container_count_max. A request in the "Final" state cannot have any of its functional parts modified (i.e., only name, description, and properties fields can be modified).|
|requesting_container_uuid|string|The uuid of the parent container that created this container_request, if any. Represents a process tree.|The priority of this container_request is inherited from the parent container, if the parent container is cancelled, this container_request will be cancelled as well.|
|container_uuid|string|The uuid of the container that satisfies this container_request. The system may return a preexisting Container that matches the container request criteria. See "Container reuse":#container_reuse for more details.|Container reuse is the default behavior, but may be disabled with @use_existing: false@ to always create a new container.|
|tail_uuid|string|The origin or actor in the description or action (may be null).|
|link_class|string|Type of link|
|name|string|Primary value of the link.|
-|properties|hash|Additional information, expressed as a key→value hash. Key: string. Value: string, number, array, or hash.|
