Smart Data Management Platform

This project contains all needed for setting up and update a knowledge base ready to be used by the inps.g0v.it application.

The knowledge base is built around the g0v application profile and LODMAP Bubble Graph Ontology:

• the g0v-fr application profile is used to describe the semantic of a financial report
• the Bubble Graph Ontology is used to describe the graphical objects that reprensent financial report components

The data ingestion process is managed by the LinkedData.Center SDaaS platform (community edition).

knowledge base build process:

• edit local rdf files in the data directory providing static metadata (titles, taxonomies, welcome links, etc. etc.)
• develop the gateways for transforming raw data about financial report in linked data according the g0v application profile. See gateways doc.
• write axioms and rules to cleanup financial data.
• write axioms and rules to link financial data to the graphical objects.
• edit the build script that drives the whole data ingestion process.
• run sdaas

debugging the build script

the test of the build script requires the sdaas-ce container.

docker run --rm -ti -v $PWD/gateways:/app composer install --no-dev
docker run -d -p 9999:8080 -v $PWD/.:/workspace --name kb linkeddatacenter/sdaas-ce
docker exec -ti kb bash
apk --no-cache add php7-iconv
sdaas --debug -f build.sdaas --reboot
exit
docker rm -f kb

logs info and debug traces will be created in .cache directory

Access the admin workbench pointing browser to http://localhost:9999/sdaas

publishing the knowledge base

You can pack data and services with :

docker build . -t sdaas
docker run -d -p 8889:8080 --name datastore sdaas

The resulting container will provide a readonly distribution of the whole knowlede base in a stand-alone graph database with sparql interface.

Directory structure

• the build.sdaas file is a script to populate the knowledge base from scratch. It requires sdaas platform community edition 2.0+
• the axioms directory contains rules to be processed during reasoning windows.
• the data directory contains local data files
• the data/src directory contains some helper that were used to produce some ttl files.
• the gateways directory contains the code to transform raw data in linked data
• the .cache temporary directory that contains logs and debugging info. Not saved in repo.

Credits and license

• the dockerfile reuse Docker Blazegraph
• the sdaas platform is derived from LinkedData.Center SDaas Product and licensed with CC-by-nd-nc by LinkedData.Center to g0v community
