Parameter

Description

<Target Format>

Result format (XML, JSON, HTML).  The Target Format is preceded with the prefix “Get” followed by the format (one of XML, JSON, HTML) concatenated as one word.  

Target Format=XML:  … /GetXML?query= …   will return Target in the form XML.

Target Format = JSON:  … /GetJSON?query= … will return Target in the form JSON.

Target Format = HTML: … /GetHTTP?query= … will return Target in the form HTML

<Target>

Result class name. Use a valid caDSR Class name.  (One of DataElement, Form, …)

 e.g.  … query=Form[ … ]  will return caDSR Form class information.

<Criteria>

The criteria class that identifies the association to be traversed when retrieving the target/result class.   The Criteria will constrain the target/result based on the associated id/id value pair or pairs provided in the braces [ … ].

Note: The Criteria can be nested within the braces [ … ]. If the Criteria=Target then a short hand can be used and the Criteria is assumed to be equal to Target (this is referred to as an Implicit Criteria).

Implicit Example: GetXML?query=DataElement[@publicId=62 ]  Return Data Element with Data Element Public Id=62 in XML format.

Nested and Implicit Example:  GetXML?query=Form[Protocol[@preferredName=C3D ADOPTER TEMPLATES],@publicId=2392775 ]

Returns Form with Protocol preferredName=C3D ADOPTER TEMPLATES AND Form publicId=2392775

<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 the “AND” operation for all id/id value pair parameters provided for the Criteria class identified.

e.g. [@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.

e.g. [@publicId=62,@version=6]
