WebODF: JavaScript Open Document Format Editor Deemed Stable 91

Posted by Unknown Lamer from the google-docs-for-the-rest-of-us dept.
oever (233119) writes with news that WebODF (an Open Document Format editor written entirely using Javascript and natively rendering the XML document using CSS) 0.5.0 has been released, and the developers are declaring this release stable enough for every day use. TheMukt chides Google for not supporting the OpenDocument Format well and claims that the newly released WebODF 0.5.0 in combination with ownCloud is the answer to this deficiency. A WebODF developer blog highlights all the goodies in the first WebODF release where the text editor is considered stable and made available as an easy to use component. These include extensive benchmarking, unit testing, and advanced HTML5 techniques to give the editor a native feel. There's also touch screen support, and better support for real-time collaborative editing. A demo shows off a few of the features.

    This is fast and responsive. Does it avoid long-standing Word problems, such as figures that jump away from captions, paragraphs that adopt the adjacent style just because you're moving them around, and the like? For professional writing, I'll stick to LaTeX for now. For collaborative writing, something like this could be nice (and improve on half-baked solutions like the editor in OneDrive (very slow) or Google Doc (not word-compatible). So, I think this would have to be able to export / import Word docs seamlessly, due to business pressure everywhere...

        In collaborative mode as used in ownCloud, each document edit is stored as an operation such as AddImage, AddText, MoveCursor etc. (WebODF implements Operation Transformation for editing) With this stack of operations and the original document, any intermediate state of the document can be recreated. There is currently in WebODF no method for displaying changes in a single document, but it's straightforward to show different versions of a document side-by-side in your website or application.

      WebODF uses OpenDocument Format (ODF) as the runtime document model. That means that there is 0 (zero) data conversion when loading and saving a document. It does not support OOXML, but it could load an OOXML document if it was converted to ODF. It is not clear that the same approach (style unchanged XML with CSS) could work with OOXML. Have a look with your browsers 'Inspect Element' function in the demo. The DOM is ODF XML, not HTML.

      It can use fonts embedded in the file and fonts provided via css. Fonts provided via css can be stored on the server or, when WebODF is used in a desktop or mobile application, on the local machine. There is not really anything for font license issuers to freak out about. PDF can embed fonts too as can OOXML. Providing fonts via css is common on the web these days and of course one should check the license when doing so.

      I actually would not consider this ready for every day use. It does not even play nicely with what I have at home as the following are broken.

      1: It can't handle multiple columns.
      2: No real support for index work.
      3: Can't create tables or modify number of columns/rows.
      4: No header/footer support.
      5: No footnote support.
      6: Embedded images tend to overlap text.
      7: The equation stuff is not supported.

      That said this is still bad ass and I look forward to seeing how it progresses.

      On a serious note: WebODF started as a C++ extension to Webkit. It turned out that the logic for the document editor was not the performance bottleneck and might as well be written in javascript. This sped up development a lot. Naturally, C++ has better type checking than javascript but by using closure compiler this can be partially alleviated. WebODF is 100% annotated with type information.

    Link zotero to this and you'll have a solution academic collaborators have been looking for since the beginning of word processing.. Seriously, we need a collaborative writing platform which allows multiple authors to add citations.

    • To be honest, I don't think ODF is optimal for this. To me it still feels like "moderate progress within the bounds of the law". You could easily - well, more easily than many other things - make a collaborative, real-time editable "Authornet", but it wouldn't probably have much in common with local-file-based editors. It would be more like some kind of a distributed object database. (I think the VPRI people are actually heading roughly in this direction.)
