[Note] eXistDB in docker and XML databases

XML is heavier than JSON, but schema in JSON is non-standard and still new.  Thus XML is more suitable when strict schema is needed.
Two open source XML DB I experimented a while back:

• BaseX
• https://basex.org/
• https://en.wikipedia.org/wiki/BaseX
• eXistDB
• http://www.exist-db.org/
• https://en.wikipedia.org/wiki/EXist

Both are Java based.

BaseX

This is available in SNAP, comes with Swing UI.

eXistDB

There is a docker image, https://hub.docker.com/r/existdb/existdb

$ docker pull existdb/existdb:latest

I have Tomcat using 8080 locally, thus using 8090 instead:

$ docker run --name existdb -p 8090:8080 -p 8443:8443 -d existdb/existdb:latest
$ docker logs -f existdb

Open with browser, http://localhost:8090/
