%META:TOPICPARENT{name="VirtPubSubHub"}% ---+ Feed subscription via PubSubHub Protocol The following demonstrates how the PubSubHub (PSH) Protocol can be used to make push subscription to an Atom or RSS feed. Before performing any of these steps, read about the [[VirtPubSubHub][Virtuoso PubSubHub implementation]], and make sure <code>[[https://virtuoso.openlinksw.com/download/][pubsubhub_dav.vad]]</code> is installed. ---++ Example Steps 1 Initially we create a blog instance and do some posts. %BR%%BR%<img src="%ATTACHURLPATH%/step1.png" style="wikiautogen"/>%BR%%BR% 1 Next we subscribe using the PSH generic client subscription UI. Go to http://cname/psh/subscribe.html and enter for ex. the following values as per attached: %BR%%BR%<img src="%ATTACHURLPATH%/step2.png" style="wikiautogen"/>%BR%%BR% 1 If subscription succeeds, we should see a Success message; otherwise, a trace for the error. %BR%%BR%<img src="%ATTACHURLPATH%/step3.png" style="wikiautogen"/>%BR%%BR% 1 In Feed Manager UI, we register the feed in order to see its content. %BR%%BR%<img src="%ATTACHURLPATH%/step4.png" style="wikiautogen"/>%BR%%BR% 1 Then we add one new post to the blog: %BR%%BR%<img src="%ATTACHURLPATH%/step5.png" style="wikiautogen"/>%BR%%BR% 1 Using generic publish client UI, we tell PSH there are changes; if all publishing is done we should see success message. Go to http://cname/psh/publish.html and enter for ex. the following URL as per attached: %BR%%BR%<img src="%ATTACHURLPATH%/step6.png" style="wikiautogen"/>%BR%%BR% 1 We check the feed subscription using feed manager, which in our case is used to display the feed. Now we can see new post is pushed into the subscription. %BR%%BR%<img src="%ATTACHURLPATH%/step7.png" style="wikiautogen"/>%BR%%BR% ---++ Conclusion * ODS-Feed Manager has an option to subscribe to push notifications using PSH protocol. Thus when subscribing it could subscribe to Hub. To know that it should inspect feed to see &lt;link rel="hub" href="..." . For demo purposes, this has been divided into two separate steps. * If ODS-Weblog knows there is a hub configured, it can present a link by which the hub can be accessed for push subscription * ODS-Weblog changes to publish to hub automatically. Publishing is shown here as two separate steps for purposes of explanation of the protocol. ---++Related * [[VirtODSPubSubHub][Setting up PubSubHub in ODS]] * [[VirtPubSubHub][PubSubHubBub Demo Client Example]] * [[VirtPubSubHubACL][Setting Up PubSubHub to use WebID Protocol or IP based control lists]] * [[http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtSPARQLEndpointProtection][Safeguarding your Virtuoso-hosted SPARQL Endpoint]] * [[http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtTipsAndTricksGuideSPARQLEndpointProtection][SPARQL Endpoint Protection Methods Collection]] * [[http://docs.openlinksw.com/virtuoso/][Virtuoso documentation]] * [[http://docs.openlinksw.com/virtuoso/rdfsparql.html#rdfsupportedprotocolendpoint][SPARQL Service Endpoint]] * [[http://docs.openlinksw.com/virtuoso/rdfsparql.html#rdfsupportedprotocolendpointuri][Service Endpoint Security]] * [[http://docs.openlinksw.com/virtuoso/rdfsparql.html#sparqwebservicetbl][Managing a SPARQL Web Service Endpoint]] * [[http://docs.openlinksw.com/virtuoso/rdfsparql.html][SPARQL]] * [[http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtTipsAndTricksGuide][Virtuoso Tips and Tricks Collection]] * [[http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtSPARQLDET][SPARQL