PPROC Usage

Last update 02 December 2015

Table of Contents

1. Introduction

As the PPROC ontology is mainly focused to publish data about public contracts, collecting the websites where we can obtain this information from may be usefull. To do so, this webpage presents the actual contracting authorities that are semantically labeling its buyers profile.

We include the list of the classes and properties that are used to label each buyer profile. We believe the set of classes and properties included in this document can be considered as a "dynamic core" of the PPROC ontology, as it presents a view of the real data published by public authorities.

2. Entity usage

The set of classes and properties used in each buyer profile are included in the next table. The first column includes a subset of the properties and classes belonging to PPROC. Each one of the next columns indicates a separate contracting authority using PPROC ontology; we mark each cell with and X if the class/property is being used in its respective dataset.

PCH SPARQL maintenance stops

Provincial Council of Huesca has stopped the maintenance of its SPARQL endpoints. While may still be possible to access its contracts, probably they won't be updated..

Counting the number of properties and classes used in each case we can calculate the percentage of PPROC used. In the case of the Zaragoza Town Hall, we have aproximately 22% of the classes and properties of PPROC being used. As for the Provincial Council of Huesca, we have about 14%.

PCSP extracted contracts

This column refers to a SPARQL endpoint containing data extracted from the Public Sector Contracting Platform of spanish government.

3. SPARQL endpoints

The data can be accessed through SPARQL endpoints:
SPARQL endpoints

Some given SPARQL endpoints with the RDF triples using PPROC may be actually under development, thus could contain incomplete data.
