I’m working on XML Digital Signature in InterSystems IRIS using %XML.Security.Signature

I start with an XML document that is created by parsing an input XML string, and I want to digitally sign this document using an X509 certificate.

I have a Photo that is stored as an VARBINARY within MS SQL. I would like to Select the data into a EnsLib.SQL.Snapshot, is that possible? I would take it out of the Snapshot and send it to a %Stream so it can be written out to a file.

I'm generating a XML (Enlib.EDI.XML.Document) using a Subtransformation within a DTL. Writing this XML-Document to the filesystem works good, but in the XML-File is missing the header line (<?xml version=1.0 encoding=UTF-8?>):

What do I have to do to get the header in my XML-File?

Any help is appreciated.

Can the IRIS SQL engine be extended with custom optimization rules (e.g., prioritizing certain indices or join orders)? If not, is there a supported way to influence cost models?

For geographically distributed nodes using async mirroring or ECP, how can I detect and resolve data conflicts manually (custom logic) while maintaining eventual consistency?

Hi,
Our production FHIR server is populated by several processes from several sources,
some of those sources send test data or wrong data (by mistake or as part of an integration test),
the data is consumed by our BI every 15 minutes.
when I mark a resource as test (using meta security) BI knows to update it on their system.
everything is fine up to here (except that there is test data in Prod)
my problem is that if someone send the same patient again it will recreate the patient without the security tag.
any thoughts?
