MatWare is a tool for constructing domain-specific warehouses by aggregating semantic data. The main objective is to tackle the need for having integrated sets of facts regarding a particular domain.

Features top

MatWare is capable to:

  • download data from remote sources
  • create Virtuoso repositories
  • ingest the data to the warehouse
  • apply the necessary transformation rules to the data
  • create sameAs links between the entities of the different sources
  • create the inference ruleset
  • refresh the repository
  • compute several quality metrics

  • MarineTLO-based Warehouse

    This warehouse integrates marine-related information coming from 5 different sources (FishBase, WoRMS, ECOSCOPE, FLOD, DBpedia) and allows answering sophisticated queries that cannot be answered by an individual source. Currently, it contains information for about 40,000 marine species, while the total triples are more about 4 millions.

    The MarineTLO-based Warehouse is currently used in the context of the iMarine project, and can be accessed through the iMarine portal. A document describing how to access it can be found here.

    Related documents:

    • Competency queries (version 3) used for building the MarineTLO-based Warehouse (a list of queries provided by the community that are useful for the community at hand).
    • SILK rules (a set of rules that were created for automatically linking entities from different sources using sameAs links)

How to exploit it top
  • For building a domain specific warehouse (accessible through a SPARQL endpoint) which will allow one or more applications to take advantage of it.
  • For publishing Linked Data related to a domain.
