Introducing gPrime

gPrime is a new browser-based genealogy program descended from Gramps, and this is a new blog to describe and discuss it. gPrime is designed to become a modern, easy-to-use genealogy program for the 21st century. Specifically it is designed:

  • for collaboration – multi-user ready
  • powerful, easy to use search – select exactly what you want to see with a Google-like text search
  • with security in mind, to keep your information safe and private
  • for very large family trees
  • for future generations
  • for long term and modern technologies – robust database and storage formats
  • for the modern genealogist, including flexible gender categories
  • browser-based interface – works locally, on a server, and on mobile platforms such as Android, iPhones, iPads, etc.

gPrime uses the JSON format for storing all data. This makes your data safer than other programs (Gramps uses “pickled” data which is a security issue, and may not be available to decode for future generations as it has changed over time). gPrime uses modern SQL databases (sqlite, MySQL, and PostgreSQL), although it does not use relational structures.

gPrime is designed so that you can select a subset of any genealogical data based on any criteria. For example, if you want to search common fields, you just enter the information, selected by commas. For example, entering this in the search field:

Smith, Amber

would search common fields for “Smith” and “Amber” and show those that have both. You can also specific which fields to search, like this:

surname=Smith, given=Amber

Finally, you can search for any specific bit of information, if you know how that is specified in the data. For example, imagine that you wanted to find all people who have a father named “Edwin”, then you could enter:

parent_family_list.father_handle.primary_name.first_name=Edwin%

That is a little complicated, but the point is that you do not need to wait for a programmer to add a special filter to search for something, nor do you need a complex set of combinations of filters to select items based on simple values. We’ll try to make this easier, too, over time.

The goal is to make gPrime complete by July 2017, but it is already somewhat usable. See the github software repository for instructions. We’ll cover more details about how to install, test, and help.

    1. Great question! The design of the database backend can be swapped out fairly easily if we want to allow MongoDB, or some as yet not created database engine.

      But I decided that for now we want to support as many operating systems in as robust a fashion as possible. So, we went with the best choice: sqlite. But rather than targeting just sqlite, it is written in abstract SQL (DB-API 2.0) so other SQL backends can also be used.

  1. Thank you, I’ll have a go at it, though it will likely be n fits and starts depending on how well I make out and what else needs attention 🙂

  2. Being quite new to this sort of thing, now that I have Anaconda installed,
    what sort of interface/environment would you recommend to start with?
    conda/Navigator/Jupyter/IP/Spyder?? Others?

    1. You don’t need any development tools to just run a local copy for testing. If you want to look/edit the code, then Jupyter, IPython, or Spyder will work fine. I use emacs.

      This is fine for now.

  3. Thank you, Doug
    Right now I have installed Anaconda and gprime using pip, as explained on the github page.
    I have gprime in my AppData\Roaming\Python directories – I am running Win 10 – but that is where I am stuck. I have tried to continue on from ‘Getting Started’, but have not found the proper place or incantations yet.
    In the Anaconda prompt window, I have:
    (C:\Users\Arnold\Anaconda3) C:\Users\Arnold>python
    Python 3.5.2 |Anaconda custom (64-bit)| (default, Jul 5 2016, 11:41:13) [MSC v.1900 64 bit (AMD64)] on win32
    Type “help”, “copyright”, “credits” or “license” for more information.
    >>>quit()
    So I know I have python available.
    Where and how do I start a test server as a first effort 🙂
    gprime code is present in several places:
    C:\Users\Arnold\AppData\Roaming\Python\Python35\site-packages\gprime\
    C:\Users\Arnold\AppData\Roaming\Python\share\gprime
    c:\Users\Arnold\AppData\Roaming\Python\Python35\Scripts\gprime.exe
    I have tried a few things, but no success and lots of different error messages 😦

      1. In an admin DOS box, I cd’d to the scripts dir and tried:
        ——————————-

        I was hoping that all those extra libs would be part of the installation.
        Tried the same in an Anaconda prompt, with the same results

    though a directory ‘FamilyTree is created in the scripts dir, so I have made some progress.
    Next I made sure both Scripts and site-packages were not write protected, but no difference.

    1. Two things:

      1) Looks like you are running older code. Try pip install gprime -U

      2) I think the proper way to specify the filename is:


      gprime.exe --site-dir="d:\\FamilyTree" --create="My Family Tree"

      or


      gprime.exe --site-dir="d:/FamilyTree" --create="My Family Tree"

      1. Sometimes – my last post was somewhat lengthy – possibly that was the issue.
        Basically, I had to move to another machine and downloading the latest gprime does not give me a gprime.exe.

        running the commands as given, without the ‘.exe’, gives me:

  6. Finally, after re-installing the latest Anaconda 4.3.0 – updating some of the packages in the previous 4.2 version seemed to kill things – I was able to follow your instructions and use the gprime.exe to actually install and set up a demo installation.
    Thank you for work on gPrime & your help in getting me this far.

  8. The problem with PyICU is that it tries to compile the code, and so you need more tools on Windows.

    You might be able work around this for now by installing gprime without dependencies, and then installing just the ones that you need:

    pip install gprime –no-deps
    pip install tornado
