Open Source
We are software passionates and we spend a relevant amount of time in creating, improving and contributing to open-source software. Open-source software forms the basis of our solutions: proven tools and frameworks available nowadays, without any license or download fee.
Here’s a list of public repositories we contributed to / created. We keep working on them as part of our daily Research & Development effort.
SolRDF: Apache Solr + RDF
SolRDF (i.e. Solr + RDF) is a set of Apache Solr extensions for managing (index and search) RDF data.
The main purpose of SolRDF is to create an open-source, scalable, fulltext-enabled triple store that provides SPARQL 1.1 protocol and fulltext search capabilities.

Apache Solr Composite Request Handler
An Apache Solr component that allows to create a search workflow on top of a single search request.
Each handler in the chain controls the transition to the next handler.
Apache Solr Quantity Detection Plugin
The idea behind this Apache Solr plugin is the following: it detects the quantities (i.e. the amounts and the corresponding units) in a user query. Then, once quantities are isolated from the other query terms, they will be used for boosting up products “matching” those quantities.