Endpoint DET Configuration Guide]] * [[http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtSPARQLSecurityWebID][WebID Protocol & SPARQL Endpoint ACLs Tutorial]] * [[http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtOAuthSPARQL][SPARQL OAuth Tutorial]] * [[http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtTipsAndTricksGuideSPARQLEndpoints][Securing SPARQL endpoints]] * [[OdsSPARQLAuth][SPARUL over SPARQL using the http://cname:port/sparql-auth endpoint]] * [[http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtAuthServerUI][Virtuoso Authentication Server UI]] * [[http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtSPARQLSSL][Manage a SPARQL-WebID based Endpoint]] * [[VirtODSSecurityWebID][WebID Protocol Support in OpenLink Data Spaces]]. * Manage ODS Datadspaces Objects WebID Access Control Lists (ACLs): * [[ODSBriefcaseWebID][ODS Briefcase WebID based ACL Guide]] * [[ODSBriefcaseWebIDPerson][Person Entity WebID based ACL Guide]] * [[ODSBriefcaseWebIDGroup][Group Entity WebID based ACL Guide]] * [[ODSBriefcaseWebIDPublic][Public WebID based ACL Guide]] * [[ODSFeedManagerWebIDACL][ODS Feed Manager WebID based ACL Guide]] * [[ODSFeedManagerWebIDACLPerson][Person Entity Specific ACL]] * [[ODSFeedManagerWebIDACLGroup][Group Entity Specific ACL]] * [[ODSFeedManagerWebIDACLPublic][Public Specific ACL for anyone with a WebID]] * [[ODSCalendarWebIDACL][ODS Calendar WebID based ACL Guide]] * [[ODSCalendarWebIDACLPerson][Person Entity Specific ACL]] * [[ODSCalendarWebIDACLGroup][Group Entity Specific ACL]] * [[ODSCalendarWebIDACLPublic][Public Specific ACL for anyone with a WebID]] * [[ODSBookmarksWebIDACL][ODS Bookmark Manager WebID based ACL Guide]] * [[ODSBookmarksWebIDACLPerson][Person Entity Specific ACL]] * [[ODSBookmarksWebIDACLGroup][Group Entity Specific ACL]] * [[ODSBookmarksWebIDACLPublic][Public Specific ACL for anyone with a WebID]] * [[ODSAddressBookWebIDACL][ODS Addressbook WebID based ACL Guide]] * [[ODSAddressBookWebIDACLPerson][Person Entity Specific ACL]] * [[ODSAddressBookWebIDACLGroup][Group Entity Specific ACL]] * [[ODSAddressBookWebIDACLPublic][Public Specific ACL for anyone with a WebID]] * [[ODSPkiSetup][Guide for Set up a X.509 certificate issuer and HTTPS listener and generate ODS user certificates]] * [[ODSSetupSSL][Configure Virtuoso+ODS instance as an X.509 Certificate Authority and HTTPS listener]] * [[http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtSetupSSL][Configure Virtuoso instance as an X.509 Certificate Authority and HTTPS listener]] * [[OdsKeyImport][CA Keys Import using Conductor]] * [[ODSGenerateX509Certificate][Generate an X.509 Certificate hosted WebID Guide]] * [[ODSGenerateWebIDX509CertOSKeystore][Generate an X.509 Certificate (with a WebID watermark) to be managed by host operating system keystore]] * [[ODSGenerateWebIDX509CertBrsKeystore][Generate an X.509 Certificate (with a WebID watermark) to be managed by a browser-based keystore]] * [[ODSWebIDIdP][Using Virtuoso's WebID Verification Proxy Service with a WebID-bearing X.509 certificate]] * [[ODSWebIDIdpProxy][Using Virtuoso's WebID Identity Provider (IdP) Proxy Service with an X.509 certificate]] * [[ODSBriefcaseWebIDShareFile][ODS Briefcase WebID Protocol Share File Guide]] * [[http://esw.w3.org/topic/foaf+ssl][WebID Protocol Specification]] * [[https://foaf.me/simpleLogin.php][Test WebID Protocol Certificate page]] * [[http://test.foafssl.org/cert/][WebID Protocol Certificate Generation page]]
