    LDP in Virtuoso - Simple Curl Examples

    Simple curl examples showing Virtuoso's support for LDP (Linked Data Platform) Basic Containers.

    Changes to resources made through the LDP REST interface are mirrored in the Conductor WebDAV UI.

    Contents

    1: Basic container lookup (GET on an LDP-BC)

    Request - Basic container retrieval


    curl -iH "Accept: text/turtle, */*;q=0.1" -u {username}:{password} "http://ods-qa.openlinksw.com/DAV/home/imitko/ldp-test/"

    Response - Basic container retrieval

    Note: The container was created prior to these tests and so was not empty.
