Hi Everyone,

Here are the notes from the Endpoint ID Design Team Meeting (EID-DT).

Attendees

*         Ron Colvin

*         Henk Birkholz

*         Dave Waltermire

*         Cliff Kahn

*         Danny Haynes

Note Well

Agenda

*         Explain triples (subject, predicate, object), relationships, and metadata

*         Discuss various open threads on the list as needed

*         Next steps

Materials

*         Slides from meeting (see attached)

Notes

*         The team went through an example on triples: subject, predicate, and object.  The example included the definition of various triples, instances of those triples, and how the triples could be represented as containers.  For more information on the example, I would recommend watching the recording when it is available.

*         There was a question about where provenance fits in with these triples and how you could associate who was asserting a particular triple.  It was explained how triples can be used as the basis for expressing all information and how reification can be used to associate additional information with the triples.  The following link was provided as an example of how reification works (http://stackoverflow.com/questions/5671227/what-does-reify-and-reification-mean-in-relation-to-rdf).

*         There was a comment that we may want to define higher-level concepts like server, address, etc. rather than getting into the weeds.

*         There was some discussion around how we might represent these triples in the Information Model.  It was suggested that using a table that describes the object, properties of that object, and the relationships with other objects might be one way to approach this.  Then, where necessary, create types and specify formats for values.

*         We did not end up having time to discuss any of the open issues on the list, but, we can continue working on the list.

*         Next steps were discussed.  The triples example should be updated and further discussed before sending to the list.  We need to reach consensus on the proposed changes for the Information Model as well as close out issue #20 to ensure we have the most up-to-date version in GitHub.

Action Items

*         Update the example of using triples to also include the concepts of reporting, observation, and possibly others for the next EID-DT meeting.  After that, annotate the example and share with the broader list. (Henk Birkholz)

*         Share links to IETF documents that may demonstrate how we can represent triples in the SACM Information Model. (Dave Waltermire)

*         Provide a possible definition for "network interface" on the list.  (Henk Birkholz)

*         Review the diff between revisions 01 and 02 of the IM to determine what text, if any, is missing (???)

*         If positive consensus is reached, make the changes and include a sentence or two to describe what information goes in each new section.  Update on GitHub.  (Danny Haynes)

Please let me know if I missed anything, got anything wrong, or if you have any questions.

Adam will post the recordings when he returns.

Have a great weekend.

Thanks,

Danny
