Apache OpenOffice vs. LibreOffice
================================================================================
> The two open source office productivity suites are similar, yet one appears to have a slight advantage.
[Apache OpenOffice][1] and [LibreOffice][2] are the modern descendants of OpenOffice.org. For the last few years, almost all Linux distributions have included LibreOffice as their default office suite. However, in the past eighteen months, OpenOffice has reappeared, newly organized into an Apache project, and free software users now have the choice of two full-featured suites instead of one.
Users also have the difficulty of deciding between two almost-identical choices. The two diverged three years ago, and while that can be a long period in software development, in this case, the differences are only starting to become obvious. While considerable cleanup has gone on behind the scenes, the feature sets and underlying logic in both has mutated in only minor ways from the days of OpenOffice.org.
Here and there, you can find new features in the individual applications, especially in the Writer word processor. However, most of the differences are at a higher level, in support for formats and fonts, the policy towards extensions, and, most of all, in the efforts to modernize and standardize the interface.
### Differences in the Apps ###
Most of the features in LibreOffice's and OpenOffice's applications are the same. In Draw, there appear to be no difference at all. In Impress, the main difference is that LibreOffice's latest release includes support for controlling a slide show from an Android device. And although the selection of slide backgrounds differs between the two, either selection should be adequate unless you are looking for a favorite. Similarly, the greatest difference between the two versions of the Calc spreadsheet is that, in LibreOffice's, you can create data forms.
Even in Writer, the most popular application, the differences are generally in a minor key. In LibreOffice, the status bar at the bottom of the editing window now includes a word and character count. In addition, LibreOffice's comments can be anchored to paragraphs rather than a single point, and, in a correction of a longstanding bug, in footnotes now display besides the text to which they refer. LibreOffice also adds a simplified Find field, similar to one in a web browser, while omitting the option to insert a graphical horizontal line -- a feature that few must have used for the last decade or more.
### Formats and Fonts ###
Some of the more noticeable differences fall under the category of format and font support. For instance, OpenOffice continues to support saving to formats that have gone out of fashion, such as AportisDoc (Palm) and Pocket Word. It can open .docx files, but, unlike LibreOffice, not save to it.
LibreOffice also has the advantage in font support. The latest version supports OpenType, the preferred format for modern fonts because of its support for multiple languages and advanced typography. Even more importantly, by going to File -> Properties -> Fonts, you can embed fonts into the document, eliminating with a single click the need to ensure font compatibility.
Such features give LibreOffice a decided edge when exchanging files with Microsoft Office users. In general, neither OpenOffice nor LibreOffice interact best with Microsoft formats when a document is mostly text and contains a minimum of tables, draw objects, and complex formatting. In both, for example, you are best off sharing something like a brochure in .PDF format rather than the native Open Document Format.
However, if you do exchange native and Microsoft formats, LibreOffice has some decided advantages. Not only does it both read and write to recent Microsoft formats, but its advantages in font handling removes any need for font subsitution -- a major cause of problems when exchanging files. While other problems remain, such as differences in feature implementation, LibreOffice should generally be the more reliable handler of Microsoft Office files.
### Extension Policies ###
Both OpenOffice and LibreOffice support well-rounded collections of extensions that can be downloaded and added in minutes to enhance or alter features. In most cases, an extension that works with one will work with the other.
The difference is that, with LibreOffice, you don't have to install the most popular extensions. Instead, LibreOffice installs with them already enabled or integrated. These extensions include Lightproof, a basic grammar checker; Report Builder for summarizing and printing from data bases; Presentation Minimizer for reducing the size of presentations; Wiki Publisher for blogging, and Presentation Console for delivering slide shows, as well as a number of others.
All these extensions are available for OpenOffice as well. The difference is that, with OpenOffice, you need to know about them and deliberately find them. Effectively, this limitation makes a number of features unavailable to new users. When OpenOffice (and LibreOffice) have made such efforts in recent releases to provide useful modern templates and clip art, this omission is a crippling oversight, especially when it is so easily corrected.
### Interfaces in Transition ###
In the twelve years that Sun Microsystems and Oracle have owned the OpenOffice.org code, the interface, like so many features, was almost entirely neglected. The result is that today, both OpenOffice and LibreOffice are suites with a healthy set of features, but interfaces that are generally stuck in the mid-1990s. Some superficial aspects have been removed, but far more remains to be updated.
