Owncloud 6 Brings Collaborative Open Document Format Editing to the Web 73

Posted by Unknown Lamer from the process-calculus-for-english-homework dept.
OwnCloud version six was released last week, and part of the release was a pretty major new feature: real-time collaborative editing of ODF documents (the format used by Libreoffice, Calligra, etc.). Although Etherpad has supported collaborating on simple text document for a while now, this is the first Free Software equivalent to Google Docs. From the article: "WebODF is a javascript library that lets you display ODF files in your browser. Think of it as PDF.js, but for ODF. You just throw a webodf.js script on your server, and do a couple of javascript calls to render an ODF file. It works completely client-side, no serverside ODF processing required. ... The collaborative server, included with OwnCloud Documents, lets users join a 'session', which is basically a document with a history of edit operations. Operations are small units of edits (think 'commits'). In a collaborative session, we use Operational Transformation techniques to make sure that operations fired by various clients will eventually result in a consistent state everywhere. When a new client joins an existing session, all earlier operations are played-back for it to reach the current state. Note that this editing is not turn-based; this is true inline collaborative editing where users can join a document and start editing straight away." As always, source is available.

      The server-side is a fairly trivial install (especially because they provide repos for every major distro), mostly just depending on PHP. You can store data/config in MySQL, postgreSQL, or SQLite (the default, but obviously not recommended for multiple users). The files themselves have for some time been saved in per-user folders, with a separate folder for past versions of files (by default all files are versioned). For the Documents app, it seems to store a copy of each file named with a UUID/hash in the "documents" folder for each user, the filename that you see it as being merely kept in the database.

        That seems too simplistic. Shared document editing has all the same issues as shared source code editing. Just saving old versions in their entirity isn't too helpful, especially when multiple people are editing. You need something at least as good as Wikipedia history diffs. (Git might be overkill.)

      The server side can be really simple. In a real-time collaboration scenario, there needs to be conflict resolution. The code for that is implemented in JavaScript as well and, in the case of ownCloud Documents, runs in the clients.

      Each change to the document is sent as a numbered operation to the server. If a change with the same number has already arrived, the latest changes are sent back to the client. The client then modifies/rebases the original change on top of the new changes and send the change again

      AbiCollab certainly precedes by many years. WebODF is newer and has two advantages of AbiCollab.net.

      First, WebODF runs just in a browser with no need to install it locally. It runs completely on a webpage. That's why it can by integrated into any web-based workflow. E.g. a user could generate a document by filling in a questionnaire and edit a document afterwards with WebODF.

      Second, there is no document conversion. A document that is loaded into LibreOffice, AbiWord, OpenOffice, or Microsoft Office, edited

  • I've been waiting for ODT editing to come to ownCloud for a while now so I could drop my last Google usage outside of search. I just wish there was a way to use it while turning off the collaborative stuff. Things seem to go wonky when you don't close a document properly sometimes.

  • I setup an older version at work to sync important files between laptops. Version wasn't that far behind. We had nothing but trouble with it. If clients didn't hit the network or Internet, sometimes the clients would just lose all their settings. And client setup was not trivial, so I had to be the one to do it. Also, it would sometimes create a huge number of dupe files, which were versioned in order to stop collisions.

    All in all, we ditched it for Goodsync. Not perfect, but it doesn't just one day up and lose all its settings for no apparent reason or create hundreds and hundreds of dupe files.

      A lot was fixed in 5 and it was easy to set up and use. The only hassle I've seen with the client software (which the users setup themselves without help), is sync issues of files vanishing on clients with clocks that are out by tens of minutes. The files are still available in the "previous versions" part of the web GUI but it's still very annoying behaviour.
      The linux client in 5 also didn't handle links to different filesystems from the sync directory.

I started using 6 when it was in beta and I only had one stupid deadlock issue which there was no way of fixing easily and one quota issue (it appears to be broken at the moment, even when my 40GB quota was less than half used, it was reporting full). Allegedly fixed but I just removed my quotas.

    I just set it up on a spare server and had a quick play with an odt version of a NIH grant (US National Institutes of Health) I'm collaborating on at the moment. Not too shabby - unlike google docs it doesn't completely bork the page formatting and the collection of styles we use to keep it in line with the (typographically absurd) requirements of the NIH (oh, SF424, how I hate thee). Which is a big deal, because most of the sections required in an NIH grant have strict page limits (and required fonts, font sizes, line spacing, and margin limits), and getting right to those page limits without going over is important. So when you've finished collaborating and are ready to download the final document, with google docs a) you have to reimpose those margins, fonts, etc which is a pita; and more importantly b) you run the real risk that on reimposing those margins, fonts etc the page count will change, requiring another whole round of editing to get it under the required page count. Whereas this appears to keep the document in odt the entire time and hence there'd be no nasty surprises at the end.

    Having said all that, there's no way to add citations. Google docs has a close to useless implementation of citations (imagine 5 scientists collaborating on a document, each of whom have their own citation databases with thousands or tens of thousands of entries, and then go and have a play with citations in google docs. Try not to giggle too much when you realize how well that'd go..). But given open/libreoffice has really good integration with zotero, and zotero is also open source and browser based, it seems like these two could be made to talk to one another, which for academic collaborators would be a HUGE feature, jumping it way ahead of any other collaborative tool I've ever seen. And believe me, collaborative writing is so central to my work that I play with *anything* that looks like it might be an improvement on google docs or the nightmare of emailing around multiple copies of a document with 'track changes' in heavy use.

      When importing an ODT into Google Docs, it is converted to a format internal to Google Docs. The blog post explains that in WebODF / ownCloud Documents, conversely, no conversion occurs.

      For example, WebODF does not support displaying columns yet, but if you have loaded a document with columns, after saving, the columns will still be there.

      Since the document is part of the DOM, you can edit it programmatically with JavaScript. So adding functionality for scientific citations is as easy as any website prog
