missing email, prototype/addon
>> If interested in further details, please drop an email.
Mea culpa. I have forgotten or never quite learned wiki protocols. I had guessed or expected the wiki provided my email address to interested parties. I see that is not the case. I have noticed few or no user email addresses. I therefore modified my 'bio' to invite 'talk' to me.
RE: prototype(s) sound interesting
Which of my projects do you find interesting? I am little interested in the additional work developing a private project to an addon without additional interest. You are the first to show an interest.
At this point my prototype projects are a mix of python 2.7 migrating to 3.8 and 3.8. Prototype for me means little or no error checking and no gui. If this is an acceptable start to a github addon, perhaps with a little dusting off, I would be happy to upload it.
As I recall, the "Ancestor Migration" is basically a script to apply an XSLT to extract the migration information from an earlier GRAMPS XML format. The XSLT was fun because of its requirement to be recursive. I had originally expected to generate a Historical Events Markup Language (HEML) file but found QGIS did all the work for me. The extracted data is an input to QGIS that generates a moving time line of the migration on a map. At this point I have yet to connect the events and reduce the cluttering on the map. Perhaps OpenLayers with map zoom controls. As addon master, if you are still interested, should I create an appropriate github entry and upload the video?
From my Repository / Source / Citation reporting project it is more a tool for me to organize and confirm better documentation. I can well imagine it might be helpful to others.
