To make this possible, we created a\nRevisioned Database framework that allows for us to create new multiuser\nediting systems without data synchronization between users having to be a\nmajor concern. In this talk, solutions we've tried are discussed, the basic\nlayout of our revision database shown, the Python layer which handles it\ntransparently for the programmer detailed, and how the Python layer is used in\npractice. All of this is focused on discussing what worked well and what\npitfalls we ran into during development.\n\n", "quality_notes": "", "copyright_text": "Creative Commons Attribution-NonCommercial-ShareAlike 3.0", "embed": "", "thumbnail_url": "", "duration": null, "video_ogv_length": 401294147, "video_ogv_url": "", "video_ogv_download_only": false, "video_mp4_length": null, "video_mp4_url": "", "video_mp4_download_only": false, "video_webm_length": null, "video_webm_url": null, "video_webm_download_only": false, "video_flv_length": null, "video_flv_url": null, "video_flv_download_only": false, "source_url": "", "whiteboard": "", "recorded": "2010-02-19", "added": "2012-02-23T04:20:00", "updated": "2014-04-08T20:28:28.193" }
