For caDSR II, the URL has been updated slightly from the legacy caDSR but returns the data in the same format as legacy caDSR.
To invoke this interface for the caDSR II API interface, use a URL in the form outlined below.

https://cadsrapi.cancer.gov/invoke/caDSR/<Target Format>?query=<Target>[<Criteria>[@<ID>@<ID>=<ID_VALUE>, …]] |
For example:
...
In the above example, the Target Format is GetXML, the Target is DataElement, and the Implicit Criteria are @publicIdare @publicId=62,@version=6. In the Implicit Criteria, one ID one ID is publicID publicId and the corresponding Value is 62, while the other ID is version and the corresponding Value is 6.
The following table provides more details:
Parameter | Description |
---|---|
<Target Format> | Result format (XMLGetXML, JSONGetJSON, HTMLor GetHTML). The Target Format is preceded with Use the prefix “Get” Get followed by the format (one of XML, JSON, or HTML) concatenated as one word. :
|
<Target> | Result class name. Use a valid caDSR Class name, such as DataElement , Form, (full list TBD).or Form. For a full list, refer to the caDSR II Domain Class Browser: https://cadsrapi.cancer.gov/caDSR/domain/browser.dsp For example, use … query=Form[ … ] will to return caDSR Form class information. |
<Criteria> | The criteria class that identifies the association to be traversed when retrieving the target/result class. The The Criteria will constrain the target/result based on the associated id/id value ID and ID_VALUE pair or pairs provided that you provide in the braces square brackets [ … ]. Note: The Criteria can be nested within the braces You can nest Criteria in the square brackets [ … ]. If the Criteria =is the Target, then a short hand can be used and the Criteria is assumed you can use a shorthand and the system assumes the Criteria to be equal to the Target. (this is referred to as an This is considered Implicit Criteria.).
|
<ID> | Attribute of the Criteria class used to constrain the query. For more than one attribute, use a comma between each attribute. The query will perform performs the “AND” AND operation for all id/id value all ID and ID_VALUE pair parameters you have provided for the Criteria class identifiedclass you have identified.
For example, use [@publicId@publicId= …] combined with the ID_VALUE below will be used to identify the constraints for the result returned. |
<ID_VALUE> | A string identifying the qualified criteria class data to be used as a filter on the result set. 1 or more id-criteria pair may be used. For example, [@publicId=62,@version=6] |
Comparing the format of the legacy caDSR to the caDSR II format:

A caDSR II (new) example:

For example, use [@publicId=62,@version=6] to identify a qualified criterion for the class specified in <Target>. |
