Subject:   Re: Proj Launch Meeting Review

Thanks Ron. [for the draft of the record requesting comments on the meeting at SRI Friday, March 24, 2000, submitted by your letter on March 25, 2000]

Seeing your notes really brings home the fact of how hard it is to capture and organize data and information. I am seeing the picture a lot better now. The DKR is has 5 compartments, Experience, Learning, Knowledge, Node Map, and Problem(s). A late addition to this model is the DKR Problem. The DKR may (should) include a specific (set of) problem(s) so the users can focus efforts on what the DKR is intended to augment the solution of,!:)

Each user node of the OHS attaches individually to the DKR inteface, as well as having a separate interface directly to other OHS nodes. This might look like sphere (the DKR) with 5 divisions, with OHS nodes looking like cylinders attached to the sphere at one end and a OHS user node sphere at the other, attached all around the surface with a web of external connections ouside the DKR connecting all OHS user nodes.

Using your notes as an example, you would ue the OHS to submit your notes along with a list of external references to DKR Experience. The DKR adds the node and any connections to the node map, making it available to all OHS users. Collaboratively or individually, someone interested in design of iteractions with the user may find some references there and begin to accumulate snips of text and ideas from elsewhere on the WWW and unrev-II list archives. This author may then add some observations, maybe even compose a picture, then again submit this refinement to DKR Experience.

Other contributors may add or focus the content until the group decides that this information item is complete enough and aligns with a DKR Problem sufficiently to warrent moving the item to DKR Learning. If this item contributes something that the group feels is adequate to actually provide a basis for action on a DKR Problem, then pertainent content is added to DKR Knowledge.

Connections between evolving items are maintained sufficiently for a user to find source material. Absolute tracability is provided by the links from Knowledge items back through Learning and Experince nodes provided in three ways:

  1. By connections defined by contributors during the data/information evolution,

  2. By DKR internal associative mapping,

  3. Independent search by OHS tools.

Since the DKR effort is cooperative, there may be less need to track individual contributions with great detail. Besides, any user could attach a link with commentary to any element of any item in the repository. In general, if the comment is on an Experience or Knowledge item, then it would be stored as an Experience node so that a user of Learning or Knowledge items could put the commentary in context.

Best Regards,
