Shotoku
Shotoku is designed to provide easy access to content repositories in which you can store data, bind metadata, revision content, and provide branching and merging strategies. This means Shotoku can interface with repositories such as the Java Content Repository (JSR 170: JCR), Subversion, and file-system based repository implementations that aim to support basic revisioning mechanisms.
Here are some of the currently implemented features:
- Three content managers: the first and default SVN-based, JCR-based and a local file system repository.
- Because a local working copy is present, data reading is very fast (SVN repository implementation).
- Data writing is reliable, because data is sent straight to the repository, without touching the working copy (SVN repository implementation).
- Shotoku can work in "embedded" mode in stand-alone applications, as well as a component in an application server.
- Shotoku allows you to "inject" content into any POJO using annotations (currently supported only in app server mode). POJOs which are Shotoku aware are automatically updated when a user updates a node in a Subversion repository Shotoku is configured to reference. Content can be anything and there are no structural requirements placed on the repository - even existing Subversion repositories can be referenced by Shotoku without modification.
- A simple search mechanism.
- Integeration with Apache Velocity - you can easily store templates in Shotoku to create higher level application features such as content and blog engines.
- Feeds component - automatic generation of rss, atom and rdf feeds/ podcasts, configured through a xml file, together with arbitrary feeds aggregation. You can see feeds already at work on JBoss Labs - just click the "Feeds" link in navigation or simply here.
- Blog component.
- A simple cache with "renewable" values.
As an example application that can be built using Shotoku, a blog and podcasting engine has been created using the template mechanisms available in Shotoku. In fact, all the feeds you see on JBoss Labs, the blog and podcasts, are driven using content stored in our Subversion content repository. This means, to publish a podcast, you just check in your content to a directory of your choice in your svn repository. Shotoku automatically applies the selected templates to produce content feeds. These feeds are described using simple xml files. This is just one of the many application level uses of Shotoku.
But that's only the beginning of what Shotoku will consist of. Here is a short plan for the future:
- Clustering support using JBoss Cache
- Semantic web integration
- Improved searching
- A servlet for accessing files based on defined access privileges
