Basic Usage

  • This feature helps share Journal/Documents/Mounted-Drives' entries across XOs, via the following two mechanisms ::


    • Peer-to-Peer mode
      • Sharing in this mode is possible, only when the server and client XO(s) are on the same networks. Thus, peer-to-peer sharing would work on
        • XOs connected to the same Access Point.
        • Adhoc-Network connections.


    • Via-School-Server mode
      • In this mode, an XO uploads an entry to the central School Server; from where the client XO(s) may download the entry.
      • This mode of sharing works as long as the School-Server is HTTP-pingable between the server and client XOs. Thus, this mode of sharing would work when
        • XOs are connected to the same Access Point (as long as school-server is pingable throughout).
        • XOs are connected to the different Access Points (as long as school-server is pingable throughout).
        • XOs are conencted to Adhoc-Network (as long as school-server is pingable throughout).




Credits

  • Plan Ceibal
    • For supporting this feature development.


  • Sascha Silbe silbe@activitycentral.com
    • Initial Proposal for the solution based on WebDAV.


  • Anish Mangal anish@activitycentral.com
    • Showed why simply accessing the webdav shares via "Browse" activity won't work.
    • The reason is that accessing Sugar-WebDAV shares via "Browse" (or in any browser), would show only the availability of files. But a Sugar-entry is more than just the (data) file; it is a combination of
      • Metadata-file
      • Data-file
      • Preview-file (optional)
    • Also, the current workflow conforms to the sugar look-and-feel too. (Thanks again Anish).


  • Ruben Rodriguez ruben@activitycentral.com
    • Feedback on the "peer-to-peer" mechanism; now when the user clicks "Access Share", the user is directly taken to the newly mounted remote-share view.

Example Workflow for Peer-To-Peer Mode

NOTES

    • An entry present in "Local Shares", is available to other peers, when the peer(s) mount this XO's shares.
    • Note that the entries present in "Local Shares", have nothing to do with the entries present in "School Server Shares".
    • In the following screenshots' example, "PEER 2" mounts the shares of "PEER 1"; and uses that to copy entries onto its own XO. Thus, the entry is copied from XO-of-PEER-1 to XO-of-PEER-2.



SCREENSHOTS

[PEER 1] "Journal" - View.

P11.png






[PEER 1] Detail view of the journal-entry. Note the preview presence.

P12.png






[PEER 1] Initial "Local Shares" View

P13.png






[PEER 1] Copy the journal entry to "Local Shares", to make it available for sharing to other peers.

P14.png






[PEER 1] "Local Shares" view, after copying the entry.

P15.png







[PEER 1] The detail view in "Local Shares". NOTE that the preview MUST be present, and it must be same as that of "Journal".

P16.png








[PEER 2] Initial "Journal" - View.

P20.png






[PEER 2] Neighborhood View.

P21.png






[PEER 2] Click on "Access Share" of the peer, whose shares need to be accessed.

P22.png






[PEER 2] The peer's shares are mounted.

P23.png






[PEER 2] Copy the entry to the journal.

P24.png







[PEER 2] Final "Journal" View.

P25.png






[PEER 2] Detail-view of the entry. Note that the preview is the same as was on the remote peer.

Example Workflow for Via-School-Server Mode

NOTES

    • An entry present in "School Server Shares", is available to all the XOs. There isn't any mounting or anything required as such.
    • Note that the entries present in "School Server Shares", have nothing to do with the entries present in "Local Shares".
    • In the following screenshots' example, an XO uploads an entry to the school-server, and then downloads the same. HOWEVER, NOTE THAT ANY XO WOULD BE ABLE TO DOWNLOAD THE ENTRY PRESENT ON THE SCHOOL-SERVER, AND NOT ONLY NECESSARILY THE UPLOADER.



SCREENSHOTS

[UPLOAD] Initially, no entries are present on the school-server.

HOW TO SETUP



  • VIA-SCHOOL-SERVER





TEST-CASES THAT NEED TO PASS

  • Inter-copying an entry between Journal/Documents/Mounted-Drives/Local-Shares/School-Server-Shares should behave in the same way. For eg, in the peer-to-peer mode, it was shown that the source-entry (on PEER-1) had a preview; the same was true when the entry finally arrived on PEER-2. In particular, the preview should "go along" as and when the entry goes, intra-XO or inter-XO.
  • Things should work fine, irrespective of the fact that whether the sharing is done via single-mode, or batch-mode.
