Hi Joe,

The 2 dots syntax is used to access the properties and methods of the current object.
You can also use $this to access the current object.

For example, if you have a class called "MyClass" and you have a property called "MyProperty" in that class, you can access the property value by using the following syntax:

User.MyClass Extends EnsLib.BusinessService
{
    Property MyProperty;

    Method MyMethod()
    {
        set ..MyProperty = 10;
        set $this.MyProperty = 10;
    }
}

In your case, you can use the following syntax to access the methods of the EnsLib.File.InboundAdapter class:

User.MyClass Extends EnsLib.BusinessService
{
    Parameter ADAPTER = "EnsLib.File.InboundAdapter";
    Property Adapter = "EnsLib.File.InboundAdapter";

    Method MyMethod()
    {
        do ..Adapter.AdapterMethod()
        do $this.Adapter.AdapterMethod()
    }
}

Hope this helps.

Hi,

You need to fill in some environment variables that allow you to authenticate yourself and therefore connect.

The variables are :

IRISUSERNAME
IRISPASSWORD
IRISNAMESPACE

In a docker file for example :

# environment variables for embedded python
ENV IRISUSERNAME "SuperUser"
ENV IRISPASSWORD "SYS"
ENV IRISNAMESPACE "IRISAPP"

In a shell :

export IRISUSERNAME=SuperUser
export IRISPASSWORD=SYS
export IRISNAMESPACE=IRISAPP

query is the way to go :

import iris

g = iris.gref("^MyGlobal")

# Insert some data
g[1] = "my first line"
g[2] = "my second line"
g[1,"a"] = "my first line with a key"
g[1,"b"] = "my first line with a key"
g[2,"a"] = "my second line with a key"
g[2,"b"] = "my second line with a key"
g[3,"a",1] = "my third line with a key and a subkey"

for (key, value) in g.query():
    print(f"{key} -> {value}")

result :

['1'] -> my first line
['1', 'a'] -> my first line with a key
['1', 'b'] -> my first line with a key
['2'] -> my second line
['2', 'a'] -> my second line with a key
['2', 'b'] -> my second line with a key
['3'] -> None
['3', 'a'] -> None
['3', 'a', '1'] -> my third line with a key and a subkey

I have partially found a solution:

First I create an SQL function with python code :

CREATE FUNCTION sqliknowparser(tText VARCHAR(50000))
    RETURNS VARCHAR(50000)
    LANGUAGE PYTHON
{
    import iknowpy

    engine = iknowpy.iKnowEngine()

    # index some text
    text = tText
    engine.index(text, 'en')

    t_output = ""

    # or make it a little nicer
    for s in engine.m_index['sentences']:
        for e in s['entities']:
            if e['type'] == 'Concept':
                t_output = t_output  + e['index']+ "|"

    return t_output[:-1]
}

Then I use this function in my query :

SELECT 
ID, sqliknowparser(Text) as entities
FROM AA.Goal

Then I "piece" it an use a union query :

SELECT 
ID, $piece(sqliknowparser(Text),'|',1) as entities
FROM AA.Goal 
union
SELECT 
ID, $piece(sqliknowparser(Text),'|',2) as entities
FROM AA.Goal

Any improvement are welcome :)

Another solution can be with SAM :

// Enable Intero metrics for SAM
zw ##class(Ens.Util.Statistics).EnableSAMForNamespace()
zw ##class(Ens.Util.Statistics).EnableSAMIncludeHostLabel()

Since the launch of IRIS, ENSDEMO namespace is gone.

Now to have demo or anything else you have to go with ZPM : https://community.intersystems.com/post/install-zpm-one-line (the package manager).

Check the list here :

https://openexchange.intersystems.com/

If you still want EnsDemo check those githubs :

If you want to discover IRIS for Health with some samples, the best way is to install ZPM (community package manager).
More info here : https://community.intersystems.com/post/install-zpm-one-line

Then, you have access of almost all application in OpenExchange.

Let's have an example with csvgen-ui :
https://openexchange.intersystems.com/package/csvgen-ui

zpm "install csvgen-ui"

In OpenExchange you will find may example about rest API, web app, and so.

For now, it's not possible in pure python, because the select namespace is specified by the environment variable IRISNAMESPACE, and environment variable can't be change in the parent process, I have tried by reloading iris module with no success.

To achieve that, for now, as Robert says, you have to create an helper method in objectscript ... :(

Class Embedded.Utils
{

ClassMethod GetNameSpace() As %Status
{

    Return $namespace
}

ClassMethod SetNameSpace(pNameSpace) As %Status
{
    zn pNameSpace
    Return $namespace
}

}

Python :

import iris

print(iris.cls("Embedded.Utils").GetNameSpace())
try:
    print(iris.cls("Security.Users").Exists("SuperUser"))
except RuntimeError:
    print("Wrong NameSpace")

print(iris.cls("Embedded.Utils").SetNameSpace("%SYS"))
try:
    print(iris.cls("Security.Users").Exists("SuperUser"))
except RuntimeError:
    print("Wrong NameSpace")

If you don't want to create new data on the FHIR protocol, you must use the PUT verb with an ID instead of POST.

PUT creates the resource with the specified ID if the ID does not exist, otherwise it replaces the pre-existing data.

POST always creates a new resource with a new ID, that's why the ID is not mandatory when POSTing.

For automatic transformations from HL7/CDA to FHIR, there is the possibility to define the ID for some resources and thus to avoid duplication.

Below is an example of code to transform an HL7 payload to SDA by specifying the ID of the patient in order to avoid duplicating this resource, after that you can transform this SDA to FHIR with no duplication of patient.

/// This is a custom business process that transforms an HL7 message to SDA format (an internal healthcare data format for InterSystems IRIS for Health).
/// To use this class, add a business process with this class to the production and configure the target. The default target will send the SDA to a component
/// that converts the data to FHIR.
/// 
Class FHIRDemo.HL7TransformProcess Extends Ens.BusinessProcess [ ClassType = persistent ]
{

Parameter SETTINGS = "TargetConfigName:Basic:selector?context={Ens.ContextSearch/ProductionItems?targets=1&productionName=@productionId},TransformFile:Basic";

Property TargetConfigName As Ens.DataType.ConfigName [ InitialExpression = "HS.FHIR.DTL.Util.HC.SDA3.FHIR.Process" ];

/// Transforms an HL7 message to SDA, an internal healthcare format for InterSystems IRIS for Health.
Method OnRequest(pRequest As EnsLib.HL7.Message, Output pResponse As Ens.Response) As %Status
{
    set tSC = $$$OK
    try {
        $$$ThrowOnError(##class(HS.Gateway.HL7.HL7ToSDA3).GetSDA(pRequest,.tSDA))
        $$$LOGINFO(tSDA.Read())

        Set tQuickStream = ##class(HS.SDA3.QuickStream).%New()
        $$$ThrowOnError(tQuickStream.CopyFrom(tSDA))

        Set tResponse = ##class(HS.Message.XMLMessage).%New()
        Do tResponse.AdditionalInfo.SetAt(tQuickStream.%Id(),"QuickStreamId")
        Do tResponse.AdditionalInfo.SetAt($P(pRequest.GetValueAt("PID:3:1"),"^"),"PatientResourceId")

        Set tSC = ..SendRequestSync(..TargetConfigName,tResponse,.pResponse)
    } catch ex {
        set tSC = ex.AsStatus()
    }
    quit tSC
}
