About CRA-ABP

The Agricultural Research Council – Research Centre for Agrobiology and Pedology (CRA-ABP), has for many years developed soil survey, mapping, and informatization methodologies. Several thousands of soil observations have been stored on a Ms Access database. This Information System was the starting point to develop the Vocabularies for Soil Data as Linked Data

Some history: Guidelines of the methods of soil survey and data informatization (Italian)

On 2007 the CRA-ABP published the ”Linee guida dei metodi di rilevamento e informatizzazione dei dati pedologici” (Guidelines of the methods of soil survey and data informatization) a volume with an attached CD-rom “CNCP 3.0, Database for soil observations and pedological units storing, correlating and geoexploring”.

The CNCP 3.0 software

The software was developed according to the indication of the European Soil Bureau Handbook (Finke et al., 1999) and the ”Metodologie pedologiche” project (Costantini and D'Antonio, 2001).

Was adopted as soil information system by several regional soil services.

Can be considered as the Italian standard for soil database architecture.

About soil international standards

Technical Committee ISO/TC 190, Soil quality, Subcommittee SC 1, Evaluation of criteria, terminology and codification. ISO 11074:2005. Soil quality – Vocabulary

Technical Committee ISO/TC 190, Soil quality, Subcommittee SC 1, Evaluation of criteria, terminology and codification. ISO 28258:2013(en) Soil quality — Digital exchange of soil-related data

The adoption of soil international standards was developed to enhance interoperability of data for uses related to agriculture, agro-industry, food, forestry, natural and geological science.



agINFRA work to publish new LOD vocabularies for soil data

In the European legislation, INSPIRE is the reference standard for soil data organization and dissemination among European citizens and institutions.

Since agINFRA is an EC project, the partners agreed that INSPIRE should be adopted as the starting point for a LOD metadata vocabulary for soil data.

INSPIRE is a good starting point for both:An RDF metadata vocabulary, as it defines

entities and attributes / relationships;The identification of KOSs that need to be

published, as it defines “registers” of values.

1° step: from ISIS (Desktop-GIS) to SISI (Web-GIS)

In order to allow online data consultation, the Ms Access database was converted to a PostgreSQL database according to INSPIRE soil standards (Schentz et al. 2012).

Online publication of the SISI application was possible with the support of the agINFRA e-infrastructure project.

The Cloud infrastructure was chose to ensure higher performances, more fault-tolerant, and secure design.

Conclusions

The adoption of LOD technologies are expected to improve the interoperability of soil data.

Providing tools and methodologies for enabling the soil data-related vocabularies as linked data, the agINFRA project is enhancing the interoperability not only between soil data sources but also between soil data sources and other types of data sources.

The publication of additional soil-related INSPIRE compliant vocabularies will be a big step forward and will represent one of the novel contributions that agINFRA makes to the agricultural data management community.
