Manu, Thanks for opening up this important topic, there is way too much confusion on these issues. 1. www.knoodl.com is an open, non-proprietary, commercial software product. 2. It supports all of the standard protocols for interoperation, TCP/IP, HTTP, and SPARQL. As far as I know these are the accepted protocols for interoperation on the World Wide Web, and there are no others. We do not support any proprietary protocols and do not even publish any API that might require such protocols. 3. We support most of the W3C standards for syntax and semantics including XML, XSD, RDF, OWL (lite, full and DL), SPARQL, and SWRL (coming very soon). 4. Support for widely accepted standards is what makes software proprietary or not. There is plenty of open source software that is highly proprietary. Any user can easily "backup" any of the content created in knoodl right now by using the "export" feature that we have supported for three years, this includes the wiki content and the semantic content (OWL and RDF). Otherwise you can get any of the semantic content via a SPARQL endpoint if that is better for the "mirror" application. Finally, all of the infrastructure of the World Wide Web including DNS servers, the internet communications backbone (fiber optic cables, copper cables and routers), and the ISP's that provide individual access are operated by commercial companies, are not free, and can be terminated at any time by any of the companies operating the infrastructure. None of the infrastructure of the internet is provided by federal, state or local governments for free. The only important issue is complete support for standards, that is how the internet came to be and what will continue to drive it forward - countless commercial companies and open source communities building products that provide support for open standards. michael lang On Tue, May 19, 2009 at 10:34 AM, Mike Lang Jr. <mikelangjr@revelytix.com>wrote: > Lee, > Thanks for bringing me in on this thread.
