A customer has been interested in adding Wiki support to their web site. There are many Java packages available, but I found two that seemed especialy easy to set up and use:
I have been looking at web based open source document management, authoring tools, knowledge management, etc. that might work well with version 2 of my KBtextmaster product that I hope to release first or second quarter of 2005. The KBtextmaster is a service that provides REST and XML-RPC interfaces for categorizing and summarizing text (*). I am planning on providing free "glue" code for Python based Plone and several Java open source projects.
(*) I m considering support for RDF tuple extraction from text (based on a few ontologies), but that is likely to be a separate product in the future - that code is still 'research quality' and probably will be for some time.
