Re: openEHR-technical Digest, Vol 80, Issue 12
Hi all, It's been a while since I've seen it but I think Pablo Pazos has some quite good work for that topic on EHRServer, at least for subsumption [ https://ppazos.github.io/cabolabs-ehrserver/ mentions "Support of SNOMED CT Expressions on openEHR queries (simplifies complex queries)"]. There is also a demonstration video on YouTube. With regards to binding to the model, though, things might be tricky. Cheers, Ricardo Gonçalves.

Re: [Troll] Terminology bindings ... again
Hi everyone, After following this thread for a few days, I decided to jump in with my two cents because either things got too rethorical while looking for a state of art solution matching particular experiences or I'm missing the point more than I should. Historically, statistical classifications such as ICD10 and ICPC2 have been used in health [informatics] (even on handwritten forms, for ranking purposes). They are as easy to understand/use as their taxonomy allows them to be, but the added value is limited to such scope. They are also pretty close to the way generic binding is currently handled (matching and validating code/term pairs). SNOMED CT is not perfect and is not simple, but we cannot demand to oversimplify such a complex matter. It encompasses a lot of work to achieve a formal ontology that allows both people and machines to understand | fracture | : | finding site | = | ankle | in multiple idioms. I think it's quite effective as a "language" (yet not trivial, but again, to get the mass to accelerate, some force must be applied). In spite of the meaning on it's own, that expression can also be easily computed to a preecoordinated concept (if one exists and is required, e.g. | fracture of ankle |) or to a set of concepts that match the described meaning (even if you don't know all of them beforehand, but just some basic/critical defining attributes/relationships) so the professional can get filtered suggestions (supported by a capable health application/system, just like they already do with statistical classifciations/coding systems). It also allows you to query/retrieve the same data point despite being coded as (| fracture | : | finding site | = | ankle |) or | fracture of ankle |. Actually, it allows even more due to customization and localization. I too want to look at the the future and picture a state of art component and hopefully a [health] technological utopia, but a lot of work led us to what is currently available. Are we taking that to try/improve things and get somewhere? Are we holding back until something more mature, more usable, more future-alike comes up? Which path is more likely to bring us closer to the goal? Best regards, Ricardo Gonçalves.

If what you want to do is what has been done since 1980, that's to say fill forms inside a care place and exchange it with other care places, I guess that Snomed CT is the proper component. Since it was born a coding system, you can create complicated meta-concepts in a single code (of course, it means you will have to find your own subset inside an always expanding universe, but ease comes with a price) and it is very convenient to fill the good old set of attribute?value pairs. On the contrary, if you estimate that a modern approach would be to tell and organize a patient's journey, you have to exhibit more modern structures because in order to "tell something", you need not only a terminology (say a vocabulary) but also a grammar. A proper grammar (at least the one I use) can be a "dependency grammar" in the form of a graph or trees. Now that you can tell elaborated things using a vocabulary (the ontology) and a grammar (the graph of trees), the "agglutinating" structure of Snomed rapidly sucks. Because now that "fracture of the left ankle"
Re: openEHR-technical Digest, Vol 72, Issue 4
On the "putting together a web frontend and a Java backend" topic, it may be interesting to look at Vaadin, which is an open source framework to build web applications using Java (you code everything in Java, an equivalent GUI is generated and all behavior that comes from user interaction is actually triggered on the backend through a protocol like RPC; pretty much like the old GWT but smarter and with less boilerplate code). They also have a dev preview on something called Flow, which is supposed to give a Java backend direct access to the DOM, somewhat similar to real-time server-side rendering but with an optimised communication protcol instead (no need to care about APIs, REST, whatever). Anyway, since we're already on a Java ecosystem, those may be easier than modeling APIs and adopting JavaScript frameworks that may or may not be alive tomorrow. Att., Ricardo Gonçalves.

Just that JS/TS are the languages that seem to be popular for web app development these days, and Java for the back-end. The connection between front and back-end that people seem to prefer these days is REST APIs, which both Java and JS can do easily enough. - thomas On 03/02/2018 07:56, Peter Gummer wrote: > On 1 Feb 2018, at 05:13, Thomas Beale > > wrote: >> >> ...
