HAL is a multi-disciplinary open access
archive for the deposit and dissemination of sci-
entific research documents, whether they are pub-
lished or not. The documents may come from
teaching and research institutions in France or
abroad, or from public or private research centers.

L'archive ouverte pluridisciplinaire HAL, est
destinée au dépôt et à la diffusion de documents
scientifiques de niveau recherche, publiés ou non,
émanant des établissements d'enseignement et de
recherche français ou étrangers, des laboratoires
publics ou privés.

& EVOLUTIVE

## Observations
Interdisciplinarity and semantic heterogeneity of Biodiversity data disseminated among many databases

<figure><img src="image_3.png" /></figure>

## Research requirements
Harmonized and structured terminological resources to retrieve and share data
Controlled vocabulary & semantic standards

## Objectives
Interoperability of databases in ecology/biodiversity using :

* thesauri & domain ontologies

* metadata enriched with semantic relationships to describe and connect concepts and perform reasoning on data

## The steps of the project

Partnership initiated in 2014 between INIST-CNRS and various research organizations on the interoperability of data in ecology (CNRS/CEFE, INRA/AnaEE, FRB/CESAB)

### 3rd STEP

<figure><img src="image_6.png" /></figure>

#### Creation of a research group on biodiversity semantics – GDR SemanDiv –

38 participants from 17 French and international research structures (CNRS, INRA, IRD, IRSTEA, MNHN, GBIF)

conceptual basis to stimulate research in ecoinformatics

reviewing of definitions; ontologization of thesaurus; mappings

to achieve
**data integration & reusability**

### 1st STEP

Comprehensive survey of thesauri in Environmental Sciences including European infrastructures

Complementarity and alignments in the LOD cloud

→ lack of thesaurus dedicated to Biodiversity

### 2nd STEP

Development of the Biodiversity Thesaurus

- bilingual and polyhierarchical

615 concepts

- compliant with semantic web (SKOS/RDF) and ISO standards

- aligned & open-access (Loterre, AgroPortal)
