# Phenological Stages

This repository is dedicated to the construction of  semantic resources (RDF dataset and OWL ontologies) that represent plant phenological development stages for agricultural practices. This work is part of the ANR D2KAB project. 

BBCH-based Plant Phenological Description Ontology (ppdo) is an ontology that extends skos model to store bbch phenological scales and other scales.  ppdo ontology contains already two BBCH scales:
*  the BBCH general scale that could be used for any crop that do not have an BBCH individual scale.
*  the BBCH global scale, a new scale created for the purpose of D2KAB project. This scale contains all the phenological stages from the BBCH general scale, the BBCH inidvidual scale of grapevine and the BBCH individual scale of cereals. 
More information about this ontology and associated datasets are available on http://ontology.irstea.fr/pmwiki.php/Site/Ppdo

ppdo metadata are  published on the web at the uri http://ontology.inrae.fr/ppdo
ppdo is also described in data. inrae https://doi.org/10.15454/TIMQHW

A sparql end point to query ppdo and related datasets are available at http://ontology.inrae.fr/ppdo/sparql

ppdo.owl is the version of ppdo in OWL/XML format to use with Protégé.

ppdo.rdf is the version of the ontology in RDF/XML format to use with skos play.

The ontology engineering process used the Linked Open Terminology (LOT) methodology.

The engineering process was made using Protégé Cellfie plugin.
All the files used during the generation of ppdo.owl are stored in Cellfie directory.


## Phenological Scale of Grapevine

The repository grapevine contains the file that describe the phenological scale of grapevine based on ppdo ontology.

This dataset contains the 5 aligned scales of grapevine phenological stages. This work was made under the supervision of Xavier DELPUECH and Marc RAYNAL from French Institute of Grapevine and Vine (IFV)

## Phenological Scale of Cereals

The repository cereals contains the file that describe the phenological scale of wheat, barley, oat, rye based on ppdo ontology.

This dataset contains the aligned scales of cereals phenological stages. 

## Phenological Scale of Root and Stem Vegetables

The repository rootAndStemVegetables contains the file that describe the phenological scale of carrot, celeriac, kohlrabi, chicory, radish, swede, scorzonera based on ppdo ontology.

## Phenological Scale of Leaf Vegetables forming Heads

The repository leafVegetablesFormingHeads contains the file that describe the phenological scale of cabbage, chinese cabbage, lettuce, endive based on ppdo ontology.

## Phenological Scale of Solanaceous Fruits

The repository solanaceousFruits contains the file that describe the phenological scale of tomato, aubergines, paprika and eggplant based on ppdo ontology.
