    RWW Interaction & ACL Testing using cURL

    What?

    The Linked Data Platform (LDP) specification from the W3C outlines how HTTP interaction patterns can be used to facilitate loosely coupled Create, Read, Update (Write), and Delete ("CRUD") operations, at World Wide Web scale.

    Why?

    The "Write" dimension of the World Wide Web has been underutilized since the Web's inception.

    • Identity-Driven Access Control & Privileges over Protected Resources
    • Identity-Driven Webs of Trust

    How?

    Different File Usage

    1: PKCS 12 File Usage


    curl --cert {pkcs#12-file-name}:{pwd} --cert-type P12 -k -I {resource-url}

    2: Secure PEM File Usage


    curl --cert {cert-pem-file-name} --key {private-key-pem-file-name} -k -I {resource-url}

    LDP QA

    1: Basic Metadata Interrogation


    curl -X OPTIONS -IH "Accept: text/turtle" http://example.com/DAV/home/demo/Public/

    2: Basic Metadata and Content Interrogation


    curl -iH "Accept: text/turtle" http://example.com/DAV/home/demo/Public/

    3: INSERT via POST with Slug header


    curl -X POST -ik -H "Content-Type:text/turtle"  -E MyCertificate-ODS-QA.pem:1234  --data-binary @profile2.ttl -H "Slug: profile2.ttl" https://example.com/DAV/home/demo/Public/

    4: INSERT via POST without Slug header


    curl -X POST -ik -H "Content-Type:text/turtle"  -E MyCertificate-ODS-QA.pem:1234  --data-binary @profile2.ttl https://example.com/DAV/home/demo/Public/

    5: INSERT via Inline Data without Slug header


    curl -X POST -ik -H "Content-Type:text/turtle"  -E MyCertificate-ODS-QA.pem:1234  --data-binary "<> a foaf:Document" https://example.com/DAV/home/demo/Public/

    6: Collection (Folder) Creation

    • Local data in ldp_container.ttl

<>                   a  ldp:Container
                     ,  ldp:BasicContainer
 ;       dcterms:title  "Sample Folder" 
 ; dcterms:description  "Sample Folder created using LDP." 
.
