Zope implementation of topic maps. Gnowledge Networking and Organizing System by nagarjuna on 2002/07/24 [Zope Products] seems to be an implementation of topic maps as a Zope product. Interestingly, it claims to have implemented facets, which an article by Steve Pepper, CEO of Ontopia suggests have been dropped in the XML version of topic maps because "... information resources could also be subjects (and hence topics). This rendered the concept of facets superfluous since metadata properties can now be assigned to a resource as characteristics of the topic that represents the resource." I read that paper the other night, and I need to go through it again because I couldn't work out have many of the different aspects were actually distinct. I'm sure it's because I was knackered, except in the case of facets - the note referenced above unfortunately comes at the end of the section so I only read it after being confused by them for a while.

Simpleface Wiki in OPML. I forgot to mention that the Simpleface website is available as an OPML instant outline document. If you're using radio, try opening this page in your outliner: http://www.simpleface.org/opml/HomePage.opml. It's a dynamically created OPML document of the contents of the Wiki. This was an exciting topic a while back on Scripting News, but [Russell Beattie Notebook] 8:01:12 AM    comment []

Answering to Roland Tanglao's questions: 1. My understanding is that everybody in the world who is on the same RCS and has bought the tool can change the outline. Is this correct? Yes, at the moment this is correct. 2. Are there any plans to enhance this tool so that I can define which members can edit and read the shared outline (similar to the "Editors Only" concept in Manila)? It would be cool if I could for example specify that sharedoutline "deal1" is only editable and readable by users 1 and 2 but not 3 and 4. I could sell a lot of Radio and SharedOutline licenses if it had such a capability. Security/access control is the next big thing with SharedOutline and we are working on it. With version 1.0 (or maybe with 1.1) of the tool you will be able define passwords for each outline, so you will be able to define who will be able to read/edit what. Another possibility will be defining which users users registered on the RCS server will be allowed to edit the outline. [Paolo Valdemarin: Paolo's Weblog] 7:54:25 AM    comment []
