Dear all:
I am glad to announce the official release of BauDataWeb, the European
building and construction materials database for the Semantic Web:
URI: http://semantic.eurobau.com/
With this project, we expose a major dataset reflecting the European
building and construction materials market on the basis of the
GoodRelations Web Vocabulary for E-Commerce. This allows for the
fine-grained search for products, suppliers, and warehouses for any
building-related sourcing need.
BauDataWeb is one of the densest and richest public datasets for a
well-defined vertical business sector that is available on the Semantic
Web. It covers a major share of the European market for construction and
building materials.
Key distinctions from other datasets are:
1. The market for building materials shows a very high item specificity,
which makes it very interesting for new types of search.
2. Transportation costs for building materials are usually very
significant, which makes the distance from the warehouse to the point of
consumption a critical dimension of search.
3. A large part of the items includes a rich, machine-readable
description of product features using the FreeClassOWL ontology.
We expect that the data can be very well combined with other related
datasets on the Web of Linked Data, e.g.
* dbPedia information about population or transportation infrastructure,
* governmental information, or
* real estate offers.
Features
========
* Over 60 million triples of real business data with a high domain
density
* Fully GoodRelations-compliant
* Fully W3C-compliant
* Geo data for warehouse locations
* FreeClassOWL product classes and properties for a majority of the
products
Components
==========
1. Dataset: The full data is available in RDF. The data consists of ca.
1.5 million individual RDF/XML files plus a few large data dumps in
N-Triples syntax that simplify the crawling of all data at once. For
fetching the dataset, please use the sitemap at
http://semantic.eurobau.com/sitemap.xml.
2. FreeClassOWL: A GoodRelations-compliant ontology for describing
construction and building materials and services
* HTML: http://www.freeclass.eu/freeclass_v1.html
* OWL in RDF/XML: http://www.freeclass.eu/freeclass_v1.owl
3. The Eurobau Utility Ontology, which defines a few extensions to
GoodRelations for the particular vertical domain
* OWL in RDF/XML: http://semantic.eurobau.com/eurobau-utility.owl
(no other representation available at the moment)
4. A (simple) demo application that demonstrates queries combining
product features and warehouse distance
* http://www.ebusiness-unibw.org/tools/freeclass-search/
SPARQL Access
=============
Currently, the data is available for SPARQL queries via the OpenLink
Software Virtuoso repositories at
* http://lod.openlinksw.com/sparql and
* http://linkeddata.uriburner.com/sparql
Statistics
==========
* 81 Manufacturers / Brands
* 19 Resellers
* 183 Warehouse locations in Austria
* 56.360 Product types (including variants)
* 1.783.798 Offerings
* 95 % of the product models include rich FreeClassOWL descriptions,
e.g. class membership and properties

===============
BauDataWeb is a joint project by inndata Datentechnik GmbH and the
E-Business & Web Science Research Group at Universität der Bundeswehr
München. The data conversion and implementation was carried out by
Andreas Radinger and Martin Hepp at the E-Business & Web Science
Research Group at the Universität der Bundeswehr München, Germany. The
underlying relational database has been designed by Otto Handle and is
being maintained and operated by inndata Datentechnik GmbH.
The work on BauDataWeb was partially funded by the Austrian FFG under
the project grant "icontent.document" (grant no. 819773). Thanks go also
to Kingsley Idehen from OpenLink Software for hosting the data.
Best wishes
Martin Hepp
