15:05:35 <dbooth> Meeting: FHIR RDF
15:05:38 <dbooth> Chair: David Booth
15:05:41 <dbooth> Topic: DICOM
15:06:17 <dbooth> erich: Virtuoso can key off of the datatype string for polygons, so we don't need to use an RDF list.
15:07:35 <dbooth> erich: Support for geosparql is the most of what we can expect for support.
15:07:56 <dbooth> ... There's an add-on for jena tdb also.
15:08:33 <dbooth> ... I use this well-known string approach along with intersecting wth hilbert.
15:09:14 <dbooth> ... Choice of well-known text means there's already a lot of support.
15:09:38 <dbooth> detlef: Oracle claims support and also StarDog.
15:09:53 <dbooth> erich: GeoSparql work is still going on.
15:10:12 <dbooth> ... Seems like the best choice to me.
15:10:53 <dbooth> ... Want to try enumerating which tags contain polygon data, to convert from binary to well-known text.
15:11:44 <dbooth> ... It's a custom datatype that says it's formatted as a well-known text.
15:12:21 <dbooth> ... Spaitla indexing question will arise if we bring it to the DICOM group.  They are now looking at that issue.
15:12:36 <dbooth> s/Spaitla/Spatial/
15:13:29 <dbooth> erich: Planning on working on that next.
15:13:51 <dbooth> ... David Clooney said not to use dicom namespace, without a process.
15:14:38 <dbooth> detlef: Sounds like a good approach.  Could go forward w that.
15:14:59 <dbooth> ... Need to convince DICOM group.
15:15:22 <dbooth> ... But they're looking for an abstract data rep -- could put arbitrary things in.
15:15:45 <dbooth> ... Electrocardiogram is a point also.
15:16:15 <dbooth> ... I think that works.
15:16:24 <dbooth> erich: You can go backward also.
15:17:02 <dbooth> detlef: Would be amazing to be able to find max X in a sparql query.
15:18:47 <dbooth> erich: Re FHIR group, they want to RDF-ize some DICOM terms.  Why, if you can just use DICOM text strings?
15:19:26 <dbooth> ACTION:  DBooth to put Erich in touch w Dave Beckett.
15:22:25 <dbooth> Topic: Errors in  FHIR RDF example
15:23:55 <dbooth> ACTION: Jim to compare FHIR RDF diffs  to see if Tim Prudhomme's PRs are good to merge
15:25:45 <dbooth> jim: SPARQL CDT proposal from Amazon was submitted to the SPARQL group.
15:26:02 <dbooth> https://github.com/w3c/sparql-dev/pull/200#issuecomment-2316298150
15:26:19 <dbooth> jim: They have a fork of jena with it implemented.
