Subject: Re: [wsrp] Extension Proposals for F2F


Rich,

Sorry for the delay.

Here are our slides. I will lead the discussion of Multi-Section and Rewritable URLs. Kevin, will lead exporting registration properties.

Also, do you want to send a new 4-day agenda?

Thanks,

Nate

Could you prepare both a 1 slide summary (for use in the overview/prioritization discussion) and a discussion-oriented slide set for each proposal?

To make sure I have a basic understanding:
1. We have had quite a bit of discussion in the past, effort is to press toward completion

2. Goal is a Consumer moving from using a test Producer to using the equivalent Production Producer. WSRP v2 now supports moving the customized portlets, but if there were customized registration properties, there is no in-protocol means for moving these.

3. How to use XHR with the WSRP protocol has been an interesting discussion in the past. Lets make sure we fully develop what can be done with the current protocol (i.e. primer section) before we launch too far into extension ideas. Also, I will try and bring a summary of what is happening in the OpenAjax discussions so that our discussions can hopefully move toward leveraging their efforts as well.

Subject: [wsrp] Extension Proposals for F2F





I would like to discuss the following proposals:
1.        Finish the Multiphase Render proposal (HEAD section markup)
2.        Export Registration Properties - Allow a complete propagation of a producer.
  • Currently it is not possible to recreate a producer's registration on a different producer
  • Use case - Propagate a producer from staging to production
    • Staging Producer Setup
      • Register with a staging producer, with registration properties
      • Configure some portlets
      • Export from Staging
        • Export the the Registration Properties
        • Export the configured portlets
        • Import to Production
          • Register the producer, using the exported properties
          • Import the portlets
          3.        Make WSRP portlets more XMLHttpRequest (Ajax) friendly
          • This is currently more of a discussion point than a set of specific extensions
          • We have found issues with the following:
            • WSRP URLs are not rewritable
              • resource URLs
                • resource-id
                • wsrp-url
                • both
                • Perform Blocking Interaction
                • There is no way to tell the consumer to not send other markup (other portlets and page markup)
                • There is no way for the consumer to tell the producer this is an XHR request
                  • May require different handling by the producer and/or portlet
                  • There is no way for the producer to determine if multiple requests are part of a single client-consumer request
                  • What to do when there's IPC - Should other portlets' markup be processed
                    • Events
                    • Shared Parameters
                    • Use Cases:
                    1.        Simple Type Ahead (no portlet state required)
                    • The user starts type and matching words automatically appear in the text box
                      • E.g. Type "Co" and "Colorado" is entered for you
                      • The portlet sends a XHR to a resource URL
                        • Via the wsrp-url
                        • A GET parameter is tacked on to the URL
                        • The response is XML or JSON which the client-script process and places in the text box
                        2.        Type ahead based on a portlet's navigational state
                        • Type "Ha" and "Hamburger" appear in box (based on a previously entered value)
                        • The portlet sends a XHR to a resource URL
                          •  Via resource id
                          • A Get parameter is tacked on to the URL
                          • The response is XML or JSON which the client-script process and places in the text box
                          3.        Wizard Style Forms
                          • The user enters form values and presses "Next", the next page of the wizard appears
                          • The portlet sends a XHR to a performBlockingInteraction URL
                            • Parameters may be
                              • GET parameters tacked on the URL
                              • POST parameters in the stream
                              • The portlet saves its navigational state to include the new parameters and its place in the form
                              • The response is HTML which the client uses DOM manipulation to update the page
                                • div.innerHTML = request.responseText
                                • On a page refresh the portlet will return the HTML (via getMarkup) with user on the same page  and previously submitted values are accounted for
                                4.        Table Manipulation
                                • The user adds rows to a table, the page keeps track of the: sum, user average and company average
                                  • The user enters a number and presses "Add"
                                  • The table updates displaying a row for the new number and updates the sum and averages
                                  • A parameter may be
                                    • a GET parameter tacked on the URL
                                    • a POST parameter in the stream
                                    • The portlet saves its navigational state to include the value
                                    • The portlet calculates the sum and averages and returns their values as JSON or XML
                                    • The response is JSON or XML which the client uses DOM manipulation to update
                                      • data = "eval("("" + request.responseText + ")")
                                        sumNode.innerHTML = "<b>" + data.sum + "</b>"
                                        userAvgNode.innerHTML = "<b>" + data.userAvg + "</b>"
                                        companyAvgNode.innerHTML = "<b>" + data.companyAvg + "</b>"
                                      • On a page refresh the portlet will return the HTML (via getMarkup) with the user's data and the current sums and averages