In the latest release, OpenOffice's efforts to overhaul the interface have been restricted largely to the sidebar, an feature that has to be specifically enabled in LibreOffice from Tools -> Options -> LibreOffice -> Advance, and is labeled as "experimental."
The sidebar is a collection of features, primarily for manual formatting. Since this use comes at the expense of encouraging the use of styles, as the logic of the code intends, it is easy to dismiss. However, at its best, the sidebar is an immense simplification of some of the tabs for formatting characters and paragraphs, such as the Border tab in all applications, and the Format tab for spreadsheet cells. With luck, its re-conceptualization of controls will eventually find its way to the menus and style dialogue windows.
LibreOffice has been even more adventuresome. For example, the task pane in Impress, while similar to the sidebar, summarizes most of the steps in slide design in the names of its tabs.
But it is the Writer editing window where most of LibreOffice's interface improvements have taken place. A word and character count has been added to the status bar at the bottom of the window, and the cramped sub-menus for managing and editing templates have been replaced with a stream-lined interface in which buttons replace drop-down menus.
Even more obvious, the main text frame has been reduced in LibreOffice to cross-hairs at the four corners. In the same way, headers and footers are invisible until you click where they should be, when four small right angles indicate their borders.
A less successful effort is a tab in LibreOffice's editing window for managing headers and footers. Aside from the fact that the tab encourages manual formatting, it has the annoying habit of hiding part of the first line of a new page as it is typed.
These efforts are far from complete, although LibreOffice has also rearranged options in a number of dialogue windows. At times, they make LibreOffice a disconcerting mixture of vintage interfaces and modern minimalism that can be disconcerting to move between. However, at least LibreOffice is trying to address the long-delayed problem of the interfaces -- something OpenOffice has not had much time to consider.
### Making a Choice ###
An average user, whose documents are rarely longer than two or three pages, would often have to check the title bar to be sure whether they were using LibreOffice or OpenOffice. However, depending on their needs, advanced users will probably find LibreOffice currently has a small, but definite advantage.
This advantage is hardly to be unexpected. For one thing, LibreOffice had many months to advance while OpenOffice was concerned with setting up governance and doing a code audit. These tasks might be useful and necessary, but they do not make for improvements in the code that ordinary users are likely to notice.
For another, the LibreOffice fork was begun largely by members of [Go-oo][3], an unofficial fork of OpenOffice.org that wanted to accelerate change. While Apache OpenOffice was forming, LibreOffice attracted talent around the world who wanted to code and were excited by the idea that everything was suddenly up for reconsideration.
Nobody has any done a census, but my impression is that when the OpenOffice.org community divided, the more adventurous contributors chose to focus on LibreOffice, although a few, such as the semi-independent documentation team, deliberately work for both projects.
However, the most important advantage for LibreOffice is what might be called the license-drain. That is, while the Apache License is compatible with LibreOffice's Lesser GNU General Public License, the Less GNU General Public License is incompatible with the Apache License. In other words, while LibreOffice can borrow code freely from OpenOffice, OpenOffice cannot borrow at all from LibreOffice. Strictly speaking, it must do clean-room implementations of features it wants to borrow from LibreOffice.
This situation may change, especially since Apache OpenOffice enjoys enormous name recognition compared to LibreOffice. Yet LibreOffice has quickly earned widespread support and has an active community that has done more in three years than OpenOffice.org managed in twelve.
For now, whether you use Apache OpenOffice or LibreOffice is likely to make very little difference unless you need a particular feature. However, I suspect that, unless something unexpected happens, LibreOffice's slight advantage is only going to widen. Whichever you decide on, you may want to schedule a re-evaluation in a few years' time.

