浏览/编辑 RDF/OWL 实例
我正在寻找一个图形浏览器来检查 OWL/RDF 实例的大型网络。 Protege 的实例浏览器并不是真正有用，如果 COE 支持实例浏览，我还没有发现如何支持。网络规模约为一百万个节点。
我希望能够搜索一个实例，扩展它以显示其关系，并从那里探索其他实例。图形化就很好，但是普通的 Jtree 也可以。
I'm looking for a graphical browser for examining large networks of OWL/RDF instances. Protege's instance browser isn't really useful and if COE supports instance browsing, I've not discovered how. Network size is around a million nodes.
I'm hoping to be able to search for an instance, expand it to show its relationships, and explore other instances from there. Graphical would be nice, but a plain Jtree would do too.

W3C 的 Tabulator 项目专为浏览 RDF 数据集而设计。它为 Firefox 提供了一个插件，可以方便您的探索。它还具有使用 AJAX 远程浏览数据的功能。

麻省理工学院 Simile 项目为 RDF 开发了一个多面浏览器，名为 Longwell。这是一个研究项目。现在开发已经陷入停滞，他们的演示似乎也被破坏了；然而，我可以证明它确实有效。我经常使用它来浏览本地计算机上极其杂乱的 RDF 实例数据集合。
Longwell 是作为 Java Web 应用程序编写的。它带有自己的码头服务器，或者可以作为servlet运行。它可以在内存中运行，也可以与各种后端一起运行。它解析 rdf/xml 和 n3，并且可以通过速度模板、CSS 和“Fresnel”RDF 显示本体进行高度可配置。可惜没有进一步追究；我发现它的用户界面非常令人愉快，特别有用的是，它可以浏览您喜欢的任何 RDF 实例数据，无论是否有模式或本体。
The MIT Simile project developed a faceted browser for RDF called Longwell. This was a research project. Development has now languished, and their demos seem to be broken; however, I can attest to the fact that it works. I use it regularly to browse an extremely miscellaneous collection of RDF instance data on my local machine.
Longwell is written as a Java web application. It comes with its own jetty server or can be run as a servelet. It can be run in memory, or with a variety of back-ends. It parses both rdf/xml and n3, and is highly configurable via velocity templates, css, and the 'Fresnel' RDF display ontology. It's a pity it hasn't been pursued further; I've found its ui to be very agreeable, and particularly useful is the fact that it will browse any RDF instance data you like, with or without schemas or ontologies.
