{urn}/metadata/{modelGuid}/properties:query
Queries the objects in the Model View (Viewable) specified by the modelGuid
URI parameter and returns the specified properties in a paginated list. You can limit the number of objects to be queried by specifying a filter using the query
attribute in the request body.
Note: A design file must be translated to SVF or SVF2 before you can query object properties.
Before you call this operation:
- Use the List Model Views operation to obtain the list of Model Views in the source design.
- Pick the ID of the Model View you want to query and specify that ID as the value for the
modelGuid
URI parameter.

modelGuid string | The ID of the Model View (Viewable) that contains the objects you want to fetch properties for. |
Request
Body Structure
pagination object | Specifies how to split the response into multiple pages, and return the response one page at a time. |
limit int | The maximum number of properties to return in a single page. Use this attribute with the offset attribute to split the properties into multiple pages. To fetch the first page, specify offset =0 (do not skip any properties). To fetch the second page, specify offset = value of limit you specified for the first page. So, the server skips the search results returned on the first page. In general, offset = previous_offset + previous_limit . This attribute is 20 by default. The minimum value is 1 and the maximum is 1000. |
offset int | The number of properties to skip. Use this attribute with the limit attribute to split the properties into multiple pages. To fetch the first page, specify offset =0 (do not skip any properties). To fetch the second page, specify offset = value of limit you specified for the first page. So, the server skips the properties returned on the first page. In general, offset = previous_offset + previous_limit . This attribute is 0 by default. The minimum value is 0. |
query* object | Contains the parameters to pass to the query backend. Specifies what objects to query. |
oneOf | |
$in array | Returns only the objects with their objectid or externalId attribute exactly matching one of the values specified in the array.
The first element of the array contains the name of the attribute to match ( For example, if you specify an array as: |
$prefix array, string | Returns only the objects with their name attribute beginning with the specified string.
The first element of the array contains the name of the attribute to match ( |
$eq array | Returns only the objects where the value of the specified attribute (name attribute or any numerical property) is exactly equal to the specified value.
The first element of the array contains the name of the attribute. This can be the For example, if you specify an array as: Note: We recommend that you use |
$between array | Returns only the objects where the value of the specified numerical property lies between the specified values.
The first element of the array contains the name of the property. The next two elements specify the values that the property must lie between. The array can only be three elements long. For example, if you specify an array as: Note: The Model Derivative service converts numeric values from their native units to metric base units for comparison. So, you must specify the values to compare in metric base units. For example, if the property you are comparing is a length measurement, you must specify the values in |
$le array | Returns only the objects where the value of the specified numerical property is less than or equal to the specified value.
The first element of the array contains the name of the property. The next element specifies the values that the property must be less than or equal to. The array can only be two elements long. For example, if you specify an array as: Note: The Model Derivative service converts numeric values from their native units to metric base units for comparison. So, the value to compare must be specified in metric base units. For example, if the property you are comparing is a length measurement, you must specify the value in |
$ge array | Returns only the objects where the value of the specified numerical property is greater than or equal to the specified value.
The first element of the array contains the name of the property. The next element specifies the values that the property must be greater than or equal to. The array can only be two elements long.

So, the value to compare must be specified in metric base units. For example, if the property you are comparing is a length measurement, you must specify the value in |
$contains array, string | Returns only the objects where the value of the specified property contains the words specified in a string.
The first element of the array contains the name of the property. The second element contains a string containing the words to match. The array can only be two elements long. For example, if you specify an array as: |
