Collabora Onlineis anopen sourceonline office suitebased onLibreOffice,enabling web-basedcollaborative real-time editingof word processing documents, spreadsheets, presentations, andvector graphics.[6]Optional apps are available for desktops,laptops,tablets,smartphones,andChromebooks.

Collabora Online is developed by Collabora Productivity, a division ofCollabora,which is a commercial partner of LibreOffice's parent organization, The Document Foundation (TDF). TDF states that a majority of theLibreOfficesoftware development is done by its commercial partners, Collabora,Red Hat,CIB, and Allotropia.[7]

Features

[edit]

Collabora Online can be accessed from modernweb browserswithout plug-ins or add-ons. Documents, spreadsheets, presentations and vector graphics can be edited collaboratively.[8][9]

Collaborative functions include comments which other users can respond to, document version history which enables the comparison of documents and restoring, etc. Collaborative functions may also include integrated video calls or chat whilst collaboratively editing documents, features like these are possible with integrations with enterprise cloud solutions such asNextcloud,ownCloud,Seafile,EGroupwareand others.[10]Collabora Online can be integrated with any application.

Device support

[edit]

Client apps are not required to access Collabora Online which only needs aweb browser;However, optional apps are available for most devices that run the following operating systems:Android,ChromeOS,iOS,iPadOS,Windows,macOSandLinux.[11]

These optional apps share the same core LibreOffice Technology software with Collabora Online, resulting in document consistency between them. Software development of the LibreOffice core therefore normally benefits the source code of Collabora Online server and all of the client apps simultaneously.[12][13]The apps workofflinewithout the need for a connection to a local server or the cloud, support for integrations withcloud storage servicesis still possible. The mobile apps have touch-optimized interfaces that scale across varying screen sizes. TheChromeOSapp which is used inChromebooks,Chromeboxesand tablets, edits documents in the Play files folders.[14][15][16]

Collabora Online supports ISO/IEC international standard ISO/IEC 26300Open Document Formatfor Office Applications (ODF – odt, odp, ods, odg). It also supports Microsoft's XML formats (docx, pptx, xlsx) and Microsoft's legacy binary formats (doc, ppt, xls). Other formats supported includepdf,png,csv,rtf,andepub.[17][18]Microsoft Visio,Microsoft Publisher,Apple Keynote,Numbers,Pages,and other file formats can be imported, the same asLibreOffice supported file formats.[19]

Server

[edit]

Collabora Online allowscollaborative real-time editingof word processing documents, spreadsheets, presentations and vector graphics.[8]The server or servers can be hosted locally or with a provider, privately hosted cloud services allow applications and data to remain under the control of the respective users. Collabora Productivity supports Collabora Online server instances forDebian,UbuntuCentOS,openSUSE,UniventionVirtual Machines andDockerimages.[22][23]It is often integrated with file sharing and collaboration cloud platforms, such asNextcloud,ownCloud, Seafile and EGroupware, which are functionally similar toDropbox,Google DriveandMicrosoft 365,these typically include email, contacts, calendar, file synchronization and sharing, calls, chat and video, with apps stores. Close integrations are possible, enabling things like the possibility to edit documents within a chatroom or a video call, as with Nextcloud's built-in video-conferencing tool Nextcloud Talk. Collabora Online server can integrate simultaneously with several cloud solutions such as aforementioned and alsoAlfresco,Kolab,Mattermost,Moodle,Nuxeo,SharePointand others.[24]

The server can be installed from packages, or during development, for simplicity, from a docker image. The Docker website indicates that the Collabora Online Development Edition (CODE) Docker image has been downloaded 50 million times.[25]Asoftware development kit(SDK) includingAPIspecifications and integration instructions is available, along with sample integration code snippets for several programming languages.[26]

Collaborative functions include comments which other users can respond to and document version history enabling the comparison of documents and their restoration, and other things.[9]

In 2021 aremote worksolution was made available byCanonical,Collabora, and Nextcloud which includes the Collabora Online office suite, it installs on Intel NUCs orARMbasedRaspberry Pi 4s,it is preconfigured and automatically updates itself, it is called Nextcloud Ubuntu Appliance.[27][28]

In 2022 support for theOpenPOWERarchitecture was added, complementing existing support for x86-64 andARM64,this was the result of a partnership with IT service provider 21unity who offer aNextcloudEnterprise solution called 21unity CLOUD.[29]

Digital sovereignty

[edit]

