HL7 Section to JSON

Hi all,

I'm trying to convert a HL7 section to a XML or JSON string.

We need to save the content of PID section into a SQL Column, therefore we need to convert it into a XML o JSON string

is there any easy way to convert it?

I've tried to convert it directly into a DTL, but all my attempts have been unsuccessful

Best regards,

Francisco Lopez

Hi There,

I'm fairly new to ObjectScript/Ensemble and I'm sure I may be fundamentally misunderstanding how the %JSONImport/%JSONExport and XDATA mapping work and I was hoping you good folks could help me out. I'm essentially trying to create an object that I can use to translate from one JSON schema to another.

First my class:

Hi there,

I'm passing a JSON object to the server as such:

{"key":"value","key":"value","key":"value"}

From the client:

- Build object

object=JSON.stringify(object)

-pass to server side method as %String

On the server:

s object={}.FromJSON(object)

Instead of getting something like

object=<OBJECT REFERENCE>[2@%Library.DynamicObject]

I get

object="991@%Library.DynamicObject"

I can't access that object using %Get as if says invalid OREF.

MAXSTRING limit issue

MAXSTRING (longstring) is enabled.

We have a Class containing a property definition

Property SettingsJSON As %Text(MAXLEN = 3600000)

The property is used for storing a string of JSON data however in some cases we get a Cache error: %SaveData error when trying to save a string of JSON a lot less than maximum "allowed" length, any ideas anyone?

Time handling and Json

I am having trouble formatting %Time to a JSON format. I have tried configuring the parameter "FORMAT" of my property but that didn't work. For some reason, it keeps putting a Z and the end of the time.

Property:

Property TimeCollected As %Time(FORMAT = "2");

Hi Community,

I have json equivalent persistent object in pjsonObj variable. Final JSON example below.

{
"Document": {
"FileExtension": "pdf",
"FileContent": "JVBERi0xLjUNCiW1tbW1DQo...(very large bsae64 string)"
}
}

Here FileContent field in json will contain converted base64 string of very large pdf(10pages). I need to submit this json as a payload to REST endpoint.

below code is working fine.

I have defined a class with a dynamic object property:

My class

The issue I encounter is that if a length of a serialized json property is more than 3641144 symbols, the object fails to save with the following error (either MAXSTRING or STRINGSTACK):

Length: 100 Result: OK
Length: 3641143 Result: OK
Length: 3641144 Result: OK
Length: 3641145 Result: ERROR #5002: ObjectScript error: <MAXSTRING>%GetSerial+1^%Library.DynamicAbstractObject.1
Length: 7282288 Result: ERROR #5002: ObjectScript error: <STRINGSTACK>%GetSerial+1^%Library.DynamicAbstractObject.1

Is there a workaround? I need to store moderately large jsons (10-15 Mb) and dynamic object properties allow for a very convenient access.

$ZSTORAGE is set to -1.

FHIR Bulk Data and ndjson

Hi all,

I am testing asynchronous Bulk Data retrieve with a large EHR vendor. When I retrieve the bulk data, they are returning ndjson (CONTENT-TYPE of "application/fhir+ndjson; charset=utf-8"). If I attempt to process that content using JSON functions - I get

ERROR #5035: General exception Name 'Parsing error' Code '3' Data ''

For example, the following generates the error

s objArray={}.%FromJSON(quickStreamOut)

The error makes sense in that ndjson is not a valid json format (I assume at least).

JSON - NULL Properties

So I've been reviewing a lot of questions posted in the InterSystems community regarding NULL properties in JSON. I've also been reviewing the JSON documentation. None of these things have been able to help me so far.

1. We don't seem to have the %JSON.Adaptor class available for us to use in our system.

2. I'm not really confident enough to create JSON Type classes or backporting code, etc.

I have an issue where a Windows Reserved word, in my case CON, is causing an error when used as part of a JSON Get operation. In this case CON is the user identifier (the full identifier is CON.SURNAME) of a person and I am trying to read the employee record using a web service provided by the payroll system.

Is there a way I can get around this, some sort of encoding that would enable the inclusion of this identifier. I can't just change the identifier has it is used extensively across systems.

Hi all, I am new to IS Objectscript and I would appreciate some assistance regarding this.

I am trying to find out how to count the number of elements within a dynamic abstract object and I am having some trouble using the size method.

Here is the code below:

The key value pairs are originally in JSON and I would have converted it in to an object for use.

I'm trying to set up VS Code for ObjectScript using the instructions found here. I've got both Cache 2018.1.2.309.0 and IRIS 2020.1.0.215.0. When I try to connect to either one of them the connection fails, and I get a notification in the bottom right corner that says "Unexpected token < in JSON at position 0". I've checked the JSON settings file that VS Code uses, and they're fine and formatted properly. All of the settings I've entered are correct.

Hello,

I am trying to find out if it is possible to decode the Azure access token in IRIS. Has anyone ever tried this before? I need to decode the token to extract the "Scope" details in order to verify the scope to make sure client is permitted to do the request they have done.

If you could point me to any information, that'd be great.

Thank you.
