The caDSR REST (XML-HTTP) API and CDE Browser provide access to, and a means of linking to, caDSR metadata through a standard internet browser.
caDSR REST results are can be displayed HTML in either or XML format - XML and can be displayed in an internet browser or by means of an XSLT stylesheet. The caDSR 4.0 Technical Guide describes the caDSR REST (XML-HTTP) API and provides a catalog of the caDSR operations and search criteria. To switch formats simply change the URL in the address line from "getHTML" to "getXML.
A few simple examples in both XML and HTML of caDSR operations are provided below. The attached MS Word documents for the examples show sample results and the "http" statements used to produce the results, and provide information about how to interpret the results. See also the REST API FAQs.
