I'm still in the phase of finding out, if there might already be all the tools available, but it seems, I won't get around writing at least some code for it.

I'll probably start extending an existing AP implementation, or using a library, instead of writing everything from scratch. But nothing is set in stone yet. Do you have any suggestions?

Are you thinking of coding something for this?

Regarding:
"but also e.g. "I have a new job""

You could either do that with a custom Object type.

Or, using an existing Object type — such as Note, or one of the others.

Yes, as a starting point, that's what I thought as well. Just if there already would have been sinething, I wouldn't try and reinvent the wheel.

One issue with blindly adopting #h-resume is, that in an #ActivityPub context, you usually don't just state "here is my resume", but also e.g. "I have a new job", which then is an update to your resume. A use case, that never existed for h-resume.

So there's still work to do. But it's definitively a good start.

You could, for example, use h-resume with ActivityPub.

ActivityPub is, in some ways, just another JSON-LD name-space.

Just use h-resume as another JSON-LD name-space along with ActivityPub.
