There are several plug-in examples in Symphony toolkit and on the web site. We will continue publish more plug-in examples. We hope more developers will contribute to Symphony by building plug-ins for it as well as for Notes and Sametime.
The plug-ins can be trivial like showing local weather/stock prices or complex ones like a front end of BI solution software (Hyperion or Cognus). The plug-ins could enable end users to retrieve data and embed them to documents (report or presentation). An equation editor provider like MathType can build plug-ins for different document authors. For example, equation editors for chemists that include lot of chemist formulas.
We can help you publish the information of your plug-ins on Symphony web site and point to your web site for end users to download and try them.
If you are a software application developer, please consider using Symphony in your solutions for business document editing like contracts, orders. Being its self a set of Eclipse plug-ins, Symphony can be used as a component in solutions on top of Eclipse/Lotus Expeditor.
If you are constructing solutions for enterprise that may includes document editing, please considering how to make the end user more productive by integrating document management with other business applications. You will see the benefit of the open document format and the open integration framework.
You may also re-brand Symphony to make it a special editor for particular users or tasks. For example, a medical record editor to help doctor record patient information, issue treatment order and keep treatment result. The editor could get data from other systems (HIS, LIS, PACS) and provide suggestion and alert by scanning symptoms and prescriptions in the document. The resulted document becomes the most complete medical record for future study and reference.
The open framework of Eclipse makes the performance looks not as good as the office suite built from proprietary C/C++ code. It can be solved by pre-loading the libraries (include Java) into memory. The approach is used by the proprietary suite vendor to make it looks running fast.
If you want to build a plug-in but have issues, please post messages at developer forum.
