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]