Apache OpenOffice vs. LibreOffice 详解
================================================================================
> 这两个开源办公套件产品很相似,然而某一个貌似已经开始具有轻微的领先优势……
[Apache OpenOffice][1]和[LibreOffice][2]都是OpenOffice.org的现代衍生产品。最近几年几乎所有的Linux发行版都将LibreOffice作为它们的默认办公套件。然而过去18个月来OpenOffice作为Apache项目又重新回到了人们的视线对于这两款全功能办公套件现在自由软件用户可以进行二选一咯~
然而即使是用户在两种几乎一样的选择中做决定也会有困难。三年前这哥儿俩分了家三年时间这对于软件开发来说是很长的一段时间即使是这样OpenOffice和LibreOffice之间的不同却刚刚开始显现。除去那些明显已经去掉的过时特性单说功能集合与基本逻辑自从OpenOffice.org时代以来这两者都几乎没有什么大的改变。
纵观整个套件只有个别应用里能发现一些新功能主要集中在Writer的文字处理方面。其实它们两者之间的大部分区别主要存在于更高的层面例如对格式和字体的支持、对插件扩展的政策等更多的不同则体现在是否紧跟时代以及对标准化接口的努力程度上。
###具体各程序间的区别###
LibreOffice和OpenOffice之间的程序大部分都是一样的。例如它俩的Draw看起来完全没有区别再说Impress主要的区别就是LibreOffice最新版支持使用Android设备控制幻灯片放映除了幻灯片背景以外两者其他方面没什么不同都能很好的胜任日常使用除非有特殊偏好用户选择哪一款都可以同样在Calc电子制表软件中两者最大的区别就是你可以在LibreOffice里创建数据表格。
即使在用户最常用的Writer程序中两者的区别也很小。LibreOffice这边编辑窗口的底部状态栏现在新包含了一个字词计数器审阅标签也不再局限于某个单个点现在可以附加在配图上另外LibreOffice终于解决了“脚注无法紧靠对应文本显示”的bug除此以外LibreOffice还添加了一个简易搜索栏与web浏览器上的那种类似同时去掉了图形水平线的选项这个功能过去十几年来几乎从没人用过。
###格式与字体###
一些更明显的区别体现在格式分类与字体支持上。例如OpenOffice始终支持一些较老的保存格式像AportisDocPalm版和Pocket Word。另外它也可以打开.docx格式的文件但是无法像LibreOffice一样将文档保存为docx格式。
LibreOffice同样在字体支持方面占有优势。它对多语言和高级排版工艺始终有较好的支持因此最新发布版本能够支持OpenType这样的现代字体首选格式。更重要的通过“文件->属性->自体”,你能够将字体嵌入到文档中去,无需任何繁琐操作,就能确保字体的兼容性。
这样的特性使得LibreOffice在面对微软Office用户转换格式的时候得到了决定性的1分。因为通常OpenOffice和LibreOffice都无法很好处理微软格式的文档特别是那些又有文字表格又有图形对象再加上复杂格式的文档。因此如果你要共享复杂一些的文档例如宣传手册最好使用PDF格式而不是Open文档格式ODF
然而如果你确实需要转换一些本地或微软的文档LibreOffice拥有一些决定性优势。它不仅能读写大多数微软文档而且它对字体替换处理的很好而这正是文档格式转换时要面临的一个主要问题。尽管其他问题仍有不少例如在特性实现上有所不同但LibreOffice在处理微软Office文档时确实应该是一个更可靠的选择。
###对待插件扩展的政策###
OpenOffice和LibreOffice两者都能很好的支持插件扩展想要加强或替换某个特性的时候用户只需要几分钟就能下载并安装完毕。大多数情况下同一个扩展在OpenOffice和LibreOffice上面都能工作的很好。
区别就在于使用LibreOffice时你无需亲自安装那些最流行的插件扩展。相反LibreOffice已经帮你安装整合好了。例如基本语法校验工具Lightproof、数据库汇总和打印工具ReportBuilder、演示文稿压缩工具PresentationMinimizer、博客用户喜欢的WikiPublisher、还有幻灯片配置工具PresentationConsole等等。
以上这些扩展在OpenOffice下同样可用。与前者不同的是使用OpenOffice时你首先需要知道有这些扩展然后专门去找到它们这样一来很大程度上限制了新用户对很多功能的体验。因此当OpenOffice在最近发布的版本中尝试努力提供更好用的现代模板和剪贴画时这样的疏漏就成了一个非常严重的不足特别是当它很容易弥补的时候更何况LibreOffice同时也提供了自家最新的模板和剪贴画
