I have an application with maps that render and edit geographic data in a some layers using KML - geo data represented into XML file with layers, polygnons, points and metadata associated with it. Some maps are in GeoJSON too.

Is it DocDB the better option?

Just for the info, few years ago, on Moscow's hackathon was a project SpatialIndex. Related article

The format is stable, use XML tools for data import/export into persistent classes.

@Yuri Marx :
if you have the schema as XSD at hands
All you need to do is to open the XML wizard in IRIS Studio and it generates the whole packages for you

>>>

I used it rather intensive and a pack of 100+ classes from 1 XSD was no problem

If it was me I'd use the persistent DOM of QEWD-JSdb

https://github.com/robtweed/qewd-jsdb/blob/master/DOM.md

QEWD includes access to this.

The KML spec is a complex XML schema. See:

Into Postgresql it has PostGIS, because this complexity, in IRIS I need only use this XML import utility?

@Dmitry Maslennikov
Is this also supported by VSCode?
