15:01:11 <dbooth> Meeting: FHIR RDF
15:01:15 <dbooth> Chair: David Booth
15:02:54 <dbooth> Topic: DICOM
15:04:47 <dbooth> erich: Snippet of converted file: https://github.com/w3c/hcls-fhir-rdf/issues/149
15:05:16 <dbooth> ... Will test this on a bunch of data
15:11:44 <dbooth> dbooth: they have the datatype indicated, like "POLYGON .... ))"^^geo:wktLiteral
15:12:50 <dbooth> ... How easy is it to convert from DICOM JSON to this RDF format?
15:13:14 <dbooth> erich: I convert the files directly -- similar to DICOM JSON, but conversion to xsd literals.
15:13:40 <dbooth> ... Also doing SPARQL Updates on the models I have in memory.  Wrote my own magic property in jena to do it.
15:14:10 <dbooth> ... My program has an option called LongForm, which does bare minimum conversion to RDF
15:14:39 <dbooth> detlef: THe conversion is pretty simple.
15:15:04 <dbooth> ... Using an ontology, you know it is a polygon and you can use that format.
15:16:15 <dbooth> ericp: I'm down with that.
15:17:12 <dbooth> erich: Now converting 300k files.  Will load them into virtuoso and see if this data element is in there.
15:17:22 <dbooth> ... About 20B triples.
15:17:37 <dbooth> ... And I'll enable geosparql and see if it really works.
15:18:07 <dbooth> ... Mostly concerned about pathology, 1-2M polygons in one image.
15:18:38 <dbooth> ... Lots of labeling w deep learning pipeline.  Want see all tumor infiltrating sites within x distance of something.
15:19:00 <dbooth> Want to see that across the entire collection, for the pathologist to look at it.  That will exercise the index.
15:19:29 <dbooth> ericp: Doing Mondo DB stuff, when does it become available for query after loading?
15:19:45 <dbooth> erich: IDK.  Using our own sys for annotations and reviewing result sets.
15:20:09 <dbooth> ... Want to do spatial queries across multiple pipelines -- linking them all together
15:20:20 <dbooth> ... RDF is a great way to join all that data.
15:20:48 <dbooth> Topic: LLM trained on FHIR
15:20:56 <dbooth> eric: Saw a paper on it.
15:22:02 <dbooth> Topic: DICOM
15:22:25 <dbooth> erich: Also added example of sequence handling to issue 146
15:22:47 <dbooth> https://github.com/w3c/hcls-fhir-rdf/issues/146
15:24:03 <dbooth> detlef: individual items are descriptions of a region of interest.  We wanted to add data there.  3 choices: 1. Add DICOM attribute if there's an official one, and you're altering the original file.  Need to track the modifications in another attribute.
15:24:33 <dbooth> ... Option 2. LIke relation DB approach, foreign linking.  Ref the number of that region in the other file.
15:24:57 <dbooth> .... Option 3. Direct linking approach, that requires a different structure -- not an RDF list.
15:25:53 <dbooth> dbooth: Direct linking == by a URI?  Detlef: Yes.
15:26:37 <dbooth> detlef: Cannot do that w bnodes in an RDF list.
15:27:06 <dbooth> erich: Could use URIs in the RDF list.
15:29:13 <dbooth> ... Skolomized, or URNs for example
15:31:35 <dbooth> ericP: How do JSON users access these things?  Just go to the nth element?
15:37:11 <dbooth> Topic: Connecting DICOM RDF to FHIR RDF
15:37:28 <dbooth> dbooth: How do we write this up in the context of FHIR RDF work?
15:38:22 <dbooth> erich: Will see what work is already being doing on DICOM in FHIR
15:39:40 <dbooth> dbooth: I haven't heard back from Dave Beckett.
15:40:19 <dbooth> erich: Reached out to Sean Bechhofer.   Haven't heard back yet.
15:45:06 <dbooth> Topic: FHIR RDF update for HL7
15:47:07 <dbooth> dbooth: Need to do a semi-annual update to the ITS group
15:48:01 <dbooth> Topic: W3C Linked Web Storage WG
15:48:23 <dbooth> eric: partly followup to SOLID work.
15:48:30 <dbooth> ... Loosely chartered
15:49:06 <dbooth> .... I'm co-chair
15:49:18 <dbooth> dbooth: Who are the big drivers?
15:50:07 <dbooth> ericP: Inrupt.  Not IBM yet.  Digital Landern.  HM Government.  INeck  OpenLink software
15:50:37 <dbooth> dbooth: Any submissioni document on the table yet?
15:50:48 <dbooth> ericP: SOLID work would be considered an input.