###接口的更新换代###
在OpenOffice.org属于Sun和Oracle的12年日子里它的代码和接口就如同许多优秀特性一样几乎被完全忽略。如今的结果就是OpenOffice和LibreOffice作为套件产品都各自拥有一整套优秀的功能但是它们的接口却仍停留在上世纪90年代的水平。只有表面上的一些老旧接口被移除其实大部分仍然亟待更新。
在最新的发布中OpenOffice试图彻底更新自己的接口但是却由于“导航栏”而被迫受阻。导航栏这一特性如今已经成为“用户体验”的标签在LibreOffice中你可以通过“工具->选项->LibreOffice->高级”找到关于它的设置。
导航栏是一组功能集合,主要用于用户手动格式化。【【【这一特性鼓励用户使用样式,就代码编写人员的逻辑来说,这一点很容易被忽略。(这一句各种纠结不明白啥意思啊啊啊啊啊=。=)】】】然而,它最大的好处是,大大简化了字符和图形的格式化标签页,例如原本所有应用程序中都有的加粗选项,以及电子表格单元格中的“格式”标签页。幸运的是,导航栏还重新定义了菜单和样式对话框窗口的概念。
LibreOffice还拥有更多的“冒险创新精神”例如与导航栏类似Impress中的任务面板摘要显示了大多数幻灯片设计步骤中要用到的选项卡名称。
在Writer编辑窗口中LibreOffice的大部分接口已经完成改进窗口底部的状态栏中添加了一个字词计数器原本负责管理和编辑模板的狭窄子菜单如今也已被高端大气上档次的流线形按钮所取代。
更明显的LibreOffice中的主文本框架被精减为四个边角的十字准线。同样的页眉和页脚也默认改为不可见要想找到它们四个小直角标明了它们的边界位置点击就可以出现。
不太成功的一点改进是LibreOffice中管理页眉页脚的编辑窗口。除了【【【使用标签页鼓励手动格式化这一事实和上面那纠结的一句一样这是什么意思啊啊啊啊啊=。=)】】】,比较恼人的是,当在新一页的第一行输入的时候,已经输入的一部分总是会自动隐藏。
尽管LibreOffice还重组了许多窗口选项但是这些努力远没有结束。有时开发人员会让LibreOffice变成传统框架与现代极简艺术的混合体看起来有些不伦不类但是至少LibreOffice正在尝试着解决长期搁置的接口问题而这些OpenOffice甚至都还没来得急意识到。
###做出选择###
如果文档不超过2到3页一般用户可能需要时常检查标题栏看自己用的是LibreOffice还是OpenOffice。然而对于进阶用户而言LibreOffice目前可能更有优势。优势并不算大但是很明显。
这一优势的确很难被忽略。原因首先在LibreOffice已经确立了好几个月时间优势的情况下OpenOffice却仍在专注于管理权和代码审计这些工作也许有帮助也有必要但是普通用户更愿意看到他们对代码做出更多的改进工作。
其次LibreOffice的开发人员大部分是[Go-oo][3]的前成员这是OpenOffice.org的一个非官方项目组以“快速完善”为目标。当Apache OpenOffice项目组还在筹建中的时候LibreOffice就已经吸引了全世界酷爱编程、热衷变革的天才们。
没有人做过准确的调查但是我印象中当OpenOffice.org社区分家的时候大部分富于冒险创新精神的贡献者都选择了LibreOffice同时有一些半独立的文档小组在谨慎地同时为两个项目工作。
其实LibreOffice最重要的优势或许可以称之为“吸血许可证”。怎么个意思呢就是OpenOffice的Apache许可证兼容LibreOffice的Lesser GNU通用公共许可证但是LibreOffice的Less GNU通用公共许可证却不兼容OpenOffice的Apache许可证。换句话说LibreOffice可以随意自由地从OpenOffice“借”代码但是OpenOffice却根本无法从LibreOffice“借”到任何东西。严格地讲如果想从LibreOffice“借”来某个功能OpenOffice必须完全依靠“净室clean-room”来实现。
这一情况有可能会改变尤其是当Apache OpenOffice比LibreOffice拥有更高的知名度的时候然而LibreOffice的支持者们正在迅速扩张它的社区非常活跃短短3年间所做的要比OpenOffice.org十二年来做的还要多。
现在除非你特别需要某个功能使用OpenOffice还是LibreOffice几乎没有区别。但是我断定除非发生某些不可预料的事情否则LibreOffice的优势将会越来越大。无论你选择支持哪一方几年内也许你会对它重新作出评价。
