nomunofu is database server written in GNU Guile that is powered by
WiredTiger ordered key-value store, based on SRFI-167 and SRFI-168.
It allows to store and query triples. The goal is to make it much easier, definitely faster to query as big as possible tuples of three items.
To achieve that goal, the server part of the database is made very simple
and it only knows how to do pattern matching. Also, it is possible to
swap the storage engine to something that is horizontally scalable and resilient.
The idea is to have a thin server and thick client, in order to offload
the database server(s) from heavy computations.
I pushed portable binaries built with gnu guix for amd64 with a small
database file. You can download it with the following command:
$ wget
https://hyper.dev/nomunofu-v0.1.3.tar.gz
The uncompressed directory is 7GB.
Once you have downloaded the tarball, you can do the following cli
dance to run the database server:
$ tar xf nomunofu-v0.1.3.tar.gz && cd nomunofu && ./nomunofu serve 8080
The database will be available on port 8080. Then you can use the
python client to do queries.
Here is example run on a subset of wikidata, that queries for:
instance of (P31) government (Q3624078)
The python code looks like:
In [1]: from nomunofu import Nomunofu
In [2]: from nomunofu import var
In [3]: nomunofu = Nomunofu('
http://localhost:8080');
In [4]: nomunofu.query((var('uid'),
'
http://www.wikidata.org/prop/direct/P31', '
http://www.wikidata.org/entity/Q3624078'), (var('uid'), '
http://www.w3.org/2000/01/rdf-schema#label', var('label')))

As of right now there is less than 10 000 000 triples that were
imported. Blank nodes are included, and only English labels are
imported.
You can grab the source code with the following command:
