agINFRA work on germplasm and soil Linked Data by Luca Matteus, Giovanni L’Abate and Maria Antonietta Polombi
0 likes864 views
The document discusses the integration of agricultural data from various sources through the use of linked open data principles, addressing challenges in data formats and standards. It outlines a multi-step process for converting and publishing germplasm and soil data as RDF, which includes data mapping, linking to other resources, and building applications that can leverage SPARQL queries. Future work aims to enhance interlinking of datasets and integration with external portals.

Data coming from different sources is hard to integrate because: – Data is published using different formats (CSV, Excel, XML, JSON) – Data is described using different standards (vocabularies, ontologies, taxonomies) – Data is not linked together Linked Open Data for germplasm and soil Luca Matteis 20/09/2014

Linked Data provides the principles that enable smarter integration of data: – Publish your data as RDF (JSON-LD, Turtle, RDFa, etc...) – Resources should be identified using resolvable HTTP URIs – Link your resources to other RDF resources using HTTP URIs Linked Open Data for germplasm and soil Luca Matteis 20/09/2014