Collabora Online is fully auditable open source software, uses open standards, is self-hostable and does not require an account from a third party provider to edit files. In July 2020, the European parliament published a briefing titled Digital sovereignty for Europe, detailing concerns that citizens, businesses and Member States of theEuropean Union(EU) are losing control over their data, it explains the economic model used by Apple, Amazon, Facebook, Google and Microsoft is largely based on the collection and exploitation of online users' data.[30]Judgements such as “Schrems II” show that it is delicate to rely on solutions from the large cloud providers when it comes to processing and storing sensitive personal data.[31]Digital sovereigntyhas been an increasing concern in the EU for several reasons since thePatriot Actenacted in October 2001, the continuing legal privacy conflicts between the USCLOUD Actenacted March 2018, and the EU'sGeneral Data Protection Regulation(GDPR) implemented May 2018.[32][33]

The French Ministry's IT infrastructure director stated safety of the data of their citizens and employees as a reason for deploying Nextcloud-based private cloud for the French Ministry of Interior. The Dutch Ministry of Education, the German federal government, and the Swedish federal government agencies are deploying Nextcloud-based private cloud for similar reasons and to increase competition.[34]

Interoperability challenges require effort to maintain digital sovereignty with office suites, such as the interoperability of documents with other office suites, viewing and editing. Some areas where interoperability challenges arise with Microsoft Office include, document standards, font licensing, and secret document display algorithms. Examples are:

  • As of November 2024,Microsoft Office file formats default to Microsoft XML, they do not claim to default to theopen standards-OpenDocument(ISO/IEC 26300) or Microsoft's -Office Open XML(ISO/IEC 29500).[35]
  • Microsoft Office 2013 introduced undocumented display algorithms that effect document line breaks in undocumented ways, meaning that even when using identical fonts or metrically equivalent fonts, document line breaks may no longer appear in the same place as originally authored by Microsoft Office, when viewed or edited using another office suite. The undocumented display algorithms were introduced soon after Microsoft switched to use Microsoft XML. It is necessary for competing office suites to work out how this is done.[36]
  • Microsoft Office 2007 introduced new default fonts that are not freely distributable like the previous default Microsoft Office core fonts. Other computer devices are required to purchase a licence for Microsoft office even if they are using another office suite, otherwise viewing or editing these documents could render them incorrectly. To help mitigate this newmetrically equivalentfonts were developed with similar widths so that line breaks etc were more likely to appear in the right place in documents, but the fonts would still look different, so documents created in Microsoft Office would still not appear as the author had created them.

Technology

[edit]

The core of Collabora Online is written inC++.It uses the LibreOfficeKit, a programming interface that allows the reuse of most of the existing LibreOffice code and the saving, loading and rendering of documents. The basic principle of Collabora Online is that documents never leave the server. The parties working on the documents see tile-rendered images of the document and send their changes back to the server. The visible user interface of Collabora Online is written inJavaScript.For file access and authentication with a file hosting services, Collabora Online uses the WOPI protocol developed byMicrosoft.This means that Collabora Online can – in theory – be used with any instance allowing a Microsoft 365 integration.[37]

Reviews

[edit]

Various online and print publications have discussed Collabora Online. In December 2016 the technology websiteSoftpediamentioned the availability of collaborative editing in version 2.0 and the integration with ownCloud, Nextcloud, and other FSS solutions.[38]The technology websiteZDNETreported in June 2020 that Collabora Online from version 19 of Nextcloud will be delivered as a standard office package and that within the native video conferencing software Talk direct editing of documents is now possible.[39]The technology blog OMG! Ubuntu! covered the release of the Android and iOS apps pointing out the possibility to use them in offline mode.[40]In September 2020Linux Magazinecompared Collabora Online withOnlyOffice,mentioning the flexibility and platform independence of both tools and pointing out the large set of features Collabora Online draws fromLibreOffice.[41]

History

[edit]

The former LibreOffice development team fromSUSEjoined Collabora in September 2013, forming the subsidiaryCollabora Productivity.[42]In 2015 Collabora andIceWarpannounced the development of an enterprise-ready version ofLibreOffice Onlineto compete withGoogle DocsandOffice 365(now called Microsoft 365).[43][44]In December 2015, the company's partnership with ownCloud and release ofCODE(Collabora Online Development Edition) was announced onJoinup.[45]In November 2016, Nextcloud announced their work and integration with v2.0 of CODE and their future work plans for improving performance, scalability, security and capabilities with Collabora Online.[46]In October 2020, Collabora announced the move of its work on Collabora Online from The Document Foundation infrastructure toGitHub.[47][48]A development version of Collabora Online is available called Collabora Online Development Edition (CODE).[49]
