How to extract DNG baseline information (such as baseline name, creation time and created by) for all the created baselines using RPE?

There's no public supported API that I'm aware of that does this.

You can try something like:
https://<server>/rm/queryvvc/configurationsforcomponent?component=https://<server>/rm/rm-projects/<projectID>/components/<componentID>&configurationtype=snapshot

Before you say that this isn't opted in to CM, I was able to do this with a project not in CM. I got the componentID from the URL in the project area when I went to the module.

This returned JSON that gave me a list of all the baselines in the project!

There may be other ways but this post has an example of the RM discovery sequence which includes finding the configurations in a component - https://jazz.net/forum/questions/266334/dng-oslcfetch-components-from-project-area/266667 which I guess you could do from RPE javascript.

If you already have a configuration url, GET it (with headers OSLC-Core-Version: 2.0 and Accept: application/rdf+xml) is a quick way to find the component url in a tag like

    <oslc_config:component rdf:resource="https://jazz.ibm.com:9443/rm/cm/component/_DaJb8LFXEe-j4_rM2KKkmw"/>

this is shown in the answer I linked to.

As per that answer, GET the component url (same headers) and the configurations URL is in a tag like:

    <oslc_config:configurations rdf:resource="https://jazz.ibm.com:9443/rm/cm/component/_NUHKsLFXEe-j4_rM2KKkmw/configurations"/>

That gives you the url of all configs in the component in a series of rdfs:member tags - follow those to get the config name etc.
