<ericP> should this http://dbooth.org/2015/fhir/bnodes/confirmed.ttl be a 404?

ericp, you're still sharing your desktop

yes, i didn't upload it to my web site

dbooth: It looks like the reasoner *is* doing the inference, but it just is not showing the blank nodes in the DL query or in the Protege interface. But it is making the inference.
... This is demonstrated by lines 33-43 "Propagating inference upward".

* You've invited zakim to :#hcls (public-irc.w3.org)

* Zakim (zakim@public.cloak) has joined #hcls

<Marc_Twagirumukiza> It's a good new that BN works. I support

* Zakim sees ericP on the speaker queue

tony: FHIR entities can have IDs. If something has an ID, can we use that to make a URI?

lloyd: the ID is only unique within the resource, but not within a bundle of multiple resources.

* Zakim sees ericP, dbooth on the speaker queue

lloyd: various things can be used to uniquely identify things. But it depends a lot on business context.

eric: expected FHIR to enable that two Bobs are the same.

lloyd: People would like FHIR to solve that problem, but it's not a technology problem It's an info problem. FHIR cannot make info magicaly appear.
... You would need to say that a particular identifier is *trustworthy* as a unique ID, but the others aren't.
... There's a person resource that you can use to link multiple patient records.
... You can make these assertions in your data, but some of them may be erroneous.

eric: it would be nice if the graph automatically connected them together where it is asserted

<Zakim> ericP, you wanted to say that the next testing step is indistinguishable from assuming they work so let's assume they work.

<Zakim> dbooth, you wanted to say that it sounds more complicated to *sometimes* generate URIs (if an ID is present) but not always

Proposed resolution: Okay to use blank nodes. They appear to work with OWL reasoning.

RESOLUTION: Okay to use blank nodes for elements. They appear to work with OWL reasoning.

Eric and Josh's generation of RDF from FHIR

Eric: I updated to DSTU 2.
