It seems like the IG pub has a preference for json ...

  • is there an easy fix to this - or should I convert all my extensions to json (I've already done it with a single one and that worked)

strange, i have no problems defining them in xml (e.g. https://github.com/hl7ch/ch-core/blob/master/resources/structuredefinition/ch-ext-ech-10-line.xml)

The really strange part is that I used your project as starting point (@Oliver Egger )

view this post on Zulip Jens Villadsen (Jan 31 2019 at 10:29):

@Oliver Egger - btw - would you happen to know of a service that generates a narrative?

view this post on Zulip Grahame Grieve (Jan 31 2019 at 10:42):

the iG Publisher will generate narrative

view this post on Zulip Grahame Grieve (Jan 31 2019 at 10:45):

the error means that you have a problem with your json format - probably a wrong version issue. Note that the IG publisher is reading at as R4 but the location of the problem suggests that you're using R3

view this post on Zulip Jens Villadsen (Jan 31 2019 at 11:39):

@Grahame Grieve ok, that makes sense. I'm using R3, and that is probably the reason why. Are there flags available to force it to R3 or is it published for different versions?

(Its still a bit weird that is works when I convert the files to json though.)

view this post on Zulip Jens Villadsen (Jan 31 2019 at 11:43):

@Grahame Grieve - could the R3/R4 issue also be the case that I don't see any narrative being generated on my resources?

@Grahame Grieve - ... one more for the grinder:

the narrative thing is not linked to version

you delcare the version you are using

what version have you said?

view this post on Zulip Grahame Grieve (Jan 31 2019 at 12:28):

xml and json behave differently across versions because of how things reflect into the serialization

So ... after having dug into it I've found a way through that sort of works. I'l continue to make my profiles as R3 but serialize them as json. If they are expresssed in json I can continue to have my IG expressed in R4. That seem to work and makes it a bit easier to go to r4 when that time arrives ... this spring
